Chrome can be problematic. Have you tried another browser like Firefox? Maybe not the easiest, but VLC media player will normally stream almost anything.
Your NVR is going to need dewarping capabilities. The dewarped images from the camera GUI are very useful as you have discovered. True dewarping capabilities would allow you to "zoom" into any portion of the picture clearly.
Just for fun, you should download a copy of Digital Watchdog Spectrum...
I've used it with Genetec's Security Center where the "tracking" video appears in it's own stream. Try sending a help desk request to Axis tech support and see if they can provide a rtsp url for that tracking stream. You might have to create a free Axis account to submit a help desk request...
99% of our Axis PTZ failures are due to a defective POE power supply circuit in the camera. Since there aren't any service manuals or schematics available for Axis PTZ cameras, it's hard to determine where the failure is. But I'm betting that it is a very common failure between all PTZ models...
I'm wondering if it's due to some kind of mis-alignment in the optics of the zoom lens?
If you don't already have an account with Axis, you can sign up for free then submit a case to their Help Desk. Response may take a day or two but they usually have a solution.
Mainly depends on what kind of mounting surface your trying to fasten to. There are so many variables that Axis can't reliably recommend a fastener.
This camera is somewhat front heavy but I've never had one fall off a wall.
What are you mounting to?
Clones?? Maybe something didn't translate right? Cloning physically like in 3D printing? Not sure I understand?
If your looking to scan a network looking for all Axis cameras, Axis.com has a free utility call IP Utility that will do that.
Log into your camera's user interface and click Setup / System Options / Maintenance. Under Upgrade Server click Choose File and browse to the location where you downloaded the latest firmware from Axis.com then click Upgrade.
Go to axis.com and look under Support, get latest firmware. You might not have to register to download firmware now. In the past, you had to register with Axis to download but it appears currently that might not be the case. Downloading firmware is free either way.
I've installed hundreds of Axis cameras to static settings and never seen one revert back to DHCP. This is what I assume you mean when the camera reverts to 192.168.0.90
Are you using a reliable source of POE? A POE switch or individual power inserters? I suppose flaky power could cause this...
