In some cases, one security camera is not enough. This usually includes any business building with multiple entrances/exits and many shadowed areas, but even large houses with multiple areas for sneaking up on can benefit from having a number of cameras installed. You could monitor each of these cameras separately, but that just makes things more difficult for you, and easier for the intruders you’re trying to guard against. In the movies, you’ve probably seen security guards sitting in front of monitors with four or more camera outputs on them. This 4-in-1 effect is achieved with the use of quadsvideo processors that display real-time images from four different CCTV cameras.Most quad systems can be easily hooked up to a DVR or VCR for recording. This gives you just as much control as you would have over an individual camera, but with the benefit of being able to monitor multiple locations at once. It also means you don’t have to spend your days in front of the camera, but can always go back to a particular time period if necessary, as long as it’s been stored. The time, date, and camera title will be displayed for each camera, so you can quickly find the one you need.On advanced quad systems, you can set alarms to go off whenever security is threatened, such as if motion is detected in a restricted area. Other features that you may find on modern quads include a 30 fields/second real-time refresh rate, adjustable gain control for each camera, and automatic sequential switching, with customizable dwell and selection options. Take control of your home or business’s surroundings with a high-resolution digital quad, and you’ll be able to literally see your security grow.
