A spare phone can act as a second camera in Streamlabs Desktop through Collab Cam: add the source on your computer, create an invite link, then open it on the phone and choose a camera to share. Before putting that view on stream, check that the picture is framed as intended and that any sound you need is reaching the audience mix.
The phone joins through a browser, so its camera, internet connection and browser access need to work together; do not assume every device or browser will behave the same way. This guide covers the desktop workflow, a safe way to handle the invite, and the different scene-and-layer approach in Streamlabs Mobile.
Check the primary camera and microphone
Start in Streamlabs Desktop with the account or streaming platform you intend to use connected. Check the existing scene before adding another camera: confirm that your main camera is visible, its framing is right, and the microphone you expect to use is active. This gives you a known-good baseline. If a problem appears after adding Collab Cam, you can tell whether it belongs to the new feed or was already present.
Look at the scene preview rather than relying only on the camera indicator. Confirm that the picture is not hidden behind another source, cropped unexpectedly, or covering information you need to keep visible. Speak at your usual distance from the microphone and check the audio meter. If you are preparing a long programme, a short test recording can help you review the picture and sound without exposing setup mistakes to viewers.
Decide what the second angle is meant to show. An overhead phone view might show hands arranging devotional instruments, a cooking surface, or a workbench; a side view could show a keyboard or a person speaking. A second camera is most useful when it reveals a detail the primary camera cannot. If both views show nearly the same framing, the extra source may add setup and audio complexity without helping the viewer.
If you are new to the application, our Streamlabs and OBS comparison can help you orient yourself to the different workflows. The steps here assume Streamlabs Desktop is already open and that you can edit its scene. They are not a general guide to setting up a YouTube broadcast from scratch.
Add a Collab Cam source
In Streamlabs Desktop, find the Sources panel for the scene you plan to use. Select its plus button and choose Collab Cam from the available source types. The precise appearance or wording of interface controls can change, so if your menu differs, consult the current Streamlabs Desktop Collab Cam guide rather than guessing at a similarly named source.
Once the source is added, select or open it and start Collab Cam. The host side of the workflow creates an invite link for the other device to join. Keep the source in the scene where you want the additional view to be available; you can prepare its size and position before showing it to viewers. Source visibility and audience visibility are not the same decision: leave yourself time to inspect the incoming feed before using the Show on Stream control.
The desktop source workflow differs from bringing in a local webcam: the phone connects to the collaboration session using the link, while Desktop receives the resulting camera feed. Streamlabs describes Collab Cam as a way to bring additional camera angles into a stream. Its Collab Cam page is the primary product reference for current availability and feature descriptions.
Do not start by distributing the link broadly. First create it, then send it only to the device or person that should join. The phone owner may need to grant camera access in the browser, and a prompt can appear on the phone rather than on your computer. If the browser does not ask for permission or the feed does not arrive, check the device’s browser permissions and network access before removing and recreating sources at random.
Start Collab Cam and create an invite link
After starting Collab Cam, use the link provided by the source for the spare phone. Depending on the current interface, the link may be copied or otherwise made available from the source controls. Check the current on-screen instruction if you do not see the same labels shown in a tutorial. A link generated for this session is access to the collaboration; treat it as a private invitation, not as a public page to post in chat or on social media.
Send the link through a channel available only to the intended participant, or open it directly on the phone if you are handling both devices. Take care when copying and pasting: make sure you have the complete link, and avoid including it in a public stream title, description, on-screen overlay, or message. If you are streaming while configuring the source, remember that sharing your desktop can reveal setup information. Streamlabs cautions against sharing your screen during Collab Cam setup on an active stream.
The link is a joining route, not proof that the phone has connected. The phone still has to open it, grant the requested camera permission, select a camera, and complete the join step. Keep Desktop visible while doing this so you can see whether a participant or feed appears. If the invite does not work, verify you are opening the latest link and that you have not replaced it with a newly generated one.
If you are deciding whether your whole programme should be a live camera production or a prepared video loop, those are separate workflows. For a continuous pre-recorded channel, our guide to running a 24/7 recorded-sermon stream covers a different use case. Collab Cam is for an additional live camera angle in a Streamlabs production, not a way to turn a phone into an always-on prerecorded channel.
