Citiguard Protection Service outline the applications of closed circuit televisions

Supplier News

Closed circuit TV (CCTV) systems have been available for many years. They have also undergone some transformations in recent years. What used to be expensive, cumbersome and hard to configure systems are now reasonable, easy to configure, easy to maintain and provide more versatility and usefulness than a few years ago. Citiguard Protection Service discuss the various applications of closed circuit televisions.

The primary uses for CCTV systems are surveillance, traffic control, theft, shoplifting, employee theft, and/or robbery deterrence and identification. Surveillance and traffic control probably do not require colour cameras and black and white may provide better resolution. However, theft, shoplifting and/or robbery deterrence and identification may require colour cameras; if there is an arrest and prosecution, a court will require colour to make positive identification; on a black and white recording, a red sweatshirt would appear to be grey.

Factors such as lighting conditions, indoor and outdoor, viewing angle will help in choosing the right kind of camera and lens combination, correct mounting or enclosure and cabling needs. Deciding how one will view, record and store the information is next on the list.

The choices for viewing include a central monitoring point, multiple monitors and single monitors that can show multiple images on the computer through the internet. Recording and storing information can range from a time lapse recorder, computer or a DVR recorder. If individuals use a time lapse recorder, they need to be aware of the limitations on what is recorded and when, and they may need more equipment, such as a switcher and/or multiplexer.

Storage of video tapes can also be a challenge. With a DVR recorder, all users need to decide is how long they want to save events at one time; for longer the time frame, the bigger the hard drive is needed. Events or time periods that need to be saved can be downloaded to a computer, or burned to a CD, making it economical and easy to manage.

A DVR, unlike the time lapse recorder, will record continuously from all cameras. They also incorporate the switcher and multiplexer functions into one unit. A few years ago, DVR recorders were expensive, but today they are reasonable and will continue to go down in cost and provide more advanced features.

When individuals are ready to specify their systems, they can contact their local CCTV expert for the latest information and a competitive quote. These professionals have access to all the new products, and know how they work and what works in any given situation.

Some businesses will display a fake camera in their place of business with the idea that this will deter shoplifting, robbery or employee theft. In light of some recent court case, this practice should be discouraged. It is argued that the presence of a ’dummy’ camera can provide patrons or employees with a false sense of security that is not there. This false sense of security has led to injury.

Buying security system, as an all in one set from a ’big box store’, can save some money. However, individuals will end up with equipment that is inferior and not specified correctly for their needs and when they need service or adjustment, they may not be able to get service.
