Door Viewers (Judas): Practical Security for Every Door

Door viewers, often called "judas" or peepholes, provide a quick and secure way to see who is outside without opening the door. They are a simple but effective security upgrade for flats, houses and communal entrance doors.

Choosing the right door viewer

Opt for wide-angle viewers to give a broader field of vision and choose models with adjustable viewing angles for different door thicknesses. Digital viewers can display a clearer image and are helpful for mobility-impaired users who cannot reach a conventional peephole.

Features to consider

• Wide-angle optics for improved visibility.
• Adjustable length to suit various door thicknesses.
• Privacy covers to prevent reverse viewing.
• Digital options with screen and recording for added security.
• Simple screw-in installation with minimal tools required.

Door viewers offer a low-cost security enhancement that is quick to fit. For communal or high-rise properties, check building regulations and consider complementary measures such as chain guards or intercoms. Look out for bargains on standard models when replacing multiple units.
