Digital Video Recorders (DVR’s) allow continuous digital recording for days and weeks at a time. Unlike tape based systems the footage is always high quality no matter how many times you record over existing footage. DVR’s also have built in multiplexing allowing split screen monitoring/recording without having to add an additional unit.


What is a Digital Video Recorder?

A Digital Video Recorder (DVR) simply is a computer hard drive with functionality and connections that are designed for the CCTV Security market.


What are the advantages of a DVR?

Before DVR’s existed the most common way of recording CCTV video footage was through a multiplexer and time-lapse VCR’s. However, DVR’s have many advantages over the multiplexer and VCR Combo:

• DVR’s can have a huge storage capacity and so eliminate the need to frequently change tapes
• DVR’s don't have problems with tape or VCR’s wearing out and so consistently produce higher quality recorded images
• Because DVR’s record digitally, you can retrieve recorded footage instantly rather than scanning through hours of video tape
• Some DVR’s have motion detection software built-in, removing the need for separate PIR's (passive infra-red detectors)
• Some DVR’s can be viewed over a network or the Internet allowing them to be used for remote viewing
• DVR’s often work out cheaper than the combined price of a time-lapse VCR, video tapes and a multiplexer
