Measy RCA220 is a $35 Wireless AV Transmitter / Receiver Kit with a 200m Range

Orange Pi Development Boards

There are several ways to send video & audio data over a distance without using long cables, from professional DVB-T transmitters with up to 10km range, to cheaper DIY SDR solutions with a shorter range , and HDMI transmitters leveraging your existing electrical cables.

Those all work for different target applications (drones, video signal extender), but cost at least a few hundred dollars. If you just intend to transmit composite video (PAL/NTSC) and audio within a house or building, Measy RCA220 will be a more cost effective solution with a range of up to 200 meters.

Measy RCA220 AV transmitter / receiver specifications:

  • Connectivity – 2.4GHz wireless transmission with up to 200m range; built-in antenna, 8x selectable channels
  • Video / Audio Ports
    • Transmitter – RCA composite input, 2x RCA L/R audio input
    • Receiver – RCA composite output, 2x RCA L/R audio output
  • Misc – IR jack, channel selection button, front panel display, on/off button
  • Power Supply – 5V/1A via micro USB port
  • Dimensions – 10 x 10 x 2.5 cm (aluminum enclosure)
  • Weight – 280 grams

The kit includes a transmitter, a receiver, two power adapters, two AV cables, two wall mounts, and a bag of screws.

There’s no software required, just connected the AV cables to your input device (e.g. STB, CCTV camera…), and output device (TV / monitor), the power supplies, and select the same channel for both the receiver and transmitter, and you’re good to go.

I  found Measy RCA220 on GearBest for $34.94, but eventually it should be sold on other websites too, and Aliexpress has similar kits for under $40.

People still use composite video? These used to be available just about anywhere at one point for people wanting a bedroom TV, but didn’t have an antenna socket in the bedroom. I know I had one, my old man had one and they didn’t cost this much.

Yeah, devices like these were useful before WiFi took over 2.4GHz, but now? Using one of these in a populated area is sociopathic.
