Best RF Detector – 2019

Everything You Need to Know When Shopping for the Best RF Detector Buyers Guide and Reviews

Technology has become incredibly sophisticated.

Years ago, having a computer with access to the internet in your home was considered a luxury. These days, hardly anyone leaves home without the computing powerhouse known as the smartphone in their pocket.

These many technological advancements have allowed us to connect faster with one another. Unfortunately, those advancements have also made it possible for nefarious individuals to intrude upon private lives without their victims even knowing anything is wrong.

To ensure that your private life remains that way, you need the right tools to protect yourself. Among the tools you will need is the device known as an RF detector.

In this article, we will learn more about the purpose of the RF detector and how one variant of this device can differ from another. We will also look at some of the top RF detectors that are currently on the market to see if they can work well for you.

What Is an RF Detector?

Before we go any further, let’s first discuss what an RF detector actually is.

An RF detector is a bug detector. We’re not talking about those bugs that crawl around on many legs though. Instead, we’re talking about the bugs that can be used to spy on you.

Bad actors may use a variety of electronic bugs, implant them in your home, your office, or even your car and immediately become aware of your activities.

A good RF detector will be able to sniff those bugs out by honing in on the radio frequency signals that they may be producing. An individual interested in spying on you may be able to expertly hide their bugs, but they won’t be able to conceal the signals they produce.

If the electronic bug in question is active, your RF detector will be able to tell you how close you are to it. By focusing on the signal and seeing when it strengthens, you should be able to find the bug’s precise location and eventually remove it.


What Bugs Can the RF Detector Spot?

There are six types of bugs that you will be able to find using an RF detector.

The first type of bug that you may find is known as the standard RF transmitter bug. You don’t need to spend too much time trying to locate standard RF transmitter bugs because they continually produce RF signals.

Burst bugs are significantly harder to detect. Unlike the standard bugs, the burst variants will only transmit signals for short periods of time.

GSM bugs are similarly difficult to detect because they remain quiet for extended periods of time. On top of that, their signals can also match up with the ones emitted by mobile phones. You will need high quality RF detectors to find GSM bugs.

The self-recording bugs are nearly impossible to detect unless you are lucky enough to find exactly where one has been implanted. The saving grace for you is that the person who uses the self-recording bug will have to physically retrieve and replace this bug. They are not easy to use.

Some individuals may decide to use Wi-Fi bugs. The Wi-Fi bugs are also hard to spot using an RF detector, but you can sniff these out if you regularly check the people who are using your Wi-Fi.

Lastly, hidden camera bugs may also be placed inside your home, office, or car. To find these, you will need both a good RF detector as well as a lens detector.



The Factors to Consider When Shopping for an RF Detector

Now that we know more about the RF detector and which bugs it can detect, let’s discuss the factors that can differentiate them from one another.


Frequency Range

Different bugs produce different frequencies.

RFID tags can be used as tracking devices and they produce three to 30 megahertz (MHz) of frequency.

A step up from the RFID devices are the mobile communication devices. They are known to produce 30 to 300 MHz. Bluetooth devices, GPS devices, microwave appliances, mobile phones, Wi-Fi routers, and 2-way radios emit 300 MHz to three gigahertz (GHz) of frequency.

On the high end of the spectrum are GPS devices, more sophisticated Wi-Fi routers, and cordless phones. Cable and satellite TV broadcasting also produce high radio frequency. To be more specific, the aforementioned devices produce three to 30 GHz of frequency.

It would be best if you can find an RF detector that can sense frequencies that go to as high as 30 GHz, but that’s only necessary if you suspect that there are professionals attempting to track you.

In the absence of RF detectors that can go that high, you can settle for the devices that can sense frequencies from one MHz up to six GHz. Those detectors will be able to provide reliable performance and you should be able to get countless hours of great work from them.


Camera Detection Range

Because the RF detectors being offered today are more sophisticated devices, you can also rely on them to find any hidden cameras that may be nearby. To make sure that you get a detector that can capably locate hidden cameras, you need one with decent range.

For finding hidden cameras, you will want an RF detector that can spot them even if they are 32 feet away.



As you can imagine, these RF detectors will pick up all kinds of signals. If you take the time to check out every signal you detect, you will have to spend countless hours just tracking them down. Needless to say, that is an inefficient way to safeguard your privacy.

To get around that issue, you will need to find an RF detector equipped with quality filters.

If the RF detector you’re using is poorly made or just features bad components, it will likely pick up on all kinds of ambient signals. You may end up going on a wild goose chase to track down an ambient signal when there’s another more malicious one that slipped under your nose.

By ensuring that your RF detector has good filters included, you can save yourself plenty of potentially wasted hours.


Detection Modes

In certain situations, you don’t always want the people around you knowing that you are looking for electronic bugs. If you’re around your family, the last thing you want them to discover is that you suspect someone may be spying on all of you.

Thankfully, some RF detectors feature different modes that will enable you to discreetly search a specific area for electronic bugs.

Some detection mode will make use of lasers, vibrations, and beeps. Obviously, you can also refer to the LED display to check if something suspicious has found.

Also, some RF detectors feature something known as a protection mode. In protection mode, you can put on some headphones, listen to signals, and detect if certain transmissions are safe or unsafe. The signals you mark as safe will be remembered and they will not be brought to your attention moving forward.
