Knowledge base 149: ANPR cameras in Identity Access 9
Within Identity Access it is possible to integrate an ANPR camera to operate a barrier. This makes the integration of an ANPR camera seamless for an end user as reporting and adding of new number plates is in the same User Interface as their access control tokens. Number plates are stored under the users secondary tokens meaning they will appear when reporting on a users activity.
Identity Access works with cameras supporting a Wiegand output in the SHA-1 26-Bit Format. Below we show what ANPR cameras we have tested with.
This process has been tested and implemented with:
HIKVISION ANPR camera model numbers:
DS-2CD7A26G0/P-IZHSWG
DS-2CD7A26G0/P-IZHSWG-8-32MM
iDS-TCM403-AI/0411
iDS-TCM403-AI/0832
Dahua ANPR camera model numbers:
DHI-ITC416-PL8I-IZ
1. Camera Installation
Install the ANPR camera as per the manufacturer's instruction manual. Example on how to install and configure a Hikvision ANPR camera can be found in the Appendix.
1.1 Connection with the iNet Door Controller
1. The connections for the ANPR Camera and Reader port using a Belden 9538 reader cable (as per Controlsoft's specification) on the iNet are as follows:
Blue wire: D1 at ANPR – Data 1 on iNet ACU Reader Port
Yellow wire: D0 at ANPR – Data 0 on iNet ACU Reader Port
Black wire: GND at ANPR – GND on iNet ACU Reader Port
3. Run the IA Configuration application from System > Configuration
Follow the screenshot and the instructions below -
1) Select Cards & Readers
2) Select ANPR
3) Select Use HIK Vision ANPR
4) Select Which secondary token field you wish to store the ANPR number plate
5) Click
Accept 2. Adding a Number Plate to a User
1. Add or Edit a User in Identity Access and select Tokens (shown below), here you will now see the ANPR option, type in the required number plate and click Accept.
It is only possible to store 1 number plate per user using the in built algorithm, however using the Secondary Token field it is possible to perform a conversion and store the number plate in its decimal number format into any of the other secondary token fields.

3.1 Image Settings
There are two modes on the ANPR camera, Road and Normal, as follows, It is recommended to use Road Mode to monitor the road traffic, or if the external environment is too dark at night, Road Mode is also recommended, as follows, Pic 1.

In addition, you can also manually modify/configure the image parameters according to different scenarios, as follows, Figure 1.

3.2 ANPR settings
Configuration >Road Traffic > Tick the Enable box to enable the ANPR feature, and click and drag the yellow lane line to set the position, adjust the zoom ratio of the camera so that the size of the vehicle in the image is close to that of the red frame, Pic 2.

Next choose Wiegand from the menu shown below, tick Enable and choose SHA-1 26bit as shown below -
3.4 Installation angle
When ensuring the camera is set up correctly and the best field of view is set with the lens – make sure the tilt angle of the plate to the horizontal plane is not more than 5 degrees, otherwise you will get poor or incorrect read’s. This road is uphill and with an adverse camber, which causes an offset of the plate to the horizontal plane – this plate still read perfectly well, but with anything more than this there could be problems so check your scene before hand.
