WHAT IS CCTV Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint, or mesh wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores. http://www.cctvcams.in Surveillance cameras on a corner Dome CCTV cameras
In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing Digital Video Recorders (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion-detection and email alerts). More recently, decentralized IP-based CCTV cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation.
CCTV Cameras : CCTV systems have become extremely popular over the last few decades as the technology has improved and become more affordable. The majority of CCTV cameras in use today are usually for surveillance and security purposes. CCTV systems can be found in almost every bank, casino, mall, and large department store. In fact, CCTV systems have become so affordable, most smaller mom and pop stores also have CCTV systems in them for security purposes.
TYPE OF CCTV There are many types of CCTV cameras. They can be categorized by the types of images they are able to capture, the amount of frames they can take per minute, the type of connection to the monitor or video recording device, whether they are able to move position, and special functions they can provide. Types of Images: CCTV cameras generally take both black and white or color video images. In addition, many CCTV cameras even have night vision capabilities that allow a CCTV camera to view and record low light images using special technology. Frames per Second: Frames per second is the amount of full frames that a video camera captures and sends to a recording device or monitor per second. While most CCTV camera systems easily capture 30 or more frames per second, the amount of video tape or digital storage would be enormous to record every moment of everyday. For most stores, speeds of 1 to 6 frames per second are more than enough to catch and record a perpetrator committing a crime. Pan Tilt Zoom Cameras: These types of CCTV cameras allow a person controlling the surveillance of an area to move the camera remotely, usually with an RF or wired controller. Most movable cameras allow the person monitoring it to move the camera from right to left , up and down.
Cameras with Special Accessories: Certain CCTV cameras have special functions that are made for specialty uses. For instance, there are extremely small surveillance cameras that are used for spying (Nanny Cams), night viewing, are vandal resistant, and that are specifically made for indoor or outdoor uses. • Wired Vs. Wireless Connection • There are two main types of connections for CCTV cameras: a fixed cable or a wireless connection. • Fixed Cable Connection • Fixed cable connection means that the camera is physically connected to the monitor or recording device via a cable. Coaxial cables that are similar to normal home TV cables are usually used. Lengths come in 25, 35, 50, 100, or 500 feet. As the distance increases, signal quality decreases. For distances longer than 100 or 200 feet, purchase higher quality coaxial cables such as RG59 coaxial cable for distances up to 600 feet and for distances more than 600 feet, but less than 2,000 feet, purchase CAT5 cable.
