Recently I loaded
openWRT onto a $21 TP-LINK
TL-WR703N. While
fine tuning the TL-WR703N I came across an interesting code module that can be loaded onto a TL-WR703N with attached camera that tracks motion. It occurred to me that this "motion" package might be applicable to IP-Cameras, as well. You can read about installing the "motion" package on the TL-WR703N
HERE, and about the motion package
HERE.
You can even turn the tl-wr703n into a camera using firmware packages found at the
Madox.net blog.
