Hi and thanks for the promp reply. I connecting directly (126.96.36.199/64 and also tried 192.168.1.128/64) using SADP. I wonder it takes about 4-5 minutes to boot. Some notes which may help identify problem. - TFTP update log was not as described in docs. It finished on digicap.dav transfer complete. But did not show any kernel updated, etc messages. - Camera never become Inactive, but always appears online as Activated. - Previuosly (5.2.5) it was configured as DHCP but now I see settings reset to default values. But passwords not working. May be somebody can provide link to 5.2.5 fw? I will try to restore via TFTP again. Also, I think the factory reset method with (RST 30s lock + Power ON) should work with SD card. But I am not sure where to get recovery image.
