and analysis, seamless integration with existing infrastructure, and simple system management. The LiDAR-based security and surveillance solution provides numer- ous important benefits for the recent se- curity application.
High accuracy, even in adverse condi- tions. LiDAR offers a superior level of accuracy compared to alternative tech- nologies. In the recent security applica- tion described above, the LiDAR solu- tion boasted 95% accuracy. In addition, LiDAR sensors maintain their reliability and high performance even in extremely bright or low light conditions, and in ad-

verse weather like wind or rain.
Low rate of false alarms. The intelligence and reliability of a LiDAR-based solu-
tion significantly reduces the rate of false alarms in security applications, ultimately saving time and costs. Customers have experienced a reduction of false alarms by up to 84% compared to using cameras alone. The low rate of false alarms provides security personnel with confidence in the reliability of the alerts, improving the quality and promptness of their responses.
Easy-to-manage, fully automated solution. Some LiDAR-based surveillance solu- tions use machine learning and 3D perception algorithms to scan the sensor’s field of view, analyze point cloud data, and provide metadata on detected individuals. Intrud- er location information from the LiDAR system can be used to automate PTZ camera movement so that intruders are detected and tracked visually from the moment of tres- pass. This fully automated security solution is both cost-effective and easy to manage.
Real-time tracking and analysis. With a LiDAR-based solution, security data is available in real time. The solution automatically tracks individual people and pro- vides real-time location information, enabling security staff to quickly locate and re- spond to potential threats.
Cost-effective deployment. In addition to unparalleled levels of accuracy, a LiDAR- based solution is also extremely cost-effective. Some LiDAR sensors can provide a 360-degree field of view, which means far more area can be covered with each device compared to other sensing technologies. With fewer devices to install and maintain, a LiDAR-based system saves time and costs.
For example, in a recent security application, a port in South Korea needed to upgrade its security systems to improve security and reduce false alarms. The port’s existing camera-based systems and traditional intrusion prevention technology did not pro- vide the necessary awareness to protect critical security facilities. A more accurate and intelligent solution was needed to reliably identify and respond to potential threats. In addition, the port required a fully automated surveillance solution with a low rate of false alarms that could deliver consistent results regardless of environmental con- ditions. Furthermore, the solution needed to integrate effectively with their existing systems.
Port authorities had used several different perimeter security technologies in their challenging outdoor conditions, including CCTV, infrared sensors, and tension sen- sors. However, these technologies were unable to maintain the extremely high levels of accuracy that the application required, and environmental factors like wind and rain caused frequent security failures. False alarms were especially costly, wasting valuable time and resources to respond to nonexistent threats.
Port authorities ultimately selected a highly intelligent and combined hardware and software platform solution consisting of PTZ cameras and LiDAR sensors with artificial intelligence perception software. The LiDAR based solution provided 95% accuracy and a complete 360-degree view of the secured area in any light or weather condition with the ability to detect, track, and classify objects based on the rich point cloud data received from the LiDAR sensors. The solution integrated effectively with the customer’s existing systems, including their VMS. The solution also included a dashboard for at-a-glance visibility into all regions where LiDAR sensors are installed.
As technology advances, security and surveillance must keep pace to reduce false alarms and improve the protection of sensitive areas. Cameras will
always play an important role in any physical security strategy. But
adding LiDAR technology provides an extra layer of protection
while empowering security personnel to do their jobs more effec- tively.
