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.

Thanks for the reply. I have the camera connected to a QSeee DVR and I'm controlling it through that. I also tried a Swann DVR with the same result. Yes, it goes into calibration mode after rebooting. It spins around and seems to pass its checks. The menu that comes up after reboot says the following: BLK-PTZ36XIR SN 488553802 ADDRESS 2 COM FORMAT 2400 .8.1 PROTOCOL AUTO FIRMWARE 3.12 HARDWARE 1.20 BUILD DATE 14 06 27 TILT SUCCESS PAN SUCCESS There is no protective film or anything else on the lens.

Does anyone have suggestions? I'm thinking of taking the camera completely apart completely to see if it could be a hardware problem with the lens. Beyond that, I'm at a loss. Thanks for any suggestion at all - even if it's to stop wasting my time and to throw the camera away.

Was there supposed to be an image attached? I don't see anything.
