    FREQUENTLY ASKED

    Questions answered.

    What is the Sentiras SHADOW device?

    +

    The Sentiras SHADOW is a GSM audio transmitter integrated into a functional power strip format. It is designed for lawful professional monitoring contexts where discreet form factor and continuous power are required. It should only be deployed with proper legal authority and consent.

    How does SHADOW audio capture and alerting work?

    +

    The Sentiras SHADOW uses a Knowles microphone and supports live call-in listening over GSM. VOX mode can trigger callback behavior when sound crosses configured thresholds. Sensitivity and control parameters are managed remotely via SMS commands.

    What are SHADOW's operational limits?

    +

    The Sentiras SHADOW depends on GSM availability and SIM service quality for remote access. Audio quality can vary with room acoustics, distance, and noise floor. It is not suitable where cellular service is unavailable or prohibited.

    How does SHADOW compare with fixed CCTV or NVR systems?

    +

    The Sentiras SHADOW focuses on audio intelligence through a low-visibility form factor, while CCTV/NVR systems are primarily overt video platforms. Fixed camera systems may offer broader evidentiary context but are easier to identify. Selection depends on lawful mission requirements and disclosure obligations.

    Who is the right buyer fit for the SHADOW?

    +

    The Sentiras SHADOW is generally suited to licensed investigators, authorized security teams, and institutional users with compliance oversight. It is not positioned for casual or personal misuse scenarios. Procurement should include legal review before operational deployment.

    What legal and compliance controls are required for remote audio tools?

    +

    The Sentiras SHADOW must be used in jurisdictions and scenarios where audio monitoring is lawful and authorized. Users should confirm consent, warrant, or employer-policy basis as applicable before activation. Sentiras does not support unlawful interception or privacy violations.
