I am in China. Some time ago I purchased DS7000 from the Internet. Ordered the X10 system with 2 door/window sensors, 1 motion detectors, 1 lamp switches, 1 handheld remote, 1 keychain remote and an security system console. Installation was simple and quick. It has been working normaly except Lamp switch. Due to differences in voltage between China and USA. I have to use voltage converters to transform 220V to 110V. For Chinese users, this is a trouble! Why do not you develop a product suitable for the Chinese market?
In China, millions of families do not have the basic security facilities, and wireless security system is easy to install features, will become the preferred home security devices. This is a very broad market, with a very large market potential. Your products are very suitable for ordinary chinese families.
