Another specialty under the low voltage umbrella is security systems. Security systems, audio visual, structured cabling, and phone systems all run on what’s called “low voltage.” It is obvious by its name to be “lower voltage” than standard – which would be electrical outlets you’d plug appliances into, for example.

Security systems today feature advanced features to authenticate users and give access to individuals from employees, to clients, and customers. You can setup permissions with many variables, allowing certain access to the building/room for only certain individuals, at certain times of the day. In addition, the authentication methods used today are more advanced than waving a key fob or card to gain entry to a room.
