Network Optix Integration

We have two approaches to integrate ALPR with Network Optix:

Stream to NX. Run Stream on-premise and forward ALPR results straight into NX. Watch 5 minute video.
NX to Plate Rec Cloud. NX alerts Plate Recognizer of motion events and creates a bookmark of the motion event. We then grab a short video clip to analyze for ALPR. Results are sent over to ParkPow Dashboard. Watch 7 minute video.

Approach #1: Stream to NX

See instructions on how to Install Stream on a Linux, Windows, Jetson or Raspberry Pi machine.

Then, run our Stream-NX integration software to forward Stream Webhook Events to Network Optix as Alerts.

Approach #2: NX to Plate Rec Cloud

Step 1.1. Sign up on Plate Recognizer.

Step 1.2. Click on your email address in the upper right hand corner and select Activate NX.

Step 1.3. On the Plate Recognizer Activate NX page, enter your NX Server username, password and Server URL.

Step 1.4. Enter the Country Code(s), such as us-fl for Florida or gb for the United Kingdom. Full Country Codes can be found here.

If your server is not directly accessible via the Internet, then proceed to Step 1.5. Otherwise, go to Step 2.1.

NOTE: Please do Steps 1.5-1.9 if your server is not directly accessible via the internet.

Step 1.5. Connect your server to the NX cloud then use the cloud proxy URL which is in this format:
[system id].relay.vmsproxy.com

Step 1.6. Check the next screenshot for where the system id is located. So like in this case the URL to use is (just an example):
de36beaa-d1c2-477d-bd8e-0c5f06e3afa3.relay.vmsproxy.com.

Step 1.7. Go to System Administration Settings. Right click to popup the menu.

The best way to view the ALPR results is on ParkPow! Our sister company, ParkPow provides a full ALPR Dashboard and Parking Management solution so you can:

Search vehicles by plate, timeframe, site, type, color, etc.
Enforce parking policies (e.g. 3 hour limit for guests).
Create custom alerts and get notified when specific vehicles (e.g. denied, visitor) arrive.
See and track full vehicle details with Vehicle CRM.
Easily integrate data from other systems.

You can optionally use webhooks to forward the ALPR results with your existing application or system.
