Types of Access System
There are several different types of Access Control System on the market and these can be defined into 3 basic types.
Simple Audio Video
These types of system are of the simplest design and easiest to install, they are usually only used when one or two doors need controlling.
The system would consist of an outside panel which could have a simple press button and audio device that will ring a telephone type handset within the building and the operator can then release the door to the visitor.
These units can be fitted with a keypad or proximity reader so that authorised personnel can let themselves in. these systems can also be fitted with a small camera and the internal handset will have a monitor, so the operator may see who they are talking to.
Standalone System
The simplest standalone system will have a keypad or proximity reader adjacent to the door it controls. Its equipment is located near to the door on the secure side. Authorised users gain access through the door by inputting their code or presenting their card or tag to the reader.
Networked System
These systems are usually recommended when there are more than 3 doors in use and the benefits of a PC based network system are far superior to the two other types of system above.
The system can log who is in the building, what time they entered and left, control different doors at different times and days and limit certain people to certain areas.
Networked systems are modular and can be expanded to many hundreds and even thousands of doors in separate buildings in separate geographical areas and even countries. The system can be controlled from one central point or mobile via smart phone or Tablet.
