In Escape from Tarkov, Skier can give you the quest Informed Means Armed, which requires you to plant three Wi-Fi Cameras at separate scouting locations in Woods, Customs, and Interchange. You must be at least Level 24 to access Informed Means Armed and it requires the purchase of at least three Wi-Fi Cameras.
The purchase of a Wi-Fi Camera in Escape From Tarkov is unlocked at Mechanic LL1. The Informed Means Armed quest is one of the tricker ones to complete, especially since the unique placement of the Wi-Fi Cameras requires you to maneuver around a little to plant them very specifically.
