A Short Guide To Choosing Surveillance Camera Systems:

How important are surveillance camera systems? For one, surveillance camera systems are a good way to prevent theft and burglaries. In many stores, for example, theft and shoplifting attempts are significantly reduced when surveillance cameras are prominently displayed. Surveillance camera systems have also been effective in helping monitor and track events in real time. They also make it possible to go back to certain times or days that were already recorded to check for certain activities.

In order to maximize the use of surveillance camera systems, it's important to choose the right type and combination. Here's how:

Buying a surveillance camera system A standard surveillance camera system consists of three major components: the camera, the monitor and the recorder, all of which are connected by cabling. Of these, the surveillance camera is probably the most common part of the system, often appearing ubiquitously in homes, stores, banks and office buildings.

For a simple surveillance camera system, a basic single camera system will do. This is usually composed of a camera transmitter that feeds images or pictures to a monitor receiver. For purposes of keeping a documentation of an event or activity, a recorder may also be used. For most home owners, a basic system such as this single-camera and monitor device usually suffices.

However, there are surveillance camera systems that include multiple cameras to provide more areas of coverage. From 4-camera systems to 16-camera systems to surveillance systems composed of dozens or hundreds of cameras, surveillance camera systems may be as simple or as complex as the needs of home or business owners.

When considering which surveillance camera system to buy, determine the size of the area you want to observe and how many cameras it might take to provide effective coverage. If you foresee an expansion in the future, you might want to consider buying a system that can accommodate additional units and accessories.

Go wireless or hardwired? The location of the area where you wish to install a surveillance camera system should also figure into your decision. Oftentimes, an area will determine whether or not you need to use a wireless or a hardwired system. Hardwired systems, for example, take a lot of planning and installation skills to put up. They also cost more than wireless systems. However, they do provide reliable broadcast and transmission.

Wireless systems offer more flexibility, allowing you to place cameras in locations that you like, without worrying about wirings and electrical outlets. They're also a lot more cost effective than wired surveillance systems. However, when using a wireless system, there is a need to be careful about placement, too. Wireless systems are often subject to electrical interference, such as those coming from wireless telephones, airconditioning and other appliances.

Recording images The function of most surveillance camera systems extends beyond just plain monitoring to include image recording. Cheaper systems often use VCR-based recorders, keeping images stored in videotapes. Better units even use motion-activated sensors that will only begin recording images if triggered by movement.

A newer recorder system utilizing digital video recording or DVRs, provide more efficient recording capabilities. Digitally-captured images are also a lot easier to store and retrieve for future reference.

How about audio? Some surveillance camera systems come equipped with audio capability. If you need to completely document events, a system that is capable of recording audio can offer complete documentation. The only drawback is that surveillance camera systems with audio are quite expensive. However, they do offer a good, solid source of evidence just in case.
