Synology DVA3219 is quite an impressive model. It identifies truly unusual motions while filtering out background noise including rain, snow, swaying trees, small animals, or the day/night switch of an IP camera.I wish I had time to put it to test since I have problems with cloud and shadow detection on my DS718+ sometimes. I believe it would do a better job.WD Purple is a recommended option for fir surveillance only solutions. If you plan on using regular NAS functions as well then WD Red or Ironwolf drives will do an equally good job.I have built a list with 4K 8MP cameras here:https://nascompares.com/answer/nas-compatible-4k-8mp-cameras-with-h-265-compression/Closest I would get are cameras with a port for an external mic. You can have a look.
