   It doesn't detect short burst well at all. It does detect traffic over a second or so, like a TCP session of an h264 stream. https://www.amazon.com/dp/B07FHZXTCZ?ref=ppx_yo2ov_dt_b_fed_... Specifications: Working

   You know, when my wife opens up a webrowser on her phone and it starts transmitting this device triggers. When I go next to a wifi camera and it picks up the RF, it triggers. Demonstrably it does detect signals. You clearly don't unde

   I would think it would work really well for that usage case. You could tune the antenna to focus on the in use bands. The automatic baselining solves a lot of this.

   You could without boost converter and the battery. https://x.com/rogerscissp/status/1847430193113141549/photo/1

   It baselines on power on. So you'll need to get closer to raise the baseline. It also doesn't seem to alert on beaconing (or very little), my wifes phone and other devices need an active transfer to trigger it. (more than a 1&#x

   I found someone with a pen recording me. They left it on the desk, and I took it by mistake. I found it in my kit and realized it was a spy device.... yikes.

    Only if it’s transmitting, this detects rf. It can’t detect ears.

    It doesn’t say “all”, it also doesn’t detect a someone in the closet, unless they’re transmitting.

    This is dependent on the antenna. With a short 915 mhz antenna it picks up stuff 50 feet away. It auto calibrates on boot so if you’re in the woods I bet it would work really well. Just make sure you turn it on without a strong nearby signa

    This Device lights up pretty good on wireless or cellular data transfer. If my wife starts browsing on her phone it lights up.

    Well, maybe - it would need to have ir enabled. This also detects listening devices etc.

    Thanks, it costs about 30$ in parts. Not sure what a fair price would be.

    It runs the screen and reads the sensors, you can see it in the code.
