    <p>A node to discover IP devices which support the ONVIF specifications.</p>
    <p>The discovery can be started by sending an input message.  A broadcast takes about 3 seconds in normal circumstances.  The input message will be ignored if another broadcast is already active.</p>
    <p><strong>Timeout:</strong><br/>
    The timeout is the number of seconds we will wait for OnVif devices to respond.  After the timeout interval, the broadcast will be considered completed.  Any device responses afterwards will be ignored.</p>
    <p><strong>Separate output message for each device:</strong><br/>
    When deselected a single output message will be generated, with <code>msg.payload</code> containing an array of available all devices. When deselected, a separate output message will be generated for every available device.</p>
