Pedestrian versus forklift
A crossing where the aisle meets the walkway. A keep-out distance between the two classes, armed all shift, with a beacon that reacts before anyone reads a message.
Alert type 03
If anyone comes closer than
X metres, fire.
A virtual tripwire drawn on a camera that is already installed. Select a point or a region, calibrate it once against a distance you know on the floor, and set the threshold. livee then tracks approach in real units — pedestrian-versus-forklift keep-out on a crossing, a press, a charging bay, a high-value cage.
Calibration
How pixels become metres.
This is the part worth understanding before you buy, so here it is plainly.
You give it one known distance
A rack pitch, a bay width, a painted line, a pallet edge — something on the floor whose real length you can state. You draw that same span on the image.
livee derives the floor plane
From that reference and the camera's view it builds the relationship between screen position and ground distance, so a threshold you set in metres means metres.
You set the threshold
Three metres to the cage. Two to the press. Whatever your risk assessment already says — livee does not invent the number, it enforces the one you chose.
We check it together
On the demo we walk the actual distance in front of the actual camera and compare it to what livee reports. If the view is too oblique or too far for the accuracy you need, you will hear that from us first.
Where it earns its place
Four keep-outs that already exist on paper.
Most sites have written these rules down already. This is the part that notices when one is broken.
High-value cage
A marked point on the cage, a three-metre threshold, class person, armed outside picking hours. SMS the floor lead, POST to incidents.
Machine and press
An exclusion radius around equipment that should not be approached while it runs — the rule your risk assessment already contains.
Charging and hazmat bays
Battery charging, gas bottles, a decanting point. Distance rules that nobody can enforce by watching a monitor.
Honest about the measurement
What the number is, and what it is not.
- It is image-based measurement from a calibrated view — not lidar, not a laser curtain, not a safety-rated device
- Accuracy depends on the camera angle: an oblique view along a long aisle is less precise than one looking across it
- It measures to the marked point or region, on the floor plane you calibrated
- It is an attention layer. It does not replace guarding, interlocks or a safe system of work
- We walk the distance with you on the camera you intend to use, before you rely on the threshold
- If the view cannot carry the accuracy you need, we say so rather than shipping a number you would trust
A tripwire you can move with a mouse.

About proximity alerts.
Is this a safety device?
No, and we will not let it be sold as one. livee is an attention layer that notices a keep-out being broken and tells people and machines about it. Safety-rated protection — interlocks, guarding, light curtains — is a different category of equipment with a different certification, and livee does not replace any of it.
How accurate is the distance?
Accurate enough to enforce a three-metre rule on a reasonable camera view, and we prove that on your camera during the demo by walking the distance. Precision falls off with oblique angles and range, which is why we calibrate on the specific view rather than quoting a single number for every site.
Can the threshold differ by object class?
Yes. A forklift keep-out and a pedestrian keep-out on the same crossing are two rules on one camera, with different distances and different channels.
