**6.1 Observe: a better detection**

"Seeing without being seen" is essential in military operations, and remains a common adage. Technology is helping, with the extended distances made possible by long-range cameras and their deportation to robotic systems. It can now also help to overcome several natural detection constraints such as night, fog or walls.

Moreover, digitised systems can operate 24 hours a day with great consistency, where humans are subject to fatigue and inattention, avoiding the risk of missing information.

For surveillance or patrol missions, where human resources are often lacking, the leader can delegate to systems the analysis of images of the area for the detection of movements and the potential presence of enemies. It should be noted that this detection should filter out false alarms as much as possible, such as the movement of leaves in the trees when the wind picks up.
