Adding a Camera Source in OBS

The short answer

In OBS Studio, you add a camera with a Video Capture Device source. Open a scene, click the plus button in the Sources panel, choose Video Capture Device, name it, and select your camera from the Device list. A DSLR or mirrorless camera shows up in that list only after its signal has been turned into a webcam-style device. That happens either through an HDMI capture device or through the camera maker's webcam software. Audio is a separate decision. Depending on the route, the camera source may carry the camera's microphone, a webcam's built-in microphone, or no audio at all. Before you go live, decide which microphone OBS should actually use for your voice.

Adding the camera source step by step

• 1. Connect the camera and close other apps that might be using it, such as a video-call client. Many systems let only one program use a camera at a time.
• 2. In OBS, select the scene where the camera should appear.
• 3. In the Sources panel, click the plus button and choose Video Capture Device.
• 4. Choose Create new, give the source a clear name (for example, the camera model), and confirm.
• 5. In the properties window, pick your camera from the Device drop-down. A preview should appear.
• 6. Adjust resolution and frame rate settings if the default image is wrong, then click OK.
• 7. Resize or position the camera in the preview canvas as needed.

If the device list is empty or the preview stays black, the usual causes are another application holding the camera, missing operating-system camera permission for OBS (common on macOS), or a DSLR that is not yet presenting itself as a video device.

How a DSLR or mirrorless camera reaches OBS

OBS cannot talk to most stills cameras directly. The camera's output first has to appear on the computer as a video device. There are two common routes, and the choice affects both image handling and audio.

Route | How it works | Audio implications

HDMI capture device | The camera sends a clean HDMI signal (no on-screen overlays) to a capture card or USB capture dongle. The computer sees the capture device as a webcam. | HDMI can carry embedded audio from the camera's microphone or mic input. OBS may expose that audio through the Video Capture Device source.

Manufacturer webcam software | Several camera makers, including Canon, Nikon, Sony and Fujifilm, have offered utilities that present a supported camera as a webcam over USB. | These utilities are generally described as video-focused. Do not assume they pass camera audio. Check the documentation for your camera and plan on a separate microphone source.

Camera support, settings menus and software features vary by model and firmware. No model-specific evidence was supplied for this guide. Confirm compatibility, clean-HDMI support, and whether the camera has continuous-power or overheating limits using the manufacturer's own documentation.

What this means for capturing your voice

A camera source can bring audio into OBS without you noticing, so check what is being recorded.

• Built-in webcam microphones usually appear as a separate audio input device, not inside the video source. Add them with an Audio Input Capture source, or select them as a global Mic/Auxiliary device in Settings > Audio.
• On Windows, the Video Capture Device properties include audio options, such as using a custom audio device and an audio output mode. These control whether the device's audio is captured and how.
• If the camera audio and a separate microphone are both active, your voice may be recorded twice, which can sound hollow or echoey. Mute or disable whichever one you are not using in the Audio Mixer.
• An on-camera microphone sits wherever the camera is. That is often farther from your mouth than a dedicated microphone, so it picks up more room sound. This follows from basic acoustics; it is not a measured result for any specific camera.

Keeping audio and video in sync

Capture devices and camera processing can delay the video. A separate microphone, meanwhile, may reach OBS sooner. If your lips and voice drift apart, open Advanced Audio Properties from the Audio Mixer and set a sync offset on the microphone source to delay it until it matches the picture. The right value depends on your hardware. Find it by testing a recording, for example a clap on camera, rather than using a fixed number.

Gaps in the available evidence

No specific measurements, latency figures, supported-model lists or audio-quality comparisons were available for this guide. The steps above reflect how OBS Studio sources generally work. Menu names can shift between OBS versions and operating systems, and camera behavior depends on the manufacturer and model. For any particular camera or capture device, treat the vendor's documentation and your own test recordings as the deciding evidence.
