Come home.
With your Key.
Start with your door. We’ll help define what a Presence-ready entrance would need.
Your entrance.
Planned properly.
A personal Key, a compatible reader and the right connection to your door or gate. We scope the intended setup with the installation and everyday fallback in mind.
Discuss your homeWhat does the setup include?
The intended setup combines personal Keys, a compatible Presence reader and suitable electronic access hardware. Your door, lock or gate controller, power and connectivity need to be assessed before compatibility can be confirmed.
Can I buy a ready-to-fit kit?
Residential access is in development. A universal retrofit kit is not offered here. Hardware, installation, supported services, timing and pricing are confirmed for the specific property.
What about a lost Key or a power cut?
Alternative entry, revocation and independent emergency escape must be planned with the installer. The setup must never rely on a single digital path for safety.
A larger property
or several locations?

About availability and your request
“Pre-order” means a request to reserve release interest or discuss a project, not a purchase order or contract of sale. Planned arrival in 2027 is a current target, not a guaranteed shipment, installation or service date. Timing, specifications, supported integrations, regional availability and pricing may change. Your request does not guarantee allocation or delivery, and you have no obligation to buy. Final details and any purchase terms will be provided separately before you decide to place a binding order. You may withdraw your request by contacting 4SI.
For software, 2027 refers to the planned product rollout associated with these offerings; existing web access is separate. Installation and Enterprise deployment are confirmed per project.
