AES-128 Encryption
Digital voice encrypted before transmission. Detected audio cannot be recovered without the pairing key.
The K9-SAT-001 is the core encrypted listening device of the range — a compact, battery-powered covert audio transmitter delivering AES-128 encrypted digital voice over a frequency-hopping RF link.
The K9-SAT-001 is a professional RF listening device built around the S2-LP digital radio platform. It captures audio and relays it as an AES-128 encrypted, frequency-hopping transmission — a secure covert audio link that yields nothing usable to a counter-surveillance receiver even if the signal is detected.
As a digital encrypted audio transmitter rather than a clear-voice bug, it is the foundation of the K9 covert audio range. Body-worn or room-deployed, battery-powered for flexible placement, and paired with the K9-SAR-001 receiver for live monitoring.
Digital voice encrypted before transmission. Detected audio cannot be recovered without the pairing key.
Frequency-hopping spread spectrum presents as transient noise — no fixed carrier to lock onto.
Efficient 3200 bps voice compression maximises range and endurance over a narrow encrypted link.
Self-contained battery operation for rapid, flexible deployment without a mains connection.
Operates across the 868, 433 and 458 MHz bands, subject to local licensing.
Links only to an authorised K9-SAR-001 receiver holding the matching key.
Detailed figures — power output, sensitivity, range and endurance — are released to qualified buyers on enquiry, subject to end-user qualification and UK export controls.