Open the link on the spare device
On the spare phone or tablet, open the invite in a browser. Streamlabs’ iPhone and iPad secondary-camera tutorial describes opening the link in a browser and choosing a camera to share. The guide is specific to Apple devices; it should not be read as a promise that every phone, operating system or browser combination is supported. Use a device with a working camera and internet access, and be ready to check browser permissions if the join page cannot use the camera.
If you receive the link on the phone, open it from the message intended for you and check that it leads to the expected Collab Cam join page. If you are moving the link between devices, take care not to paste it into a public chat or a shared document. When the page asks for access to the camera, allow it only if you are happy for that camera view to be sent into the session. A permission prompt may be controlled by the browser or the device’s privacy settings.
A blank preview does not always mean the source in Desktop is broken. The phone may have denied permission, another app may be occupying the camera, or the browser may not have completed the join. Check that the phone is online, that the page is still open, and that camera access is enabled for that browser. You can also try another browser available on the device, but treat that as a troubleshooting step rather than assuming all browsers are interchangeable.
A spare device should be positioned before you judge the feed. A stable surface or an optional phone mount can help hold an overhead or side angle, but no particular accessory is required by the Collab Cam workflow. Check that the camera does not point at private information, a doorway, or an area that should remain off camera. For a long session, consider how the device will remain powered and whether the subject is lit well enough to be seen; these are practical production checks, not feature requirements.
Choose and share the camera
When the join page offers camera choices, select the lens that gives the framing you want. Phones with more than one camera may offer different fields of view; the available choices depend on the device and browser. Check the preview before proceeding. If it shows the wrong direction or an unintended part of the room, change the camera selection or physically reposition the phone before you share it.
Complete the join or sharing action on the phone, then return to Streamlabs Desktop. Wait for the incoming feed to appear in the Collab Cam source. Do not assume that a successful permission prompt means the camera is already visible to viewers. First confirm that the source is receiving an image; then adjust its position and size in the scene so the second angle supports rather than obscures the main picture.
For an overhead view, place the phone so the camera can see the work area without the mount or your hands blocking the subject. For a musical instrument, a slight side angle may communicate playing technique better than a top-down view. For a product demonstration, keep enough space around the object that viewers can follow movement. These choices depend on the content; there is no single scene layout that suits a bhajan performance, a local-news desk and a study stream equally well.
When the image is ready, use Show on Stream to make it part of the programme. Before doing so, inspect the scene preview and confirm that the new source is not covering captions, a logo, or essential text. Keep a way to hide the source if the phone is moved, disconnected, or pointed somewhere unintended. A second camera adds flexibility, but it also introduces another live view that someone needs to monitor.
Review the feed and audio
Check the incoming picture at the size viewers will see it. A small thumbnail can hide focus, exposure or framing problems. Look for motion blur, reflections, distracting background details and whether the intended subject remains within the frame. If the phone is on a table or mount, gently test whether normal movement will shake it. Make adjustments before you rely on the angle during a live segment.
Audio deserves its own check. Do not assume that sound from the phone’s camera will automatically reach the audience in the way you expect. Streamlabs’ Desktop guide notes that the host may hear a guest while the audience does not; if that happens, it suggests adding an extra microphone source. The guide does not provide a universal routing fix for every setup, so verify the actual mix rather than treating the suggestion as a guarantee.
Make a short private test recording or another safe pre-live check. Speak near the phone, then listen to the result through the recording or monitoring path you intend to use. Also check the primary microphone and any other active sources. If the phone’s sound is unnecessary, decide whether to mute or exclude it to avoid room noise, echo or two microphones capturing the same voice with a delay. If its sound is important, confirm that the audience recording includes it at a useful level.
The safest check is one that reflects the final scene and the intended audience mix. Hearing sound in your own headphones is not enough: the audience output may be different. Similarly, seeing the feed in a source preview does not tell you whether the source is actually visible in the scene. Check both the complete programme picture and the recorded or monitored audio before the live session.
