Different Types of Security Camerasby Steve Johnson
In surveillance, having a reliable security camera is crucial. It allows monitoring of activities and recording of events as potential reference in cases of vandalism, trespassing, theft or other crimes. Banks, retail stores, schools, hotels and many business establishments install CCTV (closed-circuit television) surveillance systems as high security measures. For anyone thinking of installing a security camera, there are a number of types to choose from, each with its own set of advantages.
Infrared Security Camera
Infrared security cameras---also known as "night vision cameras"---can work for both dark and well-lit areas. With a lit area, infrared security cameras project a color picture, while the camera projects a black-and-white image for night scenes. The key to infrared cameras is their ability to detect infrared radiation, which includes body heat; this allows them to have the useful ability to "see" at night.
Dome Security Cameras
As the name implies, this high-end security camera is shaped like a dome, usually affixed on a ceiling. Dome security cameras normally appear black. They are commonly found in banks, casinos, airports and offices. The advantage of this type of camera is that the dome that covers the camera lens makes it quite hard to decipher where the camera is pointed.
IP/Network Security Camera
An IP camera---or "network camera"---is a web-based security camera that can be manipulated, viewed and recorded from any remote location in the world. With its built-in web server, it is connected to a network and has its own IP address to allow communication and function over the Internet. A remote-viewing camera can be many different types of video recorders, ranging from dome to CCTV cameras.
Wireless Security Cameras
If you are after portability, mobility, versatility and disguise, then a wireless security camera may be a good option. Generally reserved as a spy camera, wireless cameras can be disguised as nearly anything; some can even be small enough to fit on the button of a jacket. Rather than wires, it utilizes a transmitter that runs on batteries to broadcast the image to a local receiver.
