Colored "blocks" on H264 video
Hi,
I use the AVTECH 552 with Security spy in the 1080p H264 mode. When it gets dark the camera switches automatically to IR, but at the same time the H264 video stream starts to show colored blocks. Unfortunately, I only found a manual way to fix this by unticking the camera enabled box in camera settings pressing "OK" and the ticking camera enabled again in camera settings (i.e. disconnecting from the camera and re-connecting). The recording of the stream shows the same colored blocks and in addition, the recording seems to be static, i.e. it is a video where all frames are the same still image from the time the colored blocks started to appear.
Any idea how to avoid this?

I can check the JPEG specs tonight.
What I did already yesterday was storing the movie "without re-compression". When I check these movies with a tool to show the specs of the video stream, I get the following:
Daylight Video: H.264, 1920 × 1080, 25 fps, 4.81 Mbps
Night Video: H.264, 1920 × 1080, 25 fps, 10.29 Mbps
So it seems that the main difference between day and night is the data rate (I think due to the much higher noise level in the night movie). Perhaps this is the cause of the issue? But I do not know how to fix that.
I checked the JPEGS as you suggested. All are 1080p.
