Multi-functional CCTV testers send special signals to make the connected PEO port flicker at a specific frequency which will enable the installers to quickly find the connected Ethernet cable. These devices prevent incorrect insertion and disconnection of non-corresponding cables. Videos generate PAL/NTSC multi-system by receiving the video color bar to test the video channel. Thus, the testers work by deciding whether the color is different due to transmission loss or interference.

The devices are ideal for video transmission 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.
