This wireless RCA transmitter is a basic model without IR remote control function. It supports one transmitter to multiple receivers, but additional receivers need to be purchased separately. It transmits sound and video signals from the source device to the display. The wireless AV transmitter has a range of up to 300m in clear line of sight, breaking through distance and space limitations. The distance is up to 10-50m when passing through wooden and glass walls, but may be reduced to 10m or less when passing through concrete walls. It supports 5.8GHz ISM band transmission and can be used in point-to-multipoint mode. The built-in 5.8G connection allows the transmitter and receiver to work without a local wifi network, providing clear and stable picture with no noise. The device supports 8 channels and requires the transmitter and receiver to be on the same channel for proper operation. The optimal working channel varies by environment. This plug-and-play device requires no additional settings or drivers. It works with any AV output device including VCD, DVD, IPTV, DVR, satellite receiver, and digital CCTV cameras, enabling wireless signal sharing from living room to bedroom.
