Surveillance cameras which are popularly known as CCTVs (Closed-circuit televisions), employ video cameras to send signals to a specified location, on a set number of monitors. The name surveillance’ comes in as the video cameras are used for monitoring installations such as military facilities, homes, banks, airports, stores and casinos just to mention a few. Surveillance cameras have a wide area of application. One such area is in the industrial plants. The work of the camera is to monitor some of the parts in the plant such as the central control room. Surveillance cameras may be used only for one particular event or they may be used for round the clock surveillance.
Recent innovation of security cameras has led to the development of decentralized IP cameras. Some of these IP cameras are equipped with powerful megapixel sensors. They support direct recording of video footages to a network-attached storage devices. In most developed countries, surveillance meant for public places. In the past few years the use of micro-video cameras that can be worn has been on the rise especially by the law enforcement agencies.
The use of surveillance cameras has increased and today they are deployed in many towns, city centres, car-parks, gas-stations and residential places. The use of surveillance cameras has been seen as an effective way of reducing crime in various places such as parking lots and public transport areas. They enable one to see what is happening on the ground without having to be there in person. Surveillance cameras at homes are used by parents to monitor a sleeping child. This reduces the risk of the child falling down from the crib. A surveillance camera that is installed inside the house or at the door will record any person coming in and can be used to catch a burglar.

Surveillance cameras come in different unique sizes, designs and capabilities. When buying a set of surveillance cameras, they are a few factors that need to be put into consideration. To begin with, you will first need to consider what you will be watching and the equipment that you will require to watch it. The number of cameras that will be used will depend on the area that you want to put under surveillance. Surveillance cameras may be wired or wireless. When you want the surveillance cameras to be hidden, wireless cameras are the best. Wired cameras are sophisticated to install and the stray wires may sell you out if you wanted the cameras to remain hidden. However, when it comes to quality of footages, wired cameras are much better than the wireless cameras as their signals travel through a wire and not through the air.
Wireless cameras are very flexible and can be installed almost anywhere. Wireless cameras can be interrupted by broadcasts of signals by other devices such as baby monitors, wireless internet and cordless phones. The signals of a wireless camera can also be intercepted by another party. To secure the signals of the wireless cameras, one can invest in cameras that use encryption technology in transmitting video feeds.
