1Introduction
This manual is about the Wiegand configuration and features of network cameras.
The manual is created as a guide for the technical support engineer, sales engineer, etc.
Currently overseas license plate cameras support 4 Wiegand protocols: Card ID 26-bit
Wiegand protocol, Hik 34-bit Wiegand protocol, NEWG 72bit Wiegand protocol and
SHA-1 26-bit Wiegand protocol. The various protocols are explained as follows.

3Transfer Plate Number via Wiegand
Protocol
3.1 Card ID 26-bit
3.1.1 Protocol Standard
Map the license plate number with the access control card number.
Find the related card number in allowlist and blocklist, and transfer the card information
(26 bit) via Wiegand interface.
Determine whether the car has permission to pass according to the card ID.
Compatible with any standard access control system which supports standard Wiegand
26-bit protocol.
Card No. Encoding Mode:
1. The ID number should have 8 digits in total. The first 5 digits are Card ID, the last 3
digits are Site Code.
2. The value range for Card ID are: 0-65535, the value rage for Site Code are 0-255.
3. If you enter a number more than 8 digits, the last 8 digits will be kept. For example, if
you enter 98984 2118, the effective number will be 89842 118.
4. If you enter a number less than 8 digits, 0 will be added before the number until it is a
8-digit number. For example, 984 2119 will be saved as 09842 119.
Figure 3-1 Card ID No. Encoding Mode
Format Description:
The 26-bit Wiegand format contains 2 parity bits and 24 data bits.

Bit 1 is an even parity bit for the first 12 bits (bit 2 to bit 13).
Bit 26 is an odd parity bit for the last 12 bits (bit 14 to bit 25).
Bit 2 to bit 9 is site code in binary format, if the site code ID is less than 8 digits, 0
will be added before the ID until it is 8-digit number.
Bit 10 to bit 25 is site code in binary format, if the card ID is less than 8 digits, 0 will
be added before the ID until it is 16-digit number.
Example:
Here we take card number: 12345 011 as example.
The coding process are show as below.
Steps:
Split the card number as the card ID (12345) and site code (011).
1. Convert 12345 to binary format, as: 0011000000111001.
2. Convert 011 to binary format, as: 00001011.
3. Site data and card data as: 0000 1011 0011 0000 0011 1001.
4. Bit 1 is an even parity bit for the first 12 bits (bit 2 to bit 13), as 1.
5. Bit 26 is an odd parity bit for the last 12 bits (bit 14 to bit 25), as 1.
6. According to the converting mode(Even parity bit + site data + card data + odd
parity bit), you can get a binary code as: 1 00001011 0011000000111001 1.

-Make sure there are no repeated plate number and/or Card No. in the list.
3.2 Hik 34bit
3.2.1 Protocol Standard
Map the license plate number with the access control card number.
Find the related card number in allowlist and blocklist, and transfer the card information
(34 bit) via Wiegand interface.
Determine whether the car has permission to pass according to the card number.
The protocol for directly transferring the access control card No. through the Wiegand
interface is a private protocol of Hikvision, compatible with Hikvision access control
system.

Card No. Encoding Mode:
Support up to 10-digit card number. If you enter a card number of more than 10 digits,
only the first 10 digits are kept. Currently, the maximum supported card number is
2147483647.
Format Description:
The 34-bit Wiegand format contains 2 parity bits and 32 data bits.

The return result (even parity bit + card data +odd parity bit) will be sent to
Hikvision access control device supporting Wiegand protocol.
The front parity bit is the even parity bit of the first 16 bits of the card number.
The rear parity bit is the odd parity bit of the last 16 bits of the card number.
Example:
Take Card number:1234567890
The coding process are show as below.
1. Convert 1234567890 to hexadecimal format, as: 0x49 0x96 0x02 0xD2.
2. Convert 0x49 0x96 0x02 0xD2 to binary format, as: 0100 1001 1001 0110 0000
0010 1101 0010.
3. Bit 1 is an even parity bit for the first 16 bits (bit 2 to bit 17), as 1.
4. Bit 34 is an odd parity bit for the last 16 bits (bit 18 to bit 33), as 0.
5. According to the converting mode(even parity bit + card data + odd parity bit), you
can get a binary code as: 10100 1001 1001 0110 0000 0010 1101 0010 0

3.3 SHA-1 26bit
3.3.1 Protocol Standard
The Wiegand interface directly transmits the license plate number, and performs a hash
operation on the license plate number.
The 24 bits are taken through the Wiegand standard interface, and an even parity bit
and an odd parity bit are added before and after the 24 bits respectively according to
the standard 26 bit protocol. The result will be sent to Wiegand access control (third
parties like Paxton or Salto) equipment.
Compatible directly with access control system and platform of Paxton in the UK and
Salto in Europe.
