An Uninterrupted Power Supply unit is a buffer between the AC supply outlet and the digital video recorder system. It is meant to protect your system from power surges, ‘brown out’ conditions and blackouts.

Depending on the size of system, it should provide power to the system for (X) amount of time. UPS units can be purchased at any office supply shop and should be recycled a minimum of every three (3) to (5) years. 

Digital Video Recorders are meant to be dedicated to recording video ONLY. Expect poor performance if you try to use the PC for other tasks.

HI DESERT ALARM will not support a PC that has new or downloaded software, Internet cookies and Internet history that is not meant to be used with the digital video recorder.

This depends on what type of system you purchased. Typically a 250GB system will retain up to two weeks of memory and a 500GB will retain up to approximately one month.

Absolutely nothing. Digital Video Recorder software comes with ‘FIFO’ (*First In-First Out) software programming. When PC hard-drives becomes full, it cycles and rewrites over the oldest video, thus history runs in a continuous loop.

Yes. Make sure to do this in a timely manner to prevent it from being overwritten.
