Security monitoring system lightning protection application program
In order to avoid lightning damage to equipment, many people seek lightning protection programs. Many online programs are very long. They have the patience to read it, read it and don’t understand it, and they don’t know who to ask questions. After reading it, they don’t know how to choose the defense. Thunderbolt, then, there are the following solutions.
Second, how to choose the network camera SPD <br> <br> first to determine a first transmission mode, the transmission mode optical fiber or cable transmission modes; belonging to the above embodiment of FIG cable transmission modes, it is necessary to select the "power network port + The lightning protection device.
The second to determine the power supply mode, is to take power AC220V on-site or centralized power supply DC12V;
1. If the (AL-10K(412D)-S, AL-10K(412N)-S product application diagram) in the above scheme belongs to the centralized power supply DC12V, select the “power supply DC12V+ network port†lightning arrester. Such as AL-10K (412D)-S, AL-10K (412N)-S
2. The (AL-20K(412P)-S, AL-10K(412N)-S product application diagram) in the following scheme is local power AC220V, so choose the “power AC220V + network port†lightning arrester. Such as AL-20K (412P)-S, AL-10K (412N)-S
The third option is to choose a professional production type brand that is manufactured according to the national lightning protection standard, and ensure that there are lightning protection devices with guaranteed quality and effect.
Third, the advantages of AL-20K (412P)-S, AL-10K (412D)-S, AL-10K (412N)-S lightning protection device 1. The lightning protector manufactured by Australia-US high company implements the national standard GB18802.1 -2011, GB/T18802.21-2004 manufacturing, this type of product is simple to install, easy to use, signal channels and power channels at the same time lightning protection, safety, explosion-proof, impact resistance, shielding effect is good.
2. This kind of product has the function of loyalty and protection. When the lightning protector is completely damaged by a lightning strike, it can automatically cut off the power supply and block the lightning current so as to ensure that the monitoring equipment is not damaged by lightning.
3. When the lightning arrester of this type suffers major lightning damage, it can automatically repair internal faults, thereby greatly prolonging the service life of the product. Therefore, such products do not require manual maintenance and repair.
