I assume this will also work with IP camera system.
It depends on which system. Some of the systems do not directly support remote login with the iphone, but you can still access the camera directly (outside of the recorder) to see a live image from the iphone.
Is there anyway to use a mac computer with this software as the recording media and have the cameras go hardwired into a router or wireless router.
Unfortunately, you can not use a MAC with the recording software, but you can view the cameras from a MAC in the safari web browser
