I have spoken to the supplier of our red light cameras regarding this and it appears that the problem is associated with led heads. They have apparently developed an interface but have to obtain the necessary Approvals from the individual head manufacturers. From previous experience this could take some time.

My understanding at the moment is you can not upgrade to an ELV controller if there is a camera on site.
