DW Spectrum Integration

We have two approaches to integrate ALPR with Digital Watchdog Spectrum:

Approach #1

Stream On Premise.  Run Stream on-premise and forward ALPR results straight into DW Spectrum.

Result: Search and view vehicle plates and video footage inside DW Spectrum. Manage site with ParkPow.

Approach #2

Stream Cloud.  DW Spectrum alerts Plate Recognizer of motion events.  We then grab a short video clip to analyze for ALPR. 

Result: See bookmark of plates inside DW Spectrum.  Manage site with ParkPow.

Plate-Recognizer-DW Spectrum Integration Approach1b
Plate Recognizer DW Spectrum Integration Approach 2

Approach #1: Stream to DW Spectrum

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

Then, run our Stream – DW Spectrum integration software to forward Stream Webhook Events to DW Spectrum as Alerts.

With our Stream-DW integration, you can send Stream detection events to your DW server via a webhook.

This way, a bookmark with detection information is saved on the DW timeline.

Later, you can search for the detections and locate the timeline where the detection occurred, view, or download the detection video.

Now, you can skip to Step 3.1 below to forward ALPR results over to ParkPow.
