S-103Physical security — Intercom Systems
Intercom Systems
Door entry that ties into access control, not a separate box.
An intercom is the one system every visitor touches, and in most buildings it is the oldest thing on the wall. Modern panels put video on a phone, unlock the door remotely, call the elevator, and log every entry — and when they share a directory with access control, tenants stop having two credentials for one door.
AWhat the install covers
- Video entry panels for lobbies, garages, and service entrances
- Apartment and tenant directory configuration
- Remote unlock and visitor calls routed to a phone
- Elevator call integration where the building supports it
- Integration with access control so entry logs land in one place
O&MAfter handover
What we keep doing once it works.
Included in a management agreement. Without one, this is the part that quietly stops happening the day the installer drives away.
How managed service works →- Tenant directory kept current as units turn over
- Panel and station health monitoring
- Firmware updates and hardware replacement
QCommon questions
Intercom Systems, asked and answered.
- Can an intercom work with our access control?
- Yes, and it should. When the intercom and access control share a directory, tenants have one credential instead of two and the lists cannot drift apart — which they otherwise do within about a year.
- Can residents answer the door from their phone?
- Yes. Video entry calls route to a phone, so a resident can see and speak to a visitor and unlock the door without being home.
- Do you replace old intercom panels in pre-war buildings?
- Regularly. The usual question is whether existing wiring can be reused, which decides most of the cost. That is established during the survey rather than assumed.
- Can the intercom call the elevator?
- In buildings whose elevator controller supports it, yes — a visitor can be admitted and the car sent, which matters most in buildings with restricted floor access.

Every job starts with someone walking the building.
A site survey costs you nothing and produces a real drawing — device counts, cable paths, and a fixed number. Not a brochure.
