Triggering the windshield wiper through ONVIF

[xtrdustin]

We'd like to make it possible for users of our software to trigger the windshield wiper on the Axis camera. Is this possible through ONVIF, or would we need to use the VAPIX API for it?

Thanks in advance!

Hi @xtrdustin.

I think you should be able to send GetServiceCapabilities to the camera, to see if the camera support wipers or not:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:tds="http://www.onvif.org/ver10/device/wsdl" xmlns:tt="http://www.onvif.org/ver10/schema">
  <soap:Body>
    <tds:GetServiceCapabilities />
  </soap:Body>
</soap:Envelope>

Given the camera support it, the following examples would send the ONVIF command to trigger the wiper:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:tds="http://www.onvif.org/ver10/device/wsdl" xmlns:tt="http://www.onvif.org/ver10/schema">
  <soap:Body>
    <tds:SendAuxiliaryCommand>
      <tds:AuxiliaryCommand>tt:Wiper|On</tds:AuxiliaryCommand>
    </tds:SendAuxiliaryCommand>
  </soap:Body>
</soap:Envelope>

Thanks, that worked! Specifically, I had to call the methods on the Device service (as opposed to the PTZ or Media services). There were also commands that turn the camera's IR mode on/off (or back to auto):

   misc=org.onvif.ver10.device.wsdl.MiscCapabilities@182e4365[
      auxiliaryCommands=[
         tt:IRLamp|On,
          tt:IRLamp|Off,
          tt:IRLamp|Auto,
          tt:Wiper|On,
          tt:Wiper|Off
      ],

Hi @mattias-kindborg-at-work,

As a follow-up to this thread, do you know if there's a way to get the wiper status (either whether it's currently on, or how much longer is left in the cycle), through ONVIF?

Thanks,
Dustin
