Securing your property is one of the growing domestic issues in San Francisco, CA today. Some research suggests that at least one home is broken into every minute. Therefore, protecting homes and properties has become a priority and the advent of Closed Circuit Televisions or CCTVs is timely to say the least and can be employed for this purpose.

What is CCTV exactly? CCTV is a surveillance technology used initially to monitor commercial properties and public places, but has been adapted to the residential property to help home security. It is basically a camera, or a network of linked cameras, that produce viewable and recordable images. It would be quite unusual for a comprehensive security system to be without CCTV. The cameras can interface with other systems such as alarms i.e. the cameras can start recording when an alarm is triggered either automatically or by human intervention. Nowadays, wireless CCTVs systems are most popular as they obviously do away with wiring systems and they are also easier to operate and maintain. They are also easier to protect from being compromised. The wireless cameras also allow for more flexibility and mobility, as it is much easier to install wireless cameras, even in the most inaccessible areas.

Another important development is that CCTV also facilitates remote monitoring i.e. you do not have to be on site to view the images. So it is possible to view real time images of what is happening back home from your work place or on holiday, you need to type in the URL of the server that controls the wireless cameras from any browser. You can see these images just as easily on your mobile phone. Some security companies will also provide a service that monitors the premises for you, so you effectively are renting the equipment. That way you can keep up with any major technical advances.

Speaking of advances in technology, CCTVs now provide a new level of sophistication, such as infrared night vision. The ability to monitor in the dark is obviously fundamental to a comprehensive home security system. Another development is the Passive Infrared motion detection facilities and Pan Tilt Zoom cameras. These cameras are able to rotate horizontally through 360 degrees, vertically through 900 and have zoom lenses capable of giving more than ten times the current optical zoom.

Adding a further level of security are the covert CCTV cameras available in the market. Also known as miniature cameras, these CCTV cameras are very small or easy to disguise thus enabling so called covert surveillance. Normal CCTV cameras still prove effective, but are vulnerable to tampering and damage by any would be offender. These hidden or mini CCTVs offer an extra level of security to your property in San Francisco, CA.

Apart from the obvious merit of monitoring your home and valuables while away from your home, CCTV Images have also been used as evidence and so offer a greater chance of catching the culprit should any offense take place. These cameras provide the visual evidence of the offender’s crimes. Once people know they have been videotaped there is little, they admit to the offense immediately. Such benefits, advance technology and easy availability make CCTVs the most widely used and relied upon security measure used in not only homes but also banks, offices, hospitals and other commercial enterprises.
