We have made RF based system already. We are looking at lower cost alternatives. I think I already understand what I need to do. Commercial systems seem to send much higher pulse current so that reflected IR signals also work. I am increasing the current from about 150 mA to 1000-1500 mA now to see if I get the similar effect that cheap commercial remote seem to get. Thanks anyway.
If you don't want to go the RF route, (IMO the best way to go) the best IR remote I have found over the years, is the Xantech URC-2. Very powerful. Don't have to point ''too much''. All hard buttons. Completely customizable. PC Programmable. Back lit. Macros. Old school remote, but reliable. Read the review on RC. You can get a cheap one on ebay, with a little patience.
