The Wolfhound Cell Detector from Berkeley Varitronics is a hand-held, wireless sniffer tuned to the RF signature of common cell phones that enables enforcement of no-wireless policies, according to the company.
Wolfhound's high-speed scanning receiver utilizes a multi-band DF (Direction Finding) antenna system that allows security personnel to locate nearby cell phones in either standby or active mode using voice, text (SMS) or data transmissions.
The device can access PCS, CDMA/WCDMA, and GSM cellular bands, according to the company.
