This easy-to-install security camera allows you to observe and communicate with whoever is at your door. It sends alerts to your phone when it detects motion and has infrared night vision so you can see in the dark. Best of all? There's no wiring; it operates up to a year on a rechargeable battery. Or you can plug it into a dedicated solar panel ($49) and forget all about recharging. $199; Ring
