closed-circuit television (cctv) camerascan produce images or recordings for surveillance purposes, and can be either video cameras, or digital stills cameras.
video camerasare either analogue or digital, which means that they work on the basis of sending analogue or digital signals to a storage device such as a video tape recorder or desktop computer or laptop computer.
analogue
can record straight to a video tape recorder which are able to record analogue signals as pictures. If the analogue signals are recorded to tape, then the tape must run at a very slow speed in order to operate continuously. This is because in order to allow a three hour tape to run for 24 hours, it must be set to run on a time lapse basis which is usually about four frames a second. In one second, the camera scene can change dramatically. A person for example can have walked a distance of 1 meter, and therefore if the distance is divided into four parts, i.e. Four frames or "snapshots" in time, then each frame invariably looks like a blur, unless the subject keeps relatively still.
analogue signals can also be converted into a digital signal to enable the recordings to be stored on a pc as digital recordings. In that case the analogue video camera must be plugged directly into a video capture card in the computer, and the card then converts the analogue signal to digital. These cards are relatively cheap, but inevitably the resulting digital signals are compressed 5:1 (mpeg compression) in order for the video recordings to be saved on a continuous basis.
another way to store recordings on a non-analogue media is through the use of a digital video recorder (dvr). Such a device is similar in functionality to a pc with a capture card and appropriate video recording software. Unlike pcs, most dvrs designed for cctv purposes are embedded devices that require less maintenance and simpler setup than a pc-based solution, for a medium to large number of analogue cameras.

TheBNC connector(Bayonet NeillConcelman)is a miniature quick connect/disconnect RF connector used for coaxial cable. It features two bayonet lugs on the female connector; mating is achieved with only a quarter turn of the coupling nut. BNCs are ideally suited for cable termination for miniature-to-subminiature coaxial cable (e.g., RG-58, 59, to RG-179, RG-316). It is used with radio, television, and other radio-frequency electronic equipment, test instruments, video signals, and was once a popular computer network connector. BNC connectors are made to match the characteristic impedance of cable at either 50 ohms or 75 ohms.
