Question about B&E characters vs magic security, Is it even possible ? Options

[Kirschkern]

Hi there

I recently started playing SR4 and decided do go for a character that can go in and out without being seen or having to shoot someone. Having played D&D for many many years I foolishly thought if there is a magic way to detect things, there must be a way to magicly fool these mechanism.
So I made a mystic adept. Probably not the best character for B&E as it turns out but it somewhat resembled my unseen seer (for those of you familiar with D&D 3.5) (IMG:style_emoticons/default/smile.gif) . And to make matters worse he has sustaining foci.

On the first job the target location was guarded by a simple watcher. As I understand these kind of spirits are dirt cheap and it seems most valueable targets will at least be guarded by one patroling the area.
How are B&E characters supposed to work when spirits as simple as watchers can see you no matter what ?
The FAQ only seems to be handling infiltration on the astral plane vs other astral beings.

So I need some help on the matter ! What can I do to hide from that sort of guards ?

• Does the infiltration skill work at all ?
• Do I need to be astral percieving ?
• Is there anything nuyen can buy to help me on the matter (drugs, armor ...)
• Any nondectect spell for this purpose ?
• Any Adeptpower for this purpose ?
• Does the conceal power from summoned spirits protect me from dectection ?

I would greatly appreciate any help on this character because if there is no way I don't really see a point in playing him :/
