Thank you for your information. Also the OLDER the hard drive, the LESS Dependable they are! I learned this lesson the hard way. I had a theft I needed recorded, only to find out my old 6 year old hard drive went "Belly up"!
I like how you presented how compression works with paper and I understand that you did not want to go into in depth explanations on how it works to keep it simple. However, H.264/265 etc I believe would be a Temporal type of compression. So instead of compressing the entire frame (which would also make file sizes bigger) what H.264 does is it looks for similarities in frames and removes redundant information. So you would have a I-Frame or Key frame which is the full picture and is captured as the entire frame and then next 29 frames are just the updates. Then the process repeats. This would be known as GOP - group of pictures.
Damn, Hands down the most comprehensive and easy to understand and follow videos that I have ever watched concerning security systems, thank you so much for sharing this valuable information.
I know you do surveillance, but I live in the woods. We have deer, turkey, rabbits and on occasion a bobcat and bear. I have game cameras set up, but the night vision is poor. They have great color during the day, but few animals are active when the landscape is well lit. Do you have a few videos that would be of interest?
i have a question sir. I am running the blue iris with 2TB. i want to get an external HD but not sure which one to get and what connection type. also looking to record atleast 3 weeks to a month of video. 1. what connection should i get, 3.0 3.1, thunderbolt, ethernet? 2. should i get one 8-12TB HD or 2 to 3 smaller HD like 3, 4TB? 4. what manufacturer do you recommend? i am not finding an external hard drive thats made for continuous recordings. thanks to much for a response.
You could expect a typical PC HDD to fail much sooner than a HDD designed for CCTV use. Since CCTV HDD's are designed for 24/7 reading and writing, where a PC HDD is not.
Hey Danny, We've never carried Sonnet NVRs or have experience with Sonnet products. You may try reaching out to them to see if they can provide you the proper troubleshooting instructions to get playback!
SSD's can handle a limited number of write cycles, before they completely, and usually quite suddenly stop working. With normal usage, that limit gives you a few years of usage, but since surveillance systems are constantly recording (writing) in a continuous loop on multiple streams, that limit happens a whole lot sooner, and you would need to regularly replace your pricey SSD's. Regular HDD's also battle to survive the continuous writing. Stick with Surveillance HDD's.

H.265 is hard on cpu usage. So if your running it on a lower end end user pc they can have issues streaming or reviewing footage
so glad I found your video. It has saved me all the hard work doing the numbers and answered my questions. Cheers
Amazing video and the calculator tool is up-to-date and still functional in mid-2023! You are awesome my man!
Thanks for checkin it out and we're glad it was helpful!
this guy needs more subs. Excellent work sir 👍👍

Hey there Frank!
Id recommend checking out our NiteColor cam -> ua-cam.com/video/6WT5O4Ubf8Q/v-deo.html
"we're about to get nerdy"... subscribed! lol
Helps me a lot.. Thanks, mate! 👍🏻
Great video! Thank you!
On using the linked calculator, the disk space requirements do not reduce when reducing the frame rate below 10fps. Why is this?
Thank you great information.

very very good video
Hi mate how long does a 1tb can store & record on 1080p@ 60hz
What happend if I use computer HDD instead of CCTV HDD ?
You could expect a typical PC HDD to fail much sooner than a HDD designed for CCTV use. Since CCTV HDD's are designed for 24/7 reading and writing, where a PC HDD is not.
really super! thank you!
Coming from Brazil to say: Obrigado!!
Hi Nelly team, Do all UNV Cameras and NVR have U Code ?
Hey there! they sure do.
Why not use cloud storage with the third party, is it too expensive?
Data Usage can be a limiting factor. A lot of ISPs can limit you to only so much data per month. It can be costly as well.
And AV1 is 30% more efficient than H.265
Sonnet nvr no playback

What about HDD vs SSD?
Typically we recommend HDD's since i dont believe there are any SSD's rated for surveillance use.
SSD's can handle a limited number of write cycles, before they completely, and usually quite suddenly stop working. With normal usage, that limit gives you a few years of usage, but since surveillance systems are constantly recording (writing) in a continuous loop on multiple streams, that limit happens a whole lot sooner, and you would need to regularly replace your pricey SSD's. Regular HDD's also battle to survive the continuous writing. Stick with Surveillance HDD's.
With a POE system, how far can a wire be ran before you need a booster?
PoE can run up to 300ft before you need any supplemental boosting
@@NellysSecurity nah Hikvisions camera do 300M boiii
About the only people who will need an export of your footage is the cops, they have h.265 decompressors.
You can find this tech in blueray players..... and.... But, BUT LOLOL
did he just say "butt cheese"?
Also hikvision ewww lol
5:39 - What is butt cheese?
We'll let your imagination determine that 😎
Im not from America. I guess, there's a Cheese on your Butt🤣
