Laser alerts and active countermeasure systems are not interchangeable. Coverage, installation, vehicle geometry, maintenance, and local rules all matter.
Define the system
Separate detection, alerting, active response, control, and professional installation requirements.
Treat placement as engineering
Vehicle profile, sensor field of view, alignment, wiring, and service access affect the plan.
Check the law
Rules differ by jurisdiction and vehicle type. Use current official sources before purchasing, installing, or operating any countermeasure.
