Jusubb Hidden Camera Detectors, Camera Detector, Bug and Hidden Camera Detector, RF Wireless Signal Scanner for Home Office Travel, 6 Levels Sensitivity 4 Modes, 32H Working Time

Just got this today and have played with it some. Seems to work well on the camera detection, it does work better in darker room, light is ok but I would close blinds or curtains during the day. Detecting signals it is not something you walk through and instantly find them. It will let you know when you are close and then you change to a higher sensitivity and sweep that area more thoroughly. For a hotel room, small office it would be quick. The Magnetic field detector I have not been able to get this to work yet although that could be on me? Overall if you travel a lot and stay in hotels this might be a good piece of mind when worried about cameras without spending a fortune and that is why I bought it.
