CCTV

Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a specific, limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point wireless links. CCTV is often used for surveillance in areas which need security, such as banks, casinos, and airports or military installations. In industrial plants, CCTV equipment may be used to observe parts of a process that are remote from a control room, or where the environment is not comfortable for humans. CCTV systems may operate continuously or only as required to monitor a particular event.

Network DVR

Network DVR.function is similar to that of a digital video recorder except it stores it content on a network instead of a local hard disk. The technology operates in the same manner as VOD except the consumer decides what to record rather than the operator.

Night Vision

Night Visiondevices gather existing ambient light (starlight, moonlight or infra-red light) through the front lens. This light, which is made up of photons goes into a photocathode tube that changes the photons to electrons. The electrons are then amplified to a much greater number through an electrical and chemical process. The electrons are then hurled against a phosphorus screen that changes the amplified electrons back into visible light that you see through the eyepiece. The image will now be a clear green-hued amplified re-creation of the scene you were observing.

Mobile DVR

Mobile DVR.function is similar to that of a digital video recorder except it stores it content on a network instead of a local hard disk. The technology operates in the same manner as VOD except the consumer decides what to record rather than the operator.Also the DVR is accessable through internet connections to view at other locations.

Stand Alone DVR

Stand Alone DVR.is a digital video recorder (DVR) (or personal video recorder (PVR)) is a device that records video without videotape to a hard drive-based digital storage medium. The term includes stand-alone set-top boxes and software for personal computers which enables video capture and playback to and from disk.

Cabling

Cabling.is two or more wires or optical fibers bound together, typically in a common protective jacket or sheath. The individual wires or fibers inside the jacket may be bare, covered or insulated. Combination cables may contain both electrical wires and optical fibers.

Encoder

Encoder.is a device used to change a signal (such as a bitstream) or data into a code. The code may serve any of a number of purposes such as compressing information for transmission or storage, encrypting or adding redundancies to the input code, or translating from one code to another. This is usually done by means of a programmed algorithm, especially if any part is digital, while most analog encoding is done with analog circuitry. For your CCTV system.

Digital Video Processor

Digital Video Processor.General term used to refer to a device that accepts a raw video signal as an input makes beneficial modifications to that signal and outputs the modified video stream. Or, they can be external, stand-alone devices that are dedicated to one purpose and do not have to share resources with other activities within a display device.
