<!--#echo var="DATE_LOCAL" --> <!--#fsize file="snapshot.jpg" --> <!--#flastmod file="camera_feed.jpg" --> When you view the page, the server expands these into:
wget --user=admin --password=yourpass http://192.168.1.100/view/index.shtml Then parse the .shtml file to extract the actual image URL (often snapshot.jpg or live.jpg ). Write a script that checks the timestamp every minute. If the timestamp hasn't changed for 10 minutes, send an alert (camera might be frozen). view index shtml camera updated
