"We are in more than 2,000 veterinarian practices from Canada to Hawaii," said Brookes Bruno, CaerVision's senior executive and director of sales. CaerVision installed the two TVs and provided a warranty as a service to the shelter. The company charges about $100 per month for service agreements and videos.
