A CCTV monitor is primarily a device for surveillance, theft security and crowd control. Most advanced countries in the world have these devices installed within traffic lights as well as shopping areas such as malls. Initially, this gadget was extremely expensive and could be afforded only by large businesses. Nowadays, with the advent of advanced technology, home owners as well as small business owners such as retailers and shopkeepers have installed these appliances in order to keep any eye on their customers and visitors thereby ensuring safety.
The technology involved in CCTV monitoring was initially based upon cathode ray devices. However monitors based on this technology were slow and had low resolution which deterred the identification of important attributes such facial features. Moreover, these monitors also produced a lot of heat which decreased their life expectancy. Presently, CCTV monitors have adopted liquid crystal display (LCD) technology which allows for higher resolution as well as low heat production. Also, many security systems are setup in ways to enable viewing of several different locations at one time. For this purpose LCD monitors are ideal because they are thinner, lighter and available in large sizes.
In order to acquire the most appropriate CCTV monitoring system, one has to cater to several factors that can increase or decrease the efficiency of the structure. Firstly, one has to get a monitor that offers a large screen size and high resolution. Also, color monitors are recommended as well as viewing devices that have several different input port options. This is because the monitor needs to be able to connect to either a multiplexer as well as a normal camera. Advanced controls such as adjustment for brightness and contrast as well as support for night vision viewing.
Furthermore, one also has to consider the type of video format that can be supported. In general, most monitors have capabilities to accept PAL or NTSC. Some monitors have speakers which can prove useful if the camera installed within the premises is equipped with a microphone.
A CCTV LCD monitor can be used for a variety of purposes. The most common application is the installation of a camera at one’s front door to monitor activity. On the other hand, one can also connect a monitor to a camera installed within the bedroom of a sick family member as well as an infant. Consequently, enhanced real time 24 hours monitoring is the primary benefit for home owners.
A CCTV monitor is available in various models. The LCD version is preferred because it is more advanced as well as being available in large screen sizes for optimal viewing conditions.
