Most DVR units broadcast a stream per camera so you can setup each camera in ispyconnect separately, although some units take a little bit of digging to find the streams. Using ispyconnect you can have various cameras all in one central location, have a search of the camera database they've built up.
Using the web interface of ispyconnect to then pass into HomeGenie add's in a little complexity and there could make both solutions unreliable. Having a single source for both HA and CCTV is a solution I'd like to aim for.
I believe there is also an API available, so there are ways and means of getting the two applications talking to each other.
