Just looking at the LIDAR technology proposal being worked on for commercialization, I wonder if it may suit a country looking to protect it's border from intrusion by people and/or drugs being smuggled in from a neighboring country? Might be cheaper and more effective than a wall in some terrains?
This quote is copied from a recent release by the Company.
"The LIDAR systems are a highly advanced surveillance system that utilise state-of-the-art light detection and ranging technology. The device enables highly accurate intrusion detection and is capable of alerting security breaches with an extremely high level of accuracy across large and remote perimeters both during the day and at night.
The ability to incorporate thermal cameras to the LIDAR sensing system allows greater reliability for detection of intruders. We consider the combination of the thermal and LIDAR technologies running on the Spectur’s cloud platform and powered by solar will be a world first. The application will enable the securing of
large perimeters without the traditional limitations and costs associated with
laying infrastructure including power and communication cabling."
