Same issue. Initialization failure even though I can "see" camera.
Upgraded router to TP lInk Deco x55 pro mesh system (PINA!!). New gateway different from old gateway. New gateway is 192.168.68.1-Y. This was chosen by Deco mesh system. I could get all 4 other cameras back online without having to reinitialize them, but not my unreachable (under eaves of 2nd flood of the house on a walk-out basement side- +40 feet in air!), most expensive, IP PTZ Camera. Screen shots below.
Here's what I tried:
Removed all cameras from the NVR. Reboot. Add PTZ Camera. Reboot.
a-used NVR GUI to initialize -
b-(repeat reboot process) - used NVR Web interface (see below) to initialize: no love
c-(repeat reboot process) - direct connect PC with static IP of 10.1.1.100; using Edge browser and 10.1.1.70 was able to get onto login screen of camera. When I change password and hit "save" - nothing happens.
Note - when I try to initialize here's what's showing as camera settings:
IP address 10.1.1.70
Subnet Mask 255.255.255.0
Default Gateway 192.168.1.1
So I change these to:
IP adress 192.168.1.200
Subnet Mask 255.255.255.0
Default Gateway 192.168.1.1
and tried
IP address 192.168.68.200 (a confirmed open IP adress)
Subnet Mask 255.255.255.0
Default Gateway 192.168.68.1
Anyone have any ideas to get this camera back online without having to rent a bucket truck to do a manual reset?
