Access control
Comparison guide
Access control or intercom: what does your building actually need?
Access control manages who is allowed through a door. An intercom manages how a visitor requests entry. In many commercial and multi-tenant buildings, the right solution is both: access control for authorized users and an intercom for visitors, deliveries, and exceptions.
Intercom
Best for visitors, deliveries, and situations where someone must verify before opening.
Combined system
Often the best approach for shared entrances, multi-tenant buildings, and commercial sites.
Difference
They do not solve the same problem
Access control answers who is allowed to open a door, at what time, and with what credential. It is about permissions, schedules, users, and history.
An intercom answers how someone without a credential requests entry, and who decides whether to unlock the door. It is about visitor handling and verification.
Simple rule
Use access control for known users. Use an intercom for visitors and exceptions.
Use cases
When each option fits
Access control versus intercom
| Need | Best fit | Why |
|---|---|---|
| Employees or tenants need daily access | Access control | Users enter with credentials and schedules. |
| Visitors need to request entry | Intercom | Someone can answer, verify, and unlock. |
| Shared main entrance | Both | Known users enter directly while visitors use the intercom. |
| Back door or technical room | Access control | Visitor communication is usually not needed. |
Design
What to decide before quoting
Door count
Count main entrances, back doors, garages, and restricted rooms separately.
Visitor flow
Clarify who answers visitors and what happens outside business hours.
Credentials
Badges, fobs, mobile credentials, PINs, and schedules change the system design.
Remote management
Some buildings need managers to update users or unlock remotely.
Camera coverage
Video at the door may be useful even when the intercom is audio-only.
Existing hardware
Door hardware and wiring can strongly affect installation complexity.
FAQ
Frequently asked questions
Short answers before the site visit or quote step.
Can an intercom replace access control?
Usually no. It helps visitors request entry, but it does not replace controlled daily access for authorized users.
Can access control unlock from an intercom?
Often yes, if the system is designed and wired for it.
Do all doors need both systems?
No. Main entrances often need both, while back doors and technical rooms may only need access control.
What should I send for a quote?
Send the number of doors, entrance type, visitor flow, existing hardware, and whether remote management is needed.
