Depth of Field and Angle Width on Indoor Security Camera

I have a Ring Subscription Plan for just a Video Doorbell, which is ideal for me and works very well, especially as I am often away from home. I also have an electricity meter in a very inaccessible place and it occurred to me that I could read it remotely with a Ring indoor camera. The camera would need to be located close to the meter and thus the camera would have to a depth of field that would give a picture that is sharp enough to see the individual numerals. I can't find any information on the Ring website on depth of field or field of view. Can anybody help?
