How to Choose the Best Bug Detector 

Battery Life

The battery life of the RF bug detector is significant. Because nobody wants a device, which will stop working within a few hours. So, check the battery life, and if you found detectors that can work for over 12 hours with a single charge, then go for it. (1)

Frequency Range

I think it is better to choose a bug detector, which can cover a broad range of frequency spectrum. Some of the detectors on our list can cover from 1 MHz to 6.5 GHz. But few others can cover up to 8 GHz and 10 GHz. Pick the sensor that covers the spectrum of the devices you want to find. For example, the GPS trackers operate within 824 to 846 MHz or 880 to 920 MHz. Bluetooth bugging gadgets operate between 2.4 GHz to 2.48 GHz. The Wifi communications utilize 2.4 GHz to 2.48 GHz. (2, 3)

Functionality

The bug detecting device has a modest interface and includes a few essential functionalities. For example, when the detecting device found any surveillance appliance then it sends light alerts. Some advanced editions even come with colored strength meters to display and distinguish the signal strength. 

Durability

One most underrated factor is the durability of the device. Most people are likely to carry the device in the backpack, purse, or pocket. Make sure that you buy a device that comes with a durable and sturdy construction so that it won’t break into pieces when you store or carry it. 

Cost

You can find the RF bug detectors at a very cheaper price, but some detectors price is too expensive. On average, most of them are between $50 and $500. So, before purchasing the device, have a look at the functions, accuracy, and other features to know whether it is worth spending some money or not. 

Frequently Asked Questions(FAQs)

What is a Bug Detector? 

A bug detector is generally a portable device that detects surveillance signals. It can be used to contour surveillance systems, such as hidden camera systems, audio bugs, GPS trackers, and more. They help in protecting personal privacy. Besides, the bug detector has other names such as RF detector, hidden camera detector, a signal detector, camera detector, camera finder, and anti-spy detector.

How does a Bug Detector work? 

Wireless devices, such as hidden cameras, networks, and other surveillance systems, work by transmitting radio signals from one setting to another. These signals are Radio Frequency (RF). The bug detector observes the entire space, looking for those RF signals. Once it detects such signals the device sends beep alerts. 

Are Bug Detectors useful? 

Of course, anti-spy detectors are very helpful in protecting one's privacy. Because of the more advanced technology, there are cameras, recorders, trackers, and other privacy decreasing stuff, that are impossible for us to see with our eyes. Be it in confidential meetings, hotel room, lockers, changing rooms, the bug detectors detects every kind of suspicious surveillance and electronic signals. 

Which material is the Bug Detector made from and what is its size? 

To be precise, there is no particular material that is used in making the bug detector. You can mostly find detectors that are prepared from metal, ABS, and plastic. Coming to the size, they differ from one to the other. In general, the bug detectors have a similar shape and size to mobile phones, and they come with a detachable antenna and a flexible ground magnet. 

Which is the Best Bug Detector?

The best bug detectors are those that are in use by high-level authority and military experts. If you need a decent detector choose the model that is certified by some official council. 

Final Thoughts 

Our practical list of RF detectors is best rated and is of top-notch quality. They all can easily detect the radio frequency, that is emitted by hidden cameras, video, data, or tracking electronic devices. Also, the bug detectors are very sensitive to certain frequencies, which most of the spy cams and hidden recorders radiate. Some RF detectors on our list use some kind of meter, while others use an attenuation circuit to detect the location of the bug. Still, we stick to Kunkin kk1 Anti Spy Detector, because it ticks all the categories to be the best bug detector.
