What is NVR in CCTV?

Installing a new CCTV system is a great decision. It’s an instant safeguard against theft and contributes to the protection of your properties from any number of potential risks and intrusions.

However, there are lots of different recorders on the market. If you haven’t used CCTV before, it can be challenging to determine which type of system would be best suited to your premises.

The Clearway team are experts in commercial CCTV installations, and always on hand to recommend the optimal solutions for you. In this article, we’ll explain the main types of recorder and where the differences lie.

What is an NVR CCTV Recorder?

NVR stands for Network Video Recorder. This type of system encodes and processes data captured by your CCTV cameras, and streams it to your NVR recorder.

You view the footage via the recorder, which is used for remote viewing and video storage.

Most high-performance CCTV systems use NVR recorders with IP (internet protocol) cameras. That means they can be used with wireless CCTV controls, viewed and managed on any remote device, and have a higher functionality level than a traditional analogue system.

The other primary type of recorder you might come across is a DVR CCTV system. DVR stands for Digital Video Recorder, and these installations process video data differently.

In this type of CCTV solution, the video is processed at the recorder itself. It isn’t compatible with IP cameras – DVRs are used with analogue cameras and apply to hard-wired CCTV systems without wireless functionality.

Is an NVR CCTV Recorder Better Than DVR?

A lot depends on when, where and how you wish to use your CCTV system. The key benefit of choosing a lower performance DVR recorder is that it is typically cheaper.

DVR recorders are much more straightforward but offer less flexibility, and generally can’t be combined with a range of camera types.

NVR CCTV recorders, on the other hand, offer far more advanced imagery and are versatile enough for use on a broad range of premises, properties and sites.

Benefits of choosing an NVR CCTV system include:

  • Higher performance technology with feature-rich CCTV solutions.
  • More robust cameras, since the data is processed at the camera rather than the recorder.
  • IP camera functionality, operating as standalone devices with chipsets that process high-quality surveillance.
  • These cameras can record audio alongside video footage.
  • More powerful hardware on IP cameras includes additional features such as the option to use facial recognition software and smart functionality.

For many sites, the reliability of their CCTV connection is crucial – the last thing you want is to install a surveillance system that fails to connect at the critical time.

DVR recorders are fitted with coaxial BNC cables, which have limitations in that there are two cables per device; one power, and one video cable. Therefore, your recorder must be close to a power outlet. These cables are also reasonably broad, and less appropriate for tight spaces, with little flexibility in the rigid casing.

Coax cables also don’t support sound, so are suited only to video-only CCTV captures.

NVR recorders work innovatively, with an Ethernet cable running between the camera and the recorder. Standard Ethernet cables are easier to route since they are slimmer with smaller connectors – and are therefore faster to install.

Ethernet cables are also cheaper, and widely produced, and so it is a lower-cost option should a cable require replacement or you decide to expand your system.

One of the significant benefits of an NVR CCTV recorder is that an Ethernet cable can transmit audio data natively; so you get high-quality video, accompanied by sound, which can be extremely useful.

Which CCTV Recorder Should I Choose – NVR or DVR?

For most modern businesses and homes, an NVR system is a preferable option.

They offer far greater flexibility and don’t necessarily require a direct physical connection between the camera and the recorder. IP cameras capture better quality footage and stream data to the recorder wirelessly, provided they are on the same network.

That means you can install multiple cameras, in different places, and even across various sites, all streaming CCTV captures back to the same NVR recorder.

While both NVR and DVR CCTV recorders are reliable, if you’re looking for better video quality, more reliable data transmission, faster installation, and wireless technology, your best bet is the NVR.

DVR systems are sufficient for straightforward security systems since they are generally cheaper.

This sort of CCTV recorder is ideal for properties already wired for coaxial cables – since this more complex installation often requires significant drilling and can take longer to install than an Ethernet cable for a contemporary NVR recorder.

A lot depends on your CCTV budget, what sort of footage you anticipate capturing, and whether wireless technology is crucial to your security strategy.
