Live video is the upstream out to the Clients. It's Avigilon.

 

The magic number on these boxes is supposed to be 250Mbps upstream and downstream combined.

how many cameras do you have connected to this box?

A few I have running in the field.

 

 

 

 

What software are you using if you do not mind me asking? Also is this only recording but live video is disabled?

First thing you need to do is figure out your hard drive read/write speed and then you can figure you many cameras you can throw at it.

 

I have one system with 28 total cameras with a mix of 720, 1080 and 5MP cameras. Right now FPS is at 10 and I could double or triple the camera count if I needed to depending on the FPS that the customer needs.

 

As for the ATOM box I was feeding it over 100Mbps of data without issue.

Here is another question.. sorry for so many questions just trying to figure this out which I think I am almost there.

Do you know of any software makers that can read/write to multiple drives at once? Wouldn't it be logical to say that if you can read/write to multiple drives at once that you can do much more now? Does that make sense?

It also depends if you are doing live viewing or not. Live viewing consumes a lot of CPU power.

You can do recording of 64 x 5MP cameras on a high end CPU, but once you throw in live viewing it will not even come close to that.

 

That depends on the codec your using

Best case scenario using H.264. What can you get?

I have used ATOM based machines to record 16 and 29 megapixel cameras. If you pick the right VMS CPU power will not be an issue. As you already figured out hard drive I/O is your limiting factor.

great. How many 16mp and 29MP cameras did you use per server and at what FPS?

This is the issue I see. I have never seen a single IP camera solution that can do 64 channels of 5MP recording. Even at 1FPS. even with disabling the live view wouldnt you still max out somehow on the read/write for the hard disk drives?

Hello, I have a question on IP cameras and hardware maximum limitation support.

Here goes and please ask me any questions about this because I am having a tough time finding out the "correct" answer.

Some manufacturers say they can record up to 128 channels of IP cameras. This is all fine but the thing is they never tell you at what resolution, fps, bitrate, etc. What I want to know is what is that actual thresh hold number in Mbps. It seems like this is the ultimate number that would be the defining factor in ANY IP NVR system.

I know this is hardware dependent... But let's go with best case scenario on today's PC's with i7 CPU, max ram, best HDD's, etc.

Also I know there is a difference with local live viewing and local recording as well as local recording and not viewing live on the NVR.

Any point in the right direction would be greatly appreciated as every manufacturer seems to have their own formula. thanks
