3.5" Digital Door Peephole Viewer

Product Description

Upgrade your traditional door peephole with a 3.5" Digital Door Viewer that gives you a larger, clearer view of who's outside your door.

Featuring a 120° wide viewing angle, 3.5-inch color LCD display, one-button operation, and low-battery warning, this digital peephole provides a simple and practical security upgrade without complicated WiFi connections or smartphone apps.

3.5" Color LCD Display

Instead of looking through a tiny traditional peephole, simply press the button to see the area outside your door on the 3.5-inch color LCD screen.

• Screen Size: 3.5"

• Display Resolution: 480 × 320

• Viewing Angle: 120°

The larger screen is particularly convenient for children, seniors, and anyone who finds a conventional optical peephole difficult to use.

120° Wide Viewing Angle

The 120-degree viewing angle provides a wider view of the area directly outside your door, helping you check visitors before opening.

One-Button Operation

No complicated menus or smartphone setup.

Simply press the button to activate the display and check outside. After approximately 15 seconds without operation, the device automatically returns to standby mode to help conserve battery power.

Discreet Peephole Design

From outside, the unit maintains the appearance of a conventional door peephole rather than a large exterior security camera.

The compact exterior design keeps your entrance looking clean while providing a digital viewing screen inside your home.

Battery Powered - No WiFi Required

Powered by 4 standard AAA batteries, the viewer does not depend on your home's WiFi network or a rechargeable internal battery.

This also means the viewer can continue operating during a home internet or electrical outage as long as its AAA batteries have sufficient power.

Batteries are not included.

Low-Battery Alert

A built-in low-power warning helps remind you when it's time to replace the batteries.

Easy Peephole Replacement

Designed to replace a compatible traditional optical peephole with minimal modification.

Compatible door specifications:

• Door Thickness: 1.57–3.94 in (40–100 mm)

• Peephole Diameter: 0.55–1.10 in (14–28 mm)

Please measure your existing door and peephole opening before ordering.

Durable Construction

The exterior unit features zinc alloy construction, while the reinforced mounting design helps keep the peephole and indoor display securely positioned.
