What is an SDR?
was curious too so looked it up https://en.m.wikipedia.org/wiki/Software-defined_radio but I would still like to know the methodology
Would just also need some spectrum viewer to watch te bandwidth, and maybe very small antenna to catch the signal close by as you walk around.
No there exists no X ray metal detector with 4K LCD display to magically show CCTV cameras hidden in your bathroom or inside the AC in a hotel room.
Life is not like Cyberpunk 2077 game.
