In this case the cost seemed to apply in part to 3,000 cameras. But solely based on the article, it's hard for me to tell what portion of that $30 million went to upgrades/maintenance and what portion went to the cameras. However it does clearly say it would be another $7 million to maintain the cameras over the next four years.
