The eufy Wall Light Cam S4 is a solar 4K / 8 MP wall light camera with 60 GHz mmWave radar. Power is a detachable solar panel plus a 10,000 mAh battery. eufy’s US page showed 120° radar up to 12 m, color night vision, lighting up to 500 lumens, Google Home and HomeKit (via a hub), and 32 GB eMMC on the camera.

The lamp fires on motion or scenes; eufy says it does not support always-on lighting. The mount needs 2.4 GHz Wi-Fi.

Pros
– A solar 4K / 8 MP wall light cam with 60 GHz mmWave radar and color night vision, powered by a detachable solar panel and a 10,000 mAh battery
– The lamp fires on motion or scenes rather than as a dusk-to-dawn fixture

Cons
– The light does not support always-on lighting, because a constant lamp would drain the pack
– Wi-Fi is 2.4 GHz only, so the mount needs 2.4 GHz at the wall
