- A picture says more than a thousand words. This is why the world is moving away from text to images and videos. We, as Makers, can profit from this movement because we get dirt cheap hardware to play with. And if it works with an ESP32, even better. Time for a closer look.
I am a proud Patreon of GreatScott, Electroboom, Electronoobs, and others.
In this video I will:
- Compare the features of the four boards
- Try to get all of them working. Here we will see that we have to overcome the usual obstacles
- Try to use the new class of I2S MEMS microphones presented in my last mailbag. Two of the modules have such a microphone included
- Try out two sorts of camera lenses

The ESP32-CAM has an SD-Card slot. And a big white "flash" LED.
Maybe you should ad that no cats were woken during the making of this video ;-)
I have installed a ESP32-cam with removed IR filter and a few IR LEDS in a bird house! It works very well. The only thing is that i never saw a bird inside... :\ I also know that it need a lot of power otherwise you get the brownout message. So you must powered it on the VCC pin with 5V.
How and where did you get cameras with the IR filter removed
I see you have the same cat accessory on your workbench as I.
I have one too. In electronics you really need a mobile static electricity generator -- it makes life sooo much more interesting!
The CameraWebserver Sketch is very basic and afaik only uses one CPU core. Maybe we could split the workload of the MJPEG compression among the two cores? (e.g encode odd frames with Core1 and even frames with Core2). That would maybe boost frame rate and performance quite considerably? Cheers!
that would be really cool. Currently performance is pretty bad on these, even at 1080p.
If only there is a board with 2 way audio, camea and pir then we could do a smart door bell like the Ring smart camera door bell. Instead of paying a monthly fee to record to their cloud account we could record video to a home lan based nas or server.
Exactly what I would like to do with these boards.

Me too
Me too!
I'm also considering a ESP32-based intercom with ability to unlock an electric lock remotely.
A suitable project wqould be to put it in any focus of a telescope, for example a follower, mounting the cam behind lenses from a scrapped binocular, making it send signals for a motor driven mount to follow a certain star.
Interesting application!
An idea for a future project might be a video doorbell. Maybe using an old tablet and one of those esp32 cam with audio modules.
Good idea!
@@AndreasSpiess Great video. This is the exact project I want to build. Do you know if you can easily get the rtsp stream from the camera?
It would be useful to know their mA used while streaming video over wifi, recording on card and sleep/low power mode (with PIR active), That would provide an idea about how big a battery/solar panel they need in different remote camera applications.
cezar t I managed run the second board on a single 18650 3000mAh for 6-7h. The module gets quite warm. It’s clearly not very power efficient. I wasn’t even streaming anything just run the example sketch.
I really like your 'invisible hand' pointer. :)
:-)
Great video. Suggestions: OCR/ANPR. Take picture or trigger a relay (and send email/sms) when a certain partern (license plate or random word/sentence) is detected. I've put Weinheim on my agenda. However, not sure if my wife agrees on my (short) travel.... but it's worth trying.
Im trying To do a diy „Ring“ doorbell
With the white ttgo..
Living in a Rented flat im only allowed To take pictures / Video Stream when the doorbell is rung.
My Plan is To use the camera in the nametag of the Briefcase. And Be trigered By My doorbell and Send a Notifikation To My Smartphone (iobroker as connect Point)
Same issues with the poor Dokumentation
You can try with github.com/lewisxhe/esp32-camera-series
Thanks for another great video. I have been toying with the idea to use the esp camera module to control a sprinkler turret to target garden pests like deer or racoons. First start with basic aiming. Then see object recognition so target deer an not people.
Forgive Andreas, a microscopic correction, the ESP32-CAM is equipped with an SD slot.
On the net I found a couple of working sketches, but I haven't yet tested thoroughly ... there is no time!
Byyyyyeeeee. :)
Really? Then it could be useful for my purpose. If only it had an IR-CUT filter...
@@GRBtutorials why you want an ir-cut.....that pir hurts you?
Oscar Il Mio For surveillance during the night. I’m looking for an IP camera, and I don’t want it to spy on me, so I’d rather use a firmware I can control or use Ethernet instead of Wi-Fi (the problem being that I’d have to run cable through the house, and something that isn’t easy in mine). Both can be disrupted (by cutting the cable or using a jammer), so having SD card backup would be nice.
@@GRBtutorials Only Oscar plz ;)
So, there are many IP cameras on the market that use an SD card to save data, simply connect the camera to a small, correctly adjusted access point, or use a do-it-yourself lan-wifi interface to connect the camera to your wifi.
