Review on Hidden Camera, RF Detector & Signal Finder by Mark Quarterman

I loved this detector. It works almost exactly like a metal detector. You set the sensitivity of an extremely broadband receiver, and then when you approach an RF source it will flash and/or buzz. If you suspect there is a bug or streaming device hiding in your office or hotel room, it's very simple. find him. It also points to common RF sources like the Wi-Fi router and other Wi-Fi devices in the home, including the Revain Echo. It needs to be turned off in an area covered by Wi-Fi, but it will still do its job. It also detects Bluetooth devices and walkie-talkies, as well as cell phones. It would be very helpful when traveling to Pyongyang, North Korea. This device makes it clear how much RF radiation we are exposed to in the office or at home. All in all, this is a very useful tool and well worth the money.
