A generation ago, covert video required resources that limited it to professionals. Today a camera smaller than a shirt button, with a week of battery and cloud connectivity, costs less than dinner and ships overnight. The capability democratised; the threat model has not caught up.
The commodity surveillance economy
The devices we recover are overwhelmingly commercial products: cameras built into chargers, power banks, smoke detectors, clocks, air fresheners, picture frames and screw heads, sold openly online in unlimited quantity. The quality is remarkable: high-definition, motion-activated, remotely viewable. Placement requires no skill whatsoever. This matters because it changes who the adversary can be. Professional espionage still exists, but the growth is in amateur deployment: disgruntled staff, suspicious spouses, extortionists, landlords, competitors' local fixers. Capability is no longer the barrier. Intent and access are all that remain.
Where the risk actually falls
For organisations, optical devices target what audio cannot: whiteboards, screens, keyboards and documents. A camera above a trading desk or a deal room whiteboard is worth more than a microphone in the same space. For principals and families, the exposure is more personal: bedrooms, bathrooms, hotel suites and serviced apartments, where the product is not information but leverage: extortion material, matrimonial evidence, or content whose mere existence is the harm. Regional casework and periodic prosecutions across Asia's cities confirm both patterns are routine, not exotic.
Detection is a discipline, not an app
Consumer folklore finds only the laziest devices: the phone-camera lens check, the cheap detector gadget, the Wi-Fi scan. Serious optical detection layers several methods: physical search by inspectors who know concealment products and construction voids; lens detection optics that find a camera whether or not it is powered; RF and network analysis for transmitting devices; and thermal and non-linear junction techniques for hardware that stores rather than sends. It is methodical, unglamorous work, which is why it succeeds. Every Risk3 inspection includes the full optical layer as standard, in boardrooms and bedrooms alike.
One operational note bears repeating: a discovered camera is evidence. Pulling it from the wall destroys placement forensics, fingerprints, and the data trail that connects device to operator. Leave it, say nothing near it, and take advice. Handled correctly, the device that watched you becomes the exhibit that convicts whoever placed it. See our guidance on discovering a device.
