You set one up, and it sends a short low-framerate video (basically a 2-second animated gif) to your phone when someone rings it or it senses movement. They’re battery powered (with 3 AAs included), so there’s no wiring or complicated installation. Those AAs should last a few months. If you swap in some premium alkalines, even better. Also, each camera comes with a chime box. That means, if someone presses the button on the main unit, the box will ring. Which is kinda like… wait, what is that thing called? Oh, right! A doorbell!
