Here was what I mean by weird focus...That is awesome!
Hope the stickers do the trick, I don't want to have to park my car at that spot every night to focus the cameraYeah, but you got the plate with the budget cam at night!
The focus at that zoom will be more sensitive, but it is weird how they did that all on the same pole. I am guessing the reflective qualities are causing depth perception issues.
Dark enough... Here's the auto focus. I can use a onvif script to zoom in (its at max zoom so won't actually zoom more) periodically to force it to re autofocus. Waiting for a car to pass by to check result.... Can't test with my own car until the kids are all to bedYep, that has been one of the big problems with PTZ cameras for LPR and not able to force a focus like we can a fixed cam.
Right before the car enter the frame, the headlight actually caused the camera to re autofocus, but it very quickly lock on to the stickers again before the car enter the frameThat is incredible! Congrats!
It will be interesting to see if it is repeatable tomorrow and with differing weather events.
The ptz won't even focus on the tape?That is great. I could get my fixed cam to focus on the reflective tape, but the PTZ struggled and was usually out of focus.
May have discover something interesting by accident. Focus bracketing to get good focus at night. One reflecting tape marker on the near side curb (stick with sticker.... driveway marker...) and another on the opposite side of the curb along the aim line.... when the camera try to focus it appears to try to do its best to focus on both the near marker and the far marker, resulting in a focus in the middle of the street where we actually wants it. This maybe an alternate to the putting reflecting tape down the middle of the pavement I saw in the other thread.Mine would be blurry and I would have to manual adjust it. But it was a reflective tape around a fire hydrant and not an up and down same plane like yours are, so I think the rounded part was causing different bounce backs and it struggled. My fixed cam had a telephone box nearby with reflective tape that was same plane. I have stakes like you shown, so I will go out and give that a try next to the hydrant.
I didn't spend much time trying to make it work, I was just playing around one night with the PTZ to see if I could make it work as many people have posted having trouble trying to make it work, so I wanted to see how difficult it was.
it is also cutting way down on the false MD alert from the camera re-autofocusing, I was getting alot of false MD spam last night and only 1 or 2 so far tonight (knock on wood)Interesting theory and probably some validity to it - and that does look like your cleanest capture yet!
