# Region

The region of the scene that you want to monitor.

Specify the region as a comma-separated list of values in the order: `left,top,width,height`, followed by the units that you want to use.

- `left` is the distance from the left of the frame to the left edge of the region.
- `top` is the distance from the top of the frame to the top edge of the region.
- `width` is the width of the region.
- `height` is the height of the region.

You can choose the following units:

- `percent` or `%` to use percentages of the image or video dimensions (`left` and `width` as percentages of the width, `top` and `height` as percentages of the height).
- `pixels` or `px` to use numbers of pixels.

To specify a non-rectangular region, set FreeformRegion instead.
