Introduction
This is a python module for interacting with Hikvision IP cameras and NVRs. Most rebadged models work as well with full functionality. It provides two ways to talk to a device:
HikCamera- connects to a device's ISAPI event stream and tracks event/sensor state changes in real time (motion, line crossing, tamper, I/O, disk errors, etc.), with callbacks on updates. Also supports snapshots, RTSP stream URLs, motion detection toggling, and recording search/download.ISAPIClient- a synchronous ISAPI client for querying and controlling a device: device info/capabilities, storage devices, streaming channels, cameras, I/O ports, event enable/disable, snapshots, RTSP URLs, holiday mode, and reboot.
Code is licensed under the MIT license.
Requirements
- Python 3.9+
- requests >= 2.20.0
Optional:
xmltodict>= 0.13.0 - required forISAPIClient(install with theisapiextra)- pyDispatcher 2.0.5 - only needed if you want
HikCamerato also broadcast updates viapydispatchsignals; the built-in callback mechanism (add_update_callback) works without it
Installation
pip install pyhik
To also use ISAPIClient:
pip install pyhik[isapi]
Usage - Event streaming (HikCamera)
import pyhik.hikvision as hikvision
camera = hikvision.HikCamera('http://X.X.X.X', port=80, usr='admin', pwd='1234')
# Register a callback, then start the event stream processing thread
camera.add_update_callback(lambda msg: print('Update:', msg), camera.get_id)
camera.start_stream()
print(camera.get_name, camera.current_event_states)
# ...when finished
camera.disconnect()
Callbacks
add_update_callback(callback, msg)- register a callback function, called withcam_id.event_type.channelwhenever a tracked event changes state.
Properties
get_id- unique camera/NVR idget_name- camera/NVR nameget_type- device type (CAMorNVR)current_event_states- dictionary of all tracked events and their current statecurrent_motion_detection_state- current motion detection on/off statestream_connected- whether the event stream is currently connected
Functions
start_stream()- start the event stream processing threaddisconnect()- close the event stream session and stop the processing threadget_channels()- list available channelsget_motion_detection()/enable_motion_detection()/disable_motion_detection()- read/toggle motion detectionget_snapshot(channel=1)- fetch a JPEG snapshot for a channelget_stream_url(channel=1, protocol='rtsp', stream_type=1)- build an RTSP stream URLfetch_attributes(event, channel)- get the state list for a specific sensor/channelget_recording_days(track_id, start_date, end_date)- list days that have recordingssearch_recordings(track_id, start_time, end_time, max_results=100)- search for recordings in a time rangedownload_recording(playback_uri, output_stream=None, chunk_size=65536)- download a recording found viasearch_recordings
Usage - Device control (ISAPIClient)
from pyhik.isapi import ISAPIClient
with ISAPIClient('X.X.X.X', port=80, username='admin', password='1234') as client:
print(client.get_device_name(), client.get_firmware_version())
print(client.get_capabilities())
snapshot = client.get_snapshot(channel=1)
rtsp_url = client.get_rtsp_url(channel=1)
Functions

TODO
- Support IR day/night status and ability to switch between day/night/auto
