CCTV CCTV Network & IP Camera Configuration 2

Question 1

What is the maximum recommended cable run for standard Cat6 Ethernet cable in a CCTV installation?

Accepted Answer

100 meters (328 feet)

Answer

The IEEE 802.3 standard limits Cat6 Ethernet runs to 100 meters to ensure signal integrity and reliable PoE delivery to IP cameras.

Question 2

What is the key function of a Network Video Recorder (NVR) in an IP CCTV system?

Accepted Answer

To receive, decode, and store video streams from IP cameras over the network

Answer

An NVR connects to IP cameras over the network, pulls their streams, and stores the video to hard drives for later retrieval and review.

Question 3

Which encryption protocol is recommended for securing IP camera web interfaces and remote access?

Accepted Answer

HTTPS (TLS/SSL)

Answer

HTTPS with TLS/SSL encryption protects login credentials and video streams from interception during remote access to IP cameras and NVRs.

Question 4

What is port forwarding used for in a remote CCTV viewing setup?

Accepted Answer

To route external internet traffic to the NVR inside the local network

Answer

Port forwarding on a router directs incoming internet requests on a specific port to the NVR's local IP address, enabling remote viewing from outside the network.

Question 5

What does Quality of Service (QoS) accomplish in a CCTV network?

Accepted Answer

Prioritizes camera video traffic to prevent buffering and dropped frames

Answer

QoS settings on network switches and routers give CCTV traffic higher priority over less time-sensitive data, ensuring smooth video streams during peak network usage.
