The client for HIKVISION cameras, DVR

Python Library for Hikvision Cameras

Simple and easy to use library for working with video equipment from Hikvision.

Install

pip install hikvisionapi

Examples

There are two formats for receiving a response:

from hikvisionapi import Client

cam = Client('http://192.168.0.2', 'admin', 'admin')


# Dict response (default)
response = cam.System.deviceInfo(method='get')

response == {
    u'DeviceInfo': {
        u'@version': u'2.0',
        '...':'...'
        }
    }


# xml text response
response = cam.System.deviceInfo(method='get', present='text')

response == '''<?xml version="1.0" encoding="UTF-8" ?>
        <DeviceInfo version="1.0" xmlns="http://www.hikvision.com/ver20/XMLSchema">
        <deviceName>HIKVISION</deviceName>
        </DeviceInfo>'''

Hints:

# to get the channel info
motion_detection_info = cam.System.Video.inputs.channels[1].motionDetection(method='get')


# to send data to device:
xml = cam.System.deviceInfo(method='get', present='text')
cam.System.deviceInfo(method='put', data=xml)


# to get events (motion, etc..)
# Increase timeout if you want to wait for the event to be received
cam = Client('http://192.168.0.2', 'admin', 'Password', timeout=30)
cam.count_events = 2 # The number of events we want to retrieve (default = 1)
response = cam.Event.notification.alertStream(method='get', type='stream')

response == [{
    u'EventNotificationAlert':{
        u'@version': u'2.0',
        u'@xmlns': u'http://www.hikvision.com/ver20/XMLSchema',
        u'activePostCount': u'0',
        u'channelID': u'1',
        u'dateTime': u'2018-03-21T15:49:02+08:00',
        u'eventDescription': u'videoloss alarm',
        u'eventState': u'inactive',
        u'eventType': u'videoloss'
        }
   }]

# Alternative solution to get events
cam = Client('http://192.168.0.2', 'admin', 'Password', timeout=1)
while True:
    try:
        response = cam.Event.notification.alertStream(method='get', type='stream')
        if response:
            print response
    except Exception:
        pass

# to get opaque data type and write to file
response = cam.System.configurationData(method='get', type='opaque_data')
with open('my_file', 'wb') as f:
    for chunk in response.iter_content(chunk_size=1024): 
        if chunk:
            f.write(chunk)
            
# Get and save picture from camera            
response = client.Streaming.channels[102].picture(method='get', type='opaque_data')
with open('screen.jpg', 'wb') as f:
    for chunk in response.iter_content(chunk_size=1024):
        if chunk:
            f.write(chunk)                

Examples (Async)

from hikvisionapi import AsyncClient

cam = AsyncClient('http://192.168.0.2', 'admin', 'admin')


# Dict response (default)
response = await cam.System.deviceInfo(method='get')

response == {
    u'DeviceInfo': {
        u'@version': u'2.0',
        '...':'...'
        }
    }


# xml text response
response = await cam.System.deviceInfo(method='get', present='text')

response == '''<?xml version="1.0" encoding="UTF-8" ?>
        <DeviceInfo version="1.0" xmlns="http://www.hikvision.com/ver20/XMLSchema">
        <deviceName>HIKVISION</deviceName>
        </DeviceInfo>'''

# to send data to device:
xml = cam.System.deviceInfo(method='get', present='text')
await cam.System.deviceInfo(method='put', data=xml)


# to get events (motion, etc..)
# Increase timeout if you want to wait for the event to be received (None for infinite)
async for event in cam.Event.notification.alertStream(method='get', type='stream', timeout=None):
    event == {
        u'EventNotificationAlert':{
            u'@version': u'2.0',
            u'@xmlns': u'http://www.hikvision.com/ver20/XMLSchema',
            u'activePostCount': u'0',
            u'channelID': u'1',
            u'dateTime': u'2018-03-21T15:49:02+08:00',
            u'eventDescription': u'videoloss alarm',
            u'eventState': u'inactive',
            u'eventType': u'videoloss'
            }
    }

# Get and save picture from camera
with open('screen.jpg', 'wb') as f:
    async for chunk in cam.Streaming.channels[102].picture(method='get', type='opaque_data'):
        if chunk:
            f.write(chunk)

How to run the tests

pipenv install --dev
pipenv run pytest
pipenv run pytest --cov-report html --cov hikvisionapi # to get coverage report in ./htmlcov/

# or you can get into the virtual env with:
pipenv shell
