A new chapter in remote confined space safety
For years, TeQ Shield™ GUARDIAN has helped industrial teams monitor confined spaces remotely and keep entrants safe during turnarounds around the world. Today, United Safety is building on that legacy: TeQ Shield™ GUARDIAN-PRIME officially replaces GUARDIAN as our remote confined space monitoring solution.
PRIME is not a minor refresh. It was built from the ground up using everything we learned from GUARDIAN deployments in demanding industrial environments, and it is engineered specifically for long-term, high-demand projects.
Built on years of field experience

Every upgrade in GUARDIAN-PRIME answers a challenge our teams have faced on site. Projects are running longer, vessels are more complex and conditions are harsher. GUARDIAN-PRIME adapts to your project scope and safety requirements, however complex the environment.
A single Access Control Module (ACM) can now power up to four cameras, giving your safety team multiple views inside the space from one setup. Connect a gas detector to the ACM and live gas readings appear alongside video feeds on a single dashboard, so your team can make faster, better-informed safety decisions.
What’s new in GUARDIAN-PRIME
- Industrial strength. Upgraded industrial components withstand extreme temperatures from -40°C to 50°C.
- Self-healing wireless mesh. A military-grade mesh network reconnects automatically if a node is blocked, keeping communication stable and secure while future-proofing the system for IoT integration.
- Shielded cabling. Upgraded, industry-shielded cable protects against electrical interference, wherever you operate.
- Uninterrupted power. Hot-swappable battery backups and a new battery expansion pack keep monitoring running, even during sudden site power losses.
- Clearer alarms and communication. New LED lights, improved alarm modules and upgraded two-way communication make sure critical safety signals are never missed.
- Tailored configuration. Choose from a range of camera styles and additional environmental sensors to match your exact vessel geometry.
- Secure by design. Industry-tested software and secure wireless networks keep your data protected.
