Electro-Optical Sensors

DefenSync SkyDefender / Detection

Counter UAS Electro-Optical (EO) Sensors play a crucial role in identifying and tracking drones. By utilizing advanced electro-optical infrared thermal imaging (EO/IR) cameras, these sensors can accurately and reliably detect drones based on their visual and temperature-related characteristics. The seamless integration of EO sensors with other technologies acts as a validation tool, minimizing false detections, and ensuring precise and efficient drone identification.

EO sensors deliver high-resolution visual images, enabling security personnel to accurately identify drones. This visual evidence boosts detection accuracy, minimizes false alarms, and ensures an efficient and reliable response.

Independent of
Radio Signals

Unlike other detection technologies, EO sensors solely rely on visual sensors, eliminating the need for radio signals for detection. This makes them highly effective in a variety of environments, including daylight and indoor settings, where drones are commonly operated.

Integration with
Radio Signals

When integrated with radar systems and other detection technologies, EO sensors provide a comprehensive approach to drone detection. This integration allows for cross-verification of data, reducing false positives, and enhancing the overall effectiveness of the system.


Counter UAS EO Sensors consume low power and require minimal maintenance, making them a cost-effective choice for organizations with limited resources. This ensures that your organization's drone detection capabilities can be maintained in the long run without compromising effectiveness.

Key Features & Advantages

Counter UAS Electro-Optical Sensors offer several key advantages in drone detection, empowering organizations to proactively address the evolving drone threat landscape:

Electro-Optical Sensors – Challenges

While EO sensors offer valuable benefits, it's crucial to consider their limitations when making informed decisions regarding countering drone threats:

  • For optimal performance, EO sensors require a clear and direct line-of-sight to accurately detect drones. In densely populated or urban environments with obstacles, strategic placement of sensors is necessary to ensure maximum coverage and effectiveness of EO/IR detection solutions.

  • In certain situations, real-time human intervention may be required to determine whether the detected object is indeed a drone. This necessitates continuous staffing resources to ensure accurate identification and threat assessment using EO sensors.

  • EO sensors typically have limited detection ranges compared to radar systems. This limitation highlights the need for careful consideration and strategic placement of sensors to ensure adequate coverage, especially in larger areas or installations.
