An access control system decides who can open which door and when. Instead of copying keys, a business issues credentials that can be added, removed and tracked. Understanding the parts helps you compare quotes and plan a system that can grow.
The main parts
- Credentials: cards, key fobs, PIN codes or phone-based credentials that identify a person
- Readers: devices at the door that read the credential
- Controller: the device that checks the credential against the rules and tells the lock to release
- Door hardware: electric strikes, magnetic locks or electrified locksets that physically secure the door
- Power supply and backup: so doors behave predictably during a power failure
- Software: where users, schedules and door permissions are managed and events are logged
What a day looks like
Someone presents a card. The reader sends the number to the controller. The controller checks whether that card is allowed through that door at that time and, if so, releases the lock for a few seconds. Every event is logged, so you can see who used which door and when.
Why businesses switch from keys
Lost keys mean re-keying locks. With card access, a lost card is deactivated in the software. You can also give contractors or cleaners access only during set hours, and review door activity afterward.
Safety and code points
Doors on an exit route must allow people to leave freely, and electric locks are normally required to release on a fire alarm signal. This is governed by building and fire codes, so the design should follow them. It is one reason access control should be planned and installed by a qualified team.
