PWAS – Proximity Warning & Alert Systems in Saudi Arabia
Prevent Collisions Before They Happen. Protect Lives, Assets, and Operations.
Shield Sensor delivers advanced PWAS (Proximity Warning & Alert Systems) designed for high-risk Saudi work environments where people, vehicles, and heavy machinery operate in close proximity.
Our AI-powered, radar-driven, and sensor-based PWAS solutions provide real-time visual and audible alerts, helping operators take action before accidents occur.
- Approved for ARAMCO & NEOM projects
- Built for harsh Saudi environments
Why Pwas Is Critical?
Why Proximity Risks Remain One of the Leading Causes of Accidents
Across construction, oil & gas, logistics, mining, and industrial sites, the most frequent fatal incidents occur due to:
- Limited operator visibility
- Blind spots around heavy vehicles
- Pedestrians working close to moving equipment
- Congested worksites with poor line-of-sight
- Delayed human reaction time
Traditional mirrors, cameras, and signage are not enough.
PWAS acts as an active safety layer — not a passive one.
What Is a Proximity Warning & Alert System (PWAS)?
A PWAS (Proximity Warning & Alert System) is an intelligent safety solution that detects people, vehicles, or obstacles around heavy equipment and commercial vehicles and immediately alerts the operator through audible and visual warnings.
Shield Sensor PWAS uses a combination of:
- Advanced radar technology
- AI vision cameras
- Microwave & ultrasonic sensors
- Wearable personnel tags
to provide 360-degree proximity detection, even in environments where visibility is limited.
How Our PWAS Prevents Accidents in Real Time?
1. Continuous Detection
Radar, sensors, or AI cameras constantly monitor defined danger zones around the vehicle.
2. Intelligent Identification
The system identifies: Pedestrians, Vehicles approaching, Objects or obstacles
3. Instant Alerts
Operators receive visual alerts inside the cabin and audible alarms when a risk is detected.
4. Early Reaction Time
Alerts activate before collision risk becomes critical, allowing safe corrective action.
5. Event Logging (Optional)
Alerts and events can be logged via telematics for safety audits and reporting.
