These may include places such as banks, casinos, airports, military installations, and convenience stores that require regular monitoring. CCTV consists of a system of cameras that continuously monitor and record footage for viewing on a close circuit television.
The footage can be viewed later and can be used as legal evidence if need be. The most convenient thing about CCTV security system is that the user can view the recorded footage anywhere, including office, home, or somewhere else without being present on site. Arrangement can even be made for live feeds to be watched real-time through Internet. CCTV systems can also be used to protect your home, inside and out. From wireless systems that dont require breaking walls to run cables to integrated systems that work with your intercom or alarm systems, one can choose from various options available. With CCTV systems you can be sure that your house is safe from unwanted visitors and criminals. With time, CCTV security systems have become more sophisticated and easy to use.
The latest technology allows you to watch live or recorded images from surveillance cameras onto your monitor, or even a regular TV. The cameras installed at different vantage points are sensitive enough to capture even slightest of movement. There are cameras that work even in dark to keep your home and office premises safe during nights also. They make use of red infra light to detect and capture movements.
Nowadays most CCTV systems make use of Digital Video Recorders (DVRs) that are programmed to record data for many years. They offer a range of quality and performance options to the users for enhanced functioning. These features may include motion-detection and email alerts among others. Among the latest development in the filed of CCTV systems are decentralized IP-based CCTV cameras. These cameras come equipped with megapixel sensors and they are capable of completely stand-alone operation through direct record of footage to network-attached storage devices, or internal flash.
