I have it for 4 months now, it is overall nice, but not that perfect...
Pros:
* Camera quality are very good at daylight and at night
* floodlight is very bright that make all my camera shoot night vision in colors. you also may control the brightness
* floodlight can be trigger by PIR
* Can save video continues or motion detection on SD or cloud
* Video recorded by motion detection save the previous 10 seconds
* can check the stream locally

* I was able to control via hikvision iVMS-4200, and found most of the staff that is ok for Ezviz DB1
* limited connection to IFTTT/ Google Home / Alexa
- For triggered, only motion trigger, it is useless with IFttt, it is very slow, if your camera trigger many time in short period
Cons:
* As Ezviz DB1 it also doesn't support ONVIF or has port 80 open..
* Motion detection is not based on the PIR, it is only based on image change, which means many false positive alarms ... using iVMS-4200 doesn't show any setting for the floodlight, seems that controller for floodlight and camera is completely separate.
* No option to control how much time the floodlight will be on after detecting human or animal..
