Which Radio Frequency Detector Locates GSM and UHF?
Over the years, we've seen an increasing number of reports of hidden cameras and recording devices found in public locations, such as hotels, offices, and rental units.
Some of our top-selling items are our counter-surveillance equipment. These radio frequency detectors make it easy to sweep a room for hidden cameras and other recording bugs.
To help you better understand how hidden recording devices work, we'll go over the different types of frequencies used by these devices and how you can spot them.
What Frequency is GSM?
GSM frequency bands (cell phone signals) work along a spectrum that allows for wireless mobile signals.
The uplink for GSM frequency operates between 880 MHz to 915 MHz. The downlink frequency is between 925 MHz to 960 MHz.
Our Multi-Use RF detector can pick up signals in the range of 50 MHZ to 6.0 Ghz which means it can detect GSM signals.
If you are in an area with a lot of competing signals, our professional model can help you trace one specific signal.
What Frequency is UHF?
UHF is the abbreviation for ultra-high frequency—this portion of the electromagnetic spectrum functions at a frequency between 300 Mhz to 3,000 Mhz (3GHz). Therefore, "UHF" is a broad-ranging term that applies to a very wide frequency band, encompassing most standard frequencies used in daily life such as WiFi, Bluetooth and cellular signals, as well as among modern navigation technologies and broadcast television.
This spectrum can be detected by any of our RF Detectors.
What Frequency is Wi-Fi?
Wi-Fi frequency bands work along a spectrum for wireless connectivity.
Wi-Fi frequencies are split into channels, with the most common frequency being 2.4 GHz and 5 GHz (5G). Many Wi-Fi routers on the market today can support either of these frequencies.
Our Professional Digital RF Detector is an especially good choice for finding WiFi signals, with a secondary antenna that looks specifically for the 2.4GHz and 5GHz signal bands.
What frequency do most remote recording devices use?
Although hidden recording devices can technically use almost any frequency, some are more common than others.
Most remote recording devices operate at a frequency between 10 MHz to 8 GHz. However, they often have defense mechanisms built-in to prevent their detection without the right equipment. So, depending on what power source is being used for a bug, the frequency will vary.
With that in mind, it's important to find bug detectors that scan for a broad range of frequencies, slightly beyond the frequencies used by hidden recording devices.
We offer affordable models that sweep the most commonly used ranges, on up to professional models that can sweep nearly every manmade signal. Shop RF Detectors.
What frequencies do Radio Frequency Bug Sweepers use?
Radio frequency bug sweepers offer detection along the range of the UHF spectrum, with some reaching much higher, up to 10GHz.
This range allows them to detect a wide variety of frequencies even from a distance. In fact, most bug sweepers can detect radio frequency signals from up to 5 feet away or more, however it is always best to sweep from within a distance of 1 to 2 feet from whatever you are testing so you can determine exactly what is or is not producing suspicious signals.
These sweepers rely on sensitive antennas and easy to see alerts for when frequencies are detected. They will inform the user of a frequency detection either through visual cues or audible sounds; some sweepers may even vibrate to alert the user of a bug nearby.
Radio frequency bug sweepers also have signal strength indicators and unique sensitivity settings to help with detection. This allows the user to customize their device's sensitivity to help isolate the signal source of a potential hidden device.
The frequency range allows for many devices to be included on the detectable items list. From wiretapping devices to hidden cameras, radio frequency bug sweepers can quickly and effectively locate them.
Due to the range of frequencies they can detect, these devices are a good option for anyone that doesn't know what type of device they're searching for but suspects that one may be present.
How to find hidden cameras that don't transmit on a frequency?
Wireless surveillance is a great tool, but not every camera is transmitting a signal to be received elsewhere. Many devices in use today simply record onto micro memory cards, or SD cards, and only require the owner to pull the flash memory from the device in order to review the footage on their own time.
Not only can radio frequency bug sweepers detect frequencies from a hidden device, but certain models can even find some devices that are not transmitting or even not turned on at all with special camera lens finders that can locate camera lenses up to 30 feet away within the cameras' line of sight. The Anti Spy Hidden Camera Finder with LCD IR Detector can also find night vision LED's, which is a cutting edge advantage when it comes to locating hidden wireless devices.
Sweepers such as these have an LED light switch and tinted viewfinder for users to look through. If the user spots something flashing back through the lens, this may indicate the location of a hidden lens. If seen from any angle then it's more likely an LED bulb, however if the reflection cuts off as you move side-to-side you may be finding a camera lens due to the camera having a certain field of view. Get up close, and if possible, pick up the object in question and give it a closer examination.
Which is the best bug sweeper for me?
It's really going to depend on what is possible for someone else to use in order to spy on you. If you're looking in your home for something suspicious, you'll need to be checking all the knick-knacks, appliances and furniture in your area, so a great option is to get either a device that is both a bug sweeper and hidden camera lens finder, but a device that looks specifically for certain signal types would be best in an apartment complex with all the possible interfering signals in the area. Sometimes it's best to get a combination of devices for their different special features or frequency pickup ranges.
