Amcrest IP5M-T1179EW-28MM vs Dahua IPC-HDW5231R-ZE

I have both of these cameras. I couldn't pass up the Amazon deal for the Amcrest at $55 vs. $170 for the Dahua so I pulled the trigger on it. Overall, I have been pleased with it for my needs but the field of view seems to be seriously lacking. The Dahua and the Amcrest are located on either side of my garage looking out over the driveway and the Dahua has a much larger field of view. Do I have something wrong in the settings of the Amcrest? I have double checked and can't seem to find anything to zoom out or widen the field of view. The camera specs are similar so I'm surprised it looks this different.

Amcrest: 2.8mm lens, 103° viewing angle

Dahua IPC-HDW5231R-ZE: 2.7mm lens, angle of view H: 101°~31°, V:54°~17°

See attached images showing the field of views. I think this is pretty substantial. Am I missing something or did I do something wrong when setting up this camera?

Thanks!

Just a different native format.

"The Amcrest IP5M-T1179EW-28MM is a 5 megapixel IP camera with 4:3 ratio image resolution of 2592x1944..."

You can select some other formats in the setup but they'll be stretched.

So you're saying it's my eyes playing tricks on me? This is really 2° degree viewing angle greater than my Dahua?

The Amcrest is a 5MP on a 1/2.7" sensor with a fixed 2.8mm lens. The Dahua is a 2MP on a 1/2.8" sensor with a varifocal 2.7-13.5mm lens. Even if you set the Dahua to 2.8mm, the different sensor, MP count and lens mounting will give you a different FOV.
