Thermal Camera Data Acquisition for BPPTKG

This project provides a cloud-based data acquisition service for collecting thermal camera data from an IP camera in the BPPTKG network. Since a direct connection to the IP camera is not possible, data is acquired in the cloud and sent to a webhook in the BPPTKG network.

Features

• Connects to an Axis camera via WebSocket
• Uses Digest Authentication to obtain a session ID
• Subscribes to temperature detection events
• Sends acquired data to a webhook

Requirements

• Node.js (v16+ recommended)
• A publicly accessible webhook endpoint to receive data

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/bpptkg-thermal-acquisition.git
   cd bpptkg-thermal-acquisition

2. Install dependencies:

   npm install

3. Configure environment variables: Create a .env file and add the following:

   CAMERA_IP=your_camera_ip
   USERNAME=your_camera_username
   PASSWORD=your_camera_password
   CALLBACK_URL=https://your-webhook-endpoint.com

4. Run the application:

   npm start

How It Works

• The application fetches a session ID using Digest Authentication.
• A WebSocket connection is established with the Axis camera.
• Temperature detection events are received and forwarded to the webhook endpoint.

Webhook Payload

The application sends data to the webhook in the following format:

{
  "TemperatureUnit": "Celsius",
  "MaxTempPositionX": "100",
  "MaximumTemp": "75.2",
  "MinTempPositionY": "50",
  "AverageTemp": "70.5",
  "MinTempPositionX": "120",
  "MaxTempPositionY": "60",
  "AreaName": "Merapi_Site_1",
  "MinimumTemp": "68.1"
}