About ESP-CAM, yes, it has an integrated SD slot, but I haven't tested any of these potentials yet.
However, if you want to start somewhere, start with Andreas's tutorial and mix it with the one in the link below.
ua-cam.com/video/36p9To2hfak/v-deo.html
If you pay attention to what is said, the limitations are inherent to the sketch, so then it is up to you to develop something more suited to your needs.
Finally, if your camera's PIR annoys you because it hits the lens, well, learn from the traffic lights ;)
Sorry Andreas for the "o.t."...
@@GRBtutorials randomnerdtutorials.com/esp32-cam-pir-motion-detector-photo-capture/
This can be usefull too.
I have a big question for you Andreas. Do you confirm GreatScott's statement that the camera modules salvaged from the high-end smartphones are unusable for amateur makers? Due to unknown specs and protocol.
Very useful roundup. A Pi Zero + cheap cam + sd card is in the same price range though so I will stick with those for now.
Its really hard to use anything other than a pi zero now they have put wifi on them.
what I was thinking. the esp32 is a bit limited for video work.
Wait, esp32-cam (2nd tested) does have microSD slot, right under the lens...
It should well fit in sleep phase detectir device. The board and camera are small enought to fit inside some kind of eyewear to detect movement of an eye, so you can know it is a fast sleep phase of dream. Kind of IR backlight is needed.
Maybe you try it. Sounds interesting.
For the TTGO White, have you tried using:
#define Y8_GPIO_NUM 37
#define Y7_GPIO_NUM 38
This works for v1.62 with mic, I see that you have v1.6 in the video which I think is obsolete.
Also for others in case it is not known, these devices require a lot of current so on USB power they tend to brownout if your USB port is low power. You need to supply power with a 5V adapter.
Thank you for the tip!
Either you are a very brave and trusting Cat owner, or your cat is tech savvy and knows how to avoid destroying your lab!
My lab is a mess, especially behind the scenes. So far she did not destroy anything. The only disadvantage: I everwhere find hairs...
@@AndreasSpiess - Makes me wonder how many parts, cables and such are _under_ the cat.......
I have came across use cases of tinyml with sound and image recognition on arduino boards. One very useful project is to use these boards for utility meter readings. Esp32 boards are capable of character recognition, more especially so when only numerical characters are involved
I saw these meter reading applications, too. But we already have a smart meter. So I could not test it :-(
An idea for these boards might be as long term timelapse camera. To document a 6 month house build or similar. Would require extremely low power optimization (your favorite 😁), solar and batteries etc.
I think you already find such projects including code.
Its always a good day when we get cats!
Super helpful, but you got the like for the little finger pointer :P
It seems to have more fans than myself ;-)
I got esp32-cam working with MicroPython as well. It takes a picture and emails it to me.
That's impressive!
I want to do that in my project.
Can you reply to this comment with a link to micropython code that captures images or video (preferably at max resolution) from the esp32-with-camera board?
Thanks!
(Oh. I don't need code to do the emailing. I am looking for micropython code that will capture images or video, at max resolution, and save them to an sd card.)
Can you share code?
@@KenSkier sure, just flash the bin file from here github.com/Lennyz1988/micropython/releases/tag/v1
@@ivanarakistain3885 look at my other comment and look at the webcam module inside the bin, after you flash it.
NEW PROJECT you say? make your own Dji osmo with gimbal using raspberry zero, a display screen, mic, a good camera, indication led, in battery, buttons for control, you can place all this in your own 3D printed case, it should have the face tracking functionality.
These videos are so good! You can't imagine how much people you are helping and how much of a time saver this is.
Thank you!
It might be time to tidy your lab and remove the dead cat, Andreas :)
Great vid as always. Thank you.
These look really interesting. It'd be interesting to integrate this with my home automation setup. I'm wondering if I can use the TTGO White's PIR sensor for movement and, when triggered, use the camera to perform numberplate recognition. I could then notify OpenHab of a specific person coming home, and running a scene accordingly.
This is probably what they intend. And maybe you could even sleep the ESP and only wake it with the PIR pin
@@AndreasSpiess As the parent of two cats ... How about an esp project that would track how many different places our cats sleep each day and for how long at each location. P.S. Big fan of your work!
@@AndreasSpiess I used my TTGO T-Camera to attach a wireless camera to my cat. It is funny to see what he's seeing like when he spies you from strange places.
Great video Andreas!
