1. Compare everyday convenience
A card is presented to a reader; a PIN is entered on a suitable keypad. Smartphone access needs supported functionality and setup. Hikvision lists card, PIN, Bluetooth, Hik-Connect and indoor-station release for the DS-KV6124-WBE1, for example. This applies to that model, not every intercom. Consider what children, older relatives and changing staff will find easy to use.
2. Agree permissions and responsibilities
List who needs access to each door and who administers the system. Ask how lost cards, staff changes and replacement phones are handled. If a visitor should enter only temporarily, the chosen combination must support that restriction. Avoid unnecessary sharing of personal credentials, which complicates later attribution and changes.
3. The door is part of the system
The reader and app are only the controls. The existing lock, electric release, power supply and operation from inside also matter. Discuss behaviour during power or internet outages and a suitable fallback. For several doors, ask for an explanation of separate controls. Have the components assessed together before buying individual devices.
