It's more likely to be an artificial light source interfering with
the IR. I've heard fluorescent light is especially bad. Try turning
off your lights and trying the IR. If there's more than 1 light on
normally, turn them on one at a time until it stops working to find
your culprit. Unfortunately the solutions really are to not use the
light causing the problem or move the receiver and transmitter closer
to each other until they work.
