Wolfhound-Lite Cell Phone Detector is a belt-mounted, wireless sniffer specifically tuned to the RF signature of common cell phones including PCS, CDMA / WCDMA, GSM and Cellular bands. Wolfhound-Lite's high speed scanning receiver utilizes a multi-band, internal omni-directional antenna system allowing security personnel to locate all nearby cell phones in standby mode* or actively using voice, text (SMS) or data transmissions. Wolfhound-Lite's compact and discreet design makes it the perfect stealth tool for enforcing your NO WIRELESS security policy in universities, government & military installations, hospitals, law enforcement agencies, financial institutions, prisons & correctional facilties. Like a pager, Wolfhound-Lite's simple yet effective design prevents wireless usage by alerting the operator via an OLED screen and/or vibrating alerts that detect and even aid in locating the wireless perpetrator.
