Welcome to SILAS OS.
Our SILAS operating system allows you to easily issue bluetooth passes to any user you choose for any lock they need access to. Set time restrictions for which days or what times they can access your locks, giving you complete control from your fingertips.
Why SILAS
Three reasons to retire your keys.
Our SILAS lock fits onto your existing door and turns it into a connected, accountable entry point for your home or business.
Know who opened your door, and when
Every entry and exit is logged with identity and timestamp — a complete, tamper-evident audit trail for your premises.
Remote access without handing out keys
Unlock doors from anywhere, or issue one-time passkeys to guests, contractors and deliveries. Revoke access instantly.
Workforce entry analytics
See which staff entered or exited, when they arrived, and how your spaces are actually used — exportable for HR and operations.
The hardware
One lock. Fitted to your door. £120.
Our SILAS lock is a one-time hardware purchase that retrofits onto standard doors in minutes. It pairs with our cloud platform so you can manage access, issue passkeys, and review analytics from any device.
- Tamper-resistant build with battery backup
- Works alongside your existing keys during transition
- Encrypted communication with the DSFABW cloud
- Compatible with iOS, Android and web dashboard
The software
SILAS OS runs on your mobile device (iOS and Android) and from your web browser. With our encrypted cloud communication you can issue passes, remote unlocks and track audit logs for each lock.
SILAS OS lets you create your own organisation, invite users and set parameters such as time / date / usage points giving you complete control over who, when and how someone accesses your door.
