Problem: The live stream cuts out after 5 minutes.
Solution: The SDK requires a "Keep-Alive" packet. You need to implement a heartbeat thread that calls NET_EC_KeepAlive() every 30-60 seconds.
Assuming you have imported the Hikmicro .NET wrapper:
// Initialize device HikMicroCamera camera = new HikMicroCamera("USB_VID_1234");// Start thermal stream camera.StartThermalStream();
// Timer to check every 100ms Timer timer = new Timer(100); timer.Elapsed += (s, e) => var tempData = camera.GetCurrentTemperatureMatrix(); // 16-bit array
// Find the "Hot" max float max = tempData[0,0]; for(int x=0; x<width; x++) for(int y=0; y<height; y++) if(tempData[x,y] > max) max = tempData[x,y]; Console.WriteLine($"Current Hot Spot: max°C");
;
Companies using DJI or custom UAVs often integrate a Hikmicro thermal core (like the 1.0 or 2.0 core). The SDK allows the flight computer to overlay temperature data onto the telemetry (OSD).
The latest HIKMICRO SDKs are optimized for ARM architecture (Raspberry Pi, Jetson Nano). This is a hot trend because it allows developers to run local AI models (like YOLOv8) on the thermal feed without sending data to the cloud.
While HIKMICRO offers security cameras, the SDK allows security integrators to build specialized perimeter defense systems. By accessing the thermal stream, developers can write algorithms that ignore moving trees or swaying grass (low thermal signature) but trigger instant alerts for human or vehicle heat signatures (high thermal signature), significantly reducing false alarms compared to optical cameras.
Once you have the SDK streaming live temperature data, you can build:
HIKMICRO Device Network SDK is the primary tool for developers to integrate HIKMICRO thermal and optical hardware into third-party software. The "Hot" designation typically refers to Hot Spot Detection hikmicro sdk hot
(automatic tracking of the highest temperature in a frame) or Perimeter Protection HOT (intelligent human/vehicle detection for security). 🛠️ Key Capabilities
HIKMICRO provides cross-platform support for Windows, Linux, Android, and iOS to enable real-time thermal analysis. Real-Time Data Streaming: Output raw radiometric data or processed video streams via SDK, ISAPI, or Modbus Temperature Analysis: , Cold Spots, and Center Points automatically. Smart Alarms:
Trigger events based on temperature exceptions (e.g., fire prevention) or VCA rules (line crossing, intrusion). Image Fusion:
Combine optical and thermal channels (Bi-spectrum) to improve feature extraction and visual clarity. 💻 SDK Functions for "Hot" Features
Developers primarily use these function sets to manage thermal data: 1. Hot Spot Tracking Problem: The live stream cuts out after 5 minutes
The SDK can retrieve the coordinates and temperature of the hottest point in the field of view. Rapidly identify overheating components or fire hazards. Implementation:
Call the thermography configuration and data callback functions to receive NET_DVR_THERMOMETRY_UPLOAD structures. 2. Perimeter Protection (HOT)
This refers to Deep Learning-based analytics for high-accuracy security.
Line crossing, region entrance, and intrusion detection specifically optimized to ignore non-human heat sources. NET_DVR_SET_VCA_RULE_CFG command to define virtual boundaries and alarm triggers. 📥 Getting Started
