DIY steps
- Before starting, ensure the power is off and put on safety goggles and a dust mask. Verify the door peephole is compatible with your door type and thickness. Measure the door thickness to determine the correct installation method.
- Mark the center point of the door where you want to install the peephole, about 54-60 inches from the floor. Use a level to ensure the mark is straight. Double-check the measurement to avoid errors.
- Drill a pilot hole using a small drill bit, about 1/16 inch in diameter. Gradually increase the drill bit size until you reach the recommended size for your peephole. Be cautious not to damage the surrounding door material.
- Insert the peephole from the outside of the door, making sure it's centered and secure. Tighten the screws firmly, but avoid overtightening, which can damage the door or peephole.
- Verify the peephole is working correctly by looking through it from both sides. Check for any light leaks or obstructions. Make any necessary adjustments to the peephole or surrounding area.
- Clean up any debris or dust from the drilling process. Remove safety goggles and dust mask. Dispose of any packaging materials from the peephole.
