Tech at Alveus

Alveus Sanctuary is a virtual education center, and with that comes the need for a lot of technology to make it all work, from livestream broadcast systems to PTZ cameras and microphones in the ambassador enclosures.

Live Cam Controls

Anyone subscribed to Alveus Sanctuary on Twitch can control the position of the cameras currently shown on the livestream! Use the commands below in the Twitch chat to load preset positions, change the layout of the stream, or even tweak the focus or zoom of the cameras.

!ptzlist [camera:string]: Copy
Get all preset positions for a camera, or get the cameras on stream currently
!ptzload <camera:string> <preset:string>: Copy
Move a camera to a preset position
!ptzhome <camera:string>: Copy
Move a camera to its home position
!ptzzoom <camera:string> <zoom:number>: Copy
Change the relative zoom level of a camera (greater than 100 zooms in, less than 100 zooms out)
!ptzfocus <camera:string> <focus:number>: Copy
Change the relative focus distance of a camera (-9999 to 9999)
!ptzautofocus <camera:string> <mode:'on'|'off'>: Copy
Control auto-focus (if supported)
!swap <camera:string> <camera:string> | <camera:string> <position:number> | <position:number> <position:number> | <position:number> <camera:string>: Copy
Swap the layout of cameras currently on stream

Commands can be run from the AlveusSanctuary Twitch chat, or from the AlveusGG Twitch chat instead to keep the main chat clean. In either case, you need to be a subscriber to the main Alveus Sanctuary Twitch channel to use the commands.

Need help with moving the cameras to a position not covered by presets? Ask the moderators in Twitch chat as they have full access to control the cameras (and edit preset positions for you to use).

Camera Presets

Overwhelmed by the number of camera presets available, or just don't want to run commands by hand in chat? We've got you covered with our camera presets page! View thumbnail previews and descriptions of all the camera presets available, and if you're signed in as a subscriber, you can load them directly from the page to control what views are shown on stream.

Chat Commands

The bot that we use in our Twitch chat to control the cameras has many more commands available! Many of the commands are restricted to moderators only, but some of them are available to subscribers (beyond those documented above) or even everyone in chat.

Open-source

We believe in being transparent in all that we do, and that includes the code we're writing to power Alveus Sanctuary. This website, our Twitch extension, and even that chatbot used to control the cams, are all open-source on GitHub. We're not just building in public, we're also always looking for community contributors to help us improve them!
