FAQ
Q1: DC power protection, control line signal protection
A: The common problems of DC power supply protection, control line signal protection and video signal protection are the same, and the connection mode is generally crimping type. The on-site engineering personnel must pay attention to the correct connection of such lightning arresters.
Q2 :Precautions for lightning protection of video signal
A:The concept of video signal lightning protection is relatively simple, but it often fails due to the negligence in the work link, and causes the video lightning protection itself to be damaged. At present, most of the signal lightning protection products on the market generally adopt two levels of protection, the former as the rough protection, the gas discharge tube as the protection device, the latter as the fine protection, and TV S as the protection device.
Q3: Protection of optical fiber communication line
A: Generally speaking, the optical fiber line does not need to be equipped with lightning surge protection device, because the optical fiber line itself does not belong to the conductor, and it will not sense and transmit overvoltage surge. However, it should be noted that the optical fiber cable generally has a metal reinforcing core and a metal armor layer to protect the optical fiber cable, so the grounding protection must be done at the entrance end of the optical fiber.
Q4: Protection of transmission lines
A: The safest way of wiring is to adopt the whole process of laying underground through metal pipes. At the same time, both ends of the metal pipes must be effectively grounded. In the actual project, in many cases, when the conditions are not allowed, the cables can be laid overhead through metal pipes in the whole process; or they can not be laid through metal pipes in the whole process, but the cables must be laid underground through metal pipes before entering the monitoring room and front-end equipment, the buried length should not be less than 15m, and the metal sheath and metal pipes of the cables can be effectively connected with the lightning protection grounding at the entry end. Surge protective devices shall be installed at both ends of all transmission lines.
Q5:Selection of surge protector for AC power supply
A:Effective lightning protection shall be provided for all incoming terminals of AC power supply of monitoring and security system. The corresponding power surge protector shall be installed at the AC power incoming line of the front-end equipment. Three level protection shall be considered for the power line entering the monitoring room. The first level power surge protector can be installed at the power incoming line of the general distribution room of the building, the second level power surge protector can be installed at the power incoming line of the distribution box on the floor where the monitoring room is located, and the third level power surge protector can be installed at the power incoming line of the important equipment in the monitoring room.
