Public retail buildings such as fitness clubs for example are becoming more and more popular. Many of them are unstaffed for a large portion of the day. For example this is a gym that we worked on in late 2009. It is unstaffed for most of the day during which there is an access system for members to use to enter the club. This keeps track of exactly who enters the club and when. Paired with surveillance cameras positioned all around the gym, it provides total control for the owners as far as access, as well as recorded video footage in case of any accidents.
