Looks like X10 to me. Should work.
FYI: RadioShack has a good "no questions asked" return policy, just don't screwup the packing and manuals, (so they can repack the items).
SO buy 'em, try 'em, and take'em back if they don't work.
BTW: These look like X-10's basic line, there are better modules available, if you want to spend a little more money.
