I wanted to do a quick compare of auto focus vs fixed and highlight depth of field. I was upgrading the bird feeder cams from a Escam Q900 and Amcrest IP3M-956 to a Reolink 5MP. I wanted to see if the auto focus RLC-511 or the static focus RLC-420-5MP would work better. While the bird feeder is the primary thing I want to monitor having coverage of the yard beyond is a definite plus. So I replaced the Escam with the 2 Reolink models and stuck some wet floor signs in the yard to get a better idea of focus / detail, randomly placed at 26, 32 and 45 feet. There is also a license plate one the fence just beyond the barn in the shadows but that turned out to be irrelevant for this test.

The Amcrest IP3M-956 was OK but was really too close to the feeder for good focus and too low rez for good detail of the yard. Plus being an outdoor dome it needed cleaning a lot.

Now compare that to the view from the RLC-511 that zoomed out all the way has almost the same view angle as the Amcrest.

Here is the same view from the RLC-420-5MP. It is running a 3.6 mm lens so it is not quites as wides as the others so you would expect it to be just a touch sharper.

Since I set these up for monitoring the feeder it is in the center of the field and close enough to cause the auto focus to focus on it. Not to mention get in close like this.
Though obviously I need to up the shutter speed. Unfortunately The Reolink cams only allow for changing the frames/second. So I'm putting this back on 30 fps from the 15 fps in the above shot. See the matching video here showing the auto focus recovery times after various amounts of zoom.
Amcrest and the similarly functional Dahua definitely have Reolink beat when it comes to exposure options. Note the Amcrest and Dahua interfaces are almost identical.
