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
