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.
Radars and cameras spot forklifts, robots and people, and the projected lines and signs switch on cue. Open any scene live, then change it to match your building.
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.
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.
