Physical security is a critical operational element for companies and organizations both in the public and private sectors that requires a high degree of accuracy, scalability, and operational efficiencies for incident handling. Traditional camera-based systems have continued to serve their purpose well for years, but they have limitations that can create security gaps, increase costs, and waste valuable resources if not optimally configured for alarm events. 3D LiDAR solutions, however, can overcome these limitations to increase effectiveness and reliability, reduce false alarms, and improve operational efficiency.
