pyzk

pyzk is an unofficial library of zksoftware the fingerprint attendance machine.

Installation

replace original pyzk, if it was installed pip install -U git+https://github.com/kurenai-ryu/pyzk.git

or clone and execute: python setup.py install

or in your project, append the path of this project

import sys
import os
sys.path.insert(1,os.path.abspath("./pyzk"))
from zk import ZK, const

Documentation

Api Usage

Just create a ZK object and you will be ready to call api.

• Basic Usage

from zk import ZK, const

conn = None
zk = ZK('192.168.1.201', port=4370, timeout=5, password=0, force_udp=False, ommit_ping=False)
try:
    print ('Connecting to device ...')
    conn = zk.connect()
    print ('Disabling device ...')
    conn.disable_device()
    print ('Firmware Version: : {}'.format(conn.get_firmware_version()))
    # print '--- Get User ---'
    users = conn.get_users()
    for user in users:
        privilege = 'User'
        if user.privilege == const.USER_ADMIN:
            privilege = 'Admin'

        print ('- UID #{}'.format(user.uid))
        print ('  Name       : {}'.format(user.name))
        print ('  Privilege  : {}'.format(privilege))
        print ('  Password   : {}'.format(user.password))
        print ('  Group ID   : {}'.format(user.group_id))
        print ('  User  ID   : {}'.format(user.user_id))

    print ("Voice Test ...")
    conn.test_voice()
    print ('Enabling device ...')
    conn.enable_device()
except Exception as e:
    print ("Process terminate : {}".format(e))
finally:
    if conn:
        conn.disconnect()

• Connect/Disconnect

conn = zk.connect()
conn.disconnect()

• Disable/Enable Connected Device

conn.disable_device()
conn.enable_device()

• Get and Set Time

from datetime import datetime

zktime = conn.get_time()
print zktime

newtime = datetime.today()
conn.set_time(newtime)

• Ger Firmware Version and extra information

conn.get_firmware_version()
conn.get_serialnumber()
conn.get_platform()
conn.get_device_name()
conn.get_face_version()
conn.get_fp_version()
conn.get_extend_fmt()
conn.get_user_extend_fmt()
conn.get_face_fun_on()
conn.get_compat_old_firmware()
conn.get_network_params()
conn.get_mac()
conn.get_pin_width()

• Get Device use and free Space

conn.read_sizes()
print(conn)
#also:
conn.users
conn.fingers
conn.records
conn.users_cap
conn.fingers_cap
conn.records_cap

• User Operation

# Create user
conn.set_user(uid=1, name='Fanani M. Ihsan', privilege=const.USER_ADMIN, password='12345678', group_id='', user_id='123', card=0)
# Get all users (will return list of User object)
users = conn.get_users()
# Delete User
conn.delete_user(uid=1)

there is also an enroll_user() (but it doesn't work with some tcp ZK8 devices)

• Fingerprints

# Get  a single Fingerprint (will return a Finger object)
template = conn.get_user_template(uid=1, temp_id=0) #temp_id is the finger to read 0~9
# Get all fingers from DB (will return a list of Finger objects)
fingers = conn.get_templates()

# to restore a finger, we need to assemble with the corresponding user
# pass a User object and a list of finger (max 10) to save

conn.save_user_template(user, [fing1 ,fing2])

• Attendance Record

# Get attendances (will return list of Attendance object)
attendances = conn.get_attendance()
# Clear attendances record
conn.clear_attendance()

• Test voice

conn.test_voice(index=10) # beep or chirp

• Device Maintenance

# shutdown connected device
conn.power_off()
# restart connected device
conn.restart()
# clear buffer
conn.free_data()

• Live Capture!

# live capture! (timeout at 10s)
for attendance in conn.live_capture():
    if attendance is None:
        # implement here timeout logic
        pass
    else:
        print (attendance) # Attendance object
    #if you need to break gracefully just set
    #   conn.end_live_capture = True
    # on interactive mode,
    # use Ctrl+C to break gracefully
    # this way it restores timeout
    # and disables live capture

Test Machine

usage: ./test_machine.py [-h] [-a ADDRESS] [-p PORT] [-T TIMEOUT] [-P PASSWORD]
                         [-f] [-t] [-r] [-u] [-l] [-D DELETEUSER] [-A ADDUSER]
