Wolfhound-PRO Cell Phone Detector is a precision, handheld, wireless sniffer specifically tuned to the RF signature of common cell phones (both U.S. & international bands) including LTE, AWS, PCS, CDMA / WCDMA (UMTS), GSM, EGSM Cellular bands as well as GPS trackers and even DECT 6.0 cordless phones that cause interference with European cellular carriers.

Wolfhound™-PRO's award-winning*, high speed scanning receiver utilizes a multi-band DF (Direction Finding) antenna system allowing security personnel to locate nearby cell phones in either standby mode or during active voice, text or data RF transmissions making it the perfect tool for enforcing your NO WIRELESS security policy.
Wolfhound-PRO's simple trackball/pushbutton operation and ultra-bright OLED screen make it easy to use for both trained and untrained security personnel. In addition, Wolfhound-PRO identifies each cellphone by frequency allowing for detection and listing of multiple cellphones.

This can prove useful in situations in involving a variety of cellphone use such as large prisons and even disaster zones involving search and rescue operations. Wolfhound-PRO has up to 50 meter radius for cell phone detection (indoors) and up to 1 km outdoors (line-of-sight) making it the most sensitive cell phone detector on the market.




  • Receiver design boasts a dynamic range of -60 dB with user settable sensitivity
  • Detects cell phones up to 50 meter away (indoors) and up to 1 km away (line-of-sight outdoors)
  • Identifies each phone by frequency allowing for multiple, simultaneous cellphone detection
  • User selectable from -83 dBm to –53 dBm with a resolution of 2 dB for detection in a noisy environment (typical of prisons)
  • Selectivity rejection of at least 50 dB at 1 MHz from the uplink frequency bands provides high immunity from false triggering caused by base stations, personal communication devices and other sources of interference
  • Software (optional) logging capability allows the user to record and time-stamp every detected cell phone transmission via built-in USB port.
  • User selectable mobile frequency bands allow the same unit to be used around the world; both USA and European mobile uplink bands are supported
  • Detects DECT 6.0 cordless phone standard
  • Integrated laser-assisted directional antenna (green 532 nanometer laser, 15 meter mimimum span)
  • Internal Li-ION battery runtime of 4+ hours

Frequently Asked Questions:

Does the Wolfhound-PRO Cell Detector identify callers or their phone numbers?

No. Wolfhound-PRO Cell Detector is a precision RF cellular scanning device that identifies cellphone activity (both standby mode and active modes) and assists in locating them. It is a wireless tool used by security officers and personnel that require a  
NO WIRELESS security policy.

Can Wolfhound-PRO detect more than one cellphone at a time?

Yes. Wolfhound-PRO can identify the strongest cellphone and eliminate that from the search by either RSSI or frequency. This allows many cellphones to be detected at once.

How far away can I detect cellphones?
Typical range is about 50 meter but this varies depending upon the environment.

Does Wolfhound-PRO Cell Detector detect phones that are powered off?
No. A phone that is turned off cannot be detected with the Wolfhound Pro. Please look at our Spider Detector. He is able to detect cell phone powered off.

Can Wolfhound-PRO detect text messaging as well as voice calls?
Yes; as long as the RF transmissions are made over the prescribed frequency band(s) the Wolfhound-PRO receiver will detect them. However, since text transmissions tend to be short and intermittent (as opposed to voice or conversation which is more continuous), the user would have to pay un-divided attention to the Wolfhound-PRO LCD output to observe text messaging in real-time.

Can Wolfhound-PRO detect other RF activity?
Yes, Wolfhound-PRO will also detect GPS trackers and DECT 6.0 cordless phones.

Can Wolfhound-PRO only detect cellphones or can it locate them as well ? If so, how?
Wolfhound-PRO can both detect and locate cell phones. After detection, the cell phones may be located by determining the initial direction of maximum signal and then approaching the cell phone in slow steps, along the initial direction of maximum signal (or, a Line of Position) and continually updating one's direction for maximum detected signal.

Can Wolfhound-PRO stimulate a cell phone to transmit RF signals?
No, Wolfhound-PRO only detects RF signals; to stimulate a cell phone it would have to transmit RF signals, which would violate FCC regulations and guidelines.

Can Wolfhound-PRO units be networked together?
Currently, the Wolfhound is available as a stand-alone, handheld unit only.
