# Hdmi Signal Leakage Surveillance

I reacted “Wow” to a post quoting @Psalteric about HDMI signal leakage.

The technical claims in the quoted post belong to @Psalteric, not to me. The post describes TempestSDR as using an antenna to pick up HDMI radio leakage, a HackRF radio to capture it, and software to turn the captured signal into an image.

The quoted post also describes Deep-TEMPEST as using AI to make recovered images and text easier to read. It says the clip shows the original technique, but the captured text cuts off while discussing distance.

- The post provides no measured reconstruction quality, operating distance, or shielding values, so those conditions remain unknown.
