An RF detector or radiofrequency detector is one of the most widely used tools to combat spy and surveillance bugs. It is a tool that can be used by both amateurs and professionals.

You may want to check the list of the best bug detector and the DIY bug detector instructions that will surely help you!

What exactly is an RF Detector?

An RF detector is a tool that allows you to monitor and sample the output of a radio frequency circuit. It is possible to emit a DC output voltage. This voltage is usually proportional to the power at that point. A radio frequency detector makes it possible to detect electronic devices in your home. (1)

Devices with wireless operation usually emit radiofrequency. The RF detector allows you to measure and see the power of these wireless devices. An RF detector is used to be able to detect the presence of spy devices in the home.

What is an RF Detector used for?

When a person suspects that his home has a small camera or a small microphone then he requires some tools. Some microphones and cameras are too small to spy on other people. A radio frequency detector is one of the best tools to detect these small devices or bugs.

A radio frequency detector allows us to scan and check a whole room. The radiofrequency detector will emit some kind of sound signal when an electromagnetic field has been detected. This signal tells the user that it is very likely that his home has a spy camera or a spy microphone. (2)

The signal can intensify as the user gets closer to the location of the spy device. This is widely used to know the exact location of the spy device and destroy it for good. The graphic indicators of the RF detector are intensified as well as the sound signal.

Most radiofrequency detectors require the workmanship of a professional. Some of these tools are too complex to be used by a beginner. Some professionals offer their services to detect all types of spy devices in a home.

This type of tool can also provide the possibility of detecting cell phones as well as any spy device found in a home.

Some basic procedures allow a person to create their radio frequency detection tool. Amateur electronics users can build their tools and detect the presence of any spy device.

Final Words

A radio frequency detector can be the best companion for a person who suspects spying devices in his home. After using this tool or hiring a professional with this tool, any home will be bug-free (may depend on the quality of your tool). That is why it is important to learn how this tool works to use it to your advantage. One thing you should also consider is having an application that would help you test if your bug detector works just fine, but, one question that we will try to answer with this learning guide we’ve made is do bug detector apps work? Find out the answer! Til’ next time!