I used the TTGo-White board for a doorbell using Home Assistant and ESPhome: ua-cam.com/video/jrpbQAdQNv8/v-deo.html
I have the TTGo-black too but I haven't been able to get the display working.
I have the ESP-Eye board too and I'm planning to use it as the "eye" on a Nerf Turret gun project. I've got most of it built but just haven't made it a priority yet. Maybe someday soon.
Thanks!
I have tried motionEyeOS on rpi3. Great for setting-up surveillance cams connecting on my network. Going to use it on my mobile toy robot school project.
I am also using the pi zero w + motioneyeos with a cheap camera without any lense for my DIY home security. The cost and setup ease seem to be much better than ESP camera to me. Am I missing something here?
If "a picture says more than a thousand words", how will you use your Swiss accent to your benefit?
he talk, a lot!
Wow! The remote cat disabler on your board really works. That cat is OUT! I have had no luck with mine so most of my remote camera projects end up as cat toys.
Maybe she needs more training ;-)
@@AndreasSpiessTraining is fruitless. I have concluded that she is stuck in a local optimum that cannot be escaped without a total software rewrite. On the bright side the cat toy market is larger and far more profitable than the tech gizmo/nerd toy market!
Maybe flashing the ESP32 using MicroPython and use OpenCV?
I do not think the ESP32 is powerful enough to do pattern recognition. I rather think this part has to be done on a more powerful machine. But maybe somebody will proof me wrong.
Andreas Spiess That sounds like a challenge! :)
I have tried both the USA and the UK stock on about 40 items so far, they take the same 20-30 days to arrive as the china ones, you just pay more for them.
Dear Andreas, first of all thanks for this overview! I have two remarks, one: I made ths ESP32-cam using an 0.96” oled display and one external button, making time lapse recordings. The images are stored on the SD card. I use the available GPIO pins with some tricks as they are in use for the camera and the SD reader. For example the TXD and RXD pins can be used as GPIO pins, and IO0 can be used as an input as soon as the sketch is loaded, I use it with a button and the touch command in my sketch. On the display you can select wether or not connect to WiFi (I did not yet add functionality to that as I do not have experience with building websites, but maybe somebody can help with that?). Then the user can select the interval for the timelapse on the display, and start te recording. As I am on a short holiday now I cannot give you the sketch, but I will do so ASAP.
The second point, I hoped you would give some more info on the little (round PCB) MEMS I2S microphone, how to connect and how to record. Do you have this microphone running on an ESP32? I would be very, very grateful if you have some more info on that!
Regards, Hans
it has been two weeks trying to load a program on my esp32cam followed all the youtube instructions but never seemed to get it past loading :( tried with a pins, tried with UNO but so far failed...
@@randolfllige9142 Did you press the rst pin before you plug in power?
@@binxu2674 No. Thank you very much! so far i was able to load via development board. Was not able to test the streaming due to office filters. Will try reloading again from outside the office.
@@randolfllige9142 good to hear. I am also a arduino starter. Cheers.
I've been working with the AIThinker esp32 cam for a while now. I've programmed rtsp from the web, snapshot on interrupt and streaming mjpeg that cam be captured with ffmpeg on an RPI, viewable with vlc. In all cases, I add a web configuration page and employ OTA with the Arduino IDE. It's a great little device for $7. I don't play with facial recognition, but it makes a great little fpv camera on my robot platform. Lot's of fun to come.
Hello, I'm interested by your work. Is it possible to share ? Thanks a lot.
I have a couple of ESP-EYE modules, which I would like to use to count peoples in a room. If anybody have a suggestions or link to a project, please let me know, thanks!
7:00 I think there is an error in the features table. My ESP-CAM *has* an SD card slot and you can even see it in your video directly beneath the camera module.
You also state that the TTGO modules *don't* have GPIOs but then in the table you list 2+2 and 2 respectively - what gives? 😎
You are right. I already corrected the sheet and pinned a comment.
Great Video... And I saw you also have a great video on the TCA9548A I2c multiplexer... I am working with a ESP32Cam with OV2640 cam but wanted more gpio pins... for controlling a motor (L2N98 which needs: - ena , in1, in2 pins), a touch sensor, two limit switches, and a few push buttons plus a few LEDs. Would it make sense to add a TCA9548A 1-to-8 I2C multiplexer to the esp32cam - then adding a GPIO Expander (MCP23016)... or what would you recommend? A tutorial would be cool - I am sure lots of people would love to have more gpio pins on this cool little board! Cheers. And great work!! Phil
You do not need a i2c multiplexer if you plan to use MCP23016. They have 2 address pins and you should be able to connect 4 of them on one I2C bus. 1 I2C bus supports up to 127 devices with different addresses.
