ARUD & MI-5 Optimum Monitoring Devices
Turning Innovation Into Protection
Sound Sentinel was founded to engineer practical, technology-driven solutions for real-world safety challenges. With ARUD, we’ve created more than a device, we’ve created a safeguard. Installed inside a firearm case, cabinet, or safe, ARUD continuously monitors for unauthorized access, movement, or tampering. The instant a firearm is handled without permission, it triggers live alerts, location tracking, and HD video capture providing immediate awareness and actionable information to prevent loss, theft, or tragedy.
Our Purpose Is Clear
We are diligently advancing ARUD:
Because lives depend on it. Every hour of delay risks another preventable incident.
Communities deserve better tools. Laws alone can’t stop unauthorized access, but technology can.
Responsible owners deserve peace of mind. ARUD provides security without compromise.
Innovation can save lives. We are proving that Canadian engineering can lead the world in firearm safety innovation.
Engineering With Integrity
Our team is meticulously completing ARUD’s design, testing, and production readiness to ensure it meets the highest standards of reliability, privacy, and performance. Every feature — from encrypted communications to advanced motion sensors is built with one mission in mind: protect what matters most.
A Shared Vision for Safer Communities
Sound Sentinel works closely with the National Firearm Safety Initiative (NFSI) and leading public safety advocates to ensure ARUD reaches every licensed firearm owner in Canada. Together, we aim to make proactive firearm security a national standard, accessible, affordable, and trusted.
We are not building another product. We are building peace of mind, protection for families, and a future where tragedies can be prevented not mourned. That’s why Sound Sentinel remains steadfast in its mission, we won’t stop until ARUD is protecting every home that needs it.
