I don't see a Defender model Camera in the options to add camera. Any chance there will be an option for it?
The developer offers a page to check what camera models are supported by the application. I have accessed the page and searched for Defender cameras, but there aren't anything available. This could happen because no one asked for support or the cameras are not supported by default.
You can check the list using the following URL: http://www.deskshare.com/ip-cameras-manufacturers-models.aspx
Additionally, contact the developer and request this features to be added to later versions of the software: http://www.deskshare.com/contact_us.aspx
