Should you need to use hidden digital video recorders, and you need to have more than one, then you definitely want to consider using a quad all-in-one system. These hidden digital video recorders are great because not only can you operate multiple cameras, you can control them all from one sleek, compact unit. The multiplexer and the recorder are combined, so it does not matter where you place it. These wonderful hidden digital video recorders have no tapes to worry about; you can set it up and forget it until you want to review a video. There is no replacing worn out old tapes, no rewinding, no fuss, no muss, and that means no down time, and more importantly, no leaving your place unprotected while it is out for maintenance. Because it is a quad switcher, you can view all four cameras at the same time on one screen. This system also allows you to set your hidden digital video recorders for continuous recording over a twenty-four hour period, or you can set it to be alarm activated, so that the cameras only switch on when an alarm is sounded. This feature will extend the over all recording time.

Plus one of the most beautiful things about this system is that you can record and playback simultaneously.

No need to stop recording just to access previously recorded material, and the handy search functions allow you to do frame-by-frame viewing, view the alarm events or you can use fast playback. And you can record as slow as one frame every ten seconds or a fast as fifteen frames per second.
