A safety projector that is always on becomes wallpaper. Add a detection sensor and it stays dark until a truck backs to the door, a forklift turns into the aisle or a person steps onto the crossing, then the warning appears exactly when it matters. Two sensors, two jobs: radar for vehicles and mixed lanes, camera for people on foot. Both work with every Infinity projector that has a trigger input, both ship in 1–2 week turnaround, and both can be ordered in any quantity.
Trucks, forklifts & people
The projector stays dark until something is actually coming.
A motion switch for your projector that knows the difference between a vehicle and a person. It watches one approach, closes one relay for a vehicle and another for a person, and it lives outdoors above a dock door as happily as inside an aisle.
People & pedestrians
Made for the people on foot.
A small bullet camera that watches a walkway or crossing and switches the projector on when a person steps into it. It sees the scene as an image, so the detection zone can be shaped to the walkway, and it keeps working in near-darkness.
*Depends on environment and configuration.
Both do the same job at the end: a relay closes and the projector comes on. They differ in what they see and where they belong.
Either sensor arrives pre-wired to a small controller box. The projector wires into that box, and the controller is the only part that plugs into an outlet.
| Radar Sensor | Camera Sensor | |
|---|---|---|
| Reacts to | A vehicle or a person moving toward it | A person entering the zone you set |
| Tells vehicles from people | Yes, on two separate relays | Tuned for people; can separate people, vehicles, objects* |
| Projectors per sensor | More than one, split across two relays; depends on how close together they sit | More than one when they sit close together |
| Shape the zone on site | No: aim with height (2–9 m) and tilt (0–180°); range is factory-set | Yes: adjustable sensitivity and detection zones* |
| Reach | Floor footprint about 3 × 3.5 m at a 2 m mount, 6.5 × 8.5 m at 9 m | 6–8 m (20–26 ft) |
| Darkness | Needs no light at all | 0.01 lux in color, 0 lux with infrared |
| Dust, fog, smoke | Unaffected | Blocks the view, like any camera |
| Privacy | Records nothing; no lens, no image | Works from a camera image; ask about recording for your site |
| Outdoors | Permanent mount above a dock door: IP65, −30 to +60°C | IP65, −30 to +60°C, with a clear line of sight |
| Wiring | 12–36 V AC/DC, no polarity; two dry-contact relays; ~5 m cable to the controller | Relay output to the projector trigger input |
| Price | $688.88 | $788.88 |
| Turnaround | 1–2 weeks, the same as the projectors | |
| Pick it for | Dock doors, forklift aisles, gates, mixed lanes, anywhere outdoors | Pedestrian crossings, walkways, doorways people use |
*Depends on environment and configuration.
Start from the thing you want the projector to react to. That decides the sensor; the projector is whichever unit you already chose for the space.
| Your situation | Get | Why |
|---|---|---|
| A truck backing to a dock door should switch on a keep-clear zone or a laser line inside | Radar | Rated down to 5 cm/s, so a slow reverse triggers it. Direction-aware, so trucks passing sideways in the yard do not. Mounts permanently outdoors above the door. |
| Forklifts entering an aisle should light a warning on the floor | Radar | Built for approaching vehicles. One direction of approach per sensor; cover both ends of the aisle with two. |
| One opening carries forklifts and people, and each should get its own warning | Radar | Two relay outputs: one closes for a vehicle, the other for a person. One sensor switches two projectors, a laser line for one and a gobo zone for the other. |
| A pedestrian crossing or walkway, tuned to people, with the zone shaped to the walkway | Camera | Image-based detection with adjustable sensitivity and zones, a 3.6 mm or 6 mm lens to fit the walkway width, 6–8 m reach. |
| The sensor has to work in the dark, in dust, fog or smoke | Radar | Radar needs no light and is not blinded by poor visibility. The camera also sees in near-darkness (0.01 lux color, 0 lux with IR), but not through fog or dust. |
| Staff or visitor privacy is a concern | Radar | Radar detects motion only. No lens, no image, nothing recorded. |
| The projector must stay on while a truck sits at the door | Ask us | The radar relay opens about half a second after movement stops, and that is fixed. A timer relay on the output keeps the projection on; we spec it with the order. |
| A large site with several doors or aisles | One sensor per zone | Each sensor watches one direction of approach across one patch of floor. Projectors clustered in a zone can share it; projectors spread out cannot. Send us the layout and we count it with you. |
The sensor is the switch; one of these is the light. Every Infinity projector with a trigger input accepts either sensor, and each product page offers them as add-ons.

A crisp laser line across a dock bay or down an aisle, switched on by the sensor.

Infinity Titan Gobo-Projektor für den Außenbereich mit hoher Wattleistung (150W – 700W)
A high-wattage gobo projector for a large warning zone or sign, indoors or out.

Infinity LY-Pro Compact High-Wattage Outdoor Gobo Projector (135W-200W)
A compact gobo projector for a keep-clear zone, stop sign or crossing pattern on the floor.

The warning appears when a hazard is actually present, so people notice it instead of tuning it out.
Project only when something is coming. A dock that is idle half the day runs the projector half as long.
Less runtime means less wear on the LED and the power supply, and a longer working life.
Both sensors close a dry-contact relay that your electrician lands on the projector's trigger input.
