Question 1

What is an NVR camera?

Accepted Answer

An NVR camera is an IP camera that works with an NVR for cameras to capture, transmit, and store video footage over a network, offering reliable, high-quality surveillance with features like remote access, motion alerts, and centralised video management.

Question 2

Do NVR cameras work without the internet?

Accepted Answer

Yes, cameras with NVR can operate without an internet connection, as they can record and store footage locally on the NVR device. However, an internet connection is required for remote viewing, receiving software updates, and accessing the cameras from outside the local network.

Question 3

What are the 2 types of NVR?

Accepted Answer

The two main types of NVRs are PoE NVRs and non-PoE NVRs. PoE NVRs provide power and data through a single Ethernet cable, simplifying installation. Non-PoE NVRs require separate power for each camera, offering more flexibility in camera placement. The choice depends on your security setup needs.

Question 4

Are NVR cameras better than DVR?

Accepted Answer

NVR and DVR cameras each have their benefits, depending on what you need. NVR cameras generally offer higher video quality, better scalability, and advanced features like remote access and smart video analysis. However, DVR systems can be more affordable and easier to set up for smaller setups with analogue cameras. The choice between NVR and DVR largely depends on your security needs, budget, and the scale of your installation.

Question 5

Is NVR necessary for CCTV?

Accepted Answer

An NVR is not strictly required for CCTV systems, but it is necessary for IP-based setups. NVRs record and store footage from IP cameras, offering benefits like remote access, advanced features, and centralised management. For analogue CCTV systems, a DVR (Digital Video Recorder) is used instead.
