Anker today launched the Eufy TrackLight Cam S1, which it says is the world's first outdoor security camera with an auto-tracking light for actively deterring intruders. The TrackLight Cam S1 is compatible with Apple Home when using the Anker HomeBase, so it can be used alongside other smart home devices in a HomeKit setup. When a suspicious person is detected, the camera locks on and follows them with a light from up to 12 meters (40 feet) away.
