Professional TSCM & Counter-Surveillance EquipmentDetect. Protect.
Control.

TSCM (Technical Surveillance Countermeasures) is the systematic technical inspection of rooms, vehicles and devices to detect and neutralize hidden microphones, covert cameras, RF transmitters and other eavesdropping systems. Arimas supplies the professional equipment used to perform these sweeps.

Over 100 professional security devices: RF spectrum analyzers, non-linear junction detectors (NLJD), bug detectors, IMSI catchers, jammers (RF, cellular, GPS, drone), audio-protection systems and secure communications — all for professional B2B use.

Products are intended for government agencies, law enforcement, military, intelligence agencies and enterprises with security needs. Sales are restricted to professional and institutional buyers.

Prices are not published: every product is quoted B2B on request. You submit a quote request from the site or email info@arimas.com, and the team replies within 24 business hours with a tailored proposal.

A bug detector locates hidden surveillance devices by analyzing radio-frequency (RF) emissions or, in the case of NLJDs, by detecting electronic components even when powered off. Arimas offers portable models and professional sweep systems.

An NLJD transmits a microwave signal and detects the harmonic return generated by semiconductor junctions inside electronic devices, even when they are switched off or shielded. It is the primary tool for finding concealed bugs, covert cameras and trackers that an RF-only detector would miss.

It takes a layered approach: (1) RF spectrum analysis for transmitting devices; (2) NLJD sweeps for powered-off or passive devices; (3) acoustic-stimulation detectors that locate microphone capsules; (4) physical inspection of surfaces, furniture and fittings. Professional TSCM equipment covers all four layers.

RF spectrum analysis maps every radio signal in an environment to identify anomalies that point to covert transmitters: hidden bugs, wireless cameras, GPS trackers or unauthorised communication devices. Professionals baseline the clean environment, then look for deviations.

An IMSI catcher is a device that intercepts the identity (IMSI) of mobile phones in an area to locate or identify them, used in investigative and security contexts. Arimas supplies portable and in-vehicle 2G/3G/4G models.
