Purpose-built RF instrumentation for TSCM and physical-security teams: portable, mission-tested and trusted by governmental and intelligence operators worldwide.
Berkeley Varitronics Systems (BVS) designs specialised RF instruments for detection, wireless security analysis and TSCM (Technical Surveillance Counter-Measures) operations. The Yorkie Pro, Wolfhound and Hound series are deployed by intelligence agencies, governmental clients and security professionals in more than 30 countries.
Wolfhound is the reference instrument for locating illicit cellular emitters inside sensitive perimeters: prisons, courts, exam rooms, government buildings. Frequency coverage spans GSM, UMTS, LTE and 5G bands with directional antenna for sub-metre localisation.
Yorkie Pro covers 10 MHz – 8 GHz with a single sweep, ideal for TSCM operations against bugs, hidden cameras and clandestine transmitters. Audio demodulation, waterfall display and selective DSP make it the workhorse of arimas TSCM field teams.
The Hound family targets handheld scanning and non-linear junction detection (NLJD) for security checkpoints and mail-room inspection. BVS hardware integrates with arimas operating procedures for ministerial sites and tribunal complexes.
Adopted by NATO governments, prison administration, intelligence services, mission-critical infrastructure operators and corporate security teams.
