Quads

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. You would only need to use a quad when you are using more than one camera and using a VCR or VISEC to record or when you are only monitoring and not recording at all. The quads that we carry are superior quality high resolution real time quads that support up to 4 cameras. You also have the ability to playback and zoom in on recorded video.

There are other products out there that can split a screen more than four ways. However, the quality of thevideo worsens the more ways you split a screen.

A quad is not needed when using a DVR to record because DVRs have a built-in quad.
