I am using an 823a and have the same issue. If the object is more than 10 feet away, it tracks ok most times. Anything closer than 10 feet, it will never track a person moving at actual walking speed. It might trigger once but then the person is gone and the camera loses them. The camera needs to pan further in anticipation of the distance.

Vertical auto-track also doesn't always work when it should. I can't really figure it out. I am on the latest firmware that added vertical tracking, but sometimes it doesn't move up when it could have, and sometimes it seems I need to reboot the camera to get vertical tracking working at all.

And lastly, too often the auto-tracking seems to "lag" or get hung up on something. I've tested this quite a bit and at the end of the day, it's just not reliable enough. I'm not expecting the world from it, but you can't even really track a footpath leading to a door reliably with very minimal video noise. You will notice it stops tracking quite often and just loses the person when it really shouldn't. I have all the sensitivity settings on the most sensitive... maybe try making it a bit more sensitive.
