Smarter Adaptive Lighting - Noonkey PTZ camera uses intelligent analysis technology to identify objects, autofocus and dimming when a strongly reflective object is recognized, the ambient light sensor dims or brightens the lamp beads (8pcs crystal beads) based on the current lighting conditions in the space to achieve the best night viewing effect. Refuse to expose images, see clearly what is approaching even in the dark. Advanced Instant Alarm - Sound alarm supports turn on/off manually, you can adjust the siren volume and the length of siren time by APP. Spotlights will turn on when the camera detects motions automatically (at dark, under auto night vision mode, support delayed light up). Spotlights also support turning on/off manually and adjusting brightness manually. Noonkey attaches great importance to safety and provides you with peace of mind. Custom Monitoring Area - In Smart Life/Tuya Smart APP, you can draw a custom area to detect motions. No worries about false alerts and unwanted monitoring areas anymore.
