Outdoor surveillance cameras: outdoor cameras are exposed to all weathers, so air tightness testing ensures their waterproof sealing and keeps moisture and dust away from the electronics.
Security lighting: outdoor lamps and street lights also need good waterproof and air tightness performance to work reliably in bad weather.
Alarm systems: underwater alarms and similar devices must pass air tightness testing to be reliable underwater.
Smart door locks: as smart locks become part of security systems, air tightness testing confirms they remain safe in damp environments.
Communication base stations: some base station equipment is installed outdoors; air tightness testing safeguards stable operation in harsh conditions.。
Explosion-proof equipment: some security equipment must be explosion-proof, and air tightness testing verifies the sealing needed for safe use.
Rugged phones: waterproof, dustproof and shockproof phones are widely used by field staff, and air tightness testing protects their internal components.
