What would be an ideal framerate, image size and compression for my
requirements to get the face of the intruders clearly. Yes I want to
set it up only on motion detection. The max upload comcast offers is
from 384 to 768 Kbps for 4Mbps to 8Mbps download packages. Assuming the
worst case, is 384 Kbps upload bandwidth enough to transmit two IP
cameras to download on my brothers end which is anywhere from 768kbps
to 1Mbps download speed and that should be enough I guess.

Thats fine. I have a personal laptop with 100GB storage with Intel Core
duo processor and 1GB RAM and another unused desktop in my brother
place to record the video feed on his side.

IP cameras are a requirement since I want to record it in my brothers
place also. So then CCTV is not an option I guess.

I wish I can do that, but unfortunately I cant at this time :-((
