Built for ease of use and installation, 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. That’s why we put a massive battery in there that lasts up to 6 months. Never miss anything with an ultrawide, head-to-toe viewing angle of your front porch in fuller-than-HD resolution. 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 Video Doorbell Pro. Hassle-Free: Effortlessly mount Wireless Doorbell Pro for front porch protection in under 30 seconds. Screws and hardwiring equipment, though optional, are included, for even more ways to install. See the whole story – clearly: A 1440×1440 fuller than HD sensor means you’ll see it all with 33% more clarity than traditional HD cameras. Chime Included: Hear your doorbell ring, chirp, or bark. Choose between 20 unique tunes and 8 sound levels to find the perfect chime for you, even scare off potential intruders with a dog bark. Optional upgrade available: upgrade to Cam Plus to receive real-time alerts when people are detected and store full-length videos in the cloud for 14-days.
