Local-first by design

The house keeps working even when the internet doesn’t.

Sentri is built around services that run at the property. Cameras, recordings, event history, security state and the policy engine do not need a remote service to remain the source of truth. Remote access and notifications can still leave the house when enabled.

Sentri security reasoning

Combines event evidence, location, recent context, security mode and deterministic policy before anything sensitive is allowed to happen.

IGNORE OBSERVE NOTIFY DETER
OPTIONAL REMOTE SUPPLEMENTAL
Mobile notifications Important events can be surfaced away from home without becoming the system’s source of truth.
Secure remote access Reach the local system when away. Losing that path should not stop local recording or policy evaluation.
Selective external services Cloud or outside AI can be used where useful without replacing the local security architecture.
Remote is an extension, not the foundation.
The property remains the authoritative place for security state, event evidence and core policy.
Core path stays local. Remote features can disappear without changing what the property recorded or decided.
