| Ingressus Controller and Slave Terminals | 
| Centralized IP Access Control Topology | 
|  | 
| A single controller can control multiple doors, thus reducing cost per door for large-scale installation. | 
| When servicing more doors, the capacity of the controllers are fully utilized, making the most out of your investment. | 
| Only minimal number of hardware need to be installed on-site as the controller only needs to be set up once. | 
| Centralized, all data are kept in one single location, making it faster to process large amounts of data from different locations. | 
| Monitoring can cover bigger areas as it is better suited for large-scale implementations. |
