After looking at a lot of hidden cameras, microphones, and other spy gear, it’s time to look at some methods of prevention. Being equipped with bug detectors is crucial to preventing intruders from breaching your privacy in any way. Whether it’s recording video of your home, recording your voice, or any other type of spying method – it is important to fail every attempt aimed at entering your personal privacy!
The good news is that there are various ways to detect hidden spy devices of any type. Most of the spy devices utilize some form of wireless connection to transmit information. Even if they record on-device, they give out a signal like Infrared, Bluetooth, WiFi, Cellular, etc.
The bug detectors I reviewed in this guide work great for detecting these signals, which will enable you to catch a spy device of any kind.
Things to Consider Before Buying A Bug Detector
A bug detector is not only available for law or military counter-intelligence personnel. You might need them too. Especially if you are expecting unwanted surveillance threats. People of all kinds, with malicious intentions, can use a range of surveillance devices to keep an eye on you or to record or live-stream what you are doing and saying secretly. We hear about many cases of tiny hidden cameras that were found in places like Airbnb rentals, gym locker rooms, or even public bathrooms.
Making use of an RF bug detector becomes a basic safety measure to keep your privacy to you.
Bugs and Devices You Can Detect with a Bug Detector
Hidden cameras, also known as spy cams, are often placed sneakily in hotel rooms, changing rooms, and gym locker rooms to record and live-stream your activity. These covert devices are cleverly embedded in otherwise innocuous-looking items like alarm clocks, phone chargers, smoke detectors, and even shampoo bottles.
The smallest hidden camera was once found inside the cross of a Phillips-screw head, which is almost invisible to a naked eye.
Most hidden spy camera detectors work by detecting the pinhole lens of a spy cam. Handheld detectors look for the prevalent radio frequencies by conducting an RF scan. Spy camera detecting apps work by scanning suspicious devices connected to Bluetooth, Wi-Fi, and local networks.
The following audio bugs are commonly used. Luckily these devices are detectable too by RF bug detectors. Let’s discover the different audio bugs we can be dealing with.
- GSM bugs: A GSM bug is a wireless listening device that is fitted with a SIM card using a 3G/4G GSM network. The intruder can access and control it from anywhere through a telephone call. GSM bugs can be hidden in electronic accessories, lamps, products, and other commonly used appliances. Since they are hidden, they are very compact with a simple design. They can hear from a distance of 30-50ft. Further, as they are powered up by a GSM network, they can also track your location.
- Miniature voice recorders: Miniature voice recorders are mini recording devices that are disguised as everyday objects like USB drives or credit cards. They hide themselves well and are capable of recording high-quality audio.
- Wiretaps: Wiretaps are installed on the telephone system to intercept telephone conversations. Thus, this audio bug gets activated only when the all is active.
- Mobile phones: Mobile phones also work as an audio bug. The phone is programmed not to vibrate, ring, or show any signs that you are being called. The spy can then call your phone, which gets auto-answered and can listen to your conversation.
GPS Tracking Devices
A GPS tracking device makes use of the Global Positioning System (GPS). GPS is a worldwide radio-navigation system comprising the constellation of 24 satellites and ground stations. A GPS tracking device can be fixed or a portable unit. For instance, your company might use a GPS tracking device to track your route and progress.
If you suspect that you or your vehicle is being tracked by a small and undetectable GPS tracker, a GPS detector is what you need. A GPS bug detector works by detecting the radio frequency signal sent by a GPS tracker to the cellular networks to communicate status and location with.
So, if you want to keep yourself safe from any of these bugs and hidden spying devices, it makes very well sense to use a bug detector.
How A Bug Detector Works
In simple terms, a bug detector is a radio receiver. It works on the principle that a surveillance device emits electromagnetic signals. A bug detector detects these signals, and this is how it tells you if there are such devices nearby.
More often than not, hidden cameras and audio bugging devices transmit WiFi, cellular, or Bluetooth signals. However, they may utilize different radio frequencies depending on how the whole arrangement is set up. An audio bugging device, for instance, set up on a cell phone, may transmit a cellular signal, and so on.
Thus, it is recommended to choose a bug detector that is capable of detecting signals belonging to a wide range of frequency levels.

Bug Detectors Buying Guide
Here are a few key components in selecting a bug detector that best suits your needs.
Features of Good Detector
You should think about exactly what you need. Are you trying to find some microphone bugs in your house? Are you afraid someone is eavesdropping on you with a camera? Or maybe your phone is tapped. Surely, the first thing you should think about is how you can be spied on and what to suspect in the area you are. Next, you can count the following things as the most important aspects to consider when buying a bug detector.
The battery life of a bug detector is important. You don’t want to end up with something that dies within hours of charging it up. Look for a detector that can work for at least 12 hours without requiring you to charge in between. This will come in handy if you commute or travel frequently and need to rule out any privacy errors.
As I mentioned above, choose a bug detector which covers a wide range of frequency spectrum. Most GPS bugging devices operate within 824 – 846 MHz and 880 – 920 MHz. Bluetooth bugging devices utilize 2400 – 2480 MHz, and WiFi transmissions happen at 2400 – 2480 MHz. Pick a bug detector according to which bugs you want to go for.
Durability is another important factor while choosing a bug detector. Most likely, you will carry the device in your pockets and bags. Ensure that it is sturdy in construction so that it doesn’t break off easily.
Most bug detectors do not come with a lot of bells and whistles. They have a simple interface and support a few basic functionalities. For instance, they will light up when they detect any signal in space. Thus, you will have to conduct a physical check to identify the installed surveillance device.
A few more advanced versions even include strength meters to give you an idea of how strong these signals are. These detectors with basic functionalities can be easily found for less than $300 in the market.
If you go up the range, you can find a bit more advanced bug detectors, which in addition to helping you find the tracking device, also help you in blocking the signals. They may also provide you with a better picture of signals, thus helping you judge if you are looking for a device in the right direction.
Ease of Use
It’s important to be aware of how much effort you are willing to put into bug detection and spy protection. A lot of the bug detectors are very sophisticated hardware. Often, you will have to figure out how to use some advanced gear. A smartphone app could be easy to use. However, those are not a good substitute for a proper bug detection device.
You can find bug detectors for as low as $30, and the range could go high with no limits. On average, most bug detectors are priced between $50 and $500, depending on the type of features, their frequency range, and the accuracy they offer.
