CCTV cameras have been in use for many decades now, the idea has not changed much since their introduction. The two significant changes are their availability and their recording method. Most cameras today record the movie digitally, along with the details are held in digital form on the hard drive or other media. Using the raising popularity of such surveillance equipment, their price may be falling steadily, causing them to be available for small businesses in addition to citizens who want to protect their property and family.

When it concerns the principle popular features of CCTV security cameras.
Wireless vs. wired. Wireless cameras use radio signals to transmit the image for the main security board, and usually their very own built-in, rechargeable energy. They are an easy task to move, and is installed discreetly in places where installment of your wired camera can be unfeasible. Their price generally is a bit higher than of wired cameras though, as well as a wireless camera’s feed can easily be ‘hijacked’ and even modified by an experienced hacker from a distance. You ought to only install wireless cameras for short-term surveillance ( less than a year).
PZT. PZT is short for Panning, Zooming and Tilting. A PZT camera could be controlled by a staff, who can use it to follow a suspicious person, or simply scan a broader area. The professional is the fact that an enormous area can be surveyed by a single, well-placed PZT camera. The con is you need to have a person controlling it. Installing more static security camera systems is the perfect solution, but is more costly.
Dome cameras. Dome cameras are security camera systems in a very small semi-transparent hemisphere. The essential idea is that people can’t see in which the camera is pointed. It can be more discreet and contains a better retentive efficiency.
Color cameras. Some security camera systems record a colour film, that is useful when attempting to recognize a criminal. Yet, in another cases it’s pointless, as well as a color video uses up more space for storing. Color cameras are perfect for not security related uses, and value more than grayscale cameras.
