You should add it as "Generic IP Camera" (as you did) and set path to "/record/current.jpg", quick reload the router (probably also regen screen for orbiters) and that's it. You should see your camera in security line on orbiter.
If that doesn't work, please post all errors you see in /var/log/pluto/XXX_Generic_Serial_Device.newlog (where XXX is device number of your camera)
