What is a RF Bug?

A Radio Frequency or electronic bug is commonly used for acquiring secret information. A bug is a combination of a radio transmitter and a microphone or video camera. The microphone or video camera listens to and records sensitive conversations while the radio transmitter sends that information out. RF detectors are able to ‘catch’ the transmitted signal.

Bugging can be performed through a variety of devices such as mobile phones, hidden cameras, Wi-Fi routers, and Bluetooth devices, etc. An RF bug detector can accurately sense these devices and protect your privacy to give you a more secure environment.

Our Research Methodology

We surveyed a wide range of RF bug detectors. The main criteria we selected for choosing our top pick are frequency range, accuracy, ease of use, cost, and battery life.

Frequency Range

A bug is detected by the virtue of its emitted frequency. A good bug detector must be able to pick up a wide range of frequencies.


The accuracy of the RF detector is dependent upon its sensitivity and dynamic range of the electronics. A good RF detector must be able to detect the faintest signal being emitted amidst strong ones.

Ease of use

Ease of use, and portability is one of the key points for the selection of any RF detector. The user must be able to easily use the instrument.


Cost is a big one obviously and it determines accessibility.

Battery life

Long battery life is extremely helpful in assignments in challenging environments that might take longer and emergencies as well.


We recommend testing the product you purchase within the 30 day return window to ensure that it meets your requirements. One way to test a product is to see if it detects known transmitters. Examples are your cell phone, Ring device, etc.


Unwanted surveillance is now becoming a constant threat to people. Sensitive areas such as hotels, offices, dressing rooms and Airbnbs can be easily bugged with cheap surveillance devices. It is important to protect yourself from unwanted spying and eavesdropping to ensure your privacy. We have surveyed and studied many different products and we offer you our recommendations for the best instrument.
