PartⅠHTTP Notification between Network Optix and Milesight VCA
1. What is Milesight VCA
VCA is short for Video Content Analysis. Milesight VCA provides advanced, accurate smart video analysis for Milesight network cameras. It enhances the performance of network cameras through 8 detection modes which are divided into basic function and advanced function, enabling the comprehensive surveillance function and quicker response of cameras to different monitoring scenes. There are 8 detection modes of Milesight VCA as follow.
Milesight VCA can work with some third-party VMS like Network Optix by using the HTTP Notification. But how to do the settings? Here we will take Region Entrance as an example.
2. How to set up the HTTP Notification between Network Optix and Milesight VCA
Step 1: Adding Milesight Camera in Nx Witness.
Step 2: Open Nx Witness Server Web Client, click the tag “For Developers” after logging into Web Client and then open “API Testing Tools(new)”.
Search “CreateEvent” to quickly find the API we want.
Step 3: The tool will automatically form Requesting URL after you fill in the content. We use three of these commonly used parameters. Fill in the information you want to send to Nx Witness when the Region Entrance is triggered.
Copy the Requesting URL.
Step 4: Open web page of the camera. Enable HTTP Notification in Alarm Action. Select Get in HTTP Method and choose one of the three URLs to enable. Set Trigger Interval from 0s to 900s. Paste the URL you just copied from API test tool in Nx Witness Server Web Client.
Reform the URL:
Note: Do not forget to finish User Name and Password (Nx Witness Server’s User Name and Password) and click Save.
Result: Once Region Entrance is triggered, Nx Witness will show the Notification.

You can set up to 4 ROI areas by drawing the screen. If you choose Normal Mode, it supports configuring the LPR detection regions for the current area. If you choose Advanced Mode(Only for PTZ series), it supports configuring different LPR detection regions for different PTZ presets (Only support Preset 1~4 so far).
Step2: Schedule Settings. You can draw the schedule by clicking“Edit”button. And then click “Save” or “Reset” after finishing setting. You also can copy the settings to other channels.
