Sensors in the home ... mass market?

My home is instrumented with over 30 sensors. These provide information on temperature, movement, doors & windows, alarms (such as smoke), and visual information through lamps and cameras. Some also measure power consumption and allow control of electrical devices. They all connect to a central hub controller using the ZigBee wireless standard, and are completely user installable by non-technical people very easily. The hub self organises and configures the network as you add more components to the system. Batteries in the smallest sensors generally last about a year. The hub has battery backup from mains and also a GSM data SIM if the ethernet connected broadband should fail. The system is managed / configured through a web browser on any computer operating system or via an iPhone/iPad app. The system can use the same set of sensors and other components to provide a number of services including security, energy monitoring and home automation.

The user installable aspect and ease of retro-fitting are the main reasons why this system (AlertMe) has the potential to be mass-market. However I believe this will only happen when the product is available and showcased in home improvement stores (such as B&Q and HomeBase in the UK, and equivalent others across the globe). The fact that it can be fitted in a matter of minutes by almost anyone, and is as simple as un-boxing it and inserting batteries and then fixing the sensors with sticky pads, means that it needs to be on the shelves of retail stores nationwide in order for this innovation to have a bigger impact on the marketplace.
