My wife's assets was wiped out a day after our wedding, the only reason why I suspected the hotel we lodged in is because I found two hidden camera in the room the following day of the incident and my wife claimed she revealed her wallet seed because she needed to import her seed into trust wallet from Atomic wallet after we lodged out of the hotel that day all her assets was wiped out, this include 1000 PYR token I got for her as a birthday present months back, I went back to the hotel claiming I forgot a sim card and the room was still empty, here is how I knew the room had hidden camera, could be useful for anyone.
Make sure that everywhere is dark by switching off the light and bring out your smartphone, ON the camera and start waving it around slowly, cameras have something like infrared that flashes light, that light can be detected with your smartphone camera.
You can try this with your smart TV remote too, press a button while your camera is on you will see red light blinking.
Stay safe out there people
Damn! Haven't heard this kind of allegations before. I have been in hotels before with my gf and sometimes even trading and accessing some of my wallets but luckily never robbed just like you man. I don't think this is possible though, these cameras arent that sophisticated I think. Those lil words coming from your phone would be invisible in video by these cameras as their mega pixels count would be low.
