Outdoor camera protection level IP66 / IP67 and lightning protection grounding points

How to read IP protection level

The first number after IP is Dust-proof grade (0~6), and the second number is Waterproof grade (0-9K). Common outdoors:

Note: IP67 does not mean "long-term soaking in water". The sealing ring will age under hot and cold cycles and ultraviolet rays, so long-term water accumulation still needs to be avoided.

Waterproof installation details

• Connector facing down: The crystal head of the network cable and the power connector must face downward or make a drip bend to prevent rainwater from flowing in along the line.
• Use a waterproof box: Install a waterproof junction box at the outdoor wiring location and wrap it with waterproof glue/self-adhesive tape.
• Sealing of cable entry holes: The cable entrances at the bracket threading holes and pole hand holes must be sealed with glue.
• Do not install upside down: Installing non-anti-inversion models upside down will damage the waterproof structure.
• Sunshade and anti-high temperature: Install a sunshade to reduce internal condensation and component aging.

Three-level lightning protection

1. Direct lightning protection: A lightning rod is installed on the top of the pole, the protection range is calculated according to the rolling ball method, and the down conductor is prepared.
2. Inductive lightning protection: Install a network + power two-in-one lightning protector on the front of the device. This is the easiest to omit but the most effective link.
3. Grounding: Lightning arresters, equipment shells, poles, and metal brackets are grounded uniformly. The recommended grounding resistance is ≤ 10Ω (important areas ≤ 4Ω).

Other suggestions

• In thunderstorm-prone areas, metal-cased equipment is preferred and equipotential connections must be made.
• Lightning protectors must be installed at both ends of long-distance overhead cables.
• Inspect the status of the lightning protection device once a year before the thunderstorm season. After being struck by lightning, the lightning protection module should be replaced even if the equipment is normal.
• Install voltage stabilization and overcurrent protection at the power supply end to avoid batch damage caused by voltage fluctuations.
