# Door Viewers: Enhancing Home Security
A door viewer, also known as a peephole, is a simple yet effective security device installed on doors to allow occupants to see outside without opening the door. Commonly used in homes, apartments, and hotel rooms, door viewers provide a safe way to identify visitors before granting access.
## How Door Viewers Work
Most door viewers consist of a small lens mounted on the exterior side and a viewing lens on the inside. Modern versions offer wide-angle or fisheye lenses for a broader field of vision, while some advanced models include digital peepholes with video recording capabilities.
## Benefits
– Safety – Verify visitors without unlocking the door.
– Privacy – Observe outside activity discreetly.
– Convenience – No need to open the door for unwanted solicitors.
## Choosing the Right Door Viewer
When selecting a door viewer, consider:
– Viewing angle (180° or wider for better visibility).
– Installation type (surface-mounted or drilled).
– Additional features (night vision, digital screens).
For enhanced security, homeowners can opt for smart peepholes that connect to smartphones, allowing remote viewing.
A door viewer is a small investment that significantly improves home safety, providing peace of mind by keeping unwanted visitors at bay.
