What is a DVR system?

DVR stands for Digital Video Recorders. They allow you to record security footage that your CCTV security camera captures, allowing you to watch it back when you need to. This is paramount to site security. In the case of a security threat or criminal attack, a DVR system will ensure you’ve got security footage as proof, and it will also enable you to identify the assailant. In fact, businesses of all sizes should make a habit of regularly backing up their data, as it safeguards you in the event of physical damage or theft.

DVR systems available today tend to be capable of recording footage from up to 16 CCTV security cameras all at once – known as ‘multi-channel recording’. DVRs also tend to come with hard drives that enable you to store and back up the footage that has been recorded. Alternatively, more advanced DVR products will support cloud storage, or even come with apps that help you monitor live streams when you’re away from your site.

What is the difference between a DVR and a NVR?

While DVR stands for Digital Video Recorder, NVR stands for Network Video Recorder. NVRs use IP cameras which are technologically advanced and have the power to actually record and store video footage on their own – with the help of an internet connection. DVR systems, on the other hand, use analogue cameras. These cameras are unable to store and record CCTV footage themselves. They send unprocessed streamed footage through coaxial cables to a DVR – which then processes the video.

In technical terms: “A DVR encodes and stores video signals, while an NVR stores video that a camera encodes.”
