FAQ
Common questions about LY23 BNC coaxial video signal surge protector selection and installation.
What is the LY23 BNC video surge protector used for?
LY23 is installed inline with a BNC coaxial video cable to help prevent lightning-induced and switching transient overvoltage from reaching cameras, recorders, monitors, and video-control equipment.
Which systems commonly use LY23?
Typical applications include analog CCTV cameras, DVR video inputs, video matrix systems, monitors, optical video transmitters and receivers, and other BNC coaxial surveillance equipment.
Will LY23 affect video signal quality?
The listed insertion loss is no more than 0.2dB and the maximum transmission rate is 10Mbps. Compatibility should still be checked against the actual video format, impedance, cable type, and transmission distance.
Does LY23 require an external power supply?
No. It is a passive inline protection device and does not require an external power supply.
How should LY23 be installed?
Install it inline with the BNC coaxial cable and as close as practical to the protected equipment. Follow the input and protected-side markings and keep the grounding connection short and direct.
Que doit-on confirmer avant de commander ?
Confirm the BNC connector type, signal voltage, video format, cable impedance, transmission rate, cable length, grounding method, installation location, and required surge withstand level.
