Works just fine with the Synology Surveillance Sattion with the settings:
Brand: [ONVIF]
Camera Model: Generic_ONVIF
Port: 8999
Operate the device with a PoE adapter from TP-Link. Works perfectly so far.
So you have to carry only one network cable to the camera - an electrical outlet not needed there.
The camera is very compact - the image quality with 720p in my opinion, very well - during the day with "ambient light" - at night with the built-in infrared LEDs (see photo)
Streaming directly with VLC possible with URL: rtsp: //IPADRESSE/ch2_0.h264
I'm going to have to buy a second for monitoring our terrace.
Unfortunately, the camera loses during a power failure the set time - but do not mind particularly because I am doing this anyway with a Synology.
