Lightning, anti-disturb only worked to protect jobs electromechanical system knows, a thunderstorm weather, the lightning strike are common to the normal operation of the monitoring device to form a big security risk, therefore, monitoring equipment in the protection process the question is necessary to attach great importance to the mine. The primary way is to do mine equipment ground lightning ground network security maintenance program shall be planned, such as the potential to do an independent body to less than 1 ohm resistance induction grounding grid, lightning protection and grounding with the power to eradicate anti-weak system Ray grounding grid mix maintenance of a single security practices to prevent electrical grounding network equipment clutter disturb occur. Anti disturb the primary should adhere to the strength of electrical wiring to achieve separate criterion, the power cable communication cable and video cable with separate security maintenance, in strict accordance with standard communication wiring and power industry and construction. There are many types of surveillance cameras currently on the market there are many high imitation camera technology, high imitation camera when in use, compared to the regular camera has many faults, such encounter PTZ use soon dysfunctional Or can not turn the issue here is to give an analysis of the specific reasons: 1, too far away when the camera can not operate the keyboard cameras (including lenses) and PTZ remotely via decoders. The main reason for this phenomenon is that because the distance is too far, the effect of the operation panel of the control signal will be greatly reduced, in this case the control signal decoder received will be too weak. Then the relay box should be installed in a certain distance to amplify the control signal. sony security source Maintenance Repair _ (certified) _ Zhengzhou, Kaifeng security service provided by the source Electronic Technology Co., maintenance.
