The Blink Video Doorbell is an excellent solution to keep an eye on your home, day or night. This sleek, low-price device features a 1080p resolution camera that records video at 30 fps, so you can see who's at the door no matter what time of day it is. The included infrared night vision mode ensures that you can always keep an eye on things, even in the dark. The two-way talk function also lets you communicate with visitors from anywhere in your home or the world and supports Alexa integration. And if you want to keep any footage for future reference, the Blink Video Doorbell can store the footage on a USB thumb drive or if you choose a subscription plan for cloud storage over your storage. The Blink is powered by two AA batteries that should endure up to two years before requiring a replacement.
