Real-time performer tracking

The system that follows
the performer.

Automated tracking for live entertainment. Your lights, cameras, sound, and safety systems lock onto every performer and follow them in real time, hands-free.

Works in blackout and haze. Drops into the rig you already own. A fraction of the cost of every other system.
Professional performer tracking, thousands of dollars cheaper than anything else on the market.
The capability of systems that cost as much as a car, built from modern radio and delivered by people who run shows.
How it works

Three pieces. That is the whole system.

No cameras, no calibration nightmares, no specialist operator. Small radio units find your performers to the centimeter and tell your gear where to point.

01

Tag the performers

Each performer wears a small, light, battery-powered tag. That is all they carry, and it works through costumes and in-ears.

02

Ring the stage with anchors

A handful of radio anchors mount overhead around the stage. They measure exactly where each tag is, 20 times a second.

03

Everything follows

Positions stream to your console in the standard protocol it already speaks. Bind a fixture to a performer and the beam tracks them, live.

One system, four jobs

If it can aim at a point, Sightline can drive it.

Because the tracking speaks the open industry standard, the same rig follows performers with lights, cameras, sound, and safety, no new hardware.

Lights

Moving heads, spots, and beams lock onto each performer automatically. Replace the follow-spot op.

Cameras

Robotic and PTZ cameras keep a moving performer perfectly framed for IMAG and streaming.

Audio

Immersive and object-based sound pans a voice through the room as the performer moves.

Safety

Pyro and effects hold their cue when a tracked person is in the hazard zone. People first.

Why Sightline

Everything the expensive systems do. None of the reasons not to.

A fraction of the cost

The capability of systems priced for arena tours, at a small fraction of the price. Thousands of dollars cheaper than anything comparable.

No operator required

It runs itself. Bind performers to fixtures once and the show follows. Or we operate it for you.

Works in any lighting

It is radio, not a camera. Blackout, haze, strobes, full wash, it never loses the performer.

Drops into your rig

Speaks PosiStageNet, the protocol modern consoles and media servers already understand. No rip-and-replace.

Set up in minutes

Ring the stage, walk a calibration path, done. No survey crew, no week of commissioning.

Runs fully offline

No internet, no cloud, no latency. Everything happens on the floor, in real time, every time.

Built to be dead simple

Calibrate in minutes. Walk the stage. Done.

  • One dashboard, any browser. Watch performers move, check battery, see everything at a glance.
  • Guided calibration. The system walks you through it and saves a preset per venue.
  • One-touch kill switch. Freeze all tracking instantly if a cue ever looks wrong.
  • Hot-swap tags. A performer swaps to a spare in seconds, mid-show, no downtime.
Made for live entertainment

Wherever a light needs to find a person.

From a club stage to a cathedral to a broadcast set, Sightline scales to the room and the show.

Questions, answered

Everything you are probably wondering.

How does it actually track people?

Ultra-wideband radio, the same precise-location tech in a modern phone. Anchors around the stage measure the exact distance to a tag worn by each performer, and the system computes their position in 3D to roughly 15 centimeters, 20 times a second.

Does it work in blackout, haze, or heavy lighting?

Yes. It is radio, not a camera, so it does not care about light at all. Blackout, haze, strobes, lasers, a blinding wash, it tracks exactly the same in every one.

What can it control?

Anything that can aim at a point and reads PosiStageNet or OSC: moving lights, follow spots, robotic and PTZ cameras, immersive audio systems, and effects interlocks. One rig, all of them.

What consoles and gear does it work with?

It outputs PosiStageNet v2, the industry-standard tracking protocol. GrandMA2 and MA3 both take it, along with many other consoles and media servers. It drops into a rig you already own.

How many performers can it follow at once?

As many as you have tags. Every performer with a tag becomes a tracked target you can assign to any fixture. It scales from a soloist to a full band and beyond.

Do I need a special operator?

No. You bind each performer to their fixtures once, and the show follows automatically. If you would rather not touch it at all, we can set it up and operate it for you.

How long does setup take?

Minutes, not days. Ring the stage with anchors, walk a short calibration path, and save the venue preset. Next time you are at that room, you recall it and go.

Does it need internet?

Never at showtime. Everything runs locally on the floor with no cloud and no latency. A venue with zero internet runs perfectly.

What do performers have to wear?

A single small, light, battery-powered tag, pocket-sized. It works through costumes and alongside in-ear packs, and the battery lasts a full show with hot-swap spares on hand.

What about safety around pyro and effects?

Our safety layer knows where every tracked person is and will hold a hazardous cue if someone is inside a danger zone. It is defense in depth on top of your existing safety practice, not a replacement for it.

How much cheaper is it, really?

Dramatically. It delivers what systems costing as much as a car do, for a small fraction of the price, thousands of dollars cheaper than anything comparable on the market, with no operator to hire either.

Can it follow cameras for streaming and IMAG?

Yes. The same position stream drives robotic and PTZ cameras to keep a moving performer framed automatically, which is a game changer for worship, corporate, and broadcast.
