Once again I find myself siding with the fox.
Sorry Rotbart but while RAW states to use the rating as DP that just sucks at its porpouse at low rating, and barely mediocre with the top of the line; at rating 6 (for 3000

) is six dices, which most of time will grant something like 1-3 hits, but if we apply the dued modifiers (fog, crowds, camosuits, erratic movement of the camera, etc.) and/or uncooperative subjects that actively try to avoid detection (disguises, infiltration, palming) the effectiveness of the software goes down the tube.
I would say that the sensor/device rating of the camera (or whatever spits out the feed analyzed) + the software rating (which is capped by response) representes a nice way to handle the matter; you put up a surveillance system by pairing devices with softwares that controls the feeds so that you don't need to someone that checkes them, if you use RAW your making no difference of the hardware used (the wizest tech and the cheapest dreck work the same) and you are pitting 6 (probably less if the runners are competent) dices vs probably 12 (you know top of the line software should logicaly come to play when you hit the serious buisness, and when you hit that you think that corps use security system that a merely competent runner can defeat without much problem? after the second time you shot the smartass that came up with the idea and hire more spiders).
Seriously rating 6 software should be part of a rating 6 challange: something that should be face with serious skills, attributes and equipment, unless you want to entrust the life of the runners to the hands of fate (ergo you want dead runners).
OK I've rambled too much!
My point is RAW is rating alone, but I say device + rating and call it a houserule.
