All camera lenses have limitations on what they can simultaneously focus. Typically, it is a range like x feet to y feet. Objects within that space will have more detail and sharpness. Objects before and beyond that distance will be less legible. A car’s license tag, for example, might be ambiguous (Is that the number 8 or the letter B?).
While wide angle lenses have a larger focal distance, ultra-wide angle lenses like this camera has, introduce distortion that destroys focus on the peripheral.
