Dahua PTZ Camera SD59225U-HNI Network Bandwidth Requirements

[Ratfink11]

Hi All,

I was hoping someone could check my math for bandwidth requirements for my dahua ptz cameras SD59225U-HNI.

From what I can figure for the highest resolution running H264 at 50fps requires on the high side 8 Mbps per camera.

Does this sound right for a 2MP camera?

I've got 4 runs of close to 700 feet. These long runs will have a 3 camera cluster every 300 feet roughly. Im right at the limit of Cat5, I figure roughly 48Mbps for 6 cameras with 2 switches 1 for each group of 3 cameras.

Or I could do it the right way and run fiber to ethernet converter switch.

Thoughts or suggestions?

Thanks
R

Your math is spot on.

Ok... So I think I will try it... A single cat5 cable run 300 feet connected to 3 cameras and a switch, then another 300 feet to 3 cameras and a switch, then last 300 feet to last 3 cameras and a switch. Essentially daisey chained with a switch & cams every 300 feet. I wish I could find an example install like this.
