Why use lightning protection in a safe city
The biggest essential significance of the video surveillance and related equipment installed in the Safe City project is that it can realize real-time monitoring 24 hours in order to combat crime and maintain law and order. However, during a thunderstorm season, if the 24-hour real-time monitoring system has a black screen and the system cannot operate normally, staff need to perform manual maintenance frequently, which increases the workload, signal instability or interruption, and prevents sudden security events. Unable to record, it also affects social security work.
Effect after using lightning protection
In today's society, with the advancement of smart city construction and the popularization of lightning protection knowledge, lightning protection devices have also been widely used. For example, what is the failure rate of the monitoring system of a local public security bureau before the installation of lightning protection, how much the failure rate decreases after the installation of lightning protection, and the percentage of manual maintenance is reduced. Therefore, these measures can ensure the equipment's performance. Effective 24 hours work smoothly.
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 10 meters, you need to choose to install a network signal + power lightning arrester.
Third, if wireless transmission and reception are used, only a power lightning arrester needs to be installed.
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.
Recommended products and applications

I. Power lightning arrester with automatic recloser leakage protector
1. Model: AL-20K-6663-P20 "Click to view" AA-SCM-56-DB20 "Click to view"
2. What is the power consumption of the device after the power lightning arrester is installed according to the transmission mode? It has absolutely no effect on the equipment.
3.
⑴ Ensure that the front-end equipment can be used normally during the thunderstorm season, and the auto-reclosing device has leakage protection. After tripping, the power can be restored by itself without the need for manual site maintenance to ensure that the equipment can be monitored 24 hours in real time.
⑵ No need to install standard lightning protection ground wire, reduce manpower and material resources, and thus reduce the total cost of lightning protection projects.
(3) The appearance of the product adopts the national standard design, which conforms to the overall layout of the chassis and reduces the occupied space.
