QR Code Link to This Post
Fully assembled, working AI camera turret that detects and physically tracks objects in real time. On-device neural inference runs on a Google Coral Edge TPU — no cloud, no subscription. A motorized pan-tilt mount follows the target while a live video feed streams to any browser on your network, with auto-tracking and manual aiming modes plus onboard illumination for low-light use.
Hardware:
Compute: Raspberry Pi 4B (64-bit, Raspberry Pi OS Bookworm) 4GB RAM
AI accelerator: Google Coral USB Accelerator (Edge TPU) for real-time inference (~30 FPS on SSD MobileNet V2, 80 COCO object classes)
Motion: Pimoroni Pan-Tilt HAT, dual servos, ~180° pan and tilt
Camera: Raspberry Pi NoIR Camera (IMX219, 8MP) — no IR filter, suited to low-light/night use
Lighting: 18-LED GRBW addressable strip (status indication + white illumination), camera-mounted
Storage: 32gb SanDisk microSD with OS and software preloaded
Power: Official Raspberry Pi USB-C supply included
