Cctv : Closed-circuit television (CCTV), also known as video surveillance. There are lots of CCTV cameras to choose from on the market today, with many different features and options, resulting in a confusing array of various types, styles, and configurations. But which is best for your intended business security application?
1. Dome CCTV Camera
Dome CCTV Cameras are most commonly used for indoor security and surveillance applications. Dome cameras get their name from the dome-shaped housing in which they sit. These housings are designed to make the CCTV cameras unobtrusive… not covert or
hidden. Typical applications are retail, where the camera is designed to be unobtrusive, but visible.
2. Bullet CCTV Camera
Bullet CCTV Cameras have a long, cylindrical, and tapered shape, similar to that of a "rifle bullet", often used in applications that require long distance viewing. The camera is not typically designed to have pan/tilt/zoom control but instead to capture images from a fixed location, pointing at a particular area.
3. C-Mount CCTV Camera
C-mount CCTV cameras have detachable lenses to fit different applications. Standard CCTV camera lenses can only cover distances of between 35 and 40ft, therefore with C-mount CCTV cameras, it is possible to use special lenses, which can cover distances greater than 40ft.
4. Day/Night CCTV Camera
The day/night CCTV cameras have the distinct advantage of operating in both normal and poorly-lit environments. These cameras do not have Infrared illuminators because they can capture clear video images in varying light conditions.
The camera is ideal for outdoor surveillance applications, where Infrared CCTV cameras cannot function optimally. These CCTV cameras are primarily used in outdoor applications and they can have a wide dynamic range to function in glare, direct sunlight, reflections and strong back light 24/7 now all the brands are making infrared/night vision cctv camera.
5. Infrared/Night Vision CCTV Camera
These night-vision CCTV cameras have the ability to see images in pitch black conditions using Infrared LEDs and are ideal in outside conditions where lighting is poor to zero.
6. Network/IP CCTV Camera
These cameras, both hardwired and wireless, transmit images over the Internet, often compressing the bandwidth so as not to overwhelm the web. IP cameras are easier to install than analog cameras because they do not require a separate cable run or power boost to send images over a longer distance.
7. Wireless CCTV Camera
Not all wireless cameras are IP-based. Some wireless cameras can use alternative modes of wireless transmission. But no matter what the transmission method, the primary benefit to these units is still the same: extreme flexibility in installation.
8. High-Definition HD CCTV Camera
Ultra high-definition cameras are often relegated to niche markets, such as casinos and banks. These give the operators the ability to zoom in with extreme clarity (to look at a poker player who might have something up their sleeve).
Beyond this list, there are many other types of CCTV cameras, but most of those are more related to the application in which the unit will be used vs. the type of camera.
