Quad processors can be used to connect four analogue cameras to a single video input. They work by combining the video from four cameras into one analogue output, which is split into quarters. SecuritySpy can be set to treat this as four independent cameras. However, we do not recommend the use of quad processors in most circumstances because they halve the resolution of the video from each camera. Quad processors cannot be used in conjunction with network video servers.
