RLC-811A vs RLC-842a - aspect ratio and field of view

[user_680523663470834_680523663470834]

Hi
I got a reolink nvr and i need to buy another camera. Unfortunately I could not find an 4k poe camera with 2.8mm lens so I decided to buy a camera with optical zoom.
I am deciding to get a RLC-811A or RLC-842A.

Both 4k resolution and reolink support website says both have 16:9 aspect Ratio but when I check the field of view specs of both cameras I get confused. When I check the specs looks like the RLC-842A should have 4:3 aspect ratio as the proportion between H and V angles of view are not as big as on the RLC-811A.

Please could you just confirm the aspect ratio and angle of view are correct in the website?

RLC-811A - Field of View - Horizontal: 105°- 31° Vertical: 55°- 17°
RLC-842A - Field of View - Horizontal: 96°-27° - Vertical: 69°-21°

Also the camera RLC-542WA ( 5mp camera ) has 4:3 aspect ratio and same angle of view as RLC-842A ( Field of View Horizontal: 27°-96° Vertical: 21°-69°).

Ps. All specs information was taken from reolink website.

I would appreciate having an answer by tomorrow as the offer for the cameras will finish on Wednesday.

cheers
