GET A QUOTEWindow intercom systemDG-800 system uses UHF frequency band to transmit signals, which can prevent wireless microphones from being blocked by signals or being interfered by signals of other frequencies. The automatic frequency adjustment device receiver with patented technology automatically scans the entire receiving frequency band, and automatically adjusts to the outside world. The disturbed frequency, and then use the infrared transmission method to send the frequency setting parameters to the transmitter, so that the transmitter will lock according to the frequency set by the receiver. the
