LEXSO is Constellis' next-generation operational intelligence platform, designed to extend visibility, accelerate decision-making, and enhance mission effectiveness. Leveraging AI and multiple sensing modalities — such as lidar, radar, thermal imaging, acoustic detection, and video analytics — LEXSO fuses data into a single, actionable operating picture in real time. Ouster Gemini will serve as the foundational intelligence layer of LEXSO, leveraging Ouster's proprietary AI software to process 3D digital lidar data for real-time analytics, threat classification, and automated response protocols to bring Physical AI to advanced security operations.

Purpose-built for both public and private environments, LEXSO delivers early detection and actionable threat alerts, giving operators the intelligence to respond instantly. Its open architecture integrates seamlessly with existing systems, ensuring that intelligence moves fluidly from the field to the decision-maker without delay. Backed by Ouster's lidar-powered AI capability, LEXSO also delivers:

• Advanced 3D situational awareness and object tracking across challenging weather and light conditions
• Reduced false alarms
• Autonomous threat assessment and response coordination
• Improved operational efficiency and more informed decision making

"Constellis' deep operational expertise, network, and reputation make them an invaluable partner in deploying Ouster Gemini for critical and large-scale security operations," said Ouster CEO Angus Pacala. "Our deployment with LEXSO underscores how lidar-powered AI can transform situational awareness and decision-making for the most demanding security environments."

"Ouster's software-defined approach to lidar is the perfect complement to LEXSO's open architecture," said Terry Ryan, CEO of Constellis. "Together, we're turning disparate signals into actionable intelligence that moves from the field to the decision-maker in real time — raising detection performance, reducing false alarms, and accelerating response across mission-critical environments."
