Http binary sensor with simple url

I would like my foscam camera to report any motion to a virtual sensor. All the examples I have found depends on a json request. The foscam camera can only do a simple http request with parameters:

First check the current settings:
The hidden variables of interest are “http” and “http_url”

To set these values:
encoded_url should be the url used to trigger your virtual motion detector.
Make sure you encode the url!

Does the request send from the camera looks like this one?
