Product Description

KNF 2 in1 High-definition Digital Camera Special 

Lightning Protection Gate

 

KNF 2in1 high-definition digital camera special lightning protection gate is specially used for two kinds of 

line surge protection of power monitoring system, RJ45 network line with network function, according to

the IP function with monitoring equipment (equipment, IP camera) protection: such as high-speed ball 

machine, constant speed ball machine, constant speed monitoring cameras and other equipment. Widely 

used in the monitoring system of the bank, residential security system, school, enterprise, road safety

protection monitoring equipment.

Note:With a special connector series in the loop,impedance connectors are 50Ω,75Ω;joint type has N,F, BNC, L16,7 / 16 and other models,determined by the user based on the device being used to protect joints.

 

Installation And Maintenance

1.This product series in the protected equipment signal circuit, and close to the protected equipment.

2.The input(IN) and output(OUT) cannot be reversed; the input(IN) is the lightning intruding end, output  

   (OUT) is connected with the protection device.

3.For the normal work of SPD, grounding is very important, the grounding wire cross-sectional area is 

   no less than 4m square meters, and as short as possible.

4.Lightning protection gate without special maintenance, but its long-

   term energized, so need messenger to inspect regularly, especially in the thunderstorm season, after the 

   lightning strike, it should be inspected on time, if found that the loop signal is abnormal, removing 

   protection gate, loop signal will back to normal, it means Lightning protection gate has been damaged or

   life has ended, replace the new lightning protection gate on time.

5.The outside length of Coaxial line more than 30m,it should be in the coaxial two ends with lightning

   protection gate to ensure the better lightning protection effect.
