Electronic Sweep for Homes and Rooms

Do you suspect someone is listening to or recording what's happening in your home? Electronic scanning to detect hidden microphones, cameras, and recorders in homes, houses, and rooms.

Your home is the one place where you shouldn't have to watch what you say. When someone you know hears conversations that only took place there, or you simply notice something is off—a new electrical outlet, a charger that isn't yours, an object that's been moved—the suspicion of a hidden microphone or camera is hard to shake. These devices are inexpensive, bought online, and installed in minutes by anyone with access to the property. TSCM's comprehensive electronic sweep examines the home or room for all of them, both those transmitting and those silently recording.

This service includes the radioelectric, thermal, optical and physical inspection of the home, the explanation of the results and a legal opinion that assesses what was found and recommends how to act legally.

Who provides the service

The inspection and report are carried out by a law firm specializing in electronic countermeasures . The engagement is formalized directly with the firm, which provides a quote and invoices for the service, ensuring that all information regarding your case is protected by attorney-client privilege from the initial contact. ESPIAMOS® connects you with the firm; it does not receive any commission for this service.

To request the sweep, contact the office through their website or ask us for their contact details by phone or WhatsApp.

Why a professional sweep and not a detector bought online?

Modern listening devices don't transmit continuously: they broadcast in bursts when they detect voice, use your home's Wi-Fi network, or record to a memory device for later retrieval. A basic detector only picks up what's currently transmitting, and a self-check carries an added risk: if you find something and touch it, you'll destroy the evidence.

• Knowledge of the adversary : the firm knows the devices that are sold to monitor a home, where they are hidden, how they transmit and how they avoid being detected.
• Professional instrumentation : spectrum analyzers, frequency detectors, nonlinear junction detector for locating switched-off electronics, thermal imaging camera, optical lens detector and cavity endoscope.
• Documented methodology : the inspection records what has been examined and to what extent, allowing the result to be used later in court.
• Legal criterion : the person carrying out the inspection is a lawyer, and knows what to do with what he finds.

What does electronic home sweeping include?

The scope of the search is tailored to your situation in the initial interview: a single bedroom is not the same as a three-story house, nor is the suspicion about someone who has had access to the house the same as the suspicion about the person who sold or rented you the apartment. In all cases, the electronic sweep includes:

• Preliminary interview and risk analysis: what has happened, who has had access to the home, which rooms are important and since when the suspicion exists.
• Radioelectric inspection of the premises to detect GSM, 3G, 4G, 5G, Wi-Fi, Bluetooth, DECT and other technologies transmitters, with prolonged monitoring to capture intermittent emissions.
• Non-linear junction detection to locate microphones, recorders and cameras that are switched off or not transmitting.
• Optical lens detection to locate hidden cameras in smoke detectors, clocks, chargers, light fixtures or decorative objects.
• Thermal inspection to locate heat sources associated with hidden electronics.
• Physical and endoscopic inspection of furniture, sockets and power strips, light fixtures, headboards, false ceilings and cavities.
• When risk analysis advises it, check the landline phone, the socket, the router and the devices connected to the home network.
• Photographic and documentary record of the inspection and findings.
• Explanation of the results at the end and recommendations for protecting the home.
• Legal opinion signed by a lawyer, with the technical inspection report as an annex.

What does the legal opinion contribute?

If a device appears, The technical discovery is just the beginning. Who installed it, whether it was legal to do so, what legal avenues exist (civil and/or criminal), and how to preserve the evidence so it isn't challenged later are all legal questions. In the domestic sphere, moreover, the person who installed it is usually someone close—a partner, an ex-partner, a relative, a roommate, a landlord—and this influences both the legal classification and the course of action.

The legal report answers these questions based on the inspection carried out and is written by the same lawyer who conducted it. It is the document required to file a complaint, initiate family law proceedings, or make a claim against the landlord or seller.

When do you need this electronic sweeping service?

• Conversations that reach third parties : someone in your circle knows what has been discussed at home.
• Separation or divorce : you suspect that your partner or ex-partner, with access to the home, has installed something.
• Shared apartment, rent or buy : you want to know the conditions under which you receive a space that others have occupied before, or you suspect the landlord or a roommate.
• Hotel room or tourist apartment : have you found something strange or do you want to check it before a sensitive stay.
• Previous finding : You have already found or removed a device and want to check that there are no others.

What happens if a device appears during the TSCM inspection?

It's the difference between hiring a technician and hiring a practicing lawyer. If a microphone, camera, or recorder is located, the lawyer advises you on the spot, in your own home, about what has been found and the options available to you, and the strategy is decided right there, with you.

If you decide to file a report, your lawyer can directly notify the police on your behalf so they can take charge of the device from that moment. This ensures the chain of custody begins with your lawyer present from the very start, reducing the risk of the evidence being challenged later. It also prevents you from having to face an unfamiliar and often painful situation alone: it's not you who has to explain to the police what has been found and why, but your lawyer.

What you shouldn't do, with or without a lawyer, is remove the device, tamper with it, discuss the discovery within the room, or confront the person you suspect. This is a natural reaction, but it's what destroys the evidence and alerts whoever installed it.

Frequently Asked Questions about TSCM Electronic Sweeping in Homes and Rooms

Where is the sweep performed?

In Madrid and the provincial capitals of Galicia, there is no travel cost. It is also possible in other provinces; travel costs are quoted separately.

How long does it last?

Between two and three hours for a room or small apartment; a multi-room dwelling may require between three and six hours. This includes a prolonged spectrum monitoring phase.

How is the budget calculated and who handles the invoicing?

The firm provides a quote after the initial consultation, based on the number of stays and the agreed-upon scope. The firm formalizes the engagement and invoices; the quote, engagement letter, and privacy policy belong to them.

Do I have to be present? Will anyone find out?

It's best if you're present, because the lawyer will explain the results as they happen, and if anything new comes up, you'll decide together how to proceed. The team will arrive without a vehicle or any identifying clothing, and the sweep can be done at a time when the person you suspect is not at home.

Are furniture or electrical outlets being disassembled?

Only when necessary to access a suspicious area, and always with your prior express authorization. The lawyer informs you before any handling and documents it. The inspection leaves no marks or damage.

Does it detect devices that are turned off or not transmitting?

Yes. For this purpose, the nonlinear junction detector is used, which locates electronic components even when they are switched off or without a battery, along with optical lens detection and physical and endoscopic inspection.

Does he also check my mobile phone?

It is not part of the home sweep, but it is common for those who install a microphone at home to have also installed spyware on their mobile phone. The firm offers a specific service for detecting spyware on mobile phones, which can be combined with a sweep in the same order.

Will I know the result immediately?

Yes. At the end, the lawyer will explain what they observed and, if anything was found, how to proceed. You will receive the legal opinion in writing within the following days, in PDF format and signed by the lawyer.

Is it illegal to record what is said in my house?

Installing a microphone or camera to record conversations or images of another person without their consent in their home constitutes a crime against privacy. However, the legal classification depends on who installed it, where, for what purpose, and what was recorded; therefore, the assessment of the discovery is a legal matter and falls under the jurisdiction of the court.

Can I buy the equipment and do it myself?

ESPIAMOS® distributes electronic scanning equipment for users and professionals. A personal detector can serve as an initial check, but it has the limitations described above. In cases of specific suspicion, a professional scanning with a legal opinion is the appropriate option.

Does this service also include the car?

No. For vehicles, we offer a comprehensive electronic vehicle cleaning service , which our office can combine with home cleaning in a single order. If you're looking for office or business premises cleaning, please see our office and business service .
