Changing a building's classic door entry system for a video door entry system is one of the improvements most requested in residents' associations, and its quote has more items than it seems at first sight.
Outdoor panel and camera
The video door entry outdoor panel includes a camera, push-buttons per flat and, in many current models, opening by card or code as well as the bell itself. Its location and resistance to weather and vandalism are factors that determine the model to choose in an entrance open to the street.
Cabling: reuse the existing or run new
In many buildings, the cabling of the classic door entry system (two wires) is not compatible with the demands of a modern video door entry, which often requires more wires or specific cable to transmit video with quality. Checking whether the existing cabling can be reused or new cabling has to be run to each flat is a decision that changes the total quote a lot.
Monitors in each flat
Each flat needs its own indoor monitor, replacing the classic handset. If WiFi monitors connected to a mobile app are chosen instead of a physical wall monitor, the installation needed changes and the internal cabling of each flat is often simplified.
