Internet upload speed requirement IP CCTV

[badfrog 0]

I just want to thank everyone at cctv forums. I've been actively reading and was able to setup a 48 camera IP CCTV system at my company's factory.

 

Now, I've run into alittle problem for the remote viewing.

 

All cameras record at 720p locally and substream CIF@15fps, bit rate best(I'm not sure if I'm using correct settings for live streaming). We currently have ATT U-Verse and trying to watch even 1 camera is jittery and not smooth.

 

I understand that trying to watch all 48 cameras at once would need a serious upload speed. So, we agreed that 16 cameras MAX for the live viewing. We can even go down to 8 if necessary but we need to watch minimum 8 at once.

 

What would you recommend for an upload speed? I was thinking that a 2-5 mbps upload speed would suffice? Any and all suggestions are welcome!

 

Normally, the cameras will only be watched after work hours and weekends.

 

Thank you everyone.

I usually find that 1MBPS upstream will comfortably support

4 cameras, at sub stream speed producing fluid motion with minimal latency

 

I would agree that your estimate is as close as you can get without actually field testing.

i.e you see moving pictures without too much jerkyness and not too much delay

The 1mbps upload speed, is that on a DSL line, cable? t1?

 

What was the fps and bit rate set at?

 

Was this from exp since you are an installer?

 

Thanks for the advice!

I made a pointed comment to put you in the right direction,

I didn't offer to come round and do the job for you.
