The conclusion The viewer to read first on this shelf, because it is one of only two that tell you whether it will fit: 40 to 100 mm (1.57 to 3.94 in) of door, 14 to 28 mm (0.55 to 1.10 in) of bore, an indoor unit measured to the millimeter. A 3.5-inch screen, a 120-degree angle stated as actual, a low-battery warning and no standby drain. It is the same module as the H-COME listing here, it has no night vision at all, and the four AAA cells are not in the box.

No night vision. No storage. No capture. No screen resolution.
Both fitting measurements, published
Which is the reason to read this listing first.
The door: 40 to 100 mm (1.57 to 3.94 in) thick. The bore: 14 to 28 mm (0.55 to 1.10 in).
This shelf’s introduction calls door thickness the specification to check first, and
the buying tip says to measure the barrel diameter rather than the door alone.
At least two of the nine viewers on this shelf publish neither figure.
A 14 mm (0.55 in) minimum means most existing peepholes take it as they are. A 12 mm (0.47 in) one
needs enlarging, and in a fire door that is a job with consequences.
The same module as the H-COME
Identical to the millimeter.
Indoor unit 120 × 62 × 20 mm (4.72 × 2.44 × 0.79 in) on both. Same 14–28 mm (0.55 to 1.10 in) bore. Same 3.5-inch screen.
Same 120 degrees. Same four AAA cells, not included, on both.
Two figures differ: door thickness 40–100 here against 35–100 there, and a
1 Mega sensor against a claimed 2 Mega.
Fifty-eight dollars against fifty-six. The thinner-door range is the real
difference, and it runs the other way.
Nothing at night
No lamps, no claim.
The picture is whatever the landing light gives. In an unlit communal corridor
that is nothing.
One viewer on this shelf has two 850 nm infrared lamps. It is also the one that
publishes no door thickness at all.

What reassures, and what does not
Strengths
Both fitting measurements published: 40–100 mm (1.57 to 3.94 in) door, 14–28 mm (0.55 to 1.10 in) bore
A 14 mm (0.55 in) minimum bore, so most existing peepholes fit without drilling
A 3.5-inch screen, the larger of the two sizes here
The viewing angle stated as actual rather than diagonal
A low-battery alert before the cells die
Press to wake, so no standby drain between uses
Compromises
Four AAA cells are not included, stated in the title
No night vision, so a dark landing shows nothing
No capture and no storage of any kind
A 1 Mega sensor, where the H-COME twin claims 2 Mega
The screen resolution is not published
Fifty-eight dollars, the most expensive of the three non-recording viewers here
Specifications
Door thickness
40–100 mm (1.57 to 3.94 in) — stated. This shelf's introduction calls this the specification to check first, because the barrel has to span the door and clamp on both sides. At least two of the nine viewers on this shelf publish it
Peephole bore
14–28 mm (0.55 to 1.10 in) — stated, which is wider than the 14–16 mm (0.55 to 0.63 in) this shelf's buying tip says most viewers want. A 12 mm (0.47 in) peephole still needs the bore enlarging; anything from 14 mm (0.55 in) up fits as it is
Screen
3.5-inch high-definition color LCD — stated. No resolution figure for the screen itself
Resolution
A 1 Mega CMOS sensor — stated as a sensor size rather than an image resolution. No pixel dimensions and no video format appear
Field of view
120 degrees, stated as the actual viewing angle — the word actual is unusual and worth noting, since lens angles are routinely quoted diagonally
Battery
Four AAA cells, not included — stated in the title, with a low-power alert to warn before they fail. Pressing the button wakes the screen, so there is no standby drain
Fitting
Indoor unit 120 × 62 × 20 mm (4.72 × 2.44 × 0.79 in), outdoor camera 32 mm (1.26 in) in diameter — both stated. The 32 mm (1.26 in) outdoor plate covers the marks an old peephole leaves
Storage
None. No memory, no card slot and no capture: the screen shows the landing while the button is held
Motion detection
None published. Nothing on this shelf captures on motion

The questions we are asked
Will it fit my door?
This is the one listing on the shelf that lets you answer that before ordering, which is why it is worth reading first. Two measurements matter and both are published: the door must be between 40 and 100 mm (3.94 in) thick, and the existing peephole bore between 14 and 28 mm (1.10 in). Measure the bore, not just the door — this shelf's buying tip is explicit that most viewers want 14 to 16 mm (0.55 to 0.63 in) and an older 12 mm (0.47 in) peephole means enlarging the hole, which in a fire door is a job with consequences. At least two of the nine viewers here publish neither figure.
Is it the same unit as the H-COME?
Almost certainly the same module in different packaging. Both publish an indoor unit of 120 by 62 by 20 millimeters — identical to the millimeter — the same 14 to 28 mm (0.55 to 1.10 in) bore range, the same 3.5-inch screen, the same 120-degree angle and the same four AAA cells not included. Two figures differ: this one states 40 to 100 mm (1.57 to 3.94 in) of door thickness against the H-COME's 35 to 100, and a 1 Mega sensor against its 2 Mega. At fifty-eight and fifty-six dollars the prices are effectively the same, so the thinner-door range is the real distinction.
What happens at night?
Very little, and the shelf is clear about which viewer solves this. There are no infrared lamps here and no night vision claim, so the picture is whatever the landing light gives you — in a dark communal corridor, nothing useful. The H-COME listing says the same thing about itself in plain words. One viewer on this shelf has two 850 nm infrared lamps, and if the landing is unlit that is the only one of the four worth considering; it also, awkwardly, publishes no door thickness range at all.

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

3-inch TFT LCD · 1 MP IR camera with two 850 nm infrared lamps, the only night vision here · 120° · 75 photos to built-in memory, no card · 1200 mAh lithium battery, up to 180 days standby · zinc alloy · NO door thickness range and NO peephole bore published
The only viewer here that sees in the dark, stores pictures and recharges — and the only one that will not tell you whether it fits your door.
Best for: An unlit communal landing, on a door whose thickness and bore you can confirm with the seller first
