Review on Hidden Camera, RF Detector & Signal Finder by Michael Hale

I wasn't expecting much for the price but I was very happy with the result. I was able to see every wireless signal in my house and every wireless camera I had. I haven't tested my wired cameras because they're high above the house, so I don't know if they'll detect them. The device is very light and although it seems cheap, it works well. The instructions are simple. Just plug in your USB charger and charge before use. As you raise and lower the antenna, it adjusts its sensitivity. Although it didn't detect anything in the middle of the room, it started blinking (beeping) when I got to my router or wireless camera, and the signal got stronger the closer I got. It would be great if you could walk across the room and approach the vents. I'm sure you'll spot hidden cameras/wireless signals.
