Capturing HTTP traffic for Home Assistant ONVIF

On the Home Assistant host (if you have SSH access):

# Replace 192.168.1.100 with your camera's IP
sudo tcpdump -i any -s 0 -w onvif_capture.pcap host 192.168.1.100

Use Wireshark on any computer on the same network

  • Start capture with filter: host 192.168.1.100 (your camera IP)
  • Restart/reload the ONVIF integration in HA
  • Stop capture after the error occurs
  • Save as .pcapng file

Testing with curl

curl 'http://<user>:<password>@<camera-ip>:<camera-port>/onvif/media_service' --header "Content-Type: application/soap+xml; charset=utf-8" --data '<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:trt="http://www.onvif.org/ver10/media/wsdl"><soap:Body><trt:GetProfiles/></soap:Body></soap:Envelope>'
