The concealment of a surveillance device depends on two requirements: access to the location and the ability to place an object or modify an existing one without the discovery being obvious. In a residential property, both of these conditions can be met in a surprisingly large number of locations, which is why a professional sweep covers every room systematically rather than checking only the most obvious places.
This article explains the most common hiding places for covert listening devices and hidden cameras, based on the devices we find in the course of our work.
Electrical Fixtures and Fittings
Electrical fixtures are ideal hiding places for surveillance devices because they justify a physical presence on walls and ceilings, they have access to mains power, and their internal spaces are sufficient to conceal a small device. The most commonly exploited fixtures are:
- Plug sockets, particularly double sockets where the internal space behind the faceplate is larger than it appears. A device installed behind a socket faceplate has mains power, is invisible without disassembly, and is in a location that nobody questions.
- Light switches, for similar reasons. Dimmer switches and smart switches have more complex internals with additional space.
- Smoke detectors, which are already ceiling-mounted, face the room, and justify a small aperture. Consumer-grade hidden cameras specifically designed to mimic smoke detectors are widely available.
- Extension leads and plug adapters, which are everyday items that justify their position near seating or sleeping areas and can be purchased pre-modified to conceal a camera or microphone.
Everyday Objects
Surveillance devices are commonly concealed within or disguised as everyday objects, because such objects justify their presence in the space and are not subjected to close examination. The most frequently encountered are:
- Clock radios and digital alarm clocks, particularly on bedside tables. Their position facing the bed and their legitimate presence in the room make them an ideal vehicle for hidden cameras.
- USB chargers and phone charging blocks, positioned at plug sockets throughout the house.
- Books, ornaments, and decorative items, which can be positioned to face specific areas of the room.
- Picture frames and mirrors, particularly on walls facing common areas.
- Air fresheners and diffusers, which are small, battery-powered, and expected to be positioned on surfaces throughout the property.
- Stuffed toys and cushions, particularly in family homes and children’s bedrooms.
Structural Locations
Devices that are less accessible and intended to remain in place for extended periods are sometimes installed in structural locations: within wall cavities, above ceiling tiles, below floorboards, or within the housing of existing legitimate electrical equipment. These locations require more technical knowledge to access and are less common in residential cases, but they are encountered and require the NLJD component of the sweep to detect.
Vehicles
In vehicles, the most common hiding places for GPS trackers are under wheel arches, behind bumpers, on the underside of the frame, and in the OBD port under the dashboard. Audio recording devices in vehicles are less common but may be concealed within the interior trim, behind seats, or within the vehicle’s entertainment system.
A Note on Bathrooms
Hidden cameras in bathrooms are, unfortunately, one of the most serious categories of device we encounter. In rental property cases in particular, cameras in bathrooms and bedrooms are the primary concern. All bathroom fixtures, including shower heads, air fresheners, and any non-standard item in the bathroom, are examined as part of a comprehensive sweep.
