CCTV & Video Equipments

Closed-circuit television (CCTV) also known as video surveillance. They are used for video cameras to transmit signals to specific places or to specific sets of monitors. GAO Tek offers a wide range of high quality and affordable CCTV and video related equipment such as multi-functional CCTV testers and color video quad processors.
The color video quad processor systems take analog video from the input and control the video output based on the user’s preference. These processors allow the users to control the video output using different display modes such as quad split, full screen, PIP (picture in picture), dual screen, image motion detection, independent adjustment, video parameters, and auto sequence.
Multifunctional CCTV testers can be used for on-site installation or maintenance of IP cameras, analog cameras, network devices, video displays, PTZ controls, audio tests, and color generators. Some of them have the functions of POE power supply testing, PING testing, IP address scan, video screen shot, video record, image magnification, port flicker, cable search, and LED lamp.

Functions of CCTV and Video

CCTV and video devices control the video output of monitors, some of them can also be used in conjunction with video surveillance VCR recorders. Moreover, some of them include the power supply and a wireless remote control which allows users to access all settings and controls. These gadgets are used with digital technology to process and store the video information received from a camera. The incoming video image is transformed into a digital signal by an analog-to-digital (A/D) converter. This information is stored in memory and clocked out at a rate predetermined by the video processor. This clocking rate synchronizes the incoming video signals from the several cameras and enables them to be combined with a single video output in full screen or in quad format. 

Features

CCTV and video devices can work in real-time monitoring with a built-in clock, and date generator so it is easy to track every sequence. CCTV and video devices have an alarm mode which can be enabled for video loss, video motion, or external alarm. CCTV and video devices have a selectable sequence switch which can provide single-screen or picture-in-picture and zoom/freeze images. Some of them need the power source and some of them are wireless remote controlled. CCTV and video testing devices are portable instruments which make them easier for CCTV professionals to set up and maintain CCTV systems, thus, improve work efficiency by reducing time in the field.

Applications and Industries

CCTV and video devices are designed for surveillance in areas that may need monitoring such as banks, casinos, criminal use, airports, industrial plant area, military institutions, and convenience stores. They are also used in the public area and crime prevention places as well as in schools, extensive traffic-monitoring systems, on subway trains, control of retail stores, and home security.
