About this item
The Cal-Royal ELDVBEL150 addresses all three at once. It's a 3.5-inch LCD digital door viewer with an integrated doorbell, a 160-degree camera, automatic night vision, and image storage for up to 100 captures. The screen mounts on the inside of the door at any height. The outside camera lens blocks reverse viewing. Whoever is at the door cannot tell whether anyone has looked at them.
It fits existing door bores from 1/2" to 1-1/8" diameter without modification and requires no external wiring. Battery powered with three AA batteries included, it installs in minutes on any door between 1-3/8" and 2-3/8" thick.

How the ELDVBEL150 Works
When a visitor presses the doorbell button on the outside camera unit, two things happen at once: a 4-cycle audible chime sounds inside, and a live video image of the area outside the door appears on the 3.5" LCD monitor. The image is stored automatically. You can view it immediately or retrieve it later from the 100-image internal storage, which creates a visual log of every doorbell activation without any network connection, subscription, or app.
The 0.3 megapixel CMOS camera captures 160-degree wide-angle images that show the full door area rather than the narrow tunnel view of a standard peephole. The built-in automatic infrared (IR) feature activates in low-light and nighttime conditions without any manual switching. You get a clear image in darkness that a conventional peephole cannot provide.

Why Electronic Over Conventional for Commercial Applications
For hotel room doors, apartment unit entry doors, hospital patient rooms, and commercial office suite doors, the electronic viewer solves the accessibility problem that conventional peepholes create. A standard peephole is drilled at one height. An occupant in a wheelchair, a child, or a shorter adult cannot comfortably use it. The ELDVBEL150's inside LCD monitor can be viewed from a seated position or at arm's length, making it accessible to any occupant without crouching or standing on tiptoe.
The 100-image storage log is also valuable for commercial applications where door activity documentation matters. Every doorbell activation is automatically captured and stored. That's a security record that a conventional peephole can never provide.
