Which two critical requirements must be addressed in the RF site survey for wireless video surveillance? (Choose two.)
The correct answer is A. packet loss B. jitter. Wireless video surveillance is a real-time, continuous media application with two non-negotiable RF quality requirements: (A) Packet loss - even small amounts of packet loss cause visual artifacts, frame freezing, or complete stream interruption in video feeds.

Explanation
Wireless video surveillance is a real-time, continuous media application with two non-negotiable RF quality requirements: (A) Packet loss - even small amounts of packet loss cause visual artifacts, frame freezing, or complete stream interruption in video feeds. RF retransmissions increase latency and surveillance gaps. (B) Jitter - irregular packet inter-arrival times disrupt the real-time decode pipeline of video codecs, causing stuttering and buffering. The site survey must confirm the RF environment can sustain low packet loss and low jitter across all camera locations. Bandwidth (C) is important but secondary once loss and jitter are controlled. Channel selection (D) and WLC configuration (E) are implementation concerns, not primary site survey deliverables measured at the RF layer.
