    CCTV video cameras are cameras that require a movie and forward it to some central security board (often a computer) over a closed circuit, inaccessible from the public. CCTV cameras come in use for a number of decades now, but the idea hasn’t changed much since their introduction. Both the significant changes are their availability as well as their recording method. Most cameras today record the video digitally, as well as the data is stored in digital form on a hard disk drive or another media. Together with the raising popularity of such surveillance equipment, their price has been falling steadily, causing them to be designed for small businesses proprietors in addition to citizens who wish to protect their house and family. This post is written for many who usually do not yet have knowledge and experience about video security cameras.

    Let’s talk about the main options that come with CCTV video security cameras.

    Wireless vs. wired. Wireless cameras use radio signals for you picture towards the main security board, in most cases have their own built-in, rechargeable power. They may be simple to move, and can be installed discreetly in places where installment of a wired camera could be unfeasible. Their price can be quite a bit higher than of wired cameras though, and a wireless camera’s feed can be simply ‘hijacked’ or perhaps modified by a professional hacker from your distance. You ought to only install wireless cameras for short-term surveillance ( under a year).

    PZT. PZT is short for Panning, Zooming and Tilting. A PZT camera may be controlled by a staff member, who is able to put it to use to adhere to a suspicious person, or just scan a broader area. The professional is a huge area may be surveyed with a single, well-placed PZT camera. The con is you need a person controlling it. Installing more static video security cameras is a better solution, but will cost you more.

    Dome cameras. Dome cameras are video security cameras in the small semi-transparent hemisphere. The essential idea is the fact that people can’t see in which the camera is pointed. It is more discreet and possesses an increased retentive efficiency.

    Color cameras. Some security cameras record a color video, that’s useful when trying to identify a criminal. However in some other cases it’s pointless, and a color video consumes more space for storing. Color cameras are ideal for not security related uses, and price more than monochrome cameras.
