Control systems make it possible to bring your electric projection screen into action without the hassle of cranking or pulling, but simply by pressing a convenient button. The screen can be raised and lowered by remote control and stopped at any position. We offer both radio and infrared solutions. The difference between a radio remote control and an IR remote control is that the radio version has a much greater range and can also be used for recessed ceiling screens. With the infrared version, direct visual contact between the transmitter and receiver is necessary.
