Beacon or siren
The amber light over a crossing, a lamp at a pack station, an audible in a cold store. The most common first wiring, because it is immediate and reversible.
Channel
The floor reacts
before anyone reads anything.
Email and SMS reach people, and people take time. Some events should not wait for that. livee can put a signal on your local network the moment a rule fires — to a PLC, a beacon over a crossing, a siren, a door controller or an industrial PC — so the physical response happens while the message is still being delivered.
What it drives
Things on the floor that can be told.
livee does not control your process. It sends a signal; what the equipment does with it stays your engineering decision.
PLC or line controller
A signal your automation already knows how to read, raised by a rule you wrote against a camera view.
Door or gate controller
A yard gate, a roller door, a turnstile. The event becomes an input to equipment that already has a control system.
Industrial PC
A local machine that owns the response — a display at the dock, a supervisory station, a panel on the wall.
Boundaries
Where this channel stops, deliberately.
- It signals. What the equipment does with the signal is designed and owned by you
- It is not safety-rated. Interlocks, guarding and light curtains are different equipment with different certification
- It runs on the local network, so an on-site deployment is often the natural fit
- It fires in parallel with the other channels — the beacon does not wait for the email
- It is per alert, so only the rules you choose ever reach the floor
- Integration is scoped with your engineer, not assumed — we ask what the equipment expects before promising anything
A worked example
The crossing that lights itself.
One camera, one rule, two channels — the sequence customers ask for most often.
The rule
On CAM-21, a proximity alert between the forklift class and the pedestrian class at the crossing, armed for the whole shift.
The machine signal
Ethernet to the beacon controller. The light goes amber the moment the distance closes, with no human in the loop.
The human signal
In the same second, an email to EHS with the clip. Not to make anyone act — to make the pattern visible when the month is reviewed.
What it is not
It does not stop the forklift. It warns, and it records. Stopping machinery is the job of equipment built and certified for that.
A signal in the same second, no human in the loop.

Which protocol does it speak?
That depends on what your equipment expects, which is why this channel is scoped with your engineer rather than sold as a checkbox. Bring the controller's documentation to the demo call and we will tell you plainly whether it is a fit.
Can it stop a machine?
livee sends a signal; it is not a safety-rated device, and we will not position it as one. If something must be stopped for safety, that belongs to certified equipment designed for the job.
Does it work in the cloud deployment?
A local signal wants a local presence. Sites that lean on this channel usually run the on-site deployment, which is also often what their security policy prefers.
