cellular home security system questions

["kyle" <cartesiankyle@xxxxxxxxx>]

Hi All,

I am in the research phase for a security system for a home I just
purchased.

Here are my concerns (maybe you can alleviate them?)
-Worried that phone line can be cut on traditional system
-Worried that any motion detector/etc that is wireless can be
"jammed"/"tricked"

With these concerns in mind, I am thinking about:

Laptop with an 8hour lithium battery (but it will be plugged in)
T-Mobile cellular internet connection (I have verizon wireless internet
for my work but it's pricey at $80/mo)
NextAlarm.com's ABN Broadband Adaptor
Some sort of home security system.. any suggestions? 2story
house,plenty of windows/doors (wired -unless there is no worry about
wireless vulnerabilities???)

Questions..

1) how will the ABN adapter plug into my laptop?
2) T-Mobile ceulluar internet runs at about 5-9KB/sec tops.. will this
be fast enough??
3) How does the entire connection stream work: central alarm unit ->
abn adapter -> (usb?) laptop -> t-mobile -> nextalarm.com
4) How hard is it to do the wired vrs wireless security yourself? I
would think like ten times harder at least?


Thanks for your time,


Kyle


ps- what do you think about "flex-o-glass" film to apply over the
windows?
