as I understand it they have competitors for individual aspects of what they offer, but no-one else offers a complete end to end solution with the depth of offering CPZ has. Also the other issue is the significance of the TCP deal, as this will give them management rights over circa 1000 car parks in which they would have the potential option to deploy their technology.

I can't be sure, but I think this might make them larger than Wilsons in terms of car parks under management, and in the UK, you can be fined for overstaying a parking limit period on private property, which is where the reporting and infringment/revenue share model comes into play - especially when you roll your technology out to large numbers of sites that you have under your management.

I think that they still require the approval of the shopping centre owner/head tenant (read Tesco, Sainsbury etc) to deploy the technology on a site by site basis but given the lack of parking availability and infrastructure, the shopping centre owners/head tenant actually want the car parks turning over as this means more shoppers get to the shops, resulting in increased turnover, and a better shopping experience. At the end of the day, they are probably only pinging a small % of the actual offenders, but say 15 fines/tickets per day per site soon adds up to a lot of revenue when you have large numbers of sites which you control and you are getting a % of each infringement.
