Sole Source Letter

This letter confirms that the OverWatch™ solution is a sole-source product designed, manufactured, and sold exclusively by 4Sight Labs Inc. The OverWatch solution is only available directly from 4Sight Labs Inc.

The OverWatch sensor body is a unique blend of polycarbonate designed to withstand harsh impact, offer long-lasting durability, and is waterproof. The unique looped-through sensor design allows wearing on wrists and ankles using hypoallergenic bands that are reusable and disposable.

Leveraging proprietary long-range wireless sensors, OverWatch continuously monitors critical vital signs such as heart rate, oxygen saturation, and skin temperature for detainees and inmates. When an individual's biometric readings indicate a potential wellness concern, OverWatch sends real-time notifications to designated personnel, enabling timely intervention to prevent medical emergencies and lethal events.

To the company's knowledge, no other modular, wireless, mobile platforms can provide real-time health monitoring of detainees and inmates at this scale with little to no hardware installation other than plug-and-play devices. Provisional patents and proprietary software and hardware further secure OverWatch's capabilities.

The OverWatch solution uniquely fills a critical gap in the correctional wellness environment by enabling proactive monitoring, intervention, and improved outcomes through its innovative integration of biometric sensors, wireless connectivity, and cloud analytics.

Sincerely, David Sanders CEO, 4Sight Labs
