Async Python Client for ONVIF Camera

Project description

python-onvif-zeep-async
============

ONVIF Client Implementation in Python

Dependencies
------------
`zeep[async] <http://docs.python-zeep.org>`_ >= 3.0.0
`aiohttp <https://aiohttp.readthedocs.io>`_ >= 1.0

Install python-onvif-zeep-async
-------------------------
**From Source**

You should clone this repository and run setup.py::

cd python-onvif-zeep-async && python setup.py install

Alternatively, you can run::

pip install --upgrade onvif-zeep-async


Getting Started
---------------

Initialize an ONVIFCamera instance
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

::

from onvif import ONVIFCamera
mycam = ONVIFCamera('192.168.0.2', 80, 'user', 'passwd', '/etc/onvif/wsdl/')
await mycam.update_xaddrs()

Now, an ONVIFCamera instance is available. By default, a devicemgmt service is also available if everything is OK.

So, all operations defined in the WSDL document::

/etc/onvif/wsdl/devicemgmt.wsdl

are available.

Get information from your camera
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
::

# Get Hostname
resp = await mycam.devicemgmt.GetHostname()
print 'My camera`s hostname: ' + str(resp.Name)

# Get system date and time
dt = await mycam.devicemgmt.GetSystemDateAndTime()
tz = dt.TimeZone
year = dt.UTCDateTime.Date.Year
hour = dt.UTCDateTime.Time.Hour

Configure (Control) your camera
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To configure your camera, there are two ways to pass parameters to service methods.

**Dict**

This is the simpler way::

params = {'Name': 'NewHostName'}
await device_service.SetHostname(params)

**Type Instance**

This is the recommended way. Type instance will raise an
exception if you set an invalid (or non-existent) parameter.

::

params = mycam.devicemgmt.create_type('SetHostname')
params.Hostname = 'NewHostName'
await mycam.devicemgmt.SetHostname(params)

time_params = mycam.devicemgmt.create_type('SetSystemDateAndTime')
time_params.DateTimeType = 'Manual'
time_params.DaylightSavings = True
time_params.TimeZone.TZ = 'CST-8:00:00'
time_params.UTCDateTime.Date.Year = 2014
time_params.UTCDateTime.Date.Month = 12
time_params.UTCDateTime.Date.Day = 3
time_params.UTCDateTime.Time.Hour = 9
time_params.UTCDateTime.Time.Minute = 36
time_params.UTCDateTime.Time.Second = 11
await mycam.devicemgmt.SetSystemDateAndTime(time_params)

Use other services
~~~~~~~~~~~~~~~~~~
ONVIF protocol has defined many services.
You can find all the services and operations `here <http://www.onvif.org/onvif/ver20/util/operationIndex.html>`_.
ONVIFCamera has support methods to create new services::

# Create ptz service
ptz_service = mycam.create_ptz_service()
# Get ptz configuration
await mycam.ptz.GetConfiguration()
# Another way
# await ptz_service.GetConfiguration()

Or create an unofficial service::

xaddr = 'http://192.168.0.3:8888/onvif/yourservice'
yourservice = mycam.create_onvif_service('service.wsdl', xaddr, 'yourservice')
await yourservice.SomeOperation()
# Another way
# await mycam.yourservice.SomeOperation()

ONVIF CLI
---------
python-onvif also provides a command line interactive interface: onvif-cli.
onvif-cli is installed automatically.

Single command example
~~~~~~~~~~~~~~~~~~~~~~

::

$ onvif-cli devicemgmt GetHostname --user 'admin' --password '12345' --host '192.168.0.112' --port 80
True: {'FromDHCP': True, 'Name': hision}
$ onvif-cli devicemgmt SetHostname "{'Name': 'NewerHostname'}" --user 'admin' --password '12345' --host '192.168.0.112' --port 80
True: {}

Interactive mode
~~~~~~~~~~~~~~~~

::

$ onvif-cli -u 'admin' -a '12345' --host '192.168.0.112' --port 80 --wsdl /etc/onvif/wsdl/
ONVIF >>> cmd
analytics devicemgmt events imaging media ptz
ONVIF >>> cmd devicemgmt GetWsdlUrl
True: http://www.onvif.org/
ONVIF >>> cmd devicemgmt SetHostname {'Name': 'NewHostname'}
ONVIF >>> cmd devicemgmt GetHostname
True: {'Name': 'NewHostName'}
ONVIF >>> cmd devicemgmt SomeOperation
False: No Operation: SomeOperation

NOTE: Tab completion is supported for interactive mode.

Batch mode
~~~~~~~~~~

::

$ vim batchcmds
$ cat batchcmds
cmd devicemgmt GetWsdlUrl
cmd devicemgmt SetHostname {'Name': 'NewHostname', 'FromDHCP': True}
cmd devicemgmt GetHostname
$ onvif-cli --host 192.168.0.112 -u admin -a 12345 -w /etc/onvif/wsdl/ < batchcmds
ONVIF >>> True: http://www.onvif.org/
ONVIF >>> True: {}
ONVIF >>> True: {'FromDHCP': False, 'Name': NewHostname}
