Wolfhound™ Ultra is an award-winning handheld cell phone detector with a laser-assisted direction-finding antenna, locating nearby phones in standby or during active voice, text and data transmissions.
Wolfhound™-Ultra’s award-winning*, high speed scanning receiver utilises 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™-Ultra’s passive receiver technology does NOT intercept or “listen-in” on any phone calls, making it fully legal.
Wolfhound™-Ultra Cell Phone Detector is a precision, handheld, 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 U.S. DECT 6.0 cordless phones that cause interference with European cellular carriers.
Wolfhound-Ultra’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™-Ultra identifies each cell phone by frequency (not phone number or IMEI) allowing for detection and listing of multiple cell phones. This can prove useful in situations involving a variety of cell phone use such as large prisons and even disaster zones involving search and rescue operations. This also means that Wolfhound™-Ultra is legal and the preferred tool of choice for law enforcement looking to avoid time consuming court orders required by the use of some more complex and illegal phone interception devices. Wolfhound™-Ultra 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™-Ultra is designed and manufactured in the U.S.A.
*Standby mode (autonomous registration) varies from base station to base station with phones typically registering between once every few minutes to up to 20 minutes. This time varies greatly based upon carriers, distance from base stations and individual handset manufacturers’ standards.

No. Wolfhound™-Ultra Cell Phone Detector is a precision RF cellular scanning device that identifies cell phone 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.
Yes. Wolfhound™-Ultra can identify the strongest cell phone and eliminate that from the search by either RSSI or frequency. This allows many cell phones to be detected at once.
Typical range is about 150 feet but this varies depending upon the environment.
No. A phone that is turned off cannot be detected.
Yes; as long as the RF transmissions are made over the prescribed frequency band(s) the Wolfhound™-Ultra 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™-Ultra display to observe text messaging in real-time.
Yes, Wolfhound™-Ultra will also detect GPS trackers and U.S. DECT 6.0 cordless phones.
Wolfhound™-Ultra 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.
No, Wolfhound™-Ultra only detects RF signals; to stimulate a cell phone it would have to transmit RF signals, which would violate FCC regulations and guidelines.
No, Wolfhound™-Ultra only detects RF signals.
Currently, the Wolfhound™-Ultra is available as a stand-alone, handheld unit only.
Wolfhound™-Ultra is the most sophisticated and sensitive detector in its range. Please consult with our sales team to find the best product to fit your wireless security needs.
The internal Li-Ion polymer battery provides a minimum runtime of over 4 hours.
Yes. Frequency bands are field-selectable across U.S., international cell phone uplink and DECT 6.0 band sets. Ask our sales team about your country’s bands, including a custom set.
Direction-finding and omnidirectional antennas, a black ABS hard travel case and a lithium polymer battery charger. PC logging software is optional.
