Why We Invested in Wireless Tally Lights — and What They Do for Business Presenters

If you’ve ever watched a live TV broadcast, you’ll have noticed them. Those small red lights sitting on top of studio cameras, telling the presenter which camera is live at any given moment.

Tally lights.

In broadcast production, they’re standard kit. No serious live TV studio operates without them. We’ve been using them for years across high-stakes environments — from live broadcasts with the BBC to covering auctions on the floor of Sotheby’s in London. In those worlds, they’re expected. They’re part of the infrastructure.

Now we’re bringing that same thinking into the corporate events space.

The Problem with Not Knowing

When a senior leader steps up to deliver a live quarterly results presentation or a company townhall, they’re already managing a significant cognitive load. They’re thinking about their script. Their delivery. Their posture. Eye contact with the room. The pacing of their words.

The last thing they need is a background doubt running alongside all of that: “Is this the right camera?”

It sounds trivial. It isn’t. That kind of low-level uncertainty is exactly what erodes confidence in live performance. The presenter might glance at the wrong lens at the wrong moment. They might hesitate before turning to face the audience, unsure whether the shot has changed. They might ask the director for reassurance mid-count, which disrupts the whole room.

A tally light removes that doubt entirely. The red light comes on, and they know. It’s that simple.

“The moment a presenter understands what the tally light does, their confidence visibly lifts. They stop second-guessing.”

What We’ve Just Invested In

We’ve upgraded to a new set of Hollyland wireless tally lights. Our previous setup had a slight lag and wasn’t always straightforward to configure across multiple cameras, which added friction when we were working fast in a live environment.

The Hollylands are quicker, cleaner, and designed to scale across a larger camera count without complexity. For a multi-camera corporate production — which is the standard format for any serious townhall or results broadcast — that scalability matters.

Why This Changes the Experience in the Room

Beyond the obvious benefit of telling the presenter which camera is live, tally lights allow us to do something that significantly improves the quality of the final output: a clean, silent count-in.

No hand signals from the director. No verbal cues. No disruption to the room’s atmosphere. The director counts the presenter in, the red light fires, and they’re live. It’s professional. It’s seamless. And it mirrors exactly how broadcast television operates.

“The tally light allows us to do a clean silent count-in — no hand signals, no disruption — and the second that red light fires, they’re live.”

What we consistently see when we introduce tally lights to clients who haven’t used them before is a visible shift in presenter confidence. They stop worrying about the technical side of the shot. They can look at the audience, come back to camera, and trust the production around them. That trust shows in their performance, and their performance shows in the final product.

Small Kit. Serious Difference.

There’s a broader principle here that applies across everything we invest in at GLO: the best production technology isn’t the flashiest piece of kit. It’s the piece that removes friction, builds confidence, and protects the quality of what ends up on screen.

Tally lights aren’t glamorous. They’re a small red light on a camera. But they’re one of those pieces of kit that — once you’ve used them — you’d never run a live production without.

“We’ve seen it time and again. The moment a presenter understands what the tally light does, their confidence visibly lifts. They can look at the audience, come back to camera, and trust the shot.”

If you’re planning a live broadcast event — a townhall, a results presentation, a hybrid summit — and you want to know how we approach production quality from the ground up, we’d be glad to talk through what that looks like for your organisation.
