Building a wireless HDMI video monitoring solution using WHDI technology

15 years old. Gear and prices may have changed since.

What the thread found

  • WHDI wireless HDMI transmission can deliver uncompressed video with zero latency
  • A WHDI dongle powered through USB can be configured to output both HDMI and HD-SDI simultaneously
  • The advertised range for this WHDI implementation is 23 feet when obstructed
  • WHDI signal can penetrate multiple walls without significant loss
  • Enclosing WHDI equipment in a sealed pelican case degrades signal strength
  • HDMI protocol generally does not support PSF video signals

Depends on

  • Testing was limited to one camera model at the time of the discussion
  • The original prototype unit failed during early development and required replacement
  • Range testing was incomplete and mostly theoretical based on manufacturer specifications
  • One user reported compatibility issues with PSF output from their particular camera setup
