B frames active
The camera is sending the video stream with B frames.
Encoding on the camera and decoding on the recorder require more time (min. 120 ms).
This results in an addition delay. But the video quality (depending on the bit rate) can be
increased in some cases.
B frames inactive
The camera is sending the video stream without B frames.
Encoding on the camera and decoding on the recorder do not result in an additional delay.
But the video quality (depending on the bit rate) can be reduced in some cases.
