# Data Collection

The following video provides step-by-step instructions for setting up and using your cameras to collect data for use with Theia3D. This includes changing camera settings, synchronizing the cameras, recording data, and downloading videos from the cameras through the web interface. This tutorial demonstrates the basic functionality and recommended settings of the Sony camera control interface. Refer to the Sony documentation for information about other settings and more advanced functionality.

{% hint style="warning" %}
**NOTE:** This video recommends setting the Shoot Mode to (Movie) Program Auto, however we no longer recommend this option. To achieve crisp images without movement blur, we recommend setting the Shoot Mode to *(Movie) Manual Exposure*, which allows you to select a specific *Shutter Speed*. Using a shorter *Shutter Speed* such as 1/500 or 1/1000 will provide crisper images with limited movement blur, but may result in dark images. If your videos appear dark, adjust the ISO setting to increase the brightness of the image. If you are using ISO AUTO, you may need to increase the maximum ISO threshold to allow a sufficiently high ISO to be used.

{% hint style="danger" %}
 Using the digital zoom is not recommended, as the default Sony RX0 II intrinsic parameters built into Theia3D will no longer apply, and you will be required to obtain new intrinsic parameters for your cameras.

{% hint style="danger" %}

Sony control boxes do not provide sufficient power to charge or maintain connected cameras while they are powered ON. Place the Sony cameras into Standby between recording sessions to avoid camera shutdown or battery drain during extended operation.
