What feature allows the MQ-9 to be used for surveillance at night?

The MQ-9 is equipped with advanced infrared sensor capabilities, which are crucial for conducting surveillance at night. These sensors detect infrared radiation, allowing the drone to see and capture images in low-light conditions or complete darkness. Unlike standard cameras, which rely on visible light, infrared sensors can reveal heat signatures from objects, making them exceptionally useful for monitoring activities or detecting targets regardless of the time of day.

The functionality of the infrared sensors provides the MQ-9 with a significant tactical advantage, enabling it to perform reconnaissance missions under challenging conditions where traditional optical systems would fail. This capability is vital for military operations, where night-time surveillance can be crucial for planning and executing missions. Hence, this feature is what distinctly allows the MQ-9 to fulfill its surveillance roles effectively during nocturnal operations.
