A digital video recorder (DVR) system is a type of CCTV security system. The name refers to the fact that all of the footage that is recorded from the cameras is stored digitally, not physically on tapes or cassettes. Cameras are connected to the system via a coaxial cable (which is also referred to as an analog connection). This differs from other methods, for example, NVR systems are connected via Ethernet cables. Footage from a DVR system is stored on a hard drive (HDD). The system is comprised of a number of cameras that are all connected to the DVR device or a different computer, depending on the type of system that is being used. Analog cameras must be connected directly to the DVR, they cannot connect to a computer. Hybrid systems such as an XVR (a combination of DVR + NVR technology) allow cameras to connect to computers. Most DVRs offer up to 16 channels, but on the market you can find systems with 32 separate channels, providing users with full coverage of an area. An identifying feature of DVR systems is the fact that they are closed circuit, and do not connect to any networks. For many older DVR systems they cannot be accessed wirelessly by mobile devices, however, newer models can provide mobile access. The system can be controlled using the software in the form of an app, and users can also check stored footage this way. Explore Full Analog CCTV Kits that come with a DVR.
