Road AI “Generic Event” setup for Hanwha NVR
This guide will walk you through the steps involved in the Road AI application setup menu, as well as on the NVR setup menu to be able to receive generic events in the NVR.
- Setup from the Camera side.
- Make sure you have a compatible camera that is running the Wisenet Road AI Open platform application with the latest firmware.
- Firmware: PNO-A9081RLP / PNV-A9081RLP: 1.41.00_20210716_R140
PNB-A9001LP (PNB-A9091RLPH): 1.41.02_20221019_R150 - Wisenet Road AI app: V7.27.678.1045
- Make sure the NVR has the latest firmware according to the respective model.
- Check the time & date, daylight savings, time zone, and NTP settings. It is recommended to sync the camera’s clock to the NVR’s NTP server when enabled.
- From the Road AI Open platform application (Camera Webpage > Setup > Open Platform > Go App) in the Settings menu define the NVR parameters:
- Enable NVR integration
- Enter NVR IP address
- Enter NVR text port (see next step)
Make sure to save the settings.
3. NVR setup
- Make sure the camera has been added to the NVR and live/playback video is accessible.
- Make sure the time settings are correct and correspond to the same settings as the NVR (time zone, daylight savings, etc.) It is recommended to enable the NTP server on the NVR and have the camera sync the clock with NTP.
- From the NVR setup menu, navigate to the Device > Text menu.
- Select the camera and define the port settings as listed below:
Note: The camera port settings must match with what you have defined on the Road AI > NVR setup.
Device name: This can be any name that you would like to choose.
Channel: This needs to be the correct NVR channel that you have added the Road AI LPR camera as.
Port: This needs to be the same as you have defined in the Road AI > NVR settings. Make sure the ports are within the defined port numbers allowed at the in the NVR (1024 – 65535). By default the NVR starts with port 7001. Each entry and camera must have a unique port setting.
Encoding: US-ASCII
Device type: Select User Defined.
Start and End: Enter the values as shown below:
Make sure to save the settings by clicking the OK button on the popup AND the Apply button at bottom of the TEXT setup menu.
How to search for LPR events
1. Define the time and date as you wish you search for events.
2. At the defined search, you notice the events as shown below.
Click on any events to see the video clip with the details of the vehicle identified.
Troubleshooting tips
a) If you are not getting any LPR events make sure your camera is connected to the network and that the NVR can receive video as well as camera-based events such as motion or simple line-crossing events. You may need to create and enable an event rule in the NVR.
b) If you are on a network with a firewall and router, your ports could be blocked. Run network diagnostics to make sure the IP address and ports defined are not blocked.
c) Check the time and date, time zone and daylight savings time settings for the camera and NVR. It is recommended to use NTP to sync the camera's clock to the NVR.
d) If you still don’t see any LPR events coming in to the NVR search, open the Road AI app web interface from a browser. Under the events page, make sure the plates are read and able to populate in the camera interface.
