MacGyver yes, loops recording to beginning and re-writes new data. OR you can stop recording when HDD is full (menu option). DVR unit does NOT have HDD installed.

MacGyver i have the same WD purple hdd.. and i get the same issue.. motion detection isn't always sensitive and the playback stops early (or doesn't detect movement from a distance at night). most of the time it works well. PTZ camera works a little better than bullet camera. i dont know how to resolve this.

MacGyver no. no major heat issues. it gets warm but not hot. i have it sitting ontop of my shelf with free air flow. it is silent, there is no fan. i still use it, and it works very well for YuTube, Ntflix, Sptify etc

MacGyver yes. i do not use ethernet or wifi internet, just standalone. you may see a small warning icon in the bottom left corner when there is no internet. unit works fine without internet.. you can use usb to upgrade backup.

MacGyver very sharp. very precise. cuts perfect on small diameter wire.
