Head to the restricted compound then hack the cameras until you profile the target. Once tagged, you can work your way around the guards and eliminate them silently until you reach the target. Alternatively, if you have a sniper rifle, you can take out the guards from a distance, outside the restricted area. This will put them to alert but they won't be able to find you as long as you're at a good distance away from them.
