Human Body Sensing: Typically uses PIR (Passive Infrared) sensors or millimeter-wave radar to detect movement in front of the mirror, enabling automatic light on/off.
PIR Sensor: Cost-effective but may not detect static presence (e.g., lights may turn off during prolonged makeup sessions).
Millimeter-Wave Radar: Higher sensitivity, capable of detecting subtle movements (e.g., breathing), ideal for premium models.
Ambient Light Sensor: Works with the motion sensor to activate only in low-light conditions, preventing unnecessary daytime activation.
Touch-Free Operation: Avoids smudges or water stains on the mirror surface.
Energy Saving: Automatically turns off when no motion is detected, perfect for bathrooms or dressing rooms.
Adjustable Delay: Some models allow setting a custom delay (e.g., 10 sec – 5 min) before turning off.
Bathroom Mirror: Lights up automatically during showers, even in steamy conditions.
Closet Mirror: Illuminates when the door opens for easier outfit selection.
Smart Home Integration: Compatible models can sync with HomeKit, Mi Home, etc., enabling automation (e.g., turning on the exhaust fan when the mirror activates).
Waterproof Rating: Choose IPX4 or higher for bathroom use (splash-proof).
Power Supply: Battery-operated (flexible installation) or wired (stable power).
Additional Features: Some models include anti-fog, digital clock, Bluetooth speaker, etc.
Installation: Check whether it requires wall mounting or supports adhesive installation.
False Triggers: Adjust sensitivity or reposition the mirror (avoid placing near air vents).
Nighttime Disturbance: Opt for models with soft nightlight to avoid harsh glare.
Entry-Level: Teruier T1 (PIR sensor, IPX4, budget-friendly).
Premium: Teruier Pro (millimeter-wave radar, app control, anti-fog function).
Purchase through official channels and confirm warranty terms (e.g., waterproof coverage). Some sellers offer free video installation guides.