@@AndreasSpiess Ah ok - that makes sense...now just need to figure out how to change the gpio pins be SDA and SCL...I am using the wire.h library but no luck so far....I need to do a bit more reading
Hi. I've enjoyed many of your videos and I just found this one. It's been a while since you posted this video but you invited comments on projects made with these cameras.
Last year I built a couple surveillance projects using the ESP32-CAM board and a PIR sensor. One is plugged in full time and streams video and makes pictures or AVI videos of activity in front of my garage and saves them on an SD card and emails them to me (github.com/mtnbkr88/ESP32CAMVideoRecorder). The other ESP32-CAM and PIR sensor is solar powered and streams video and takes pictures or short AVI videos of activity along my long driveway and sends a trigger to the full time ESP32-CAM to take pictures or video (github.com/mtnbkr88/ESP32CAMRemotePIR). I used a 3D printer to make enclosures for these projects. This is fun stuff.
I live on two acres in the mountains in California, USA now but I visited Switzerland back in 1998. It is one of the most beautiful places I've ever been.
Thanks!
Very useful video, thanks! I've been thinking of getting some of these boards, I have some project ideas very relevant here South Africa:
1) Intruder recognising security cam: Take pictures or a short video when sound is detected, and send it to a PC/Raspberry Pi/cloud service to do image classification to detect if a human is in the image. It then sends a alert and photo if a intruder is detected. Way less false positives than a passive security sensor. We have a very high violent crime rate, so it could literaly save lives.
2) Wildlife camera: For wildlife research in game reserves, it is a much cheaper alternative than commercial trail cameras so many more of them can be deployed. Photo's can be stored for later access or sent it to a GSM-wifi gateways. It can also be used to prevent human-animal conflict, like detecting when a lion/leopard/jackal comes close to livestock enclosures and send alerts.
Both of the above ideas can be tested in my immediate area, and I also have access to world class game reserves if you're interested, so let me know!
I'm also from South Africa and was also thinking of how this could be used in game reserves.
I had the same problem with the ESP crashing because of the camera - I just re-seated the flat flex in the ZIF connector and it worked fine after that
I tried that a few times and also changed the camera. Without success :-(
@@AndreasSpiess Don't buy the www.diymore.cc/ version of the ESP32 cam, mine came with a split ribbon cable to the camera which they suggested I solder back together, replaced the camera module and it will NOT stay connected.
ESP32 simply does not work good with camera sensor. So far there is some clunky i2s code that is not even written properly for i2s to operate at good resolution and speed.
Maybe someone who has ton of time will write some optimized code in lx6 asm and add it under idf. Forget buggy arduino
I was thinking some day ago as simple video stream for having look at remote analog sensors witch don't suport digitalization. Like thermometer on old furnace.
Mayby some image resolution things can digitalize shuch sensors.
Tomasz Durlej I would like to have recognizance of number on a LCD display. As a a result many measurement devices could be dizitalized and connected to the web for data reading. Can somebody help?
ESP32 cams + 1 raspberry pi + motion eye???
My white TTGO camera with SSD1306 OLED was working, often I use the target ESP32 DEV Module and enable PSRAM.
Also the motion sensor worked fine, my model hat no BMC nor any mic soldered. Here are the pins for the camera: (of course I defined CAMERA_MODEL_TTGO)
#elif defined(CAMERA_MODEL_TTGO)
#define PWDN_GPIO_NUM 26
#define RESET_GPIO_NUM -1
#define XCLK_GPIO_NUM 32
#define SIOD_GPIO_NUM 13
#define SIOC_GPIO_NUM 12
#define Y9_GPIO_NUM 39
#define Y8_GPIO_NUM 36
#define Y7_GPIO_NUM 23
#define Y6_GPIO_NUM 18

#define Y4_GPIO_NUM 4
#define Y3_GPIO_NUM 14
#define Y2_GPIO_NUM 5
#define VSYNC_GPIO_NUM 27
#define HREF_GPIO_NUM 25
#define PCLK_GPIO_NUM 19
I spend some more time to investigate into camera options, capering images on my own and decoding the HTML page.
Please note that the low level camera support is included in the IDF SDK as a binary library and not as an Arduino library source. There are other projects with complete Arduino source available. The true disadvantage is that the ESP32 has little PSRAM and after a few frames it is full.
