Door Viewers

Our door viewers, also known as spyholes or peepholes, let you see callers before opening the door. Choose from wide-angle glass, crystal and plastic lens designs, including viewers offering up to a 200° field of view.

We also stock intumescent door viewers for fire doors and extension sleeves for thicker doors. Explore our door guards and wider home security range to complete your door security.

Door Viewer Buying Guide

What angle of vision do I need?

A wider angle, such as 180° or 200°, gives a fuller view of your doorstep. Glass lenses generally offer a clearer image than plastic.

Will it fit my door thickness?

Each viewer suits a specific range of door thicknesses. Check the stated range before ordering, and use an extension sleeve where required.

Can I fit a viewer to a fire door?

Fire doors require a viewer with an intumescent liner designed to maintain the door's integrity in heat. Choose a fire-rated viewer suitable for your door.
