The Importance of Focal Length over MP in camera selection

[Ri22o]

For reference, here are my front door 5442s. Height is about 9.5'. One is above the front door, the other is about 11' away. They are both 3.6mm. It depends on the person and what they're doing as to whether I can get a good face capture or not.




I also have a 2.8mm next to the door, just above the doorbell. I have considered changing it out for a 3.6mm, but it hasn't been a strong consideration. I do need to work on some settings adjustments though. The seasons really make a difference with lighting and cloud cover.


I also just made this to tell people I am both not interested and to draw more attention to looking over that way.

That 2.8 needs some SSA or WDR.

That 2.8 needs some SSA or WDR.

I just checked SSA is on.

 

[bigredfish]

It may be turned ON, but I'll bet it shut itself OFF in that picture. Check this out

One downside to SSA, while it gives a much better image in scenes with big lighting differences, it can and will cut out even when turned on.
By definition its dynamic and decides for itself when its too bright for it to be enabled and "not needed"

No backlight


WDR


SSA



So SSA is On with my Day profile until about 7pm when my schedule switches to Night Profile.

Here's a shot at 2:40pm


Another at almost 4pm



No watch what happens when the sun is at max bright shining into the carport at about 4:30pm

Yep, I posted about the same issue some time ago. I may just need to add some WDR to it.

Is this normal behavior? I have noticed this happening out of the corner of my eye while I have the monitor on and working, but never really paid attention and looked into it. It is almost as if it shut the SSA off. I tried refreshing the settings in the UI and a reboot of the camera, but it persisted. The only thing that got it back to normal was switching from the Day profile to Night and back, and 5 minutes later it did the same thing and is now back to acting as if SSA is off.

Ahh yes now I remember.

I did have WB set to Auto again, I’ll experiment with that.

 

[Ri22o]

Compared to yesterday, this is now with SSA active.

 

[bigredfish]

Yep it does over do the saturation and under do the contrast. But the price to pay, like with WDR, for getting face shots in dark areas that are backlit

That would be correct on the camera.

And yeah, probably best to make a new thread (not now but any future questions) for specifics to your install.

New Thread here.
