Why use lightning protection in Xueliang Project
The "Xueliang Project" is to build public security prevention measures at the county, township, and village levels to extend public security precautions to the masses, mobilize social forces and the broad masses to jointly monitor video surveillance, and participate in public security precautions in order to truly realize security control Full coverage, no dead ends. "
However, once the monitoring front-end equipment is damaged by lightning, it will cause a black screen phenomenon when the signal transmission is interrupted. The equipment fails to achieve 24-hour real-time monitoring and cannot record sudden security events, which affects the overall normal operation of the system. Workers need frequent manual maintenance, which increases the workload. The overall image was damaged due to image loss, and leaders even questioned the capabilities of the operations and maintenance leaders.
If the environment is bad in thunderstorms, the staff must go out for repairs in a timely manner. The coverage of rural equipment points is large and scattered. The maintenance time spent by the maintenance staff is several times longer than that of the city, and the location of some repair points is easily affected. Lightning strikes did not guarantee the personal safety of emergency repair personnel.
Effect after using lightning protection
The Xueliang project installs lightning protection products to protect the lightning protection products from all-round lightning protection, which is conducive to the continuous normal operation of the equipment in the 24-hour real-time monitoring during the thunderstorm season, reducing the black screen of the system, thereby ensuring system transmission The overall operation of the network. The signal transmission is uninterrupted for 24 hours, the overall complaint rate of customers has dropped, and the public image has been greatly improved.
How to choose a lightning arrester
At present, the number of lightning protection devices is increasing, and buyers are prone to selectivity problems. So how to choose the correct lightning protection device, the following will explain to you.
First determine the distance between the optical machine, the switch and the camera. You only need to install a power lightning arrester if the network cable length is less than 10 meters. If the distance between the two is more than 10 meters, you need to choose a network signal + power lightning arrester. .
Second, if the distance between the two switches is 30 meters, you need to choose to install a network signal + power lightning arrester.
It is necessary to choose a professional production type brand that is manufactured in accordance with national lightning protection standards to ensure that the quality and effect are guaranteed. Lightning arresters manufactured by Aomeco are strictly in accordance with national standards GB18802.1-2011 and GB / T18802.21-2004 . These products are simple to install, convenient to construct, have good shielding effects, explosion-proof, and fire-retardant.
