When designing your own digital video security camera system, whether it is for residential or commercial use, it is important to make the right choice for the stand alone DVR for security camera. A stand alone DVR or Digital Video Recorder is basically the “brain” of the system that coordinates the functions of the component parts and provides for storage of the digital video files.

A stand alone DVR for security camera is preferable because it is a self-supportive unit that does not rely on any other additional component (such as a personal computer) and does not require an internet connection. A typical stand alone digital video security system contains one or more digital video cameras, the DVR with a Digital Signal Processor or DSP, and a monitor.
