The recon program is a script made by AnKor85. It uses objects placed in the mission.
You already have the files in your Data/swf/external media folder. All you need to do is open any war grounds mission and copy the recon components and paste them into your mission. A War grounds mission has both types of recons, a single point and an area that needs to be covered.

This is the list of parameters
The structure of object name is
!PR - PR stands for Photo Recon, this is just to make sure that this is a marker object.
E00 - target number from 00 to 15. Corresponds to event number triggered by Media MCU upon successful sortie. There can be more than one marker for the same area.
Now, there is two options:
-A immediately after the number means that this is a waypoint for line patrol. Letters 'A', 'B', 'C', and so on define the order of waypoints. The order doesn't mean that player has to follow it, it just defines how an imaginary line between waypoints is drawn.
Otherwise, if there's no suffix after the number, the marker is considered to be a standalone circular area.
In my example I created a line patrol with 3 waypoints: E00-A, E00-B, E00-C.
And a circular area around factory as "E01"
r8 defines a radius of the recon circle (or half-width for recon line if there are waypoints). The number is hundreds of meters, i.e. 8 means 800m radius.
Then there are two mutually exculsive modes:
80% - coverage requirement for successful sortie. Once 80% of the area is photographed the counter will show "Completed!" and player can land.
x5 - requirement for number of photos. This is simpler mode when no coverage is calculated and even completely overlapping or barely covering the target photos are counted. In my example I used it for factory target where player has to make 5 photos of the factory.
Finally, a radius and a requirement only have to be specified in one marker for an area.
For example, full names for a line recon markers triggering event #00 with 3 waypoints, width of 1000m (i.e half-width=500m), and requiring to cover 75% of its area will be:
!PR E00-A r5 75%
