A camera-free motion detection add-on for DoorBird systems. Using 4D radar technology (x, y, z position + velocity), the A8008 detects people approaching your entrance and triggers DoorBird motion events — without capturing any images. Ideal where camera-based motion detection creates privacy concerns or produces too many false triggers from headlights, shadows, or animals.
PoE powered. Ships USA.

Standard motion sensors detect binary presence. The A8008's 4D radar captures x/y/z spatial position plus velocity vector — allowing it to distinguish a person walking toward the door from a car driving past, or someone loitering from someone passing by. Dramatically fewer false alerts.
The A8008 emits radar waves and analyzes reflections. It never captures images. No faces, no license plates, no identifying information — just movement data. For HOA-restricted properties, neighbor-facing entrances, or privacy-sensitive installations, this is the compliant solution.
Radar doesn't need light. The A8008 detects motion identically at 3pm and 3am — no IR illumination, no camera degradation in darkness. Combined with your DoorBird's camera (which activates on trigger), you get motion alerting regardless of lighting.
Rain, fog, snow, and humidity don't interfere with radar wave propagation. Camera-based PIR sensors routinely false-trigger on weather reflections or temperature gradients. The A8008 ignores all of these — reliably detecting only physical movement.
When the A8008 detects approach, it triggers a motion event in your DoorBird system — sending a push notification to the DoorBird app and activating the intercom camera for visual confirmation. The radar detects; the DoorBird records and alerts.
Powered via PoE 802.3af — single Ethernet cable for power and data. Mount it above the entrance or alongside the DoorBird. Connect to the same PoE switch as your DoorBird. No separate power supply required.
