The sensing system of a modern smart door is like a symphony orchestra:
Infrared sensor: Responsible for basic human body heat detection, with a reaction speed of 0.3 seconds.
Millimeter-wave radar: Detects minute movements through clothing, with a recognition distance of up to 5 meters.
AI vision module: Distinguishes between owners and visitors through posture analysis.
After fusing data from these three technologies, the false judgment rate can be reduced to below 0.02%.
Five innovative scenarios for contactless door opening:
Shopping return mode: When carrying items with both hands, a slight bend in the knee triggers the door to open.
Rainstorm emergency solution: Automatically expands the sensing range upon detecting raindrop speed.
Pet-friendly design: Adjusts the threshold based on the height of the collar chip.
Anti-tail random control: Determines the distance difference between multiple people through gait analysis.
Silent opening at night: Automatically reduces hinge noise after 10 PM.
Dynamic balance between safety and convenience: Latest technologies are breaking through traditional contradictions:
Electromagnetic locks can be manually opened in case of power failure.
3D structured light prevents photo/video hacking.
Local AI chip processes sensitive data without going to the cloud.
Door vibration monitoring automatically triggers backup power.
Abnormal opening and closing records generate mechanical analysis reports.
