Make sure your private life stays private.
Our home is our sanctuary. But easy access to tiny surveillance devices has made violations of our privacy increasingly common. Whether it's a bitter divorce, unscrupulous landlords, or unauthorized surveillance – no one should feel watched in their own home.
At Private Detectives Portugal , we conduct thorough home searches to ensure that there are no hidden “eyes” or “ears” in places where they don’t belong.
Where are the threats hiding?
Modern micro cameras can be disguised as ordinary objects:
Mobile phone chargers and extension cables.
Smoke detectors and alarm sensors.
Wall clocks, Bluetooth speakers, or decorative paintings.
Stuffed animals or personal hygiene items.
How do we protect your privacy?
We use a three-phase protocol that combines forensic technologies to eliminate errors:
1. Laser optical scanning (hidden lenses)
Many home security cameras only record to an internal memory card and do not transmit a radio signal. For these cameras, we use optical reflection technology . With our professional equipment, we can detect the reflection of the glass lens, even if the camera is only the size of a pinhead and switched off.
2. Detection of silent transmissions (RF)
Microphones transmitting via Wi-Fi or SIM cards (GSM) are isolated by our spectrum analyzer . We detect all unauthorized radio signals leaving your home, thus blocking audio leaks in real time.
3. Thermal testing of walls and objects
Cameras and recording devices hidden in walls or furniture generate heat. Our thermal imaging camera allows us to detect suspicious heat signatures behind surfaces, thus locating devices that would remain hidden during a visual inspection.
Maximum discretion
We understand that this is a sensitive issue.
Inconspicuous vehicles: We arrived at our destination discreetly so as not to arouse suspicion among the neighbors.
Confidential report: At the end of the search, we will send you a report with our findings and, if any devices are found, assist you in securing evidence for legal purposes.
Security notice: If you suspect your house is under video surveillance, please do not discuss hiring this service inside your home. Contact us from a safe outdoor location.
