220° Wide-Angle Door Viewer (Peephole)
See the whole doorstep before you open the door.
- 220° field of viewThe wide-angle glass lens shows the step and the sides of the doorway, so someone standing off to one side is still in view.
- Fits your doorThe barrel adjusts in length for different door thicknesses. Swap out the old peephole or fit it to a newly drilled hole.
- No Wi-Fi, no batteryThere is nothing to charge, pair or update. It works in a power cut and it never goes offline.
- Three finishesBlack, Chrome or Gold, so it sits next to your handle and hinges without looking like an add-on.
Why the door viewer
Know who is there before the door opens.
Most front doors get opened on trust. Someone knocks, you’re in the middle of something, and the door is open before you’ve decided if you wanted it to be. Usually it’s a delivery or a neighbor. The point of a viewer is that you get to know that first, and decide from the inside.
Old peepholes make that hard. A narrow lens shows a small circle straight ahead, so a person who steps to the side of the frame drops out of it, and so does whatever is on the porch. People stop trusting what they see and open the door to check, which defeats the reason the hole is there. A tool you don’t trust is a tool you stop using.
A wider lens fixes the habit, not just the view. When one glance through the door shows the whole step, it’s quick enough that people do it every time. Then the door opens because you chose to open it, which is the whole job of a front door. It takes one glance, and nobody on the step ever knows you looked.
Look first, open second. A wide lens makes that the easy order.
The old peephole out, a wider one in.
If your door already has a peephole, this is a swap. The old viewer comes out in two halves, the new barrel is set to the thickness of your door, and the two halves of the new one thread together through the same hole. No wiring, no power, and the door stays on its hinges the whole time.
If the door has no viewer yet, it needs one straight hole drilled through at eye height. Check the barrel against your drill bit before you start, and drill from both sides to keep the faces clean. If you aren’t sure about your door, send us its thickness and we’ll tell you what we know before you order.
Setup is a swap, not a project
Measure your door
Check how thick the door is and, if there’s an old peephole, the size of its hole. The barrel adjusts in length to suit different thicknesses.
Take the old one out
Unscrew the inside half of the old viewer and push the outside half out. For a door with no viewer, drill one straight hole at eye height instead.
Fit the outer half
Push the outer half of the new viewer into the hole from the porch side.
Thread in the inside half
From inside, thread the eyepiece half in until the viewer sits snug on both faces of the door. Look through it and check you can see the whole step.
Any door you open to people you can’t see
Apartment doors onto a shared hallway, front doors with no window beside them, side doors that open onto a driveway. If the only way to see who’s there is to open up, this is the cheapest fix on the list. It is $16.99, it needs no power, and it goes in with the door still on its hinges. If it doesn’t do what you just read, send it back inside 30 days. Shipping to the US, Canada, the UK, Australia and New Zealand is free and tracked, and most orders arrive 1 to 3 weeks after ordering.
The viewer covers the knock. The alarm covers the rest.
A viewer helps when someone knocks; it does nothing when someone skips the knock and tries to force the door or the glass beside it. The TremShield Alarm sticks onto that door or window and fires a 125 dB siren the moment it’s forced, with no Wi-Fi and no subscription. One alarm is $29.99; six are $99, which is $16.50 per alarm (Save $80.94).
