ONVIF Device Service Protocol Properties

ONVIF Protocol

All properties in the Onvif protocol field are defined by internal device information and some user defined information.

Property Description EdgeX Value Type
Address The IP address of the camera. String
Port The internet port of the camera. String
EndpointRefAddress A GUID used to indentify the camera endpoint. String
DeviceStatus The discovery and authentication status of the camera. String
     UpWithAuth The device can execute commands requiring credentials.
     UpWithoutAuth The device can only execute commands that do not require credentials. Usually this means the camera's credentials have not been registered with the service yet, or have been changed.
     Reachable The device can be discovered but no commands can be received.
     Unreachable The device cannot be seen by service at all. Typically, this means that there is a connection issue either physically or with the network.
LastSeen The time that the device was last seen on the network. String
MACAddress The MAC address of the camera. String
FriendlyName The user defined name for the camera. String
Manufacturer The manufacturer of the camera. String
Model The model description of the camera. String
FirmwareVersion The firmware version of the camera. Format will vary by manufacturer and model. String
SerialNumber The serial number of the camera. String
HardwareId The hardware ID of the camera. String

Custom Metadata Protocol

All properties in the CustomMetadata protocol field are user defined. It can hold multiple different entries. For more information, see here

How does the device service work?

The Onvif camera uses Web Services standards such as XML, SOAP 1.2 and WSDL1.1 over an IP network. - XML is used as the data description syntax - SOAP is used for message transfer - and WSDL is used for describing the services.

The spec can refer to ONVIF-Core-Specification.

For example, we can send a SOAP request to the Onvif camera as below: 

curl --request POST 'http://192.168.12.128:2020/onvif/service' \
--header 'Content-Type: application/soap+xml' \
--data-raw '<?xml version="1.0" encoding="UTF-8"?>

Since the SOAP message is an HTTP call, the device service can just do the transformation between REST(JSON) and SOAP(XML).

For the concept of implementation: - The device service accepts the REST request from the client, then transforms the request to SOAP format and forward it to the Onvif camera. - Once the device service receives the response from the Onvif camera, the device service will transform the SOAP response to REST format for the client.
