KJ has a turret, alarm and her own gun, so she can check 3 different lanes. Imagine Ascent Defence. Put KJ alarm on mid, turret watching a short and watch a site from garden.
Cypher if its needed can put 2 info wires and camera on different spots, so he is also can cover 3 different lanes
You can imagine again Ascent, wires mid+a short and put some camera watching A main.
If want to have more info on the map both KJ and Cypher can cover 3 different lanes.
Chamber, Sage, Deadlock can cover 2 lanes at the best. Wall/trip one area and check the other. Thats all the problem about them.
