very good product! The official DC power supply is from 12v to 24v, it can be with a minimum of 8 or 9v for the receiver and for the transmitter depends on the distance: for the 150m model, I mounted it 20m from the receiver the minimum is 3.6v for good accuracy. I mounted a 5v power supply. it may increase the life of the ir leds
simply and good
