Closed Circuit TV (CCTV)
Statistics point to major reductions in the amount of crime being committed where CCTV cameras are installed. These statistics have shown that simply installing a CCTV system can reduce crime in the areas covered by that system by over 90%. As businesses and building owners confirm that they are having similar results in many different type of businesses you will appreciate why CCTV is seen by many as the best system for deterrent and detection and is a sound investment in property and employee protection.
Generally, once a visible camera system is installed only fools will attempt to perpetrate offences within it’s field of view. Perpetrators are often recognized and caught as a result of the images captured by a suitable system.
Other uses of closed circuit TV systems may be production control in factories, warehouse and building security, asset control, a deterrent to fraudulent public liability claims, traffic monitoring, medical applications, teaching applications, observation of hazardous areas, environmental observation etc… Low voltage systems are also available for installation in trucks, buses and earth moving equipment. This is for safety when manoeuvring, allowing the driver to see any dangers which may be previously out of sight.
There are several types of zoom or wide angle cameras and lenses to choose from. Cameras now come in every shape and size allowing you to be only as conspicuous as you need to be.
For a closed circuit TV system to work effectively cameras, lenses, housings, multiplexers, cabling and image storage devices must all be matched to achieve the desired resultant picture quality, size and frame rate.
Digital Video Recording Systems
Advantages of digital video recording and image storage attached to a CCTV system compared to the older style VCR tape include:
Any video surveillance can be monitored and/or recorded to either VCR tape or digital storage for a visual record. These images may be stored for future reference. Camera systems provide a deterrent to pilferage/ unauthorized access and can also provide visual evidence for public liability or worker compensation disputes.
