Integrating a thermal core into a PTZ (Pan-Tilt-Zoom) camera system is a crucial step in developing an advanced visual solution for surveillance, inspection, or security applications. Choosing between motorized zoom and fixed optics isn’t a simple decision—each option has its own strengths and limitations. So, how do you make the right choice? And how does the thermal core itself influence that decision?
The Compact Heart of Every Solution: WEOM Thermal Core
At the core of any high-quality thermal imaging system lies the LWIR thermal core. The Workswell WEOM® represents a powerful yet compact solution that integrates easily into a wide range of systems. It offers a high resolution of 640 × 480 px, exceptional sensitivity below 30 mK, and a fast startup time of under 5 seconds. With standard output support (USB3, GigE, HDMI) and an open SDK, it’s ideal for integration into both drones and stationary security systems.
But the key question remains: should the core be paired with a motorized zoom or a fixed lens?
When You Need Flexibility: Motorized Zoom
For applications where conditions change frequently and the camera must adapt to varying distances or scene details, motorized zoom is the clear choice. The Workswell WEOM Zoom Block features a 3× optical zoom (35–105 mm), allowing users to detect details at distances over 3 kilometers—without needing manual lens adjustments.
This setup is particularly effective in PTZ systems, where rotation and tilt are essential, but dynamic zoom capabilities are equally critical. A motorized zoom enables operators to seamlessly switch between a wide field of view for situational awareness and a narrow field for detailed inspection—making it invaluable for both security and industrial monitoring.
Simplicity and Reliability: Fixed Optics
On the other end of the spectrum, fixed focal length lenses offer mechanical simplicity and high reliability. They’re ideal for applications where the camera focuses on a specific zone, such as monitoring a perimeter, entry point, or critical infrastructure.
The Workswell WEOM ONVIF Thermal Module supports a wide range of fixed lenses, from 7.5 mm to 73.1 mm, covering fields of view from 91° to a narrow 8°. For example, a 73.1 mm lens is well-suited for detecting targets at distances beyond 500 meters.
Advantages of fixed lenses include greater durability, no moving parts, and lower power consumption. Combined with ONVIF support, these modules integrate seamlessly with standard VMS systems and are quick to deploy.
When to Choose Which?
The choice between motorized zoom and fixed optics depends entirely on the application. If your system demands adaptability, flexibility, and real-time responsiveness, a motorized zoom solution is the optimal choice. On the other hand, if your priority is continuous monitoring of a specific area, system durability, and minimal mechanical complexity, then fixed optics will provide the most efficient solution.
Conclusion
Integrating a thermal core into a PTZ system is more than just a technical decision—it’s a strategic one. Whether using motorized zoom or fixed optics, it's essential to choose a core that offers high image quality, low weight, and easy integration. The WEOM® module from Workswell delivers exactly that: a balanced combination of performance, modularity, and compatibility.
Whether you're securing borders, monitoring infrastructure, or developing a smart drone system, selecting the right optics and a reliable thermal core can make the difference between an average solution and an outstanding one.
