Strips is an innovative and discreet door and window sensor for Z-Wave systems. It’s very small, and almost invisible once fitted, so there’s now no need to have so many big and bulky door/window sensors installed. Strips has a built in battery, with a life span of up to 10 years in normal use, so you don’t need to worry about swapping batteries or plugging in micro-USB cables to charge your sensors. Strips is weatherproof, so can be installed on exterior doors/windows.
