Title is misleading. It only detects RF. A hidden camera could record to storage for later upload in which case wouldn’t be transmitting continuously.

- satori99 2y agoWhat you really need is a Non-Linear Junction Detector. These can detect an unshielded device with transistors, even if it's off. https://en.wikipedia.org/wiki/Nonlinear_junction_detector https://en.wikipedia.org/wiki/Nonlinear_junction_detector
- killingtime74 2y agoThat would only be practically useful in an environment devoid of all other electronics. How would one tell between the non-transmitting spy cam and normal household electronics
- KeplerBoy 2y agoBy having some spatial/angular resolution. You'd need a large directional antenna or multiple antennas to have something similar to a phased array radar, but passively (i.e. listening only).
