Here’s what I learned and what helped me make an informed decision.
Understanding What a Hidden Audio Recording Device Is
Hidden audio recorders are small devices designed to capture sound discreetly without drawing attention. They can be disguised as everyday objects like pens, USB drives, clocks, or even buttons.
