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. A quad is only needed 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 quad that we carry is high resolution real time quad that supports 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, video quality worsens the more ways you split a screen.
A quad is not needed when using a Digital Video Recorder because DVRs have a built-in quad.