Great video as always, Thanks Helmut
Thank you for posting your pin numbers. Unfortunately, it also did not work :-( Maybe there are more versions of the same board available. I used this diagram: github.com/Xinyuan-LilyGO/esp32-camera-series/blob/master/schematic/OV2640_V16.pdf
I do not think pattern recognition on the ESP will lead to good results. I rather think it could be interesting in conjunction with an RPI4 or a Jetson Nano. Then the ESP could provide the pictures and steer local actuators.
I think your board is this one: github.com/Xinyuan-LilyGO/esp32-camera-series/blob/master/schematic/OV2640_V05.pdf
Is there any performance difference, or just the different modules bundled with the board?
Andreas alles gut bei dir ? Machst du Urlaub ? Ich vermisse dein Sonntags Video ;-)
Alles ok. Danke der Nachfrage...
Excellent subject and video, Andreas!! Have you experienced a very high heat from these cameras? I used one with esphome, heat is quite high. I think you should consider furthering work on these because very few people have gone to complex topics such as wake from deep slip, trigger of picture taking, or output switch of relay from a detection...
They get quite hot. This is why the combination with a PIR might be interesting. Then you can deep-sleep the ESP and only wake it up when movement occurs. We will see if we will find more work on these modules other than showing the demo mode ;-)
@@AndreasSpiess super, looking forward to your next findings!!

Hello andreas,
I have a esp32 devkit v1 30GPIO version. I am facing issue when providing power to vin pin from external power supply(+5V). esp32 board show power on led but its sketch doesn't start until I press reset(EN) pin. Can you please help me to provide some information on this issue.
Unfortunately, I cannot do remote debugging.
For face recognition and wifi you may be more interested in the K210 boards. I think there is also an M5StickV+ coming up with WiFi as an upgrade to the M5StickV (careful the mic does not work in that one)
A video featuring the Sipeed Maix Risk V you got in the previous mailbag is welcomed!
In the meantime, I also have the M5stick. Just need the time ;-)
Lack of available time is a challenge we engineers share...
Andreas, have you faced with the PSRAM ID read error: 0xffffffff issue? esp32-cam module with 4MBpsram can not use it. If you could advice any solution how to fix it/ Thanks
I never had this issue. Google has some hits if you search
Can be used for optical character recognition for water meter.
I do not know. Maybe you find a project?
Wifi-doorbell, camera, PIR, perhaps add 2way-audio: Just add the legendary ASPT (AndreasSpies-Powersaving-Tricks), then it would make a platform for features not seen in the market so far... and all without nasty monthly cloud subscription fees.
Good afternoon Sir. I just found your channel and it is awesome! Is there any reference for the thesis you were the expert that you commented at the beginning of the video? the one about using esp32-cam to count people in a conference room... Or do you have any tip or tutorial for something similar? Thank you for sharing your knowledge!
I do not know if it was ever published. I saw some tutorials for the ESPcam and video transfer, but I do not remember where
I know this video is quite old. Looking for a similar low cost board that will be able to take full advantage of the camera. Have read that due to low memory the quality is severly hindered.
I think they still sell these boards and I do not know of newer or better ones.
Glad you showed the ESP32 Camera you don't own, but you missed at least 3 other ESP32 based cameras made by M5Stack - They have one that looks a lot like the ESP-Eye called the ESP32CAM it has a Grove connector on it so breaks out G/5v/G13/G4 nothing remarkable about it, but it does work out of the box, and works quite well. I think it runs around $8, There is the M5Camera, which is in a case and has lego mounts on it, It has a gyroscope, and pressure sensor, and Analog Mic, and a Grove connector to break out the I2C pins this one is about $15, There is a M5CameraF which I think the difference is the fish eye lens, Looks like it's in a different style of case too, I'm not really sure it's about $17 dollars. I'm still waiting on a couple of them from China, but they claim QR code/ and Face Recognizing. I don't think any of them are supported by the Arduino IDE just yet, just the ESP-IDF. Just thought I'd mention a few more.
I would like to use the camera for meter reading with some sort of ocr
This something that I'm currently working on. Take the picture of the power or gas meter every 28th day in the month and send it to my e-mail
Great video! Thanks. I have a question about the chart shown at 04;20 - detailing the Esp32-cam . It says no SD card slot is available. I'm holding this exact same board in my hand - and there clearly is an SD card slot . I haven't checked that it works but I'm sure it will.
You are right. I pinned a correction post as the first comment ;-)
If you ever do another review of these types of camera devices could you please show us the low light level ability of the unit. Thanks for video's there away full of useful info and no BS.
