3.5-inch LCD Door Viewer

This wired digital peephole viewer replaces a standard door viewer with a 3.5-inch colour LCD and a 120-degree viewing angle. It fits door holes from 14 to 28 millimetres and door thicknesses from 35 to 110 millimetres. The indoor unit measures 120 by 62 by 20 millimetres and weighs 200 grams. It is suited for households wanting a simple visual monitor without smart-home integration.

Battery Power and Silent Operation

The device runs on four AAA batteries, which are not included, and has no mains connection. A low-power alert helps extend battery life during 24-hour monitoring. With no fan or moving parts, operation is completely silent. Power draw is minimal, so battery changes are infrequent under normal use.

Included Hardware for Quick Fitting

The package supplies the indoor display, the outdoor camera module with a 30-millimetre diameter, and the internal power cable linking them. Mounting hardware suits the stated door-hole and thickness ranges, allowing installation in about three minutes without special tools. No software, app or smart-home platform is bundled or required.

Questions about this item

How do I install the 3.5 inch Digital Doorbell Peephole Viewer internal power cable, and what step is often missed?

Insert the 30 mm outdoor camera through the 14-28 mm door hole, secure the 120x62x20 mm indoor unit on the 35-110 mm thick door, then connect the cable; the missed step is inserting 4 AAA batteries (not included) to power the 2 Mega CMOS sensor and 3.5 inch LCD.

What maintenance will the internal power cable and viewer need later?

Replace the 4 AAA batteries when the low-power alert triggers; the zinc-alloy body and wired connection need no lubrication, but clean the 120-degree lens occasionally to keep the 2 Mega CMOS image sharp.

What limit appears first during continuous 24-hour monitoring?

Battery drain; the 4 AAA cells power the color 3.5 inch LCD and OV sensor non-stop, so sustained use hits the low-power alert before any thermal or storage limit on this wired, non-recording viewer.
