Integrating Thermal Cores into PTZ Systems: Motorized Zoom vs. Fixed Lenses
13. 8. 2025In today’s world, where both civilian and military areas are increasingly threatened by drone intrusions, having an effective and reliable early detection system is crucial. Traditional technologies like radar or optical cameras often fail in certain scenarios—and that’s where LWIR (Long-Wave InfraRed) thermal imaging, particularly uncooled microbolometer thermal cores, comes into play. Let’s explore why these modules are critical for anti-UAV systems.
What Is an LWIR Thermal Core (Uncooled Thermal Core)?
An LWIR thermal core is a module based on uncooled LWIR technology (spectral range approx. 8–14 μm), using a microbolometric detector that does not require complex cooling systems. This makes thermal cores compact, energy-efficient, and quick to deploy—offering significantly greater flexibility compared to cooled systems.
Advantages of LWIR Modules Over Radar and Optical Systems
-
Independent of Light Conditions: LWIR cameras operate in total darkness, fog, smoke, or dust—unlike optical systems, which rely heavily on visible light.
-
Thermal Signature Detection: Drones emit heat from motors and electronics. LWIR modules can detect this thermal contrast against the background—something radar often misses at low altitudes.
-
Low Thermal Noise and High Sensitivity: For example, the WEOM module provides < 30 mK sensitivity and 640 × 480 px resolution, delivering detailed imagery even with minimal temperature differences.
-
Low Operating Costs and High Durability: With no need for active cooling, these modules are lightweight and compact—ideal for both mobile and stationary defense systems.
Integrating LWIR Modules into Anti-UAV Systems
LWIR modules can be seamlessly integrated into existing surveillance and defense infrastructures. The WEOM ONVIF module supports direct IP streaming via Ethernet, Power over Ethernet (PoE), RS‑485 for PTZ control, and the ONVIF protocol, making it ideal for integration with modern camera systems. With a modular design and multiple interface options—including USB, HDMI, CVBS, GigE, and ONVIF—WEOM modules fit easily into CCTV, PTZ, and embedded systems. Reliability is further ensured through built-in NUC correction, factory calibration, and thermal stabilization, delivering consistent and high-quality image output.
The Practical Value of LWIR Modules
-
Early Drone Detection: Real-time thermal imaging enables drone detection during critical phases of approach—especially effective when combined with visual analysis or machine learning.
-
Complementary Technology: Studies show that combining LWIR with visible-spectrum imaging, enhanced by AI, greatly improves detection accuracy and reduces false alarms.
-
Wide Range of Applications: From airport and border security to protecting critical infrastructure and VIP zones, LWIR modules provide round-the-clock monitoring, regardless of lighting conditions.
