  1. Latency:
    - for live video no more than 10 seconds. If this value is exceeded, the connection to the IP device will be terminated.;
    - for face recognition no more than 1500 milliseconds, if this value is exceeded, many faces will be missed due to the skipping of a large number of frames.;
    - for service and smart detection tools no more than 400 milliseconds, if this value is exceeded, the quality of object detection will decrease, smart detection tools may incorrectly generate alarms.


  2. Packet loss:
    - for live video no more than 40%. If this value is exceeded, the connection to the camera will be terminated. With a packet loss of 10% to 40%, frame drops will be observed (the more losses, the more drops).;
    - for face recognition, service and smart detection tools no more than 25%. If this value is exceeded, skipping of faces will be missed, and the tracks of smart detection tools will not correspond to objects.
