The use of Closed-circuit television (CCTV) has increasingly become a way of life. CCTV are video cameras that transmit a signal to a specific, limited set of monitors. It differs from broadcast television in that all components are directly linked, and that the signal is not immediately transmitted, although if desired, it may employ point to point wireless connections.

CCTV is often used for surveillance where there is an increased need for security, such as casinos, banks and transportation ports. They may also have military uses. The use of CCTV's in public places has increased, causing debt over security versus privacy. CCTV's can be permanently placed in service or only in service when required.

The federal government is spending an increasing amount of money on surveillance technology and programs at the expense of other projects. Washington DC is an example of this spending. The Metropolitan Police Department use of a Closed Circuit Television System (CCTV) for public surveillance has exceeded tens of millions in federal homeland security funds. The DC cameras are turned on during during major events and emergency situations, but after the bombings in London, DC Mayor Anthony Williams called for more federal funds to expand the use of camera surveillance systems.

Mayor Williams also proposed adding cameras to neighborhoods, parks, recreation centers and commercial areas throughout Washington DC. The use of Camera surveillance networks are growing in cities across the country, but statistics show that such systems have little effect on crime. Studies show that it is more effective to place officers on the streets than have them watching people on monitors. The (CCTV) public surveillance systems also raise privacy issues. Without tight legal controls on the use of camera surveillance systems, there are significant risks of misuse or abuse. Security cameras have long been an important tool in the law enforcement community. Eye witness testimony can be doubted and unreliable, but a picture does not lie. Retail establishments use security cameras to catch shoplifters and employee theft.

In recent years, red light cameras in heavily drug and crime areas have become increasingly common, freeing up police resources. It's not just stores and law enforcement that make use of security cameras. Security cameras are showing up in private residences all over the country. They have become more affordable, and able to be placed anywhere desired. There is a common delusion that security cameras are only for businesses or those with large homes. The truth is, every home is safer with security cameras on the promises. They are surprisingly affordable and simple to use. Security cameras of today are very user-friendly. You can install these cameras in a short time without hiring professionals.

Purchasing a security camera is more affordable than a home security system. It's a one-time cost with no need to subscribe to a monthly monitoring service. Security cameras connect to your home computer or DVR. You can connect to the Internet and view your property from anywhere you can access the internet. Also, you can set up your camera to send you an email or phone alert when motion is detected. Prices of security cameras are lower than ever.

If you do the correct research, even with a tight budget you can afford to install multiple cameras through your property. You can protect the front and back entrances of your property, as well as detached structures. You can view valuable property that is stored in such places as a storage shed, barn or garage. CCTV surveillance is here to stay and will continue to expand with technology and security.
