The KVM that never goes dark.

When the OS is dead, software can't save it. The CEC KVM line watches the video signal and presses the buttons, so a crashed, frozen, or unbootable machine is still on your graph.

Out of band. Zero apps installed on the PC. Alive on standby power, reachable over your mesh like any other device you own.

The demo · simulated, but this is the real sequence

2 a.m. Blue screen. Nobody drives anywhere.

The machine's own OS agent goes silent, the KVM takes over on standby power, and a CEC Support session that you approve reads the screen, cycles the power, and watches it come back. Press play.

The KVM streams to your devices over the mesh, end-to-end encrypted. A technician only ever joins with your approval: logged, watchable, revocable.
How it wires

Eyes on the video. Fingers on the buttons.

Four connections, all of them dumb on purpose. The PC can't tell the KVM from a monitor and a keyboard, which is exactly why it works when nothing else does.

Latency is the difference between watching and driving.

Same job at every price: keep the machine on your graph when its OS can't help. They differ in how sharp they see and where they live.

With the app

It's just another node on your graph.

No second app, no vendor portal. A KVM claims into your fleet like any laptop: its console opens in the same tab, its power button is a button in the drawer, and sharing it follows the same grants as everything else.

  • Claim it with the same one-tap adoption as any device
  • Streams ride your mesh, end-to-end encrypted, with relay only when needed
  • No second login: approved mesh peers open its console directly, no port forwarding, no exposed web page
  • Works without us: CEC KVM, CEC's open firmware fork. No account, no subscription

Out of the box, it's already calling you.

A fresh KVM announces itself on your LAN before it knows the time, before it's touched the internet. Your app hears it, you tap Claim, and it's wearing your name.

01 · on power

It calls out over mDNS on a claim channel that never leaves your network. Clock-free: it works before NTP.

Every device of yours on that LAN shows the newcomer instantly. No IPs typed, no cloud round-trip.

It appears in your claim sheet. Tap Claim, done. Attach it to a machine and it renames itself to match.

The fine print, in large print

A box that can press your power button should answer hard questions.

keys

Connection keys are made and stored on the device, never on a CEC server. Nobody at CEC can connect on their own.

streams

Video travels directly between your devices, end-to-end encrypted. A relay, when needed, only passes data it can't decrypt.

sessions

Repair sessions start with your approval, every action is logged, and you can watch live or revoke at any moment.

ownership

Firmware and software are open source and self-hostable. No subscription is ever required to use your hardware.

In stock · shipping now

Fix it even when it won't boot.

CEC KVM Go is coming soon. Internal is for the rig you're building; Pro is for the desk. Orders ship through Critical Error Computing.
