Lightning, anti-disturb only worked to protect jobs electromechanical system knows to find surveillance installation, a thunderstorm weather, the equipment was struck by lightning are common to the normal operation of the monitoring device to form a big security risk mall surveillance installation, thus monitoring equipment is necessary to protect the process of lightning doubt very seriously. The primary way is to do mine equipment ground lightning ground network, should plan to do an independent body, such as the potential of ground resistance of less than 1 ohm inductive grounding grid, lightning protection and grounding eradicate and weak electricity network system lightning protection and grounding mixed approach to prevent clutter power ground network equipment disturb occur. Anti disturb the wiring should be done first and foremost insist on separate criteria for monitoring the strength of electrical installation, the power cable communication cable and video cable with separate enterprise monitoring installation, in strict accordance with standard communication wiring and power industry and construction. Security monitoring devices ? This safety monitoring device uses SONY high sensitivity image sensor, the output resolution images · backlight compensation function * Low security monitoring equipment power consumption, stable performance, true 24-hour surveillance · infrared light using pulse drive, can effectively reduce the heat of infrared light and extend its life in order to do a good job monitoring equipment maintenance and repair center is equipped with appropriate human and material resources (tools, communications equipment, etc.), responsible for the daily monitoring of the monitoring system, maintenance, service and management and undertake maintenance work devices to safeguard the long-term monitoring system, reliable and efficient operation.
