Multi functional CCTV Testers
Gao Tek offers a wide range of high quality and affordable multifunctional CCTV testers. The multifunctional CCTV testers can capture video images and save the current video frames as JPEG files. They also eligible to record and save the current video on an SD card and make directories which can be created according to the date. These devices are simple and convenient multifunctional measurement test tools which provide monitoring and analytical data when installing and maintaining the CCTV systems for video levels and video signals of the image.
Multifunctional CCTV testers send the specific signal so it is easy to find the connected cable. The testers send special signals to make the connected POE port flicker at a special frequency, which will enable the installers to easily and quickly find the connected Ethernet cable. These functions may prevent mistaken insertions or disconnection of non-corresponding cables. Videos generate the PAL/NTSC multi-system by receiving the video color bar to test the video channel. They judge whether the color is different, because of the transmission loss or interference. These are suitable for video transmission of the field tests, such as optical video transmitters and receivers, and video cables. Moreover, multifunctional CCTV testers have optional functions such as digital multi-meter, optical power meter, visual fault locator, TDR (time-domain reflectometer) break-point, and short-circuit measurement.
Multifunctional CCTV testers are developed for the on-site installation and maintenance of IP cameras, analog camera and network devices, video displays, PTZ (pan, tilt and zoom) control audio tests, and color generators. Some of them developed functions include POE power supply testing, PING testing, IP address scan, video screen shot, video record, image magnification, port flicker, cable search, and LED lamp. The testers also have built-in TDR cable testing, which is designed for BNC cable testing in the security monitoring system. These functions can accurately measure BNC cables and network cable’s break points and short-circuit locations. The multifunctional CCTV testers have built-in LCD displays which support PAL/NTSC brightness/contrast/color saturation. They have video signal strength attenuation. These also can display the video level values, input video images and notice if the signals are out of range. The devices can setup the controlling parameters like protocols, communication ports, baud rates, pan/tilt speeds; sets and call positions. The devices are designed with easy operation and portability which make them simple for a CCTV technician or installer to install and maintain CCTV systems, thus, improving work efficiency by reducing time in the field.
Multifunctional CCTV testers are widely used for CCTV system installation and maintenance. These are needed to professionally install a CCTV system; maintain the CCTV system, the test functions include video level, and service monitor.
