# Tripwire

The position of the tripwire in the scene.

Specify a list of points followed by the units that you want to use. The top-left pixel has the coordinates `0,0` (x-coordinates represent the distance from the left side of the frame and y-coordinates represent the distance from the top of the frame). You can separate points and coordinates with commas or spaces. For example:

`Tripwire=x1,y1 x2,y2 ...xn,yn units`.

You can choose the following units:

- `percent` or `%` to use percentages of the image or video dimensions (x-coordinates as percentages of the width, y-coordinates as percentages of the height).
- `pixels` or `px` to use numbers of pixels.
