Replace a broken camera, with same model - How to setup

[Tech.desk]

New job, and I could use some help.
My predecessor ordered a DS-KH8350-WTE1 to replace our current door bell camera that lost sound. It arrived after he left now I need to replace the unit. Since I know little about the system, I want to set up the replacement with the same ip address, username, password, etc. as the current one.
How do I do this?
I can see the video(Live View) on my iPhone app, and NVR; however, I cannot access the camera directly through the browser by entering its ip address. I get an error '
This site can’t be reached
xx.xx.xx.xx refused to connect.

1. From the NVR, I found the door bell camera's username and password but why is the camera refusing the browser connection? I think my computer is on the same ip range as existing camera's ip. We are using a 255.255.252.0 as the subnet so, x.x.0.0 should be the range. My computer has the first two numbers the same.
2. Is there an order in Activating the new and swapping the old device/camera? I think the default ip for the new camera is (192.0.0.65), so I might have to change my ip address of my machine to configure it then change it back

Any help would be greatly appreciated.

The wizzard on new indoorstation should guide you. It may be the problem if the password on door station is not the one you tried.

Protocol 2.0 states that in order to register new indoor station to door station, you have to register it via registration password. It may or may not be the same as admin password.

Under Device management of door station via web interface you should see indoor station on the list with green checkmark online status.
