Encrypted by Design
AES-128 encrypted digital voice. Even if a transmission is detected, the audio content cannot be recovered without the pairing key.
K9 Electronics designs and manufactures professional-grade covert listening devices and audio surveillance equipment in the United Kingdom — encrypted, frequency-hopping and engineered for low detectability. Supplied to law enforcement, government agencies and licensed professional users worldwide.
Commodity wireless microphones and consumer bugging devices broadcast in clear on a fixed channel — located and decoded in seconds by any counter-surveillance sweep. Our covert listening devices are engineered around operational security from the first component choice.
AES-128 encrypted digital voice. Even if a transmission is detected, the audio content cannot be recovered without the pairing key.
A true FHSS frequency-hopping listening device presents as transient noise on a spectrum analyser — no fixed carrier for an adversary to lock onto.
Voice-activated and store-and-forward burst options reduce the on-air footprint to seconds per day, defeating periodic RF sweeps.
Mains carrier-current listening devices move audio over building wiring — invisible to conventional RF detectors and air-spectrum surveys.
Designed, built and supported in Northampton. No third-country supply-chain exposure and no sanctions complications for export.
Bespoke concealments and distributor white-label programmes for established professional surveillance equipment resellers.
Most "spy bugs" sold online are GSM or fixed-frequency RF units — cheap, clear-voice and trivially detectable. K9 covert audio transmitters are a different class of equipment, built for users whose operations depend on not being found.
