python-kasa is not able to discover the EC60 smart camera device. Running kasa --debug --device-family SMART.IPCAMERA discover shows DEBUG:kasa.discover:[DISCOVERY] Unable to find device type for 192.168.0.XXX: Unable to find the device type field!. So I checked the device info struct and see it has one more nest of system:

{
  "system": {
    "get_sysinfo": {
      "system": {
        "stream_version": 2,
        "sw_ver": "2.3.22 Build 20230731 rel.69808",
        "hw_ver": "4.0",
        "type": "IOT.IPCAMERA"

I can create a PR, including an new fixture.
