A quad is an accessory to your surveillance system that splits a video monitor into 4 screens. Without a quad you would only be able view one camera at a time.

The quads that we carry are high resolution real time quads that support up to 4 cameras. You also have the ability to playback and zoom in on recorded video.

A quad is not needed when using a Digital Video Recorder because DVRs have a built-in quad.
