Actually, all the Amcrest software is, um, inadequate. I don't 'like' any of it and no single progam is capable of accessing everything I need to get to.
The Webui seems to work best for setup and ASP seems to work best for working with the actual recordings.
I did set it up as you suggested. I have the 2 IVS rules per ch, the large 24/7 intrusion zone and the smaller night time one that turns on the lights and I also turned on the full time sub channel recording.
The smaller D1 recordings don't seem to be using too much space. The system is setup to keep 15 minute files and to overwrite when full. It looks like the 2TB HDD in the NVR will be able to hold more then a weeks worth which will be fine. I still don't have the 5th camera hooked up, waiting on the cable, but it points at the front door and deosn't get triggered very often as we usually enter/exit through the garage.
I do have a spare (i7-4790K) PC that could run a PC-NVR 24/7.
Are you saying that I can setup motion detection on a seperate PC-NVR connected via the LAN that will record from the main ch and that the IVS triggers on the Amcrest NVR will still function normally even while the PC-NVR is actively recording motion triggered (not SMD) events?
Would 5GHz WiFi be enough for the PC-NVR?
