DVR

A Digital Video Recorder or DVR is the key component in CCTV security systems. With a DVR, you can not only record and view each of your CCTV cameras simultaneously, but you can also take advantage of several features such as smart search, remote viewing capability, archiving, motion detection, privacy masks, and email notification alerts, among many others. Most models boast H.264 video compression technology to reduce the storage size required.Analog Cameras
