DVR's (Digital Video Recorder) have been around for years in legacy coaxial systems. A DVR is the head unit of the operation, all of the cameras connect directly to the DVR using RG59 wire. In modern times the DVR has had to evolve to keep up with the requirements of high-definition.
The DVR's in this section are all high definition systems, they support HD over-coax cameras, older legacy cameras along with even IP cameras. This makes them the perfect choice for upgrading an existing system since they will work with such a large variety of different types of cams. A lot of our customers will replace the DVR and a few crucial CCTV Cams with HD versions and leave the rest since you can mix and match the new and old with these recording systems.
Just because theses systems are compatible with older cameras doesn't mean they lack in features. These systems can record up to 5MP resolution, can do motion based recording and have the ability to be remotely viewed from your computer, smart phone and tablets.
