First camera install, $1000 budget

[Jimmy Forester]

I don't own an NVR but would hazard a guess that you can adjust the focal length from the NVR. I use Pale Moon, 32 bit version, browser and access the camera directly for setup purposes. The 32 bit version of Pale Moon allows the "plug ins" needed that are being blocked in newer, 64 bit, browsers.

But this would be adjusted through some kind of software rather than having to open them up and adjust them?

What NVR are you using?
No, you don't have open them up to adjust them.
You should be able to adjust them while viewing one cam in the NVR. Try right clicking on the live picture and see if that brings up another menu.

Or, you will need to access the camera directly using Pale Moon and the adjustments are there during the live view of the cam.
