Solving, monitoring why such a flash?

Solving, monitoring why such a flash?

Answer:

This part is relatively fast learning, a lot of field environment is not seen a few days after the construction can determine how, how to judge the scene of environmental monitoring, anti-theft, the running effect of access control system equipment will have to take a close look at the following article.Venus, through the analysis of the security problem of long-term practice and probably the following scene will cause the classified video interference factors, signal instability: 1 large signal transmission tower equipment (mobile, China Unicom, the 2 signal tower): field equipment field (metal, five gold, 3 machinery plant): power supply load equipment (project on-site electricity unstable) 4: the installation position is not strong (air, air vehicles, lifting equipment on the side of) 5: corrosion resistance, poor environment (the recent riot to launch)
The security system for its front-end equipment, infrared cameras, PTZ, high-speed ball, and anti-theft system in infrared, infrared probe, working voltage of power supply in the DC12V or DC24V, is a kind of weak current system. When the power supply is supplied, the front end equipment is about 150 meters away from the total power supply center of the engine room, and the whole circuit does not have enough power to supply power directly from the centralized power supply of the monitoring room. If the distance is between 150 meters and high, it is recommended that the 220V be sent directly to the front end, and the power supply will be switched into the voltage required by the equipment through the regulated power supply.
If the monitoring front-end power supply, you can consider adding video anti-jamming device, it is recommended to use the end of a unified power supply way to monitor power supply, generally plus regulated power supply can solve the problem, but not absolute. You can use the following methods to determine the cause of the interference
