When Ci and its partners devised the perimeter and parapet signage system now in use at the MCG and Etihad, there were a number of unique challenges that needed to be met and there was nothing available off the shelf that would do. The hugely successful LED project that you see today combined fresh engineering, factory customization and control programming of the highest order. It is not something that could have been achieved by an ordinary signage company.
When you watch Australian Rules football on TV, the differences between the LED signage at the various venues is apparent. Some stadiums have signage missing a lot of pixels, some have signage with a disconcerting gap at the bottom and all of them other than the MCG and Etihad have signage that cause problems for the TV cameras. It's not just a matter of pixel size but refresh rate. As for the ability to adjust for shadow and sunlight, that's another story entirely.
If you want LED signage for your stadium regardless of size, Ci is an extremely safe pair of hands.
