List of the 10 Best Bug Detectors

1. Spy-MAX Law-Grade ProMax GPS Tracker Buster & Detector

Best Bug Detectors

This is a basic multi-bug detecting device. It comes in retro style finish and will be rather unassuming as it looks like an old piece of technology. It weighs only 10 ounces.

This means that you do not need to worry about anyone tracking your mobile device. It can also detect GPS trackers. All GPS trackers use a cellular signal in order for them to transmit the coordinates of the GPS tracker. As the signal strength of the cellular signal weakens, the cell site will initiate registration on its own by sending a signal to the tracker, causing the tracker to transmit and identify itself. This device can then check for such wireless signals and immediately alert you if such a signal is present.

It has an LED display panel. This LED display panel is made up of many individual LEDs. When you get close to the bug, more LEDs light up. When all of them light up, this shows that you are at the point where the bug is. In addition to LEDs, the device also vibrates and gives out a beep sound. This feature is very handy in cases where you have very bright light levels which may make it difficult to see the LEDs. It has a retractable antennas. You can easily pull back the antennae when the device is not in use. This prevents damage to the antennas. It is powered by 4 AAA batteries that come included in the packaging. These batteries are very easy to find and replace. This device has the main drawback that it is a bit pricey. Due to all these factors, we have chosen this as the best bug detector.

How Much Does a Bug Detector Cost?

Bug detectors are not very cheap devices. These devices can easily get you off budget if you buy them without budgeting for them. They can be found in the 50 – 350 USD range. The high end devices are near the 350 dollar mark. These devices come with advanced features such as the ability to detect 2G, 3G and 4G SIM trackers. They also usually have the ability to give you a sound and vibration alert. An example is the Spy-MAX Law-Grade ProMax GPS Tracker Buster & Detector.

The midrange bug detectors are in the 100-200 USD range. These devices have similar features as the high end devices but may come with a few drawbacks. An example is the lack of a rechargeable battery. An example is the Acousticom 2 200MHz – 8GHz RF Detector.

The low end devices are in the sub 100 USD range. These devices are made by lesser known manufacturers. They are usually more geared towards technical people than the general public. An example is the sherry Anti Spy Detector & Camera Finder.

Types of Bug Detectors

Laser Lens Detection Bug Detectors

Some surveillance devices may not transmit signals at all. These make it impossible to find the device using an ordinary RF bug detector. An example is a hidden camera that records videos to a micro SD card. In this case, you will need to use a hidden camera lens detector. These types of bug detectors are able to detect the lens of the hidden cameras.

Non-Laser Lens Detection Bug Detectors

These are the traditional bug detectors. They are not able to detect hidden cameras. If a hidden camera is present which records the videos to a micro SD card, then you will not be able to detect it.

Why Do You Need a Bug Detector?

Safety

You never know who is watching you. It is possible for people to take videos of you undressed, and then use them for black mail. Such issues are very common in public changing rooms as unscrupulous individuals take advantage of unsuspecting women and use their naked pictures and videos for blackmail. Using a bug detector prevents against such situations.

Privacy

There are times when you do not want anyone to know where you are. It is impossible to have such privacy without you knowing if there are any bugs in your vehicle. In such cases, a bug detector will do wonders.

Crime

Unscrupulous individuals can use the video footage for crime. For example, if a thief puts a secret camera in your home then he or she will be able to know when you are at home and when you are not at home. He or she can then break into your home when he or she knows that there is no one at home.

Factors to Consider When Purchasing a Bug Detector

Frequency Range

A bug detector works by identifying the radio signals emitted by the bug that is present. You will need a device that covers the most frequencies in order for it to detect the most amount of bugs. A device that operates in the 1 MHz to 10GHz range must operate pretty well for any typical application.

Reviews

Have a look at the reviews to see if the bug detector actually work. Check the product that has the most favorable reviews and select that one.

Filters

Radio Frequency signals are everywhere. Your mobile phone receives RF signals from cell towers. Your radio receives RF signals from radio stations. You need a device that is able to filter out any ambient signals to prevent it from giving you false positives.

Warranty

Bug detectors are expensive devices. You certainly do not want to buy a bug detector and have it fall apart after a week of use. The warranty gives a good indication of the manufacturer’s confidence in his or her product. As a general rule of the thumb, the bug detectors with longer warranties are made from better materials and last much longer than similar products that have shorter warranties.

What is a Bug Detector?

A bug detector is an electronic device that is capable of detecting hidden hardware spying devices through the use of RF signal detection and lasers.

How Do Bug Detectors Work?

Hidden hardware spying devices usually give off RF signals. These devices could be any of the following: hidden cameras, hidden audio devices, GPS devices and SIM card tracking tools. These devices usually give off radio frequency signals. These signals are then received by the receiving equipment that the person who is spying on you uses to get the information. Bug detectors are able to detect the presence of these radio frequency signals. The radio frequency signals get stronger as you get closer to the source. The bug detectors use this property to allow you to know the exact location where the bug is. If you have a hidden camera that does not give off radio signals e.g. a hidden camera that saves files to an SD card, then you can use the laser LEDs to identify the hidden lens.

Bug Detector FAQs

Can This Device Scramble Signals?

No. Scrambling signals is illegal anyways.

Does This Device Block GPS Signals?

No. All the bug detectors can do is tell you that there is a bug present.

Can This Detect Bluetooth Connected Cameras and Microphones?

Oh yes. Bug detectors can most certainly detect these devices.

Can I Travel With This On An Airplane?

Yes. When the airport security asks what it is, tell them exactly what it is and that you would like to travel with it. Make sure to turn it off as it may make the ride rather noisy.

Are Bug Detectors Heavy?

Most of them are not. They are usually designed to be portable.
