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. As always if you have any questions about this or any other product please don't hesitate to email your questions or concerns to info@nannycamsetc.com and we will be happy to assist you.
