I have an Alibi BLK-PTZ36XIR PTZ camera (https://www.supercircuits.com/media/docs/blk-ptz36xir-manual-br.pdf) which I believe is the same as the Hikvision DS-2AE7168N-A (https://us.hikvision.com/en/products/more-products/discontinued-products/analog-ptz-camera/ds-2ae7168n-ds-2ae7168n). Everything on the camera seems to work, but the focus. The picture is only in focus at a certain zoom level (around 10x). Anything wider or more zoomed is completely blurry. The fine tune zoom control changes the focus slightly and is only helpful if the camera is zoomed at ~10x already. I've changed all the settings I can find, reset things to default, etc. Manual focus, Auto-focu and Half-focus - nothing seems to work.
I can't find any updated firmware to try (and I'm not sure how to install it anyway since it's an analog camera).
Any ideas of things to try would be much appreciated. At this point the camera is fairly useless.
Thanks in advance.
