    OPERATIONAL SCENARIOS

    When to use
    what.

    Six common situations our analysts encounter weekly. If your situation is on this list, the equipment we recommend is the equipment we would carry ourselves.

    SCENARIO 01

    Hotel room sweep

    You're traveling. Suite security is the hotel's word. Verify it yourself in twelve minutes before you take the first call.

    RECOMMENDEDSENTINEL
    SCENARIO 02

    Pre-meeting boardroom

    Quarterly deal off-site. Adversary has motive and means. Sweep the room before anyone arrives and again at the break.

    RECOMMENDEDSENTINEL
    SCENARIO 03

    Vehicle check

    You suspect a tail. Walk the perimeter — under, inside, wheel wells — and find what is broadcasting from your car.

    RECOMMENDEDSENTINEL + TRACER
    SCENARIO 04

    Private residence

    Cleaning staff turnover, contractor unknown. An RF sweep covers ninety-five percent of consumer-grade hidden devices.

    WHAT IT IS · WHO IT’S FOR · HOW TO CHOOSE · WHAT’S LEGAL

    01

    What this equipment is

    Counter-surveillance equipment is the set of tools used to detect, locate, and neutralise hidden surveillance devices — covert cameras, microphones, GPS trackers, and wireless transmitters. The category above covers four functions: radio-frequency (RF) detectors that pick up the signals transmitting devices emit, optical lens finders that reveal camera optics even when a camera is switched off, physical inspection tools for checking cavities and fixtures, and speech-protection systems that prevent conversations from being captured in the first place. This equipment is built for people who want to verify their own spaces — homeowners, tenants, frequent travellers, executives, lawyers, and anyone whose work or circumstances make privacy worth confirming rather than assuming. No technical background is required; every device here is selected to be operable by a careful non-specialist following a clear procedure.

    02

    The question it answers

    These tools answer a question that is otherwise unanswerable: is this space actually private? Typical situations are concrete and increasingly common — checking a hotel room or holiday rental before unpacking, verifying a home after a dispute, a renovation, or a period when others had access, confirming a vehicle is free of tracking devices, and protecting boardrooms or counsel meetings where the content of a conversation has real value. Consumer surveillance devices now cost less than a dinner out and are sold openly, which means the realistic response is not alarm but routine: a methodical sweep, done with the right equipment, that ends in a clear answer.

    03

    Choosing — and what’s legal

    Choosing between the options comes down to three questions. First, what are you checking — a hotel room on the move calls for compact lens and RF detection, a home or office justifies a fuller detection kit, and a meeting room where prevention matters more than detection points to speech protection. Second, who will operate it — single-button detectors suit first-time users, while wider-spectrum instruments reward practice. Third, how often — occasional travellers need less than someone running quarterly sweeps of business premises. On the legal side: owning and using detection equipment to inspect your own home, vehicle, or business is lawful across Switzerland and the EU. Speech-protection systems that acoustically mask conversations in your own space are likewise lawful to operate. What is restricted is different in kind — recording others without consent or operating radio jammers is prohibited in most European jurisdictions, which is why Sentiras sells neither. If you operate across borders, check the rules of the jurisdiction you are in; our support team can point you to the relevant guidance.

    Support, and where to start

    Every device in this category is tested before dispatch from our European facilities and ships with product guidance — if a reading confuses you or a sweep raises a question, you can ask for help from someone who knows the equipment. Just as important, no device here ships alone: each one is matched to a step-by-step procedure in the Sentiras Room Sweep Companion, so you are never holding a detector without knowing what to do with it. If you are unsure where to start, run the free Companion sweep first — it will tell you which equipment your situation actually calls for — or start from one of the curated kits in the catalog above, which pair the right devices for home, travel, or executive use.
