When the idea was not invented and the cameras were not that compatible and feature-packed, most people preferred to incorporate peepholes into their doors that allowed them a one-sided view. However, with the evolution of cameras, they have become a more comprehensive option for security. Features like 2-way audio, recording access in smartphones, and remote control provide a much more secure and convenient way to greet the visitors.
