To whom it may concern:
This letter is being sent in response to your request regarding the Opticom™ priority control system. Opticom is manufactured by Miovision Technologies US, LLC. Since 1968, Opticom has been the standard in priority control, now totaling more than 3,100 customers, 90,000+ intersections and 90,000+ vehicles worldwide.
Worth noting, Miovision’s Opticom system is used in 48 of the 50 largest U.S. cities, amongst many other deployments in Canada, Europe, Asia-Pacific and the Middle-East.
Miovision invests heavily in research and development, to ensure its customers always receive the best value and most feature-rich solutions when buying priority control. This effort has led to more than 100 patents, either granted or in-process.
While the topic of a mixed system sometimes emerges, please note that Miovision designs, develops and tests each Opticom component as part of a “matched component system. ” This means that “mixing” non- Opticom components raises concerns, including:
• Security is accomplished through Opticom’s proprietary design, which prevents unauthorized use of the system. Mixing components would significantly reduce or even eliminate the security measures Miovision has built into the Opticom solution • Mutual aid to and/or from surrounding communities depends on compatibility amongst signal priority solutions. The use of Opticom components with non-Opticom components has not been designed for or tested by Miovision
Proper testing of compatibility would require inclusion of all of the potential operating scenarios (temperature, humidity, electrical and accelerated life) and third-parties. Further, testing would need to be repeated each time an Opticom or third-party component was updated, making testing impractical. While the Opticom matched component system is guaranteed, mixing Opticom components with non-Opticom components voids the warranty of the connected Opticom components and transfers the liability of any such incompatibility from the manufacturer to the customer
• The Opticom model 764 phase selector is not compatible with other brands’ GPS emitters • The Opticom Central Management Software is a proprietary software program for the Opticom system that is not compatible with any other vendor’s equipment or software
For the above reasons, Miovision strongly recommends keeping the Opticom system whole.
In the state of California, DDL Traffic is the authorized dealer for Miovision. There are currently no other authorized dealers of Miovision’s products in California and Miovision is the sole-source provider/manufacturer of Opticom products.
Please contact Miovision or DDL Traffic if you have further questions or if you require additional detail.
Miovision and/or DDL Traffic will also provide a list of references if you’d like to talk with others about this topic.
Sincerely,
Kyle Anderson
