Small can be a big deal, especially when it comes to smaller access control systems.
Users expect the basics but often need more doors covered or more features added later on. As compared to large enterprises, there may be less expertise, staff, resources and time to maintain the system. Rip and replace, sometimes a budget option with big designs, is not possible down the ladder, so users often seek ways to mix legacy with new controllers for a solid return on investment. There is sometimes a need for a system to accommodate a diversity of readers from keypads and keyfobs to cards and badges. And who can resist the ability to interact with the access system through a smartphone or over a Web browser?
