| Our Small SID is designed to monitor vehicle speeds and display them on a highly visible LED screen. When vehicles exceed the programmed speed limit, it instantly signals "SLOW DOWN," encouraging safer driving behavior. With its lightweight and portable design, the Small SID can be easily relocated to different locations, reducing costs while maintaining effectiveness. Choose between mains or solar power options and flexible pole or wall mounting to suit your specific needs. Elevate road safety with the Small SID, making our roads safer for drivers, cyclists, and pedestrians.
