UniFi G3 Flex

Quick verdict

The G3 Flex is a small, cheap PoE camera that records locally on UniFi Protect and integrates with Home Assistant via the UniFi Protect integration or generic RTSP, with no subscription. It is an older 1080p model with no on-device AI detections, so it is best as affordable extra coverage for UniFi households rather than your main camera.

Standout: Compact, affordable PoE camera with fully local UniFi Protect recording.
