The Reolink Pan Tilt Zoom (PTZ) cameras automatically follow movement. That way, you won't miss anything. You receive a movement notification on your smartphone, so you can watch the footage right away in the Reolink app. You can choose between a Reolink PTZ camera with batteries, a plug, or Power over Ethernet (PoE). For example, get a Reolink TrackMix camera that always has power and good internet thanks to PoE.
