Deveillance founder Aida Baradari built a jammer to protect private conversations from recording devices
Mar 26, 2026 with Aida Baradari
Key Points
- Deveillance's ultrasonic jammer detects nearby recording devices and generates artificial audio to corrupt captured conversations, addressing the risk of ambient capture from AI wearables like Meta Ray-Bans.
- The device costs $1,000 at pre-order, ten times the price of a basic recorder, due to the processing overhead required to run detection and obfuscation simultaneously.
- Deveillance is developing an enterprise-grade version alongside consumer pre-orders and exploring form factors like smartwatches to reduce costs and expand the addressable market.
Summary
Aida Baradari is building Deveillance, an anti-surveillance hardware company. The core product is a smart ultrasonic jammer that detects nearby recording devices, directs distortion signals toward them, and uses an AI algorithm to generate artificial tones and voices that make captured audio hard to reconstruct in post-processing. That three-step pipeline — detect, block, obscure — is what drives the cost above a passive recorder, which needs little more than a microphone.
The problem Baradari is targeting is ambient recording from always-on AI wearables. She points to the wave of AI companion devices that launched in early 2024, where a forgotten device in a room can capture confidential conversations and feed them into training data the user never consented to. Meta Ray-Bans are the more recent version of the same risk: a bystander wearing them can record without any visible signal.
Pricing and customer mix
The device currently pre-orders at $1,000. Pre-orders so far are predominantly consumer-facing. Baradari acknowledges the economic asymmetry directly — a recording device costs roughly $100, the countermeasure costs ten times that — and attributes the gap to the processing overhead required to run detection and obfuscation simultaneously. She says cost reduction is a priority, and a separate enterprise-grade version targeting organizations with stricter requirements is also in development.
Legal landscape
RF jamming is illegal in the US because it can interfere with emergency services. Ultrasonic jamming operates in a different domain, though Baradari is careful not to claim blanket legality. On the recording side, one-party versus two-party consent law exists on paper — California is nominally two-party — but neither she nor the interviewers treat enforcement as a practical constraint today.
Form factor is still being explored. The watch format came up as a potential commercial hit. The device is available for pre-order at www.deveillance.com.
