Just as a fence is only as strong as its weakest link, many home security systems can be easily toppled by a door or window left ajar. The LILA system (Leave it Locked, Always) from QL London is designed to make sure that anytime homeowners leave the home, they receive alerts for any unsafely open ports of entry. A self-adhesive sensor can be placed on any doors and windows and will communicate via Bluetooth to the LILA Hub and/or the LILA App if it detects that the an entryway is left open. For £12, a 2-pack of sensors can be delivered (add £7 for shipping outside the UK), making homes safer in September 2014.
