Kangaroo offers home security at an affordable price. Their new smart doorbell alerts you when there’s motion- and ring-triggered with HQ Image Capture. It takes the mystery out of knowing who is at the door. Doorbell Camera is powered by 3 AA batteries (included), which when paired with Siren + Keypad have a life expectancy of more than one year! The Siren and Keypad act as the chime when paired but if you don’t have a Kangaroo Siren, you will get app notification when someone is at the door. Best of all – no hard-wiring. With an extra-secure peel-and-stick application, you’ll be up and monitoring in no time.
