Quad Processor is a video switching device that accepts video input from four cameras and converts them to all display on one monitor and / or video recorder. When using multiple cameras, quads and multiplexers help to cut down on the amount of additional equipment needed for a dedicated surveillance system. However, DVR digital video recorders with multiple video inputs are quickly replacing quads and multiplexers. DVRs are now capable of doing what required a processor and VCR in the past (plus a whole lot more).
Quality Differences there are literally hundreds of different cameras available in the CCTV industry which on the outside appear very similar or identical to those offered at Eyespyvideo.com. However, inside these cameras (the crucial part) are so many different image sensors, each with different levels of performance, that it becomes quite confusing to even the experienced camera shopper. Beyond inspecting technical specifications and even the advertised CCD manufacturer, it is also important to test for actual real world performance. We thoroughly examine each part we stock (as well as many others which do not make the cut) to ensure their high tvres and performance under a variety of conditions. Eyespyvideo.com is proud to carry only the finest quality CCTV surveillance equipment available on the market today.
