Mobile Phone Security Monitor


Wolfhound-Pro Mobile Phone Detector

Wolfhound™-PRO Mobile Phone Detector is a precision, hand-held, wireless sniffer specifically tuned to the RF signature of common mobile 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 carriers and Mobile Network Operators. Wolfhound™-PRO’s award-winning*, high speed scanning receiver utilises a multi-band DF (Direction Finding) antenna system allowing security personnel to locate nearby mobile 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/push button operation and ultra-bright OLED screen make it easy to use for both trained and untrained security personnel. In addition, WolfHound™-PRO has up to 150 foot radius for mobile phone detection (indoors) and up to 1 mile outdoors (line-of-sight) making it the most sensitive mobile 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 +44 (0) 2030 595777.
