The mobile phone ("proxy") acts as the user agent in this case with a HTTPS connection to the push service. A different protocol than HTTP may be required between phone and the camera. Sounds similar to a field gateway scenario?

Regarding "unsecured", Section 9 requires HTTPS - This protocol MUST use HTTP over TLS [RFC2818].
