Multicast

Answer

Broadcast

Answer

Unicast

Answer

VPN Tunnel

Question 3

When comparing the H.264 and H.265 (HEVC) video compression standards, what is the primary advantage of using H.265 for a new IP surveillance system?

Accepted Answer

Approximately 50% reduction in bandwidth and storage requirements for the same video quality.

Answer

Wider compatibility with older VMS and NVR systems.

Answer

Significantly lower processing power required for decoding.

Answer

Lower latency for real-time video streaming applications.

Changing all default usernames and passwords.

Answer

Enabling motion detection alerts.

Answer

Configuring the highest possible frame rate.

Answer

Placing the cameras on a public-facing Wi-Fi network.

Question 5

A camera is installed at a remote construction site with an unreliable and low-bandwidth internet connection. To ensure that high-quality video is always recorded even during network outages, which feature is most essential for the camera to have?

Accepted Answer

Edge storage capability (e.g., an SD card slot)

Answer

Cloud storage integration

Answer

H.264 compression

Answer

Wide Dynamic Range (WDR)

Question 6

Which of the following protocols is primarily a 'network remote control' used to establish, manage, and terminate media sessions for IP cameras, often working in conjunction with RTP to transport the actual video data?

Accepted Answer
