Capture Error
Hi!
I've been getting a lot of those....
2019/08/06 19:51:52: Error performing motion capture for the camera "Piscine", motion capture mode has been disarmed. 5.0.1,5575,55340,818 Failed to record video frame. The key frame interval from the network device is too high, locate and change this setting in the device (may be called I-frame interval / I-frame rate / GOV length / Intra frame period).
What is the best way to correct this...
My I frame interval is at 50... BTW I don't know what I frame is for

We recommend an I-frame interval of around 2x the frame rate. So if your camera is streaming at 10fps, we recommend an I-frame interval of 20.
However some cameras have special codecs (e.g. Hikvision's "H.264+" or Axis' "Zipstream" technologies) that may result in very long I-frame intervals, so please check for this and turn any such features off in the camera's settings. You should be using standard H.264 or H.265 with a fixed I-frame interval.
This is the thing I came here for...

Vivotek cameras offer:
I feel like 20 fps and 1 S seem like a good combination for our ~45 cameras.
Am I on the right track there?
Hi @YesThatAllen 1s is fine for the intra frame period, although 2s is generally better (you'll get a bit more of a bandwidth-efficient stream).
20fps is a high frame rate for general-purpose CCTV. This would be fine if there are no significant resource or storage limitations, and you like the added smoothness of the video. But if you need to lighten the processing load and/or reduce your storage requirements, you could use something like 10fps instead, which is perfectly adequate in most cases.
