“11 guests” means up to 11 additional guests or camera angles, according to Streamlabs’ Collab Cam product page; it does not mean 11 guests in total. Streamlabs describes one guest as available free in Desktop and associates the additional capacity with Ultra.
To invite people in Streamlabs Desktop, add a Collab Cam source, start it, send the generated link, review each join, then select Show on Stream when that feed is ready for viewers. The invitation and review steps are straightforward; the part worth testing in advance is how the guest audio and multiple feeds appear in your scene.
What “11 guests” means
The count is easy to misread. Streamlabs’ product page says Desktop Collab Cam includes one guest free and that Ultra supports “up to 11 additional guests or camera angles”. A separate Streamlabs article describes Ultra users having all 12 Collab Cam slots. Read those descriptions together, but avoid treating “11” as 11 total people or assuming how the application labels the host and each slot.
The word “additional” is important: the product page is describing capacity beyond the free single-guest arrangement. It also groups guests and camera angles, so the capacity can be used for remote people, extra device feeds, or a mix, subject to what the current app lets you add. A phone pointed at a drawing table, for example, can provide a different view from the remote speaker’s webcam; it is not a way to unlock Ultra capacity.
| Desktop configuration | What Streamlabs documents | What it means for your setup |
|---|---|---|
| Free Collab Cam | One guest | Suitable for a conversation with one remote participant. |
| Ultra Collab Cam | Up to 11 additional guests or camera angles | The documented option when you need more than the free single guest. |
These are Streamlabs plan-capacity statements, not a promise that every computer, connection, or scene will handle every feed smoothly. The cited product material does not publish a tested layout for a full group of 11 additional feeds. If the count matters for a planned event, check the current Ultra and in-app information before buying or inviting everyone.
Check the Ultra requirement
If your session needs more than one guest, check the plan requirement before building the show around Collab Cam. Streamlabs ties the advertised capacity of up to 11 additional guests or camera angles to Ultra. The free Desktop arrangement is one guest, so do not plan a free setup around the larger capacity.
The core Desktop workflow remains the same: add the source, start Collab Cam, share the link and choose which joined feed to put on stream. A plan changes the stated capacity, not the basic invitation sequence. Check the current Streamlabs Collab Cam page for its current description of availability and plan terms; plan details can change, so use the page rather than an old screenshot or a remembered price.
It is also worth distinguishing Desktop Collab Cam from Streamlabs Talk Studio. They are separate products and their guest limits or controls should not be transferred from one to the other. This guide covers Collab Cam in Streamlabs Desktop. Streamlabs also documents Collab Cam on mobile, but the scene and guest-layer workflow differs; see the official mobile guide if you are hosting from a phone.
Before you commit to a large group, decide what each feed is for. An interview may need one guest at a time on screen even if more people are waiting to join. A panel may need several visible faces. A tutorial could use one remote guest plus a close-up camera angle. Thinking through the intended scene first makes it easier to test whether the capacity solves your actual production need.
Add a Collab Cam source
Open Streamlabs Desktop and go to the scene where you want the guests to appear. In Sources, click the plus sign, select Collab Cam, and add the source. Streamlabs’ Desktop Collab Cam instructions cover the source setup and invite workflow.
A source belongs to a scene, so add it to the scene you intend to use rather than assuming it will appear in every scene. If your programme has a waiting scene and a main discussion scene, consider where the Collab Cam source should be available and how you will move between layouts. Make those choices before guests arrive, when you can inspect the scene without rushing.
After adding the source, open its controls. The source is the starting point for the session, but adding it alone does not put a guest on the broadcast. You still need to start Collab Cam, send a join link, and explicitly show a guest when you are ready. Keeping those steps separate gives you a chance to check the feed before your viewers see it.
The source’s placement and size also matter. If you are bringing in several people, decide whether you want a panel grid, a larger active speaker, or a single guest at a time. Streamlabs’ cited instructions establish the guest and camera-angle capacity, but do not prescribe a tested arrangement for 11 additional feeds. Build a practical layout for your own scene and test it with the devices and people you will actually use.
A guest feed is not the same thing as a separate scene design. If you rely on titles, a host camera, or other overlays, check that the new source does not cover them. Keep a simple fallback scene available in case a guest’s camera is unavailable or you need to take the panel off screen while fixing audio.
Start Collab Cam and share its link
Select the Collab Cam source and choose Start Collab Cam. Streamlabs generates an invitation link. Copy it and send it privately to the intended guests, using a direct message or email rather than placing it in a public chat or on a public page.
Guests use the link to join from a browser. Send a short note with the link explaining when to join and whether they should check their camera and microphone first. For an organised panel, invite participants in a sensible order and ask them to wait for your cue before speaking. This is not a technical requirement, but it can make it easier to identify each feed and check the scene without several people talking over one another.
Treat the link as access to the guest flow. Streamlabs advises sharing it only with people you know and trust. If it may have been forwarded or exposed, generate a new link and distribute the replacement directly to the intended guests. Do not assume that an old link is private once it has escaped the group.
