I have one of the old-school DVR systems from back in 2011-2012; the cameras more or less suck on them (SD, fixed focus optics, and really crappy night vision capabilities) and the head unit has enough security flaws and holes that it never got connected to my home network after I moved. (Hell, I didn’t even bother putting it back up until 2014 or so due to some… chaos with a now-former roommate)
Not totally sold on the Alledged Intellegence part of the cameras, but if I were to replace what I have, it’d be a ubiquiti system- All I’d need is the cameras and a small PoE switch to drive them and uplink back to the rest of the place, as I already have a capable CloudKey unit that runs the rest of my home network stack.