I think they are bad (very small sensor). But maybe without an IR filter, they could be used with IR illumination?
This is exactly I am planning to do. Looking for a very optimized way and do most of my compute on the Controller.
Very good!
Did you find out how to stream audio with ESP32 by now? Would be really interesting for one of my projects :)
I never investigated further. But maybe you find a project on the internet?
@@AndreasSpiess Sadly not (at least not if I want to receive it with Standard Software like VLC or in a browser), seems to be a bigger problem. I want to build some kind of baby phone streaming to the browser on my Smartphone :)
Been using ESP32-CAM module for two weeks now, I'm kinda dissapointed. The video quality is rather poor, even with good light, fps is poor (it's rather seconds-per-frame). AND it sometimes hangs (can't access it in any way, no stream/image available, then after few minutes it works. Sometimes it needs reset). Also the module itself runs very hot (which might cause the earlier problem).
I'm running tasmota firmware on it, so it might be why it doesn't work as stable as I would like to, but can't imagine that better/less bloated firmware would miracly cause the image quality/fps to become better now.
Tl:dr It's nice fun n cheap gadget, but don't expect anything from it.
Agreed. Not many useful projects were made with these boards.
hi @andreas spiess, which camera would you recommend for a facial recognition,
must also have the best low light performance
Thanks

I am no specialist in video applications.
I have only tried the esp32-cam boards (the $8 version) with only moderate luck. What I would love to see is a stripped down version of opencv on an esp32. Specifically i would like to use esp32 cameras to get distances to apriltags. That would be a much cheaper solution than using a raspberry pi.
I am not sure if the ESP32 has enough power for this job. Maybe the -S3 with its vector commands can help here...
Great video again. My project will be a doorbell camera, where a Rpi does the motion detection on the camera.
When someone is detected or the doorbell is pressed it will send a Telegram message with the picture(s)
I have a white TTGO board which does not have a mic.

I know the camera works because I use it to keep an eye on our mailbox from the computer.
I don't know the above pins are correct because I haven't changed the code in the module since I received it. I just use the module as it came.
Hi
I was wondering if it is possible to add external microphone inmp441 to esp32 cam since it comes without any microphone
I uploaded scout32 code (mini track) on it and it works good
Now I would also like to have some audio too 😁
Just google "inmp441 esp32"... It seems to work.
I like the idea of using a camera as a user input device… There are many ways it can be done, using just that as your premise. One way I've considered, is using an object with a QR Code printed on it, which the camera can track. You can even use multiple QR Codes with unique IDs encoded in them. …Three things to consider, though, are the latency of the camera and video processing steps, the FPS, and the pixel count (or resolution). Latency will lead to an experience that feels slow and unresponsive. Low frame rate will lead to motion tracking errors with fast movements. A low number of pixels will mean less detail, so you'll need to compensate with larger QR Code labels.
Anyone is free to use these ideas, by the way! I kinda hope that someone does something with it.
Early this year I put together some resources on Esp32-cam for Esp-IDF.
There's a nice sketch to upload pictures to Google cloud storage and some others.

Hast Du eine Idee?
Du musst das Board offenbar speziell anschliessen: randomnerdtutorials.com/esp32-cam-troubleshooting-guide/
I recently got the M5CameraF that is neat and comes in a little plastic case. It has some example code for face recognition but in esp_idf github.com/m5stack/m5stack-cam-psram
AFAIK they do not support Arduino IDE. So it is not suited for this channel :-(
Hi, Is it possible to program these cameras to do the following: 1. Stream to youtube directly 2. Record the video Locally 3. Motion/Sound/time lapse Recording 4. Compile/Join the videos automatically 5. Auto Upload to Google Photos. I have managed to do these things on a PC based system and the idea is to document and record my entire family's activities and store it on cloud. Akin to having a digital life after I am long gone!!!
Maybe you google if you find a project for each purpose. Working with Google services is not always easy with these small devices (Authorizations)
What many do not know. You can't really use the esp32 camera productively. The power consumption is very high.
The following workaround: The camera takes a photo every 60 seconds and sends it to a web server. With a 2,000 mA battery, the camera would not last 5 days. That's very poor compared to, say, Arlo or Eufy. Even a 10,000 mA battery would last a maximum of 25 days. I calculated here with a deep sleep mode and that each waking up, taking a picture and sending the picture takes a total of 5 seconds. Extrapolated to a day, that's 120 minutes and with a consumption of about 200 mAh, that's 400 mA daily. What does the professional say about this?
