> Use outside of the ambient conditions could cause the device to fail and/or function incorrectly. These ambient conditions are applicable for the environment immediately around the device under all operational conditions. When used with an external enclosure, active temperature control and/or other cooling solutions are recommended to ensure the device is maintained within these ranges. The device design features a cooling channel in between the front section and rear sleeve. When you implement the device, make sure this cooling channel is not obstructed.

| RGB Camera Resolution (HxV) | Aspect Ratio | Format Options | Frame Rates (FPS) | Nominal FOV (HxV)(post-processed) |
The RGB camera is USB Video class-compatible and can be used without the Sensor SDK. The RGB camera color space: BT.601 full range [0..255].
