Blink Mini 2: was $39 now $29 @ Amazon
The Blink Mini 2 is Blink's new indoor and outdoor security camera. It's weatherproof and comes with several useful features like color night vision, person detection and an easy-to-use companion app. We noted in our Blink Mini 2 review that it didn't have the best sound quality, but if you want a cheap security camera with Alexa integration you can't go wrong here.

However, at this deal for just $48, it's one of the least expensive video doorbells you can find, making it worth a real look for those who are looking to save some money.
