If you've ever wanted to use your iPhone camera as a video & audio input to stream using OBS Studio, we've got you covered. We've tried all the apps that let you do it over WiFi, but they're not fast enough, so we also allow you to use a wired USB connection. The original one. QUALITY VIDEO Your iPhone/iPad camera's are good, really good. In fact, there’s no comparison between the highly recommended streaming webcam, the Logitech C922 HD Pro and the iPhone 6 Camera. Stream Landscape or Portrait video. AUDIO If you don't have a separate mic for your streaming setup, you can now use the microphone on your iOS device to stream audio & video. FRONT CAMERA Stream a selfie with the front camera support. Switch anytime during the stream with the familiar camera switch button. TAP TO FOCUS, PINCH TO ZOOM Controls just like you're used to from the Camera app. MANUAL CONTROLS Take control of the focus, exposure, white balance as you would on a manual DSLR camera. LOW LATENCY Stream video over a wired USB connection. This avoids the issue of delay over wifi, as many other solutions suffer from. This is just as fast as a USB webcam! USB & WIFI Choose the connection type. If you want low latency, use USB, if you'd like portability then use WiFi. WiFi is done using the NewTek™ NDI® protocol, so you can use Camera for OBS Studio with any NewTek™ NDI® compatible receiver. REMOTE CONTROL Control the app from your web browser on your computer. No need to have access to the device anymore to line up that shot perfectly. MULTIPLE DEVICES If you're lucky enough to own multiple iOS devices, use them together and produce a multi-camera stream. MAC AND PC Supports OBS Studio running on macOS and Windows. You will need to install the OBS Studio iOS Camera Plugin from our website, or use an NDI compatible receiver to use this app. For the best possible experience make sure your device is listed on our website https://obs.camera/docs/faqs/#what-ios-hardware-do-i-need MORE Subscriptions will be charged to your iTunes account at confirmation of purchase.

ReceptionRating · Positive reviews · Number of ratings

Camera for OBS Studio holds the better App Store score, 4.3 against 3.5. That said, the two scores are not equally well evidenced: Camera for OBS Studio has 3.3K ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 48% of IoT OnOff's written reviews are positive against 40% of Camera for OBS Studio's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency
