PREGUNTAS FRECUENTES
Common questions about LY23 4-port and 8-port BNC video surge protector selection and installation.
What is the LY23 multi-port BNC surge protector used for?
It provides centralized surge protection for four or eight analog CCTV video channels connected through BNC coaxial cables.
What is the difference between the 4-port and 8-port versions?
The 4-port version protects four independent BNC video channels, while the 8-port version protects eight channels in one enclosure. Select the version according to the number of camera or recorder connections.
Which video signals does LY23 support?
The current product information identifies it for analog CVBS video signals transmitted through BNC coaxial cables.
Will it affect video transmission 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, cable impedance, cable length, and connected equipment.
Where should the multi-port SPD be installed?
It is typically installed in a surveillance or control cabinet near the DVR, video matrix, receiver, monitor, or other centralized video equipment.
What should be confirmed before ordering?
Confirm the number of video channels, BNC connector arrangement, video format, operating voltage, cable impedance, installation space, grounding method, transmission distance, and required surge-withstand level.
