Built for ease of use and installation, WYZE Video Doorbell Pro gives you everything you want without everything you don't. If you don't like screws, no problem, a 3M adhesive strip is included, just peel and stick to any frame. Hate wiring. Us too. That's why we put a massive battery in there that lasts up to 6-months. Never miss anything with an ultra-wide, head-to-toe viewing angle of your front porch in fuller-than-HD resolution. Unlike some companies, WYZE doesn't charge you a subscription fee just to use basic features of your doorbell. What we do offer is Cam Plus that unlocks awesome extra-features like-package Detection, Person Detection, and unlimited video cloud storage. See more than ever before, wire free, with WYZE Video Doorbell Pro.