I do not see video as a low-power application and would go for a mains connection for longterm usage.
I found this not quite as good as your usual comparisons. In fact its quite bad, maybe you are busy I had been worried. The bad part is about comparing student projects as clunky and perhaps not up to par but them using a raspberry pi instead seems far superior to an esp32. It was like a name drop and then a diss all in one. Not upset as much as disappointed. Not everyone is perfect all the time and I think its obvious that you are busy on something but I would have been more interested in your work with the school, your upcoming speaking events, or a generic update instead of whatever this was. Don't feel bad about it please, its only my opinion and you know what people say about opinions. Hope you are well.
Last year I've got a pair of ESP32-CAMs, my project idea was to take photos periodically, detect changes (movement) and than send a photo to a server. The examples I found were not much documented or stable. I got to the point of taking photos in 320x240 (to minimize memory and processing), converting them to grey-scale, comparing them and, if a certain number of pixels changed, take a 1600x1200 photo and save it to the SD card. There were crashes and mysterious errors during development, the end result was not great. So I lost interest in the project. Another annoying thing thing with the ESP32-CAM is that the bright white LED is connect to one of the pins used for the SD card, so it blinks when you access a card.
I also came to the conclusion that these boards were overhyped. That is why I never used them afterwards :-(
I got the TTGO_White to produce a picture with these settings:
#elif defined(CAMERA_MODEL_TTGO_WHITE)
#define PWDN_GPIO_NUM 26
#define RESET_GPIO_NUM -1
#define XCLK_GPIO_NUM 32
#define SIOD_GPIO_NUM 13
#define SIOC_GPIO_NUM 12
#define Y9_GPIO_NUM 39
#define Y8_GPIO_NUM 36
#define Y7_GPIO_NUM 23
#define Y6_GPIO_NUM 18
#define Y5_GPIO_NUM 15
#define Y4_GPIO_NUM 4
#define Y3_GPIO_NUM 14
#define Y2_GPIO_NUM 5
#define VSYNC_GPIO_NUM 27
#define HREF_GPIO_NUM 25
#define PCLK_GPIO_NUM 19
Hope this helps someone.
Thank you for sharing!
HELP! - I received my ESP32-CAM last week and have been struggling with it. I had some issues programming it at first; but, that seemed to have a problem with my USB-serial. I got a new one and it programmed right away. I then had to figure out which "CAMERA_MODEL" to use for CameraWebServer. CAMERA_MODEL_AI_THINKER works (I think) - at least no error. Now the challenge I have is getting the IP address. When I use the USB-serial in 3.3V mode I get the "Brownout detector was triggered". I assume this is because the USB-serial can not supply enough current. Anytime I try to avoid that by posewering the board using 5V on the VCC pin, the LED turns solid on and I get no message out of the serial port.
You are right. I do not connect 3.3v from the FTDI adapter and power the module with 5v. GND has to be common
I'm trying to figure out what would be the best cameras to use for my project. I built a remote control snow blower using a 10 channel Flysky RC connected to a mega 2560 pro micro. I want to add a 360 birds eye like they have in cars. That requires streaming 4 cameras. I thought of using a car system that has its own video stitching and processing, but I don't know how I could send the video signal over wifi. If using esp32Cam I would need real time video stitching software. I looked at the M5Cameras from Marcus Tarquinio reply, but the ap only supports 1 camera at a time.
I also never saw a project with 4 ESPcams running in parallel...
Surveillance, so I got one of these to play with. It economics though dont add up really. The unit costs around $10US + shipping for 2MP excluding a power source. If you want a "better" wide lens camera add $1 to $2US so $15US+ all up. This setup is however without a case and not weatherproof to say the least, meanwhile you can buy a ready to go complete 3MP or even a 5MP camera off aliexpress ready to go for around that.
True!
I think the TTGO White board would be best for my project. Andreas, did you get the camera on it working? It looks like the pin-out is different for the version with and without the microphone. Maybe that's the problem in your code?
Were you able to use the PIR sensor on this board?
General question, has anyone tried connecting any of these cameras (or any other lower priced) to a cellular MCU board to have pictures send over the email or uploaded to a server? If so, could you share your set-up and code?
I never used it again. But you should find projects on google.
1.3" ST7789 in TTGO Black is not an OLED - it is LCD IPS used commonly in cheap BT watches :)
Andreas, not sure if you tried AMB82-mini. I watched your video 3 months ago and tried ESP32 Camera. But now I found this AMB82-mini could be a good alternative to try - want to know your suggestion.

