Bit rate / Video quality: Select the maximum bit rate (h.264) or video quality
(MJPEG) from the drop-down menu. The recommended
settings for h.264 are 4 mbit/s at 1080p and 2 mbit/s at 720p.
QP:
Setting the size of the I-frame image. Higher values (eg +12)
result in better image quality, however, there may be
restrictions on playback, since the decoding is more complex
and takes longer.
GOP Size:
Frequency, how often an I-frame image is transferred. At
higher frequency the Bildqualiät is better, however, increases
the bit rate required.
10.4.1.7 Network loss recording
This function allows you to record video data to your internal camera memory in case of IP
network failure. Despite the recording device losing its connection to the network, the video data
remains available in the camera for this period.
As the function tests the existence of a certain IP address or domain address in the network, it
can also be considered "recording when the network device fails". That means that the camera
can record internally if another camera fails. This function is useful where both cameras have the
same or a similar field of view.
Enable network loss recording:
activates the function
Cycle recording: if activated, old data is deleted when the internal memory
reaches its maximum capacity so that new data can be
stored.
