Power Options

ScreenPort SDI offers multiple power options for its operation:

USB-C Power Adapter (included)

When portability is not an issue, ScreenPort SDI can be powered using included AC/DC power adapter. Moreover, power will be passed to iOS device allowing users to charge it. Power adapter accepts input of 100-240V, 50/60Hz, 0.55A max and produces output of 5V 3A.

Battery slots

The most portable powering option is to use on-board batteries. ScreenPort SDI has two battery slots for Sony NP-F style batteries. Users can opt for original Sony NP-F970 (7.2V, 7800mAh), or compatible batteries from other brands. Some vendors offer NP-F batteries with lower capacity and smaller size, which may be more suitable in some cases. Please note that ScreenPort SDI cannot charge batteries.

USB-C Power Bank

More portable powering option is to use external battery or power bank. Compatibility requirement for power bank is 5V 3A USB-C power output.

Computer USB

When used with computer, USB connection can be used to transfer both data and power, so no additional power source is needed for ScreenPort SDI operation.


ScreenPort SDI contains 3 holes at the bottom side of the device for custom mounting accessories. Holes will fit 2.2mm self-tapping screws.

Getting started

Follow these steps to use ScreenPort SDI connected via USB cable to iOS device or Mac:

  1. Install ScreenPort or QTAKE Monitor application on your iOS device.
  2. Connect power source to ScreenPort SDI device using USB-C power connector or insert charged battery into designated slot.
  3. Power on ScreenPort SDI device using the power switch (status LED will turn white). Power up sequence takes around 20 seconds.
  4. Connect SDI output of the camera to SDI input of the ScreenPort SDI using SDI cable (status LED will turn green if the valid signal is detected).
  5. Connect USB-C data port of the ScreenPort SDI to your iOS device using data cable.
  6. “Trust This Computer?” dialog will appear on your iOS device. Click the “Trust” button.


ScreenPort SDI offers multiple ways to connect to a host device.


Connecting ScreenPort SDI USB data port to your host device provides the connection with the highest bandwidth. This means you can use the best visual quality without worrying your data connection will drop frames. The downside of the USB interface is the limitation to a single device.


If you need to connect multiple ScreenPort SDI devices to multiple host devices, ethernet interface is the solution. When connected to your network with an ethernet cable, signal from each ScreenPort SDI will be available to any device connected to the same network.


Similar to ethernet, Wi-Fi interface is used to connect to your network, but this time wirelessly. This is the most practical way to stream from ScreenPort SDI to monitoring devices. However, it is also the most fragile way to connect, because data packets can be easily dropped due to lower signal quality or interference.

Access Point Mode

Access Point Mode transforms how you can use your ScreenPort SDI device. Instead of relying on existing Wi-Fi infrastructure, ScreenPort can create its own Wi-Fi network with support for up to 2 wireless clients. This mode requires firmware 2.54 or higher and ScreenPort app 1.6 or higher.

New devices ship with Access Point Mode enabled by default. To enable Access Point Mode on your existing ScreenPort SDI device, open the ScreenPort app and tap SETUP, then tap Network and set Access Point to ON.

When you need to connect to an on-set Wi-Fi network, set Wi-Fi to ON instead. This will automatically turn Access Point off, but your settings will be retained for future use.

ScreenPort app

ScreenPort SDI device can be operated using the ScreenPort application. When connected to iOS device, ScreenPort SDI will be automatically detected. Basic functionality for monitoring, recording and playback is described below.


Make sure that the LIVE/DISK button located in the top left corner is set to live mode. Viewer will display the image of the incoming SDI feed. FORMAT label located in the top bar will show the format of the SDI signal.

Audio Meters

If SDI signal contains audio, meters above the image viewer will show the audio level of the live signal. During playback, meters will show the audio levels of the playback.


If the SDI signal contains camera metadata, ScreenPort SDI will extract them and display them in UI toolbars. Timecode and clip name is located in the bottom part of the screen. Camera and lens metadata is located in the top part of the screen.


When the view is in the LIVE mode, you can tap the white circle icon to initiate recording session. Incoming video and audio signal will be recorded into a media file. Tap the record icon again to finish recording. If the SDI signal contains timecode, it will be recorded too. In case of missing timecode, current time of day will be used instead.


In addition to manual recording, some cameras provide SDI record flags that can be used to initiate automatic recording. To set the ScreenPort SDI to auto-record mode, tap the AUTO REC button (ARRI and SONY cameras are currently supported).


Tap the VIEW/CLIPS button in the bottom left corner to show the clip browser. Use the DAYS/CLIPS button in the top left corner to switch between days and clips mode. Each day item represent folder that contain all clips shot during that day. Tap the day thumbnail to show corresponding clips.
