Whilst setting up an identical tracker I connected it to a standard 9v battery and its been running for 7 days so am confident it wont drain your car battery. !! Great Video. Very informative , Thanks
For your problems with gpscj site. I've had luck with NOT messing about with server settings. Other than the basic set up. I changed the apn my telco and changed the update time in seconds(1-180). I set mine to 180 seconds, it'll upload its own location every 2 minutes. Saving battery and data. It doesn't matter really; once engine is started and device is in active mode, the unit uploads data every 5-15 seconds. In disarmed mode, you'll won't be getting any vibration alarms. Only power cut. I don't have high hopes for that small lipo cell though, it might just fail outright when you needed it most. So hide it well. Chances are they won't be driving without a battery anyways. I use the relay to drive my keyless start kit. Since the rfid ring takes around 20ma as it pulses for the presence for key. It does this all day and all night, so this handy relay helps.
This is a great video thanks. I got one of these and I connected it to the battery but it's not sending me an sms back, do you happen to know what I am doing wrong? I have checked it and both lights go on when I insert the sim card and I have also tested it in a cellphone but it doesn't send me the sms back when I'm trying to set the configuration
Thanks for this analysis. I have been interested in one of these for some time and eagerly look forward to seeing you succeed in getting it working properly.
I've spent two days trying to get it to work with a web tracking application, to no avail here in Colombia. Putting the sim in and changing some parameters was simple enough. I'm in Colombia, and have a 4G sim that is supposed to do 3G too. I don't know about 2G Some say the tracker only works with 2G, but that seems a bit silly for a "modern" design. Anyways, the SMS messages come in and get sent back to the Admin cell phone. I changed all kinds of settings trying to "connect" with Yuntrack and Traccar. I'm not sure if the CJ720 is supposed to talk with the local carrier MMS or internet server. I downloaded the traccar client app to an Android phone, for testing of the phone's settings, and could get a location, but not any tracks when I walked around the block. Iffy stuff at best.
I will probably do it but I don't think I'm gonna succeed in configuring this tracker to connect so maybe it's best to wait and get another tracker so I can have a fully working system.
@@voltlog It might be simpler to just build your own? Even though it'd end up being more expensive and less stealthy... At least you seem familiar enough with car electronics to be able to hook it up somewhere it'd not be easily spotted.
This is a very useful and detailed video. I have bought several gps trackers and now have one of these to test. I want something I can attach to my motorbikes that is reliable and can cut the fuel. But where as the others need to be hidden and that mean the satellite gps function is less reliable, with this device I can have it exposed because it looks like a relay. I glad you dissembled the unit as it shows there is no physical relay but a MOSFET to switch the power to the fuel pump etc. It does draw 60mA in standby, so the bikes need to be kept on charge when not in use. It would be good if the GPS and GSM circuits powered down until movement was detected thus only requiring a few mA when in standby, but I do no if there is a command for this. Can you share the link for creating you own server? Great job. Thanks for sharing.
Yeah their documentation on this product is very very poor. Even today a year later. You are able to make the GPS tracker to go to sleep if you send "sleep123456 shock". Then it will only draw very few mA until the device is shaken.
Thanks for the instructions. Got it up and running in the UK on a giffgaff sim card. Works great, I wired the relay to the horn so if I am near to my car but can't find it exactly, I sms the command and switch on the car horn. Server is working on mine too. Mine is in the car interior behind the dash and the signal is fine.
I reckon based on everyone’s comments this device does not work efficiently. I also did notice the author does not reply or assist anyone so it’s a 👎🏾👎🏾
Thank you for your instruction that helped me a lot with my CJ780 device being very similar to th CJ720. I recently found out how to get online to the YunTrack server on my PC as well as on my Android phone YunTrack-App. 1. I found the IP address for the gpscj.net domain is 113.98.254.179 2. Set the device IP with the SMS - command adminip123456 113.98.254.179:7700 and you are online! Good luck
Finally, the comment I was looking for. Was worried that I cannot configure it to a server of my choosing. If it allows me to change server & port, I should be able to work it
Thanks for the great video I recently purchased one of these and will be installing it soon... I am looking forward to more videos like this one and hope to see that video about the server soon soon.... Thnks

Got this today tried setting it up with my phone but get no response, do I need to use country codes or should I reset and start over ? The app works and so does the webpage no issues
Set your own external IP-Address and check the Firewall on wich port the tracker tries to connect. Then set a forwarding for these port/ports to your own internal Server and analyse the traffic with wireshark. I think this tracker posts it's position via http. No encryption or other complicated stuff. It seems to be port 7700.
I have very bad experiences with 12v car batteries and GPS trackers regarding the power consumption.... you said that this tracker can automatically go into sleep mode... did you send an SMS command to enable this function or is it enabled by default? moreover, did you have any luck with server?
I bought one and have the same problem as you. It adds a prefix to the server and so the server cannot work properly. I am in contact with the seller and will let you know if I have helpful feedback.
Got one of this installed. All worked well (ofcourse "Chinese well"). Left it for a few months in the car, without a Sim card and with a discharged main battery. Now, when I want to use it and plugged back the Sim , it doesn't work. The LEDs don't go on.... Where should I start looking for a fault? The black/red wires measure 12v
How do you mount it to receive the GPS satellite. It can't possibly be mounted under the hood. No clear signal at all! The last few years I've mounted them under the dash on the right side usually using a puck style antenna. This design would not fit.
I had a gps tracker about 5 years ago, command and control system looked the same, unit itself was very different though. I remember a similar issue with the server connection, it was something to do with the command being sent, I just don’t remember what it was.
yeah, I'm not sure I'll ever figure this out because even if I setup my own server the tracker is still going to be pointing at the wrong address the way I see things..
Wow! All of that for $14? That is a very interesting device. I wonder how easily it can be hacked to send data from added sensors. It seems like an ideal node for any sort of IoT needs.
Other trackers run Android on a cheap mobile phone soc and those can be hacked but I'm not sure it's the same here because of the lower power of the device, this is likely running a lower power microprocessor.
Looks that some setting like timezone or update time are not changed even if the module responses ok to a command. Can't get any sms alarm when armed. I.e. expected to get an alarm when acc gets +12V (simulating someone tryining to start a car), but with no result so far. Once got shock alarm. Due to exremely long lag on sms responses, can't rely on this thing.
It doesn't work at all, unless you open the hood. However, when it can't get a GPS lock, it will determine the position by triangulation of the cell signal, which, of course is far from precise.
D Stanoev unless you attach it to the wheel sensor sys....... Hehehehe you are absolutely that ex to track haha then sell the information to people on the dark web for quick cash......... It's that simple ... If you get your oil changed or your car serviced a slip of less than 100 bucks and your everything is available. Get used to it or service your car yourself. .. and under a hood ........ Just snip the ground . And it's now a a receiver. You won't get that.
What kind of tracking device would you recommend for my equipment trailers that would allow real time tracking should one of my trailers be stolen? Thanks
Yes, I'm having the same problem.... No tracking from the website..... Long term, I would LOVE to see how to send the data to my own web address and how to set it up!!!

My phone tracks great but their WEB site and phone application still show me in China, Not PA, USA. So, I am having the same problem. If I get it resolved I will let you know. Thank you for the video.
The only thing sad about these modules in general is that some countries have started to shut down 2G and 3G networks, leaving 2G only for certain private corpo services.
I have the kl720 car tracker was working well with message and iPhone app LKGPS2 very well , unfortunately the app tracking just stop working after I disarm it on the app , after that I can’t re-arm it The phone number in the tracker call my phone at times indicating something is going on Not sure what’s happening but would really like you to help me setting it back to normal
This device most likely uses gprs but in the US carriers stopped providing gprs service long time ago. Moreover, even 3g is obsolete. For example, at&t 3g works in the central part of the US and doesn't in the east one. We need gps tracker that supports 4g/LTE data.
Here in Romania there is no indication 2G will be decommissioned soon but if you need 4g, you can find 4g enabled gps trackers on aliexpress, just have a search.
Bought a tracker identical to this for use in the UK and a lot of the commands I have been trying to text it simply just don't work, then If I ask it its location it just returns "NO GPS" Thought it may be a iffy unit but bought 3, and all 3 are the same, very odd...
That's an interesting product. However, putting one in typical car relay places like under the hood or down low at the driver side can affect negatively gps and sellular signal.
Please note that there is a huge security risk when using these cheap chinese trackers! All of these cheap trackers are manufactured with sequential ID numbers and the same “123456” password, meaning that anyone who knows the ID of one tracker (your ID is shown very briefly in this video) can easily add or deduct numbers and input them along with the standard password, thus gaining access to track your whereabouts and even shut down your vehicle, if the tracker has this function and is connected to the fuel pump or ignition system. I’ve also found that the standard password along with the reset command is able to reset some (if not all) of these devices via SMS from ANY number, even if the standard password has been changed and an admin number has been set on the device. The first thing one should do to mitigate these issues is to setup their own traccar server. NEVER use the default chinese server! If you for some reason decide to use the default chinese tracking server, please note that changing password via the server is not the same as changing the device password via SMS command and vice versa. But still, change the website password IMMEDIATELY! Always chage the default password on the device via SMS command. Never give anyone your number to the tracking device, NEVER! I tried the above method of adding or deducting numbers to guess other tracker ID’s for people who still used the chinese tracking server, and some people fill out the section on the server containing contact details of the owner along with the tracker phone number... This could essentially enable someone with bad intentions to get info about the owners name, private and work addresses, e-mail and social media accounts, pictures of them, who they hang out with etc. And worst of all, shut down their vehicle while driving, potentially causing a fatal accident. The servers also keep a log of all the places you’ve been with the tracker active, and with some users I could go back several months and see their whereabouts on a daily basis, especially if their model of tracker was a wristwatch.
thanks! this is good info and good practice, however I'm never using the tracking devices shown on these teardowns in real life. I have already done a follow-up video with how to setup your own tracking server, it will be published soon.
not sure about that one, better get the ST901 tracker. I ordered this one on amazon but a nasty seller sent out aC13 to many buyers, never worked so I ask them to shut him down. I will try the ST901 now with Sino software, not sure, should work without too I guess

You should test the circuitry out to see if it will cut out and quit charging the Lipo at the right voltage 4.2V. Max.... that way it doesn't go boom!