If the programme also includes a looped visual or music bed, keep the second camera’s purpose clear. Our article on adding a visualiser to a 24/7 jazz stream discusses a different visual layer, but the same practical question applies: what should a viewer be looking at at this moment? A camera angle should add useful context, not compete with every other element on screen.
Keep the invite link private
Treat the invite link as access to your Collab Cam session. Share it only with the person or device you want to join, and do not place it in public posts, live chat, or a visible screen capture. A link that has been forwarded beyond the intended participant can let someone else attempt to join. That risk is a reason to handle the link carefully, not a reason to assume that every link is public or inherently unsafe.
If you think the link has been exposed, generate a new one from the Collab Cam controls and use the replacement. Streamlabs’ Desktop guide says that generating a new link invalidates the previous link. Tell the intended phone user to use the replacement, and check Desktop to make sure the expected device is the one connected. Do not continue using a link you suspect has travelled further than intended.
During setup, be cautious with screen sharing or desktop capture while the link is visible. If your stream is already live, avoid putting private setup material on screen; pause or hide the relevant capture before handling the invitation. After the session, close the join page on the phone and stop or remove the source as appropriate to your scene. This reduces the chance of leaving an unintended active view in a later broadcast.
Collab Cam is for a live camera contribution, so it is a different tool from an unattended video loop. If the specific problem is keeping a recorded programme running when your own computer is off, that is where StreamNeo removes the need to keep a desktop session running: you upload a video, connect your YouTube stream key, and the broadcast runs as a separate continuous-video workflow. It is YouTube-only and is not a substitute for Collab Cam when you need a phone’s live camera in Streamlabs Desktop.
Desktop and Mobile use different workflows
In Streamlabs Desktop, you add Collab Cam from the Sources panel and use a browser invitation for the remote phone or participant. You then arrange the incoming source in the desktop scene and decide when to show it. This is the workflow described above, and it is the useful route when your production is being assembled in Streamlabs Desktop.
Streamlabs Mobile handles Collab Cam differently. Its guide describes adding a camera or guest as a layer within a scene, adjusting that layer’s size and position, and copying or generating the guest invitation from the layer settings. Consult the current Streamlabs Mobile Collab Cam guide for the app’s current controls. The key distinction is where you create and arrange the source: Desktop uses a Sources-panel source, while Mobile uses scene layers in the app.
Do not follow a Mobile tutorial step by step while expecting to see the same panels in Desktop. If you are switching between products, first identify which device is the host and where the scene is being built. The phone that supplies the extra camera is not necessarily the same device that hosts the stream. That distinction helps avoid looking for an invite-link control in the wrong interface.
Streamlabs’ official materials have also described different guest capacities for paid access at different times or on different pages. The product page and support guide cited above do not agree on the Ultra maximum. Because plan descriptions can change and conflict, check the current product page or in-app limit before planning a production around multiple simultaneous angles. This guide’s second-camera steps do not depend on quoting a capacity figure.
When you are ready to proceed, keep the test simple: use one phone, one intended angle, and one clearly chosen audio path. Add more complexity only after the picture and audience mix are working. If the feed fails, isolate the stage that failed—link opening, camera permission, incoming source, scene visibility or audio routing—rather than rebuilding the whole scene at once.

FAQ
How do I use my phone as a second camera with Streamlabs Collab Cam?
Add a Collab Cam source in Streamlabs Desktop and start it to create an invite link. Open that link in a browser on the phone, allow camera access, choose the camera and join; then check and arrange the incoming feed before showing it on stream.
Does the phone need a special app?
The documented phone workflow uses a browser to open the invite and share a camera, rather than requiring a dedicated camera app. You still need a device and browser that can access the camera and internet, and compatibility should be checked on the device you plan to use.
Why can I hear the phone but the audience cannot?
Monitoring what you hear locally does not prove that the sound is included in the audience mix. Make a safe test recording and check the result; Streamlabs’ Desktop guide notes that an extra microphone source may be needed, but it does not give one universal routing fix.
What should I do if the invite link may have leaked?
Generate a new link in the Collab Cam controls and send the replacement only to the intended participant. Streamlabs says the new link invalidates the previous one, so ask the phone user to open the latest invitation.
