Service Details

Stage 1:  Radio Frequency Detection & Scanning

We use various advanced equipment and tools to perform a full width (0-24GHz) inspection of the electromagnetic spectrum and identify any suspicious signal transmissions, with the experience of our security specialists to ensure a full and comprehensive screening to uncover any transmitting unauthorized surveillance devices. ​


The high grade equipment include military grading radio frequency spectrum analyzers, radio frequency signal detectors, non-linear junction detector, alternating carrier current receiver etc.


Stage 2:  Physical Inspection

We also perform a physical inspection of high-risk electronic devices, electrical switches & sockets and ceiling to identify any non-transmitting unauthorized surveillance devices. ​


We may find it necessary to open up or switch on properties / devices to facilitate the inspection and affix security labels or marks on properties / devices which have been inspected in order to ensure that they would not be easily opened and fitted with unauthorized surveillance equipment.

Stage 3:  Recommendation


After the inspection, we will tailor-made a report that including findings, identified security risks or acoustic leakage and/or espionage by electronic surveillance devices and make recommendations to mitigate such risks. ​


We will suggest the implementation of risk mitigating measures such as access control, door lock and security surveillance, to secure clients against further non-sanctioned surveillance activities.
