Start with an audit of cabling, entrance panel, stations, power, risers and lock. Existing conductors may sometimes remain, but audio, image, accessibility, names, credentials and operation without internet must be resolved together.
Key points
- Test every riser and apartment.
- Separate local operation from cloud options.
- Include the door and lock.
- Plan access and migration by riser.

Station or app
A wall station works locally without a smartphone; an app offers remote answering but needs internet and accounts.
Retain local operation and manage account transfer.

Often after testing and depending on technology.
Can the app replace every station?
Sometimes, but a local station is more inclusive and independent.
Can intercom video be recorded?
Only where necessary and handled under applicable data rules.
Must the lock be replaced?
Only when condition or compatibility requires it.
