well, despite thinking i read everything and did this correctly, looks like I may have bricked my Annke FDC600.
starting with Annke FW: v5.7.10 build 230110
uploaded HIK v 5.7.11 for what appeared to be the same camera (DS-2CD2366G2P-ISU/SL )
Nothing after the reboot.
Assume I'm dead in the water?
EDIT: maybe i'm rushing this? Showed up in SADP tool after about 10 minutes, but with no IP address. When I started to try to modify the network properties, it disappeared. I found it in my router dashboard, but with an IP that starts with 169, vs. 192. And I can't seem to enable DHCP in SADP before it disappears again or times out.
EDIT2:
OK... the factory reset thing i missed. I have now done that about 10x. It shows up in my router table, but has a conflicting IP with another HIK camera (that i've reserved that IP for already).
Then it will suddenly reappear in SACD, and also have conflicting IP. I try to activate (asks me for new password)... then when i hit "activate" just times out. Then it disappears from SACD again.
