Bolt.Access
Doors that don’t need the internet to do their job.Two doors per controller. Eighteen on one cable.
One controller runs two doors, from the front lobby to the loading bay. You run them all from one app, and nothing rings you at 2 a.m. to say the server’s down, because there isn’t one.
Every BDC2 is the same hardware. The one that sees ethernet runs the site; up to eight more reach it over wireless mesh. No Windows server to build, nothing to install on site, and a claim code to commission it.

Bolt.Reader and Bolt.PINReader
Tap a card, a phone or a code. Two readers. Every credential.
A slim reader for cards and phones, and one with a keypad for the doors that want a code too. Both match the rest of the kit. OSDP v2 with secure channel, IP65, single-gang or surface. Existing HID Signo readers stay on the wall, and Bolt.W2O brings Wiegand readers onto the same bus.

Offline-first
The broadband goes down. The doors don’t.
Every controller holds its own credentials, rules and schedules. If the internet cuts out, the doors carry on deciding who comes in, and events catch up when the line comes back. Nobody waits outside in the rain. Doors, users and schedules are set in the cloud and held on the controller. When the customer’s broadband drops, the controller carries on, and events queue until the line comes back. That’s a 2 a.m. call you don’t get.
Whatever lives in their pocket. One controller. Every way in.
Same controller, same app, whichever way in. Sometimes that’s a phone, sometimes a card, and sometimes a code for the window cleaner. Every credential runs through the same readers and the same controller. Nothing extra to wire for phones, QR codes or visitor passes.

Schedules that understand how buildings actually work. Rules held on the controller, not on a server.
Roles, time bands and one-off exceptions, in plain words anyone in facilities can read. Each site keeps its own time zone, so the clocks change when they should. Roles, time bands and exceptions, set in the cloud and held on each controller, in each site’s own time zone. Plain enough that the customer changes them without ringing you.
| Who | Door | When |
|---|---|---|
| Everyone | Front door | Mon–Fri, 07:00–19:00 |
| Cleaners | Rear entrance | Daily, after 18:00 |
| Delivery driver | Loading bay | Thursday 14:00, once |
| Facilities | Plant room | Any time |
Example rules, not a real site.
Nothing in a cupboard to look after.
Controllers set themselves up the moment they see the internet. No Windows server, no VPN, no dongles, no holes in your firewall. Your installer fits it and looks after it, and you deal with one name.
Bolt.Access BDC2
No server. No VPN. One cable.
Enter the claim code from the box and the controller joins the customer’s account. One controller takes the ethernet; the rest find it over Bolt.Mesh, three hops at most, and route round one that drops out.

Speaks to your stack
Nobody buys everything from one vendor, so Bolt doesn’t expect you to.
- Akuvox intercoms Available now Video intercom at the entrance, Bolt credentials behind it.
- HID Signo readers Available now Existing OSDP readers stay on the wall.
- REST, MQTT, webhooks Available now For everything else. If it speaks HTTP, it speaks Bolt.
- Microsoft 365 Planned Staff and groups synced from the directory, so leavers lose access when IT removes them.
- Google Workspace Planned Same again, for the other half of the country.
The paranoid stuff, done quietly
We did the boring engineering so you don’t have to think about it.
- Every command to a controller is signed (HMAC-SHA256) and carries a fresh nonce, so a replayed message is ignored.
- Firmware updates are signed and verified on the controller before they install.
- Readers talk OSDP v2 with secure channel, so the cable to the reader isn’t an open door either.
