Application:
It is mainly used for lightning protection for HD network cameras at the front end of the monitoring system
It can effectively absorb and discharge electromagnetic interference, pulse and other line surges in power lines and network cables, and protect monitoring equipment from lightning strike.
Installation and Maintenance:
Installed in series between the protected equipment and power line.
The output end is connected with the protected equipment, which can not be connected in reverse.
After installation and wiring, check that the wiring is correct and firm, then switch on the power supply and put into use
