Security is hugely important for businesses and residential properties and one of the best forms of security is CCTV cameras. However, they aren’t much use without something to record the images onto and for this purpose, you need a good quality CCTV digital video recorder (DVR).

A CCTV Digital Video Recorder (DVR for short), is essentially a computer that saves an incoming (analog) security video image, converts it to digital, compresses it and then stores it to a hard drive.

Multiple cameras can be connected to a single DVR, usually with a choice of 4, 8, 16, or 32 camera inputs. Your digital video recorder (DVR) will then enable you to view all of the images at once, or one at a time if you prefer. All of the images will be converted, compressed and saved onto the hard drive.

DVR’s are available with 1, 4, 8, 9 and 16 channels. The channel basically serves as a video feed.

To sum up, a DVR is the smart technology that captures the images and saves them onto the hard drive. They are a lot more flexible than the old VCR’s that required VHS tapes, providing more storage capacity based on the size of the hard drive. You have the ability to search through the recordings by date, time or incident and as the recording is digital, there will be no loss of quality or signal.