If you are already live, avoid sharing your screen during setup if that could reveal the invitation or other private information. Prepare the scene and the guest workflow before going live where possible. Streamlabs’ Desktop guide includes these safety points and also reminds guests to follow the rules of the streaming platform. A private invitation does not remove your responsibility to moderate what goes out on your channel.
The link is not a reason to let an unfamiliar person straight onto the broadcast. Use the review step before showing anyone. For a public-facing programme, agree in advance who is responsible for checking the waiting guests and who can remove a feed if something unexpected happens.
Review the guest or camera angle
Let a guest join, then check the feed in Collab Cam before you put it in front of viewers. Confirm that the person or device is the one you expected, that the image is usable, and that the guest understands when they are live. A spare phone, tablet, or laptop can act as another camera angle, but it is optional; no particular physical camera is required to invite remote guests or obtain the Ultra capacity.
Do not treat a visible camera preview as proof that the audience will hear the guest. Streamlabs notes that the host may hear a guest even when viewers do not. If the guest audio is missing from the programme, its guide suggests adding an extra microphone source. Check the actual audience-facing mix before the discussion begins, rather than relying only on what you hear locally.
A useful rehearsal is to have one person join and speak while another checks the stream output or recording from the viewer side. Listen for the guest, the host, and any overlap or echo. If you adjust audio routing or add a microphone source, test it again. The exact controls depend on your setup, so use the current Desktop guide and inspect the audio sources in your own scene instead of assuming that a local monitor reflects the broadcast mix.
For a larger group, test the scene with the expected number of feeds before the event. Check whether faces are legible at the sizes you have chosen, whether names or other overlays remain visible, and whether your host can keep track of who is speaking. Streamlabs’ cited material does not give a recommended computer specification, bandwidth figure, or tested full-group layout. Do not treat the advertised guest capacity as a performance guarantee for your particular setup.
For an always-on channel, this is a different production problem from keeping a recorded programme running overnight. If your channel uses both formats, the guide to running a continuous YouTube stream from a Synology NAS discusses a separate recorded-stream workflow. For a live panel, your priority is a supervised guest and audio check before you reveal a feed.
Click Show on Stream when ready
Once you have reviewed the guest, select Show on Stream for that feed. Until you do this, a guest’s successful join does not by itself mean the audience can see them. This gives you a deliberate review point: you can confirm the right person has joined and that their video is appropriate before making it part of the programme.
Repeat the review for each additional guest or angle you want to show. Arrange and size the feeds to suit the scene, then watch the programme as a viewer would. If a feed is not visible, check that you have selected Show on Stream rather than assuming the join failed. If it is visible but silent, return to the audience-side audio check rather than asking the guest to repeatedly reconnect.
For a panel, agree a simple speaking order and a way to signal when someone is ready. Collab Cam provides the guest connection; it does not decide how you moderate a conversation or make a crowded layout clear. If the event is an interview, you may prefer to show one guest at a time. If it is a discussion, you may choose to keep several faces visible while making the active speaker clear through your scene design.
If you are planning to bring guests into a continuous channel, consider how the live segment fits the wider schedule. The recorded-sermon channel guide addresses a different use case, but can help distinguish a scheduled live contribution from a stream that simply loops recorded material. Keep the guest session and its moderation needs explicit rather than assuming an unattended loop can manage a live conversation.
Make a rehearsal part of the setup
A short rehearsal catches problems that the guest count alone cannot reveal. Invite a test participant, check the link opens in their browser, review their picture, show the feed, and confirm that the audience hears both sides. Run the same steps with any phone or secondary camera you intend to use. If the event includes multiple guests, practise the hand-off and the layout changes you plan to make.
Test on the scene and equipment you will use for the event. A layout that is easy to inspect while you are setting it up may be harder to manage when you are also hosting. Keep controls for the host and overlays accessible, and have a way to remove a feed from the programme if its video or audio becomes unsuitable. The point is not to predict every failure but to know which control you will use when one occurs.
If you stream other formats from the same machine, separate the requirements. The guide to making a YouTube gaming replay survive an internet outage covers resilience for a replay channel, not Collab Cam guest handling. For a live group, the practical safeguard is to test the join, show, and audio path and to keep the invitation private.

FAQ
Does “11 guests” mean 11 people including the host?
Streamlabs’ product page describes Ultra as supporting up to 11 additional guests or camera angles, while another Streamlabs article refers to all 12 slots. Do not describe the product-page figure as 11 total; check the current in-app count if you need to know exactly how the host is represented.
Is the 11-additional capacity free?
No. Streamlabs describes one guest as available free with Desktop Collab Cam and associates up to 11 additional guests or camera angles with Ultra. Check Streamlabs’ current product information for the terms that apply when you set up your stream.
Why can I hear a guest when viewers cannot?
Local monitoring and the audience-facing mix are not necessarily the same. Streamlabs notes this can happen and suggests adding an extra microphone source; test the output as a viewer before the conversation begins.
Can I use a phone as a Collab Cam angle?
Streamlabs documents mobile Collab Cam and describes a phone as an optional extra camera angle. The mobile steps differ from Desktop, so use the official guide for your device rather than assuming the buttons match.
