The small, often circular, viewing device installed in a door to allow occupants to see who is on the other side without opening the door is commonly known as a peephole.

Also referred to as a door viewer or a spy hole, this simple yet effective security feature provides an added layer of protection for homeowners, allowing them to visually verify the identity of visitors before granting them access to their home.

The purpose of a peephole

A peephole, also known as a door viewer, is a small opening in a door that allows individuals inside to view the outside without opening the door. The primary purpose of a peephole is to enhance security by allowing occupants to see who is outside before opening the door. This simple device provides a safe and discreet way to identify visitors, delivery persons, or strangers without exposing oneself to potential threats. Peepholes are commonly found in residential and commercial buildings as a cost-effective and practical solution for home security.

3. Doorbell viewer: A peephole integrated with a digital camera and display screen, allowing for a clearer and larger image of the visitor.
4. Combination peephole: A peephole combined with a door knocker, doorbell, or security camera for added functionality.

1.	Choose the location for the peephole on the door, ideally at eye level.
2.	Mark the center of the door where you want to install the peephole.

Benefits of having a peephole

Having a peephole on your door provides added security by allowing you to see who is outside without opening the door.

Peepholes are especially helpful for children, elderly individuals, and those living alone, as they can safely assess visitors before deciding to open the door.

In addition to enhancing security, peepholes also offer convenience by eliminating the need to open the door for strangers or unwanted visitors.

Peepholes are relatively inexpensive and easy to install, making them a practical and effective security measure for any home or office.

By having a peephole, you can feel more secure and confident in your ability to control who enters your space, helping you to feel more comfortable and at ease in your own home.

How to use a peephole

1. Stand close to the door and position your eye right behind the peephole.

2. Look through the peephole to see who is on the other side of the door.

3. Make sure to keep both eyes open to have a wider range of vision.

4. If the peephole is too high or low for you, consider using a step stool or bending your knees slightly.

5. Do not make any noise while looking through the peephole to avoid alerting the person outside that you are checking on them.

6. If you are unsure about the identity of the person at the door, do not open it and consider calling the police or a neighbor for assistance.

Maintaining a peephole

Peepholes are essential security features that allow people to safely identify visitors before opening the door. To ensure that your peephole remains effective, it is important to regularly maintain and clean it. Here are some simple steps to maintain a peephole:

Step 1: Clean the peephole regularly with a soft, damp cloth to remove any dirt, dust, or smudges that may obstruct your view.

Step 2: Check the clarity of the peephole regularly by looking through it from both inside and outside of the door to ensure that there are no obstructions.

Step 3: If the peephole is loose or difficult to turn, tighten any screws or bolts that secure it to the door to ensure that it remains in place.

Step 4: Consider replacing the peephole if it is damaged, scratched, or cracked, as these imperfections can impair visibility.

Step 5: Test the functionality of the peephole regularly by having someone stand outside the door while you verify that you can see them clearly through the peephole.

Security considerations with peepholes

Peepholes are essential for enhancing security in a home or office as they allow occupants to safely identify visitors before opening the door.

When installing a peephole, ensure that it provides a wide viewing angle to see clearly both near and far from the door.

Regularly clean the peephole to ensure maximum visibility and prevent any obstruction that may compromise security.

Avoid disclosing information about the presence of a peephole to strangers or potential intruders, as it may alert them to your security measures.

Consider installing a digital peephole camera for added security, which allows you to view visitors on a digital screen from the comfort of your home.

If you notice any tampering or damage to the peephole, immediately replace it to maintain the security of your premises.

Always use caution when approaching the door and verify the identity of the visitor before opening it, even if you have a peephole installed.
