  • Dahua ANPR Camera. See options available from April 2021 below.
  • Laptop with connection to the same network as the camera
  • Ensure both NVR and ANPR is on the latest firmware. (As of April 2021 the latest ANPR firmware currently available is V2.625.0000000.0.R.201105)


Dahua 2MP Short Range ANPR Camera

[3M - 6M Capture Range] [3M - 4M Detected Lane Width]


Dahua 2MP Long Range ANPR Camera

[8M - 30M Capture Range] [6M - 7M Detected Lane Width]


When installing ANPR cameras, it is important the mounting height and angle of the camera is correct. Failure to mount the camera appropriately to the situation it is being utilised in will diminish the ability for the camera to read number plates accurately and efficiently.

Common errors are mounting the camera too high/low or with a horizontal/vertical angle greater than 30°.

Below are the recommended heights and angles for reference.

Scenario 1 - Standalone ANPR

In this scenario the camera is connected to a network but there is no NVR and as such the camera is installed with an SD card to provide storage. The camera is accessed directly via a PC using the cameras IP address.

Feature set available with an SD card installed:

• Capture number plate snapshots
• Supports Allow/Block lists
• Live View via direct access from PC
• Alarm output

Scenario 2 - ANPR Connected to NVR

The more traditional setup with the ANPR camera connected either directly to an NVR PoE port or via the LAN network. Depending on the recorder the ANPR camera is connected to will depend on the feature set available. It is recommended to use a NVR5000/600-4KS2 / -I series to give full functionality.

Features available when connected to 4000-4KS2 series recorders:

Direct from the NVR:

• Continuous video recording

Direct from the ANPR Camera:

• Display number plate snapshot
• Allow List
• Alarm Output
• Live View

Features available when connected to a NVR5000/600-4KS2 / -I series recorders:

Any number plate, block/allow list trigger events including:

• Recording
• NVR relay usage
• NVR buzzer
• Snapshot
• Full screen live view display
• Email support


When configuring the ANPR camera for use with an NVR or as a standalone solution, all devices should first be connected. The DHI-ITC237-PW6M-IRLZF1050-B supports PoE (802.3at) or can be powered via 12v DC.

Note: Different ANPR models may have different connections

Ethernet Port – 100/1000 RJ45 POE+ 802.3at RS-485 / RS-232
12v DC IN 24v AC IN
Alarm Inputs & Outputs Analogue Output (CVBS)
Audio Input Audio Output


Once the camera has been mounted and all required connections connected. Using a PC/Laptop connected to the same network as the camera, log into the default IP address of the camera ( to initialise the camera. Alternatively, you can use the ConfigTool within the Dahua toolbox to activate the camera and adjust the IP address if required.

Note: If the ANPR is connected directly to the NVR you will need to enable Virtual Host in the recorder to enable direct access to the camera. Different ANPR models may have different options than those shown below.

The first time you log into the ANPR you may be asked to install the web browser plugin. If prompted, install, close and re-open your browser and relog into the camera.

To configure the ANPR select the Guide tab at the top, this will go through the setup process of the camera.

Step 1 - Ensure the firmware version of the camera is correct and click OK.

Step 2 - Click the ‘Snapshot’ button to pause the live video feed with a number plate is within the green area.

Drag the Red/Yellow box over the number plate, using the guide at the bottom to match the correct size. You can digitally zoom in on the Red/Yellow box by clicking the ‘Local Range’ button.

Use the ‘Zoom’ and ‘Focus’ sliders to manually adjust the camera as required by the scene to ensure accurate recognition.

Step 3 - Select ‘Iden Area’ and click ‘Redraw´ to draw the identification box.

Do the same with ‘Snap Line’ to define at which point the snapshot is captured. Use the sample as guidance.

Step 4 - After finishing the guide, you can adjust the setup by clicking ‘Config(LPR)’ in the top right of the live view. Make sure the ‘Applicable Region’ is set correctly.

Further configuration can be done by navigating to Setting > ITC.

Navigate to ‘Snapshot Settings’. From here you can set the capture direction.

Under Intelligence > Recognition, adjust the vehicle detection sensitivity to suit the scene. A good starting point is 70.

Select ‘Scene’ and make sure the correct option is selected for the deployment in use.

From ‘Cutout’ you can adjust whether you want just the number plate or the whole vehicle.

From ‘Blocklist and Allowlist’ you can configure which specific number plates can gain access.

To add a number plate to the allow list select ‘Allowlist’ and click ‘Add’.

Enter the details of the number plate, card ID, start date and end date, owners name and click save. If you wish to add multiple at once, tick the continue adding box, alternatively you can download the template .csv file, edit and re-import the list in one go.

Under ‘Barrier Control’ you can adjust how the gate/barrier is operated. You can also manually open/close to test you have everything wired up correctly.

If the ANPR is deployed standalone and not connected either directly or over the network with an NVR you will need to put an SD card into the camera to be able to save any data.

Select Storage > Destination > Local. Click ‘Format’ to format the SD card, once complete it is ready for use.
