Properties

HikCentral Setup

Enable Generic Events

Lumeo HikCentral Integration uses Generic Events to send Events to HikCentral. To enable them:

1. Launch the HikCentral Web Client, and navigate to Event and Alarm -> Custom Event -> Generic Event -> Receive Generic Event. Check Receive via HTTPS and Save.

2. Open HikCentral Service Manager and click System Management Services to confirm the Generic Event Receiving Port (HTTPS).

3. Use the "Generic Event Receiving Port (HTTPS)" value to setup your node properties in Lumeo.

Automatic Event and Alarm Configuration

1. Enable HikCentral OpenAPI following the instructions here: HikCentral Import.

2. Enable the Configure HikCentral option in this node's settings. Doing so will cause the node to configure:

• Generic Event Rules for each Generic Event that the node sends to HikCentral.
• Alarm Rules with default settings for each Generic Event Rule created in HikCentral.

Lumeo will create these Rules the first time the specific Event occurs. You can check a deployment's Events log in Lumeo to verify that they were created. Once created, they will be visible in Generic Event settings and Alarm settings within HikCentral.

Important

In order for Lumeo to create the appropriate Alarm Rule, the stream name in Lumeo must follow this naming convention: <AreaName1>/<AreaName2..>/<CameraName>. For example, if your Camera in HikCentral is in the following Area hierarchy, HikCentral Professional -> Office Location1 -> Foyer, the camera should be named as Office Location1/Foyer/Camera Name in Lumeo. If you import Cameras into Lumeo from HikCentral using the Lumeo Gateway web interface or the script helper, it automatically takes care of this for you.

Manual Configuration

If you do not have access to HikCentral OpenAPI, you will need to setup Generic Events and Alarms manually in HikCentral.

Manual Generic Event Configuration

Create a new Generic Event in HikCentral (from the Event and Alarm -> Custom Event -> Generic Event page) with the following settings:

• Transport Type: HTTPS
• Match Type: Search
• Expression: You can use any combination of terms that appear in the Metadata sent by Lumeo (format below).

Lumeo will send the following metadata in the Generic Event to HikCentral. This can be used to create a filter and configure the Generic event.

{
  "Request": {
      "Source": "Lumeo - <Source Name>",
      "Title": "<Event Name>",
      "Describe": "<Event Description>"
  }
}

• SourceName : This is the source name as configured in the Lumeo source. Ex. Office/Front/Foyer Camera
• Event Name : This is the Event name (custom or from upstream event nodes). Ex. Fall detected
• Event Description : This is the Event description, if provided by an upstream event node.

Manual Alarm Configuration

This Generic Event can then be used to trigger an Alarm or take other actions (such as recording video, sending alerts, messages, etc).

Navigate to Event and Alarm -> Event and Alarm Configuration -> Normal Event and Alarm.
