CCTV security cameras are cameras that have a video and forward it into a central security board (normally a computer) with a closed circuit, inaccessible with the public. CCTV cameras have been around in use for many decades now, however the idea has not yet changed much since their introduction. The 2 significant changes are their availability as well as their recording method. Most cameras today record the movie digitally, and also the details are kept in digital form on the hard drive or any other media. With the raising popularity of such surveillance equipment, their price has been falling steadily, which makes them available for small business owners as well as citizens which protect their home and family. Advantages and drawbacks written for those who usually do not yet have knowledge and experience about security camera systems.
Let’s talk about the key features of CCTV security camera systems.
Wireless vs. wired. Wireless cameras use radio signals for you the picture to the main security board, and in most cases have their own built-in, rechargeable power source. They may be simple to move, and is installed discreetly in places where installment of a wired camera will be unfeasible. Their price generally is a bit higher than of wired cameras though, along with a wireless camera’s feed can be ‘hijacked’ as well as modified by a skilled hacker from a distance. You should only install wireless cameras for short-term surveillance ( under a year).
PZT. PZT stands for Panning, Zooming and Tilting. A PZT camera can be controlled by a worker, who are able to use it to follow along with a suspicious person, or simply scan a broader area. The professional is always that an enormous area could be surveyed with a single, well-placed PZT camera. The con is basically that you need to have a person controlling it. Installing more static security camera systems is the perfect solution, but will cost you more.
Dome cameras. Dome cameras are video security cameras inside a small semi-transparent hemisphere. The fundamental idea is the fact that people can’t see in which the camera is pointed. It can be more discreet and has a better retentive efficiency.
Color cameras. Some security cameras record a color video, which can be useful when trying to distinguish a criminal. However in some other cases it’s pointless, along with a color video occupies more storage space. Color cameras are ideal for not security related uses, and value greater than white and black cameras.
