 1. Use the Webhook to send the raw image on each round to a dedicated server, see [Webhook](../Webhook) resp. [../Parameter `UploadImg`](Parameters/#parameter-uploadimg).
 1. Another option is to pull the images periodically from `http://<IP>/img_tmp/raw.jpg`. Eg. with an external service. Below is a (Linux)-Bash script to do it:

 ## Use prepared images

+Instead of recoding your own images, you can use one of the selections of prepared images below.
 
 ## How does it work
 The Demo Mode tries to interfere as less as possible with the normal behavior. Whenever a Cam framebuffer gets taken (`esp_camera_fb_get()`), it replaces the framebuffer with the image from the SD card.
