Wuxi Security Monitoring Some precautions in equipment maintenance: during the maintenance of the monitoring system equipment, some conditions should be prevented to make the equipment operate normally as far as possible. The main work needs to be done is moisture-proof, dust-proof, anti-corrosion, lightning protection and interference prevention.
Damp proof, dustproof and anti-corrosion
For various acquisition equipment of the monitoring system, since the equipment is directly placed in a dusty environment, which will have a direct impact on the operation of the equipment, it is necessary to focus on the maintenance of moisture, dust and corrosion prevention. as video camera If it is hung at the end of the shed for a long time, the protective cover and the dust proof glass will soon be covered with a mixture of dust, carbon ash, etc., which is dirty, black, corrosive, seriously affecting the viewing effect, and also bringing damage to the equipment. Therefore, the dust proof and anti-corrosion maintenance work of the camera must be done well. In some places with heavy moisture, the installation position and equipment protection must be adjusted during maintenance to improve the moisture-proof ability of the equipment itself. At the same time, dehumidification measures should be taken frequently in high humidity areas to solve the moisture-proof problem.
Lightning protection and interference prevention
As long as anyone who has been engaged in the maintenance of electromechanical system knows, it is common for equipment to be struck by lightning in thunderstorm weather, which will cause great potential safety hazards to the normal operation of monitoring equipment. Therefore, the monitoring equipment must attach great importance to lightning protection during the maintenance process. Lightning protection measures are mainly to do well in the lightning protection grounding grid for equipment grounding, and to do well in the integrated grounding grid with independent grounding resistance less than 1 ohm according to the equipotential body scheme. It is prohibited to mix the lightning protection grounding of weak current system with the power lightning protection grounding grid, so as to prevent the interference of the power grounding grid clutter on the equipment.
Anti interference is mainly to adhere to the principle of separating strong and weak electricity when wiring, separate power cables from communication cables and video cables, and strictly follow the wiring specifications of communication and power industries. For cameras installed outdoors, the camera must be insulated from the pole, and the camera must be insulated from the protective cover.
