In the process of selling my house and I was trying to change the passwords on my ip cameras to something I could give the buyers. Even though I changed the PW on the IPC-HDW2231R-ZS, every time I cycled the power I ran into problems. I tried to do a factory reset from one of the config programs and then I ended up totally screwed. Now I cannot access it from the network at all. If I try to use the Dahua tool to change it to DHCP, it gives me a PW error. Is there some way to do a factory reset and start over? Thanks
