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 U.S. 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 TSCM 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 150 foot radius for cell phone detection (indoors) and up to 1 mile outdoors (line-of-sight) making it the most sensitive cell phone detector on the market. Wolfhound-PRO™is designed and manufactured in the U.S.A.

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 150 feet 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.


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 U.S. 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 track phone numbers or IMEI codes?

No, Wolfhound-PRO only detects RF signals.


Can Wolfhound-PRO units be networked together?

Currently, the Wolfhound is available as a stand-alone, handheld unit only.


How is the Wolfhound-PRO different from the Wolfhound and other BVS cell phone detectors?

The Wolfhound-PRO is Berkeley's most sophisticated and sensitive cell phone detector to date. Please consult with our sales team to find the best product to fit your wireless security needs by calling TOLL FREE 1-888-737-4287 or 732-548-3737.