have a great day
My phone tracks great but their WEB site and phone application still show me in China, Not PA, USA. So, I am having the same problem. If I get it resolved I will let you know. Thank you for the video.
did you ever fix this
No@@zachbrenneman4157
The only thing sad about these modules in general is that some countries have started to shut down 2G and 3G networks, leaving 2G only for certain private corpo services.
I have the kl720 car tracker
was working well with message and iPhone app LKGPS2 very well , unfortunately the app tracking just stop working after I disarm it on the app , after that I can’t re-arm it
The phone number in the tracker call my phone at times indicating something is going on
Not sure what’s happening but would really like you to help me setting it back to normal
This device most likely uses gprs but in the US carriers stopped providing gprs service long time ago. Moreover, even 3g is obsolete. For example, at&t 3g works in the central part of the US and doesn't in the east one. We need gps tracker that supports 4g/LTE data.
Here in Romania there is no indication 2G will be decommissioned soon but if you need 4g, you can find 4g enabled gps trackers on aliexpress, just have a search.
Bought a tracker identical to this for use in the UK and a lot of the commands I have been trying to text it simply just don't work,
then If I ask it its location it just returns "NO GPS"
Thought it may be a iffy unit but bought 3, and all 3 are the same, very odd...
Same with mine
On mine, the power down alarm doesn't work anymore even after sendinq "pwd1" . Any idea ? The lipo battery seems to be Ok.
That's an interesting product. However, putting one in typical car relay places like under the hood or down low at the driver side can affect negatively gps and sellular signal.
I was thinking one could install this under the dashboard and get good reception.
Very interesting. Thanks for sharing !
Please note that there is a huge security risk when using these cheap chinese trackers!
All of these cheap trackers are manufactured with sequential ID numbers and the same “123456” password, meaning that anyone who knows the ID of one tracker (your ID is shown very briefly in this video) can easily add or deduct numbers and input them along with the standard password, thus gaining access to track your whereabouts and even shut down your vehicle, if the tracker has this function and is connected to the fuel pump or ignition system.
I’ve also found that the standard password along with the reset command is able to reset some (if not all) of these devices via SMS from ANY number, even if the standard password has been changed and an admin number has been set on the device.
The first thing one should do to mitigate these issues is to setup their own traccar server. NEVER use the default chinese server!
If you for some reason decide to use the default chinese tracking server, please note that changing password via the server is not the same as changing the device password via SMS command and vice versa. But still, change the website password IMMEDIATELY!
Always chage the default password on the device via SMS command.
Never give anyone your number to the tracking device, NEVER! I tried the above method of adding or deducting numbers to guess other tracker ID’s for people who still used the chinese tracking server, and some people fill out the section on the server containing contact details of the owner along with the tracker phone number... This could essentially enable someone with bad intentions to get info about the owners name, private and work addresses, e-mail and social media accounts, pictures of them, who they hang out with etc. And worst of all, shut down their vehicle while driving, potentially causing a fatal accident.
The servers also keep a log of all the places you’ve been with the tracker active, and with some users I could go back several months and see their whereabouts on a daily basis, especially if their model of tracker was a wristwatch.
thanks! this is good info and good practice, however I'm never using the tracking devices shown on these teardowns in real life. I have already done a follow-up video with how to setup your own tracking server, it will be published soon.
not sure about that one, better get the ST901 tracker. I ordered this one on amazon but a nasty seller sent out aC13 to many buyers, never worked so I ask them to shut him down. I will try the ST901 now with Sino software, not sure, should work without too I guess
What is the different of sleep mode, sleep time mode, and sleep shock mode?? Thanks
Hi. My tracker has expired. Any solution available? Thanks
they sell it with one year online service license.
Hi... I have CJ720 and it works perfect as tracibility but I cannot send comand... please help me how. thx
Nice video m8!! But you have to check the installation spot. If there is metal above the GPS then probably you wont receive good GPS signal.
k yf sure, any big metal surface would seriously impact the signal but I was thinking under the dashboard would be a good spot.
@@voltlog Can you extended the antena from the relay to the another place?
@@matematic7240 maybe but it would have an impact on antenna performance so it's best if used as is.
Check the apn settings, for the server functionality
Do you know how much data it uses per alert?
It says my device is expired what is the solution pls. Tnx sir
Would this work on a escooter ?
