Throughput / Processor Consumption For IP Cameras?

I know on the Bosch solutions you can access processor usage via telnet or in the topright corner of the cameras webpage it has a graphical indicator so you can see what happens when you turn on analytics or have multiple streams running out of it.

I do agree. Camera CPU overload is a reccurent issue, especially on entry level range of products. Camera sometime get saturated when generating 2 streams + motion detection ( MD is CPU killer)

Some Smart phones still using Mjpeg, requires that you generate a VGA Mjpeg in addition to your master HD, H264... double coding isn't also appreciated by entry level camera CPUS...

I have asked to some vendors to add a CPU indicator for installers to prevent them from too bad installations

Then the other point is that NVR/VMS get also saturated : one key stress test is to launch a Fast Speed Playback on 4 or 8 cameras...

If you imagine that normally , you are recording 4 Mb/s for 12 fps ( so 0,5 MB ) when you do fast speed you can have 60 fps/s , so 5 x 4 Mbs, and then 20 Mb/s multiplied by 8 cameras = 160 Mb/s during ...and your are supposed to keep on recording all your cameras (even motion detect is a 24/24 recording with auto delete if no alarm)

Most NVR are given for 60, 80 or 120 Mb/s ....so you can imagine.

This is calculated by using Port miroing feature on the managed switch to "see" (Wireshark / Networx..etc) what really happens on the input or output NVR port.
