Operating Instructions
Artificial Intelligence (AI) Detection
The system utilizes Vision AI technology for precise human and vehicle detection. This minimizes false alarms by distinguishing relevant motion from other movements. Notifications are sent to your mobile app when human or vehicle activity is detected.

4K Ultra HD ClearVu™ Technology

Vivid Color Night Vision and Spotlight Deterrence
Cameras are equipped with dual infrared LEDs and ultra-bright white light LEDs to provide vivid color night vision up to 66 feet. The integrated spotlight can be configured to auto-trigger upon detection, serving as a visual deterrent.
