Start safeguarding your home by monitoring it in real-time with this Philips Hue Secure starter kit. The smart home security system comes with three Secure contact sensors in white, one indoor motion sensor, two White and color ambiance E26 bulbs, and a Bridge. Give yourself peace of mind both home and away by letting the Secure contact sensor provide your doors, windows, cabinets, safes, and more, with an extra layer of security.
