Contact SupplierCCTV is a visual surveillance technology designed for monitoring a variety of environments and activities all at the same time. CCTV systems typically involve a dedicated communications link between cameras in the field and monitors at one or more control centers. Systems can be made up of technically mature analog cameras and image storage devices, or newly developed digital cameras and image storage devices, or a mix of the two technologies.
CCTV systems may provide real-time, time-lapse, event, or digitally recorded surveillance information to help in detecting, responding to, investigating and providing evidence for security, safety and related incidents. A CCTV system may also be used to prevent security breaches by allowing security personnel to monitor access control systems at entry points to secure areas.
FEATURE
View free video is accomplished through recording “events” versus continuous recording of empty areas. Event recording is accomplished through various forms of ‘alarm interfacing’. I.e.; A magnetic switch may be added to a door to trigger the camera’s assigned recording device to record the image from the camera in the ‘event’ that the door is opened. This saves video storage room (tape, disc, or hard-drive) as well as precious time reviewing video information.
Hands free video systems are also accomplished through the use of various types of electronic, programmable triggers. I.e.; the door opened, the video recorder started recording automatically and continued until the door closed. This action frees the guard from being needed to control the function of the system versus responding to the situation.
Many systems today have the ability to be ‘pre-positioned programmed’. This gives the designer or operator the ability to set up multiple view points in advance of need. In this way, cameras on pan/tilt systems (either mechanical or digital) can be programmed to automatically move from point to point in a pre-determined route. Additionally, alarm points (such as the door in the previous paragraph) can be added to automatically move the camera’s view to the alarmed position when needed. Once again the operator is freed up to respond to versus operate the system..
