It was most likely designed in 2004 as it looks like the Radio Shack 49-1000 kit. Made for them as an OEM product by X10.
One other thing to note. The DS12A Door/Window sensor. It has an internal reed switch so the magnet and sensor have to be mounted next to each other. For some installations this could be a hindrance and the optional external switch connections maybe needed.
The prices are not that bad. You get more in the $149 kit from X10 than you did in the $149 49-1000 kit from the Shack.
49-1000 kit was console, X10 enabled wall wart power supply, 2 door/window sensors with magnets, 1 motion sensor, 1 keychain remote,mounting hardware packet.
Give it a few months and the prices will most likely drop. Seems most new products from X10 follow that course.
I still have a closeout 49-1000 kit buried somewhere.
