What is a bug sweep (TSCM)?

A bug sweep, or TSCM (Technical Surveillance Countermeasures) inspection, is a professional search for hidden microphones, RF transmitters, concealed cameras and GPS trackers. It combines RF analysis, optical lens detection and physical inspection, and is carried out only with the consent of the property owner or lawful occupant.

Hidden camera detection: where professionals look first

Tap a numbered hotspot to see why it’s a common hiding place and what a trained investigator checks. Please don’t take things apart yourself — you could damage evidence.

Smoke detector

Why it’s a common hiding place
High on the ceiling with a clear view of the whole room, rarely touched — and most people assume the landlord, MCST or building installed it.
What a professional checks
Whether it matches the unit originally fitted, signs of a lens aperture, RF emissions around the housing, and a careful physical inspection.

Tip: photograph your ceiling fixtures today. Knowing what “normal” looks like makes change easier to spot.

Warning signs

Signs you may be bugged — and the innocent explanations

We’d rather you feel calmer than more worried. Here’s what people notice, alongside what it usually turns out to be.

  1. Someone knows what you only said in privateCould also beA shared calendar, a synced device or a talkative friend.
  2. An unfamiliar USB charger, adapter or power strip appearsCould also beA family member or colleague may simply have bought it.
  3. A smoke detector, clock or vent has moved slightlyCould also beCleaners and aircon servicing move things all the time.
  4. Ceiling tiles out of line, or fine dust beneath themCould also beBuilding maintenance, pests or old tiles settling.
  5. A new device near your car’s OBD port or under the dashCould also beA workshop or fleet manager may have fitted it.
  6. Odd clicks, static or volume drops on callsCould also beUsually the network or an ageing handset — rarely a bug on its own.
  7. A new gift or gadget that always faces where you sitCould also beMost gifts are just gifts.

One sign on its own rarely means much. Several together — plus someone with a motive and access, such as during a divorce, a business split or a tense negotiation — is when a sweep makes sense.

Ladybird on a green leaf — the only kind of bug you want to find at home

Wrong kind of bug. The ones we look for are far less photogenic — and they don’t sit out in plain sight.

Worth sharing

Think you’re bugged? Four quiet rules before you call.

The most useful counter-surveillance advice costs nothing.

  1. Don’t talk about it in the room.If the space is compromised, so is the conversation about sweeping it.
  2. Use a different phone, in a different place.Contact us from a device that hasn’t been out of your control, away from the suspected space.
  3. Don’t hunt for it or pull things apart.Disturbing a device can destroy evidence and tip off whoever placed it.
  4. Keep your routine normal.Sudden changes can signal that you’re on to it. Let us do the looking.

What a sweep involves

Counter-surveillance in Singapore, step by step

Discreet from the first call. We never need to discuss details inside the space we’re checking.

  1. Off-site briefing

    A confidential conversation away from the suspected space. We confirm you own or lawfully occupy it, and that you consent to the sweep.

  2. Plan & quotation

    Which rooms, vehicles or venues, when (including after hours), and a written quotation before any work starts.

  3. The sweep

    RF analysis, optical lens detection and physical inspection of the agreed areas by licensed investigators.

  4. Findings & report

    A clear account of what was checked and found, with photos and practical recommendations.

After the sweep

What you get — and what happens if we find something

  • A written report listing the areas, fixtures and vehicles checked.
  • Findings with photos — including a clear statement when nothing was found.
  • Practical recommendations, such as tightening access, changing passwords on your own smart devices and when a repeat sweep makes sense.
  • A debrief by phone or in person, away from the swept space if you prefer.

If a device is found

  1. We stop and document it in place — photos, location and condition.
  2. We don’t tamper with evidence. The device is left as found.
  3. We advise on reporting it to the police, and on practical next steps for your safety and privacy.
  4. We can support what comes next — for example, evidence for your lawyer in a dispute or a harassment matter.

Singapore context

Bug sweeping in Singapore: consent, condos & the law

A sweep is only as trustworthy as the way it’s done. Here’s how it works in practice here.

  • HDB flats & condosOwners and lawful occupants can consent for their unit. Common areas belong to the MCST or Town Council — we’ll advise if a concern extends there.
  • Renting or staying short-termAs a tenant or guest you’re the lawful occupant of the space you rent, and we can sweep that space with your consent.
  • Offices & boardroomsThe company or an authorised officer consents. We coordinate with building management for after-hours access where needed.
  • VehiclesCars you own or lawfully use — including company vehicles, with the company’s consent.
  • The lawCovert access to phones or computers can breach the Computer Misuse Act; stalking-type monitoring may fall under the Protection from Harassment Act (POHA); the PDPA governs personal data.
  • Licensed & accountableWe operate under the Private Security Industry Act with PI licence L/PS/000759/2025. We’re not a law firm — speak to your lawyer about your situation.

What we do

  • Sweep homes, offices and vehicles you own or lawfully occupy, with consent
  • Look for microphones, RF transmitters, cameras and GPS trackers
  • Document any device found, in place, with photos
  • Advise on reporting to the police
  • Recommend practical steps to protect your privacy

What we will never do

  • Sweep property without the owner’s or lawful occupant’s consent
  • Remove, keep or tamper with a device we find
  • Install hidden cameras, bugs or trackers on anyone
  • Hack or “check” someone else’s phone or accounts
  • Promise a space will stay bug-free forever

FAQ

Bug sweeping in Singapore: common questions

More FAQs
How much does a bug sweep cost in Singapore?

It depends on the size of the space, the number of rooms and vehicles, timing (for example after office hours) and the reporting you need. A two-bedroom condo is a different job from an office floor with several meeting rooms. After a confidential discussion we give you a written quotation before any work begins.

How do I know if my home or office is bugged?

Common signs include someone knowing things you only said in private, unfamiliar chargers or gifts appearing, fixtures that have shifted and unexplained devices in your car. No single sign is proof — many have innocent explanations. A professional sweep uses RF analysis, optical lens detection and physical inspection to give you a clear answer.

Is bug sweeping legal in Singapore?

Yes, when it is carried out with the consent of the property owner or lawful occupant. Ranger is a private investigation agency licensed by the Singapore Police Force (licence L/PS/000759/2025). We only sweep homes, offices and vehicles that you own, lawfully occupy or are authorised to have checked.

Can you check my car for a GPS tracker?

Yes — for cars you own or lawfully use, including company vehicles with the company’s consent. We check the OBD port and under-dash area, the boot and exterior, and look for RF and cellular activity. If we find a device, we document it and advise you on next steps.

What happens if you find a hidden camera or listening device?

We stop, photograph and document it in place. We don’t tamper with evidence. We then advise you on reporting it to the police and on practical next steps — for example, speaking to your lawyer if it relates to a dispute or harassment.

Can you sweep a room I rent or a hotel room?

Yes. As a tenant or guest you are the lawful occupant of the space you rent, and we can sweep that space with your consent. For hotel suites and function rooms booked for meetings, we coordinate with the venue where needed.

Do hidden camera detector apps work?

Phone apps can sometimes spot an obvious lens reflection or a device on your Wi-Fi, but they miss a great deal and can give false reassurance. A professional TSCM sweep combines RF analysis, optical lens detection and physical inspection by trained investigators.

Can you check my phone for spyware?

Phone checks fall under digital forensics, which we carry out only on devices you lawfully own or are authorised to access. See our digital forensics service, and if you suspect your phone, contact us from a different device.
