Bought this a year ago and haven’t been able to use it due to apartment living and lack of an accessible modem (you need a modem to plug it in to initially set up the home base!) The camera is waterproof and can be used outdoors or indoors. The two sensors can be used on windows or doors. Love eufy because you don’t have to pay for a subscription since the home base stores everything local. Never opened- bought off of eufy’s website and still have the receipt. I bought this same setup for my parents and they love it- from their experience the camera battery life lasts a few months at a time before needing to be charged. Feel free to make me an offer- I’d just like this to go to someone who will actually be able to use it!!
