Iron Door Peephole and Video Intercom Cutout Placement Guide

t414-28

Place the peephole at a comfortable eye level for the people who use the door most, usually near the middle height of the leaf, and set the video intercom panel at a reach height that is easy to see and press. Plan both cutouts on the drawing before production, because the position affects the internal reinforcement, the lock side and the finish.

Why cutout placement matters before production

A peephole and a video intercom panel are small openings, but in a steel or aluminum door they change how the leaf is built. The factory needs to know the exact positions early so the frame can be reinforced around the openings and the wiring can route cleanly inside the door.

Cutting after the door is finished is possible in some cases, but it can weaken the structure, damage the finish and leave an uneven edge. Deciding the layout at the drawing stage avoids these problems.

Choosing the peephole height

The peephole should sit at eye level for the adults who will look through it most often. For most households this is near the middle of the door, but if children or a person in a wheelchair use the entrance, consider a second opening or a lower position.

Measure the height from the finished floor to the centre of the lens.
Keep it clear of the lock, handle and any decorative bars.
Confirm the glass or lens angle suits the depth of the door.

Positioning the video intercom cutout

The intercom panel usually goes on the outside of the door or on the frame beside it, at a height that lets a visitor reach the call button and see the camera clearly. Work from the manufacturer's mounting height for the unit you have chosen, not from a general guess.

Leave space for the cable run and any junction box. Keep the panel away from the hinge side so the leaf can open and close without catching the wires.

Spacing from locks, bars and edges

Both openings need clear space from the lock body, deadbolt, handle and the door edges. Cutting too close to a lock can leave the steel thin and make the door less stable. Too close to the edge can cause the panel to deform over time.

Discuss the spacing with the fabricator when the drawing is prepared. Decorative iron bars or perforated panels may also need adjusting so that the openings align cleanly with the pattern.

Wiring and electrical planning

If the intercom is wired rather than wireless, plan the cable route before the door is finished. Conduit or a protected channel inside the leaf keeps the wire safe from the hinge and from moisture.

Confirm the cable path from the panel to the power and receiver.
Ask for a service loop so the panel can be removed for maintenance.
Have a qualified electrician check the final connection.

Checking the layout on site and approving the drawing

Before production, a technician should measure the actual doorway and mark the proposed positions on the door or on a template. Stand inside and outside the door to test sight lines and reach. Adjust the marks until both feel natural.

Once the drawing and written specification show the peephole and intercom positions, approve them in writing. This becomes the reference for cutting, reinforcing and finishing the door.

Frequently asked questions

What height is standard for a door peephole?

Most peepholes sit near average adult eye level, roughly in the middle of the door. The best height depends on who uses the door most, so measure for your household.

Can a peephole or intercom be added to a finished metal door?

Sometimes, but cutting a finished door can weaken the structure and damage the coating. It is better to plan the openings before production.

How far should the intercom be from the lock?

Keep the intercom clear of the lock body and handle with enough steel around the cutout to keep the door strong. Your fabricator can confirm the exact spacing for your door design.

Do I need an electrician for the intercom wiring?

Yes, the final electrical connection should be done by a qualified electrician. Planning the cable route in the door during fabrication makes that work much easier.

Common mistakes to avoid

Choosing the peephole and intercom height by guesswork and cutting the door without a checked layout. Leaving no route for the cable until the finish is already applied.

Our recommendation

Mark both positions on the door or a template at the site visit, test them from inside and outside, and approve the drawing before production starts. Ask for conduit and a service loop for any wired intercom.

Summary

Plan the peephole at comfortable eye level and the intercom at easy reach, with clear spacing from locks and edges and a cable route set before the door is made.
