How to PTZ over ONVIF for ASH21-W-V2

charmonium · Post by **charmonium** » Sat Oct 07, 2023 10:28 am

I am trying to write an ONVIF application that targets my ASH21-W-V2. I can connect to the ONVIF endpoint on the ASH21-W-V2, but that endpoint does not supply any pan/tilt/zoom service.

curl \
  -X POST \
  10.0.0.95/onvif/device_service \
  -d $'<?xml version=\'1.0\' encoding=\'utf-8\'?>

I understand this response should have a tt:PTZCapabilities element with a tt:XAddr, so that I can control PTZ over the ONVIF API. However, PTZ works in the Amcrest SmartHome app, and it is advertised to work in BlueIris. So how does the Amcrest SmartHome and BlueIris control PTZ if not by ONVIF?
