If you’re using Blink home security cameras—particularly the Blink Outdoor 4—you need this gadget on your network.

Blink Indoor Camera The Blink Indoor Camera features a wireless design when paired with the included sync module. It delivers two-year battery life, HD resolution, motion detection, and two-way audio.

My bottom-line score, therefore, is from the perspective of a Blink camera owner who doesn’t want to pay for a subscription and who doesn’t own a previous-generation Sync Module.
