Your Dropcam Pro makes it easy to check in on your house or office, thanks to live video streaming. But how are you supposed to know when to check your feed? That's where Dropcam Tabs come in. These movement sensors talk wirelessly to Pro units, can be stuck to doors, windows, and valuables, and can be configured to give you smart alerts about what's been opened, closed, or moved. They're available in white or black, can be used outside, and are a no-brainer add-on for any Dropcam Pro user.
