Uses & Benefits of CCTV Testers

January 29, 2018   Site Security   No comments

CCTV (closed circuit television) installations are a line of defense that companies and individuals employ to increase the security of a building or home through remote surveillance of selected areas. Depending on the premises, the number of camera installations required may range from one to one hundred, or more. Most configurations will include a DVR (digital video recorder) for storing footage, and sometimes monitors and computers for viewing live feeds in a particular location. With the cameras set up in separate areas, installers may need to run between the video feed and camera in order to fine tune the settings. CCTV testers, also known as LCD field monitors or CCTV field monitors, offer installers an ideal solution that enables them to view the video feed from a camera in real time, as well as calibrate and troubleshoot based on the additional features they provide.

The most basic feature of a CCTV tester is an LCD screen, usually between 2.5 inches to 3.5 inches (diagonal), which allows installers to view the camera feed on the spot. Additional features for video calibration may include video test patterns, brightness/contrast/saturation adjustments, video signal intensity testing, and support for PAL and/or NTSC video. Some testers are capable of providing power to the camera, often up to 12VDC, enabling installers to mount and focus cameras in the optimal spot before running power cables.

Other functions a CCTV installer might require in a CCTV tester or in a separate device are: a multimeter, pan-tilt-zoom (PTZ) control, and a network/coaxial cable tester/tracer. The multimeter can usually verify that the camera is receiving the correct amount of AC or DC power and check the resistance of a cable. PTZ cameras enable remote directional and zoom control, which, depending on the type of camera, could be controlled by RS485, RS232, software, or web interface, amongst other options. With PTZ control on a CCTV tester, users can bench test or set up a camera without any additional equipment. Cable testers are great for troubleshooting cables for shorts and miswires. Some also include a cable tracer, making it easy to locate the other end of a cable during installations.

Regardless of additional features, most CCTV testers are compact and portable devices that allow easy field calibration, testing, and troubleshooting of CCTV installations. Higher-end units tend to support more functions, thus reducing the need to acquire and operate multiple devices for a single job. Video Products Inc (VPI) offers a selection of CCTV testers that can simplify the installation and troubleshooting process.

VPI’s TESTER-CCTV-W CCTV Tester with Wrist Strap displays NTSC/PAL video on a 2.5 inch LCD screen with a resolution of 480×234.

Secured by a wrist strap, the unit enables easy and hands-free installations without the hassle of running between a camera and DVR located in separate areas.

Requiring only a 3.7V Li-ion battery, the unit possesses a runtime of up to 12 hours.
