D2 Wireless self-powered door and window sensor

Free Your Hands

Self-Powered by Light + Super Capacitor

No wiring, maintenance-free, flexible installation, energy-saving and eco-friendly, ideal for retrofit projects

Hybrid Light-Powered System

Equipped with a high-efficiency solar panel that harvests indoor light as the primary energy source, combined with a super capacitor and built-in backup battery. Ultra-low power consumption ensures long-term, reliable operation even in low-light or complete darkness.

Flexible Installation & Coverage

Features a replaceable Fresnel lens, allowing for easy adjustment to suit various mounting heights (including high-bay applications) and spatial coverage requirements, enabling precise detection and broad-area monitoring.
