Sequential-switchers: do you need that sort of things? Well, it depends... If you plan to use only one camera for your Home Surveillance system then you need no Switcher at all. If you wish to place a number of cameras to perform your Home Surveillance from different points of view at the same time you could in principle dedicate a monitor and a video recorder to each one of the cameras. This does not seem to be a very practical solution, does it?
Short of that, to use only one monitor and one recorder you would have to provide a device that puts some order in that traffic of multiple video signals coming in from different cameras. Sequential Switchers, known also as Video Switchers, do just that. They are devices that allow the video signals from different cameras to be displayed on a single monitor and be recorded on a single video cassette recorder (VCR). This is done by connecting only one camera at a time to the peripherals (monitor and recorder) in succession. There is a loss of information known in advance in the use of Sequential-switchers. The point is that by programming with care the dwell time (the available ranges may be slightly different among various Sequential-switchers) during which each camera is connected and by showing all the views in automatic sequence, there is little chance that important information will be completely lost. Sequential-switchers are available for up to four or up to eight channels, each of which connectable to a different camera. The more cameras are connected, obviously the longer it takes to perform a complete sequence, so that the effective time for viewing the images of each one of the cameras is substantially reduced. There is therefore a trade-off to be considered. However, if necessary, the regular sequence of Sequential-switchers can be overridden by a signal generated by Motion Detectors (see Video Alarms) to switch on the camera where some action is going on, in preference to all other where the image remains still. Click on Sequential Switchers to see a few valuable offers. Sequential-switchers will serve equally well Black and White or Color Cameras, and are connected to a CCTV monitor, TV and/or VCR. Connectors are usually BNC jacks or RCA plugs. Normally the scene displayed on the monitor will rotate sequentially from one camera to the next.
The overriding or bypass feature of Sequential-switchers permits to select a single camera for continuous full screen monitoring. Some of the Sequential-switchers are supplied with a remote control to provide additional flexibility to the user. This inexpensive device is usually satisfactory when the Home Surveillance system includes more than a single camera. Looking for Sequential Switchers? Get low cost Security Systems quotes!
