3001 Series Wide Angle 3MP Ring Doorbell Camera System Lens
Why do doorbell cameras choose wide-angle lenses?
The main reasons why doorbell cameras generally choose wide-angle lenses are:
Expand the monitoring range: The wide-angle lens can cover a wider field of view, giving you a more comprehensive view of what is happening at the door, such as
packages, visitors, or even the corner of the porch.
Capture more details: A wide-angle lens can capture more details, such as visitors’ facial expressions, clothing features, and items at the door.
Reduce blind spots: The wide-angle lens can reduce the blind spots in the porch, ensuring that there is no area that cannot be monitored.
Why not choose a telephoto lens?
The viewing angle is too narrow: The telephoto lens has a narrow viewing angle and can only see a small area in front of the door, making it easy to miss important
information.
Distance limitation: Telephoto lenses have higher distance requirements. If visitors are too far away from the door, they may not be able to capture the image clearly.
Summarize
For doorbell cameras, a wide-angle lens is a more suitable choice. It can provide more comprehensive monitoring, help you better understand the situation at the door
and improve home security.
