Often you read terms like “RF signal”, “RF”, “frequencies” and you wonder what does it mean and how does it work. More importantly, what you need to know about them when you’re ordering a spy device like spy bug or wireless mini spy camera. Let’s take a quick look.

Radio frequency or RF is electromagnetic waves that allow for wireless communication. There are all sorts of waves around us. Sound wave is the one you can hear. But there are many you can’t see or hear or feel, such as ultraviolet radiation, infrared, electromagnetic or radio waves. Simple TV antenna works by transmitting signals to communicate with a station and let you see the channels of your choice. TV’s, cell phones, wireless cameras – all operate under radio frequencies. RF can differ. Most common is 2.4 GHz frequency. Most devices operate at this frequency.

Wireless camera detectors work by capturing the radio frequencies transmitted. They can channel in to the specific frequency and let you view or hear what spy camera sees and records. Bug detectors also work by using radio waves. They detect any devices that produce frequencies. Therefore it’s advisable to turn off cell phones, microwaves, TV’s when searching for bugs in a room as they’ll interfere with the bug signal if there is one.

To make things more interesting, some bugs, spy cameras are designed to work at unusual frequency range, thus undetectable by regular bug sweepers. However, more advanced detectors allow for radio frequency scanning at different spectrum.
