How to Use a Bug Detector?

What is an RF detector? It is a tool that can detect radio frequency signals. You must turn on the device and walk around the room, detecting those places where the frequency or signal is higher, as denoted by a light or a ringing noise.

Below we mentioned the necessary steps to use a bug detector in detail.

What you will need to follow this tutorial

Performing this procedure does not require many tools. People should have the following:

  • Bug detector
  • Camera attachment to detect hidden cameras
  • Electronic devices are turned off.

Step-by-step instructions

The following steps must be performed to use a bug detector properly.

  • Switch off wireless networks or electronic devices.
  • Switch on and prepare the bug detector 
  • Perform a walkthrough of the entire room
  • Attach the hidden camera attachment
  • Remove the spy device

1. Turn off wireless networks or electronic devices

These devices have the same characteristics: they are connected through a network over the air. It can be more than enough for interference, which is why other devices, such as conventional telephones, are not included. You should turn off each of these devices when performing this procedure.


2. Switch on and prepare the bug detector 

Some devices may incorporate straightforward functionality that does not require any prior configuration. Sometimes a bug detector can be combined with a hidden camera accessory. This accessory should be included if the user wants to detect hidden cameras in a room.

Some wireless networks or signals could interfere with a bug detector’s proper functioning. These not only interfere with this device but can also cause false-positive alerts. Specifically included are the following devices:

  • Routers or devices with wi-fi.
  • Devices with Bluetooth turned on.
  • Phone calls from cellular phones
  • Phone calls from cordless phones

This part should not be used when locating any spy device. It could provide errors and inaccurate results. 

Most bug detectors incorporate an antenna that should be extended as far as possible. It is enough to press the power button and display the LED lights that indicate the detected signal’s strength. (1)

3. Perform a tour of the entire room

Performing the walkthrough may require patience at the beginning to avoid committing to the same task twice. The bug detector works similarly to a metal detector. This device’s signal will become stronger as the user gets closer to the spy device they wish to detect. (2)

It can provide an audible or visual signal through some lights incorporated into its structure. The user should pay attention to this factor at all times. 

An excellent way to find the exact location is to move closer and further away from the possible places where the spy device is hidden. It would be best to consider some familiar places chosen to hide a spy device. Some of these places are as follows.

  • Plants or flower pots
  • Alarm clocks
  • Mirrors or glass
  • Windows
  • Everyday decorative objects
  • Books or libraries
  • A closet full of clothes
  • Top of a door
  • Pens
  • Portraits or decorative pictures

4. Attach the hidden camera accessory


When finding a hidden camera, it is necessary to use the intended accessory. Not all bug detectors include this accessory. The LED lights incorporated should be pointed toward the user. It is the equivalent of the bug detector’s LED lights, which are used to indicate the signal.

The red part for finding hidden cameras should be pointed toward the suspicious spaces. Since a hidden camera is a tiny object, every single area in a room must be considered. It should be aimed at light fixtures, ceiling corners, mirrors, everyday objects, pillows, and other familiar places.

A very prominent red dot will be visible when the user points to the right place. It clearly and precisely indicates where the spy camera is located. This procedure requires some practice depending on the models and the ease of bug detectors.

5. Remove the spy device

To stop a spy camera, turn off the power supply. The power source can come from a power outlet or a battery.

It means the user only needs to unplug the device when it is a spy watch or similar object. Removing the battery will also be enough to prevent the spy device from operating. It is unnecessary to destroy the device, as removing the power supply is sufficient.
