Safety Sign & Warehouse Projection Solutions

A safety sign projector is an overhead LED projector that casts a bright safety marking — a walkway, hazard zone, stop line, arrow or custom sign — onto the floor or a wall. Unlike paint or printed signs, the projected marking never wears off and can be changed in seconds.

Yes. Our Warehouse Safety Planner, a free laser line planner at infinityprojectors.com/preview-pilot/laser-planner, runs in your browser. Draw laser lines, crosswalks, keep-clear zones and projected signs to scale on a sample warehouse, your own floor photo or a floor plan. It counts the projectors each run needs, adds radar and camera sensors, and lists every part with a budget price. Final specs and pricing follow a site review.

Yes. The Warehouse Safety Planner has a live 3D view: forklifts, robots, trucks and people move through your layout, the radar or camera sensors trigger, and the projected STOP, GO and warning signs switch on cue, with a caption explaining each change. Start from a ready-made scene, like a forklift crossing or a dock door, and change it to match your floor.

A complete projected safety system from one supplier: laser line projectors for aisle edges, walkways and keep-clear zones; gobo floor sign projectors for STOP, crosswalk, forklift caution and arrow signs; radar and camera sensors that switch them on when traffic comes; and the free Warehouse Safety Planner to lay it all out and see it working in 3D before you buy.

Laser line projectors mount from about 3 ft up to 20 ft (10W) or 33 ft (20W, 30W and 40W), and each line is about the mounting height times the lens ratio. Floor sign projectors size the sign by height too: the sign is about the lens number times the height across, so a 0.33 lens 20 ft up makes a sign about 6.6 ft wide. Higher mounts need more wattage. Mount every unit in a run at the same height, on solid building steel or racking.

Yes, when they are sized for the light. A thin laser line looks brighter than a wide one, green is the easiest laser color to see, and a higher wattage holds up better on a brightly lit floor. For floor signs, a lit warehouse calls for the top of the wattage range for your mounting height. The planner and the Wattage Finder size both for your room light, and we confirm it after a site review.

Choose 1:1.2 for premium quality: each unit draws a line about 1.2 times its mounting height, and it is the crispest, most evenly bright line. Choose 1:4 to stay within budget: each unit draws up to 4 times its height, so you need fewer units, but the ends look softer. 1:2 and 1:3 sit in between. The ratio is set when the projector is built, so choose it before you order.

Divide the run by the line one unit draws and round up. A 120 ft aisle with units 20 ft up needs two units at 1:4 (about 80 ft each) or five at 1:1.2 (about 24 ft each). On long 1:4 runs, plan an extra unit so the dimmer ends can overlap and the joined line looks even; with 1:1.2 the line stays solid end to end.

Yes. Laser lines mark the lane edges, a projected crosswalk or STOP sign marks the crossing, and a sensor switches the warning when traffic approaches. For robots (AMRs and AGVs), the best trigger is your robot system's own signal if it can send one; otherwise a radar sensor. The planner has ready-made crossing and robot scenes you can watch in 3D.

A radar or camera sensor is wired to a small controller, and the projectors wire into the controller. The radar reacts to movement toward it, from a slow creep up to about 15 mph, ignores traffic crossing sideways, and has separate relays for vehicles and people. The camera sensor is the more sensitive choice for people on foot. One controller runs two or three projectors that switch together, and each radar watches one direction of approach.

Projected markings are widely used to support OSHA-style safety programs — marking walkways, forklift zones, hazard areas and PPE requirements. They supplement and often improve on painted markings because they stay bright and crisp. Always confirm the specific requirements for your facility and jurisdiction.

Use a gobo sign projector when you need a custom image, symbol, text or logo, or want to change the message. Use a laser line projector when you need an ultra-bright, perfectly straight boundary line for a long walkway or zone. Many facilities use both together.

Yes — with the right wattage. Brightness depends on ceiling height, image size and ambient light. High-wattage and laser line units stay clearly visible in bright, high-ceiling and daylight environments. Our team (or the Wattage Finder) sizes the right unit for your space.

Much more durable. There's nothing on the floor to scuff, peel, fade or get dirty. The projector's LED runs for tens of thousands of hours, and the marking stays sharp and bright the entire time — eliminating the repaint cycle.

Yes. Multi-lens projectors can rotate through several signs from one unit, and any gobo sign can be swapped in seconds. As your layout or operations change, the markings change with them — no repainting.

They mount overhead — to ceilings, beams, racking, track or embedded fixtures — and plug into a standard outlet. No special wiring or install crews are required. Mounting height and angle are set to your space.

Yes. We create custom gobos for any safety sign, symbol, arrow, text or logo your facility needs — and every order includes 2 FREE custom gobos with design help to get them perfectly clear and bright.

Mounting height sets the image size: the sign's width is the lens number times the height — with a 0.33 lens, a projector 20 feet up makes a marking about 6.6 feet across. Brightness has to match the height too: in a well-lit warehouse, plan on roughly 100–120W at 16 feet, 120–150W at 20 feet, and 200–300W around 26 feet so markings stay vivid instead of washed out. Give us your ceiling height and ambient light and we'll spec the exact unit.

No — a projected sign is light, so it goes dark in an outage like any other fixture. That's why projection is best used to supplement, not replace, code-required physical signage: emergency exits and egress paths still need their physical illuminated signs. Where projection shines is the day-to-day layer — aisle markings, forklift zones, and reminders that never fade, peel, or get scrubbed off by traffic.

Yes — that's the superpower. Re-aim the projector or relocate the mount, and the marking moves with it: no grinding off old paint, no peeling up worn tape. If a re-slot changes what the sign needs to say, you swap the gobo disc in seconds. For facilities that reconfigure often, that flexibility is usually the deciding factor over painted lines.

About 17 cents per fixture per 10-hour shift — a 100W projector uses roughly 1 kilowatt-hour over that time, around $5 a month per sign at typical US electricity rates (~$0.17/kWh). Compare that with repainting floor lines or replacing scuffed physical signage and the economics explain themselves: facilities just leave the signs lit every working shift.

Yes. Our programmable timer add-on ($88.88) switches a whole circuit of projectors on and off to match your shifts, with programs set by day (weekdays only, for example), so markings are lit whenever crews are on the floor. Laser lines and our 300W and LY gobo projectors come back on in the mode you left them. One timer runs about 20 laser lines at 40W, or about 2 gobo projectors at 300W, on 110V; an electrician wires it in on a DIN rail, and changing the schedule afterwards is just a few button presses.

It depends on what you're detecting. The Radar Sensor ($688.88) is built for approaching forklifts and vehicles — stable detection that keeps working in darkness, smoke, dust, fog and bad weather, and it doesn't capture images, which makes it the privacy-friendly pick for general safety zones and entry areas. The Camera Sensor ($788.88) is built for people — better pedestrian-detection performance, day/night operation with IR illumination, and it can distinguish between people, vehicles and objects with adjustable sensitivity and detection zones* (*depends on environment and configuration). Forklift lanes and dock doors lean radar; crosswalks and walkway zones lean camera.

Yes — that's the recommended setup for mixed-traffic aisles where forklifts and foot traffic share the same space. The Radar Sensor handles vehicle detection and the Camera Sensor handles pedestrian detection, wired independently into the same projector or warning system so both trigger types are covered.

Often, yes. Size coverage by zone, not by projector — a long aisle or a facility with multiple dock doors typically needs a sensor per zone so each approach path gets its own detection. Sensors can be ordered in whatever quantity your layout needs.
