Want to view everything from my blackberry

[Newbie007]

Newbie here......I'm looking to install 2 camera's inside my house. I'm not interest in sensors, or color video, but I would like audio and the ability to view everything from my blackberry when outside the home. What is the BEST system for these simple requirements? Also, do I need a dedicated PC/laptop for this? If I have only one laptop, and I take it with me, have I killed the network?  Thanks

Tough to say... exactly what you should do. Audio is a bigger requirement (in many ways) than video. You could look at IP cameras. At least they don't require a computer, just an InterWeb connection [router].
