Waterproofing CCTV and Outdoor Camera Electronics

Outdoor security cameras live in rain, fog, temperature swings and condensation. Even IP-rated housings can let moisture in through cable entries and aging seals. Coating the internal board adds a second line of defense.

Where moisture gets in

Most outdoor cameras fail not because the lens floods, but because humid air enters through cable glands and worn gaskets and then condenses on the board. A coating protects the electronics even when the housing seal weakens.

Coat the board, mask the optics

Apply the coating to the main PCB, power section and connector pads. Mask the image sensor, lens, IR LEDs and microphone so image and audio performance stay unchanged.

Protect connectors and cable entries

Corrosion at the RJ45 or power connector is a common failure point. Reinforce these areas and the cable entry with a brushed layer for extra moisture and salt resistance.

Result: fewer field failures

A coated board survives fog, light leaks and condensation far better, which means fewer service visits and longer camera life in outdoor and coastal installations.
