Circuit protection for smart home security devices (such as doorbells and door locks)

2025-09-11

Application Scenario: Microprocessors and sensor circuits within smart doorbells and smart door locks installed outdoors.

Challenges: Large temperature swings between day and night leading to internal condensation, high humidity during the rainy season, difficulty starting at low temperatures in winter, and the risk of lightning surges.

Solution: Completely potting the main control PCB, encapsulating all components in a gel.

Core Value: Completely eliminate circuit corrosion and short circuits caused by condensation, ensuring normal operation of the equipment in both extreme cold and heat. The gel's excellent electrical insulation properties provide excellent isolation and surge protection, extending product life and user safety.