I only once tried a Realtek WiFi chip and was quite disappointed about their software and documentation. So I will save my time. But maybe I am wrong this time
Andreas: "Please leave your project ideas in the comments"... here we go.
I think for a solar powered LTE camera, an esp32 instead of raspi zero would be less power hungry and therefore result in a smaller, cheaper device.
I need such a thing for river level monitoring: docs.google.com/document/d/1p398I5prpEqUVxoj-CzpbUMImztJaH_K8-nVY8LKkwc/#heading=h.qfkbn1mw634i
Any ideas on which specific hardware to use to try implement this?
I am not sure if the camera is good enough on this board. I read many disappointing comments and it pretty much disappeared (not much new projects are done with it). Maybe it is better to accept a higher consumption and add a bigger solar panel.
Merci Andreas. I am interresting for a video about I2S MEMS Microphone with esp32 if it is possible?
Hi Andreas. Do you know if it's possible to stream the video uncompressed. I've been working on a project that needs zero latency. I've worked out how to hack it together using a raspberry pi, but it'd have a smaller physical footprint and may be cheaper using esp32.
I have no experience with that scenario. But the ESP32 is not well suited for fast video...
I just bought 2 from Amazon that were very cheap.
I bought them to learn esp32. I've been dabbling with arduino but wanted cooler projects.
I cannot even get them to work.
It's been a headache.
I'm giving them away...
Lol
This is probably not my first choice for a beginner's board. Maybe you keep them for when you did a few simpler projects...
The low performance is really limiting. The only good thing is that it is cheaper than most IP webcams and doesn't require a USB capable host. But it does require something to power it and possibly an enclosure. I can see uses where we need an additional set of eyes without too many hazzles. Like monitoring animal cages/sleeping places. Or monitoring experiments. Or maybe for spectrophotometers and things like that.
These are the reasons I so far had no use for the module :-(
Is there a way to use a mobile camera if the mobile is damaged?
I do not know
Firstly, you are a great man. Thanks for the detailed videos. But I couldn't understand one thing. Which one is better for face recognition project to use. I want to open door with face recognition and send details over wifi connection to some other esp8266 boards. Which one you or anyone recommends. And is there anyone who used one of these products in such purpose for long term?
Thanks one again.
I never tried such a project, so I do not know :-(
I am working with cheap esp32-cam for a while now. They do have some odd quirks e.g. on at least two of my devices the camera stops working if it doesn't touch the sd card slot ... I have no idea why. I also can only program it if it gets 5V but not 3.3V. Multiple IO ports accessible don't seem to be usable e.g. IO16, Programming via Wifi doesn't work properly, ...
My plan is to build a security camera with wheels on it that either works like a remote controlled car or like a gondola on a rope having over my garden ;)
Great video, tkanks! Have you try to actually check the sound recorded via i2s mems ? They struggle a lot with RBP ('works' but super poor quality due to audio drivers and omega onion, where i2s don't work at all despite claims by the vendor)
I only looked at sound levels, not actual recordings as I have no plans to use it for that.
I went to a texas instruments lecture when they came out with the little microprocessor on a USB stick... they had a library that detects the sound of broken glass, I'm only a beginner but would love to have that on the ESP32... In 3 days I went from blink LED to TUNIOT to ESP32 cam working after about 24 hours of fighting.
Very good! I am sure you will detect broken glass in the future if you continue like that
@@AndreasSpiess Have watched many of your videos, greetings from Cape Town
Here is my modified code for the "white" esp32 camera module (the one with PIR sensor).
drive.google.com/file/d/1AmRhKDoz9yLCidewq4GAuxZjbG93vDbO/view?usp=sharing
You can use the included pushbutton for rotating the imagen and the display.
(needs to hardcode your wifi credentials)
I am looking for about your product place me a messages . when I post this . I am looking for more no this . How can I build some of these Chambers but I can use them for off-grid project property and income billing and I needed how can I make them Wireless or how can I charge them like from the battery or solar panel or like and camping or something
Unfortunately, I do not understand your comment :-(
I have a fishtank with abut 40+ Golsfish in an aquaponics setup. I am interested in installing a live feed camera and maybe add some pattern recognition to differentiate between fish (recognise individuals). I need to sort out the hardware first.
Nice project!
I got an idea to make, solar powered wireless spy camera, just like the one in the movies. We then, could deploy it anywhere hidden around the city, it would connect using modem to the internet. The real problem will be the project physical size, and power efficiency.
You are right.
