Yorkie-Pro wireless intrusion detection system (WIDS) is a handheld receiver used for TSCM (Technical Surveillance Counter Measures) and wireless security audits of data-sensitive government, law enforcement and military facilities. Yorkie-Pro detects all nearby Cellular, Wi-Fi, Bluetooth and BLE (Bluetooth Low Energy) devices using a high-speed receiver engine in conjunction with a Wi-Fi/BT/BLE demodulator. Yorkie-Pro's passive receiver ensures all RF is detected, even RF interference and rogue devices invisible to the network. This means that all cellular signals (texts, voice and data) are detected - even RF pings to/from a cell phone in standby mode. This also means that Yorkie-Pro's cellular receiver can locate contraband phones, unauthorized bluetooth devices, rogue Wi-Fi APs and more using a specially designed direction finding antenna system. Yorkie-Pro is also the only device on the market that can detect and locate unknown tracking devices such as Apple AirTags, Samsung SmartTags and Tile Trackers as well as active GPS trackers. Yorkie-Pro contains a dual-band demodulating receiver for connection to any known bluetooth, BLE or Wi-Fi access point. Yorkie-Pro not only tracks and locates their whereabouts, but also provides logging capabilities and data snapshots for further analysis. Yorkie-Pro generates whitelists of known devices allowing security professionals to effectively focus on the true wireless threats. Yorkie-Pro's light weight, sleek profile and color touchscreen make it ideal for wireless security audits requiring a NO WIRELESS policy in any facility. Small enough to fit into most pockets for vibrating alerts, Yorkie-Pro can also handle desktop duty as an all day wireless activity monitor. Go handheld with Yorkie-Pro to sniff out all active cell phones use up to 150 feet away indoors and then swap the omni antenna for a direction finding antenna allowing outdoors ranges up to 1 mile away. Yorkie-Pro is designed and manufactured in the USA by a 50 year old, privately owned family business.
