However, I don't know if this kind of rigor exists with the hacking rules. For instance, a common tactic is to hack a security camera, feed it to the party, and give them a view of what's going on. Great... but how is that interpreted mechanically? Do you limit it to better descriptions of the enemies (like "there are four more coming up the stairs, and you spot grenades on their belts!"), or do you grant the party +1 dice pool bonuses for all attacks, or -1 to enemy attacks because they no longer have that advantage, or what?
There are several things you could do, one is to consider having the video feed grants surprise and use the + 6 ambusher bonus on a surprise test. Another is to look at the AR bonus of +1 to +3 when equipped with extra AR information, see SR4 P. 208 sidebar. There's also the fact that the hacked camera can act as a feed for the groups tacsoft, which can also add to direct bonuses. Using these bonuses are a good tool for giving incentive to the team to hack the cameras. It can also explain why some of the NPC sec teams can be more effective when opposing the runners.
