Yale Digital Door Viewer 500 (silver) review
Yale's straightforward digital viewer: a 3.2-inch screen inside, a 105° lens outside, and a live view at the press of a button. No recording, no app, no network.
The conclusion A peephole replacement, not a security camera. Judged as that, it is the sensible one.
This is not a small doorbell. It is a peephole with a screen, and reading it
as anything else leads to disappointment.
What it replaces, and who for
A conventional peephole requires leaning against the door and putting an eye
to a lens at a fixed height. For a wheelchair user, for somebody short, for
somebody whose eyesight makes a tiny lens useless, that is not a workable
arrangement. A screen at a comfortable height is.
That is the product. It shows who is outside when you press the button.
What it deliberately does not do
Record. Connect. Notify. There is no app, no account and no network, which
means nothing about your doorstep goes anywhere — and for a proportion of
buyers that is the reason to choose it over a connected model.
Fitting, which is the thing to check
Yale states doors 38 to 110 mm (1.5 to 4.3 in) thick. The other
measurement matters more: the existing peephole bore. Yale does not publish it. In this hub the Ring takes 12 to 14 mm and the Imou 14 to 26 mm: measure yours, because a hole that is too narrow has to be enlarged. On a fire door,
altering the bore is a decision to take seriously rather than casually.
Who it suits
Somebody replacing a peephole, not somebody buying a camera.

What reassures, and what does not
Strengths
No network, no app, no account — it does one thing
A screen at a comfortable height rather than an eye pressed to a lens
Doors 38 to 110 mm (1.5 to 4.3 in) thick, per Yale
From a lock manufacturer rather than an electronics brand
Compromises
105°, the narrowest view in this hub, level with the white version
Live view only — nothing is recorded
No motion capture: it shows who is there when you look
The listing states neither the power source nor the runtime

The questions we are asked
Who is a digital viewer actually for?
Anyone who cannot use a conventional peephole comfortably — because of height, because of eyesight, or because leaning against a door to look through a lens is not something they want to do. It replaces a peephole and nothing else, and for that person it is the right product rather than a doorbell.
Does it record?
No. This model shows a live image when you press the button. Nothing is stored, nothing is sent, and there is no app. That is a limitation and, for some buyers, precisely the appeal.
Will it fit my door?
Yale states doors 38 to 110 mm (1.5 to 4.3 in) thick. Measure your door and check the existing peephole bore before ordering: Yale does not publish the bore it needs, and an older peephole that is too narrow may need enlarging — which in a fire door is a job to think about carefully.
Our score
6.9/ 10
A peephole replacement, not a security camera. Judged as that, it is the sensible one.
Against the rest of the digital door viewers
Between security devices of the same category and nearby price. Shown: what they all state. A half-filled column says nothing.
3.5-inch LCD color display at 480 × 320 — stated. It is the only screen resolution published on this shelf, and a useful figure: 480 × 320 across 3.5 inches is about 165 pixels per inch, which is legible rather than sharp
120 degrees — stated, the same as every viewer on this shelf
What separates the models, in security devices
If price decides: Dioche 3.5-inch digital door viewer, 120°, 4 × AAA, at $58.
What this one costs among digital door viewers
A reference exists on these Amazon stores: France, Germany, Italy, Spain, United Kingdom, United States. Listed is not the same as in stock — availability changes daily.

The buyer this one serves, among security devices
Anyone who cannot comfortably use a conventional peephole, and does not want a connected device on the door.

3.5-inch LCD · 1 Mega CMOS · 120° actual viewing angle · door hole 14–28 mm (0.55 to 1.10 in), door thickness 40–100 mm (1.57 to 3.94 in), both published · indoor unit 120 × 62 × 20 mm (4.72 × 2.44 × 0.79 in) · outdoor camera 32 mm (1.26 in) · 4 AAA, not included · low-battery alert · press to wake, no standby drain
One of only two viewers here that publish both the door thickness range and the peephole bore — the two measurements this shelf says to check first.
Best for: A tenant replacing an existing peephole who needs to know it will fit before ordering
3.5-inch LCD · 2 Mega CMOS · 120° · door hole 14–28 mm (0.55 to 1.10 in), door thickness 35–100 mm (1.38 to 3.94 in), a wide range · indoor unit 120 × 62 × 20 mm (4.72 × 2.44 × 0.79 in) · camera ≈30 mm (1.18 in) · 4 AAA, not included · battery changed without removing the unit · the only listing here that argues against itself
The widest door range on the shelf, and the only listing on this site that tells you what its own product cannot do.
Best for: A thin apartment door — 35 mm (1.38 in) up — where the honesty about low light is worth more than a night vision claim
3.5-inch LCD at 480 × 320 — the only screen resolution published on this shelf · 720p camera claimed · 120° · zinc alloy outdoor unit · NO door thickness, NO peephole bore, NO battery, NO storage · five of its ten bullets are empty
The only listing here that publishes its screen resolution, on a page whose last five bullets contain nothing at all.
Best for: Nobody, until the seller supplies a door thickness range and a bore diameter in writing
