Dahua DHI-TPC-SD5441 4MP IR Thermal Hybrid Speed Dome Camera
The Dahua DHI-TPC-SD5441-B50Z45-DC-S24 is a high-performance thermal hybrid speed dome camera designed for advanced perimeter protection, long-range detection, and critical infrastructure monitoring. Combining a thermal imaging sensor with a 4MP visible-light PTZ camera, this dual-spectrum solution delivers accurate detection, recognition, and tracking of people, vehicles, and potential threats in complete darkness, adverse weather conditions, and challenging environments. Featuring intelligent AI-powered analytics, thermal fire detection, and powerful PTZ functionality, the camera is ideally suited for industrial facilities, utilities, airports, ports, correctional facilities, and perimeter security applications.
Thermal Imaging Benefits
The integrated thermal imaging sensor detects heat signatures rather than visible light, enabling reliable monitoring in:
- Complete darkness
- Fog and haze
- Smoke-filled environments
- Light rain and adverse weather conditions
- Large perimeter installations
This allows the camera to identify potential threats that may not be visible to conventional CCTV systems.
AI and Intelligent Analytics
Advanced AI functions include:
- Intrusion detection
- Tripwire protection
- Human and vehicle classification
- Smart tracking
- Thermal fire detection
- Early warning alerts
- Behaviour analysis
- Intelligent event filtering
These capabilities help minimise false alarms while improving detection accuracy.
Features:
- Dual-spectrum thermal and visible-light surveillance
- Uncooled VOx thermal imaging sensor
- 4MP visible-light PTZ camera
- 45x optical zoom PTZ module
- 50mm thermal lens
- Intelligent perimeter protection
- Thermal fire and smoke detection
- AI-powered human and vehicle classification
