The basic sequence
A person presents a card, fob, phone, or PIN. The reader sends it to a controller. The controller checks whether that person is allowed at that door at that time, then releases the lock and records the event.
The main parts
- Credentials: cards, fobs, mobile, PIN
- Readers at the door
- Controllers in a secure panel
- Locks, strikes, and exit hardware
- Software, on-site or cloud
Doors report back
Door contacts tell the system if a door is forced or held open. Request-to-exit devices tell it someone is leaving so it does not raise an alarm.
Cloud vs on-site
Cloud systems let you manage from a browser or phone. On-site software keeps everything on your own server. Both use the same door hardware.
