Key points of lightning protection and operation and maintenance of outdoor cameras, the failure rate can be significantly reduced in rainy season
Lightning strikes, water intrusion and power failure are the main causes of outdoor point failures. Standardizing grounding, installing surge protection and regular inspections can significantly improve system availability.
Three major reasons for failure
- Lightning strikes and surges: Intrude along power lines and network cables, damaging cameras and switches;
- Water and moisture:The connector is not waterproofed and short-circuited in rainy season;
- Unstable power supply: Voltage fluctuations or insufficient adapter power cause restarts.
Protective measures
- Pole and equipment box are reliably grounded, and the grounding resistance meets the requirements;
- Install Surge Protector (SPD) on the power supply and network side;
- Use waterproof box + waterproof tape for network cable connector;
- Configure UPS or PoE power supply redundancy at important points;
- Choose IP66/IP67 protection grade equipment.
Inspection list
It is recommended to check the picture clarity and angle offset once a quarter, clean the lens and shield, Test the fill light and wipers, check the integrity of the video, and check the box seal and cable aging.
