The model is a starting point for review. Door hardware, cable route, power and mobile workflow still need to be confirmed.
Use the outdoor station, indoor monitor and lock interface as one reviewed entry path.
Measure the monitor-to-station and station-to-lock distances and confirm the available voltage.
Specify the model, packaging, app, documentation and destination market in the written quotation.
Keep the four-page model document with the installation brief so the connection, lock and packing-list assumptions stay visible during review.
