Buzzer, lighting and relay
Everything in this chapter belongs to the device: it is attached to this booth and stays unchanged when events are switched.
Buzzer and key control#
For guests a buzzer is the more natural control than a screen — anyone can hit a button. Technically a wired buzzer identifies itself as a keyboard or mouse.
| Setting | Meaning |
|---|---|
| Enable buzzer control | The master switch |
| Assigned key | Via "Capture key" and then pressing the buzzer. The left mouse button cannot be assigned because it is the normal control |
| Behaviour when triggered | Capture immediately or "start countdown" — the latter gives guests time to pose |
| Debounce time | Blocks further triggers so that repeated banging produces only one picture |
| Automatic start after | 0 is off; otherwise the countdown starts by itself after this time |
| Assignment with several buzzers | "Alternating per picture" gives each buzzer one picture in turn; the on-screen hint then names the buzzer whose turn it is |
Buzzers are told apart by key, not by device: two buzzers are two keys, even when they share one USB receiver.
Wireless buzzers over Bluetooth#
A wireless buzzer needs no cable and is identified by its Bluetooth address. That address is fixed in the device, unique worldwide and survives any firmware update.
Setting up: start "Search buzzers" and press the buzzer to be assigned while the search runs — it then shows up as "currently pressed". Registered wireless buzzers appear in the "Buzzer / key control" section, where you set what they trigger.
| Setting | Meaning |
|---|---|
| Warn on low battery | The warning stays until acknowledged |
| Warn on connection loss | Short dropouts are ignored; the message names the likely cause |
| Grace period before reporting loss | How long reconnecting is attempted before the loss is reported |
| Notice when a buzzer falls asleep | Explains to the next guest why the buzzer does not react at first |
| Debounce and wake-up window | Stop a wake-up press from counting as a second capture |
Lighting control#
Controls the connected LED lighting: continuous light during operation and a trigger light at the moment of capture. The trigger light is enabled in the camera area ("Enable LightControl trigger light", photos only).
Relay#
Switches connected devices through a USB relay — a ring light, a flash or a socket that should come on together with the booth.
