Wireless surveillance cameras help you to monitor your home from virtually anywhere.

Closed-circuit television, also known as CCTV, is one of the most commonly used surveillance cameras on the market today. It works by sending signals over a small area using video cameras. By using point-to-point wireless links, the user can send the signal to any monitor he wants. There are CCTV systems in tons of different locations, including banks, airports, and even in the mall and different kinds of stores. It can also be used in industries when the performance of a specific machine needs to be constantly monitored to make sure it is doing its job correctly. Unlike the old CCTV systems, today's modern technology allows CCTV to use high-definition cameras that can be viewed through a computer, allowing for the tracking of objects. Using a computer, CCTV cameras can be programmed to track the exact movements of a certain object in whatever environment you are surveilling.

This can also be accomplished by using GPS-enabled security cameras. This type of system can track an object or an individual over extreme distances. Some security cameras will even come with the GPS chip embedded within the system, this allows for every picture taken to be geotagged. Using these tags, a person can trace the exact location of the person or object using the cameras, mapping tools, and the internet.
