HapSee Mate IPC "hack"
So, one of my small-inbetween-projects was to "hack" a 20€ IP camera which I bought on eBay. However it was not that easy as I destroyed the first UART connector by just wiring it wrongly ;). At least I've managed to create some kind of custom firmware which starts a sshd, a ftpd and disabled some, in my eyes, useless tools which are connecting wildly https://github.com/daill/h4ps33. Just copy the v2 hack onto a SD card and restart your camera but be aware, even it works for my two cameras you will do it on your own risk.
