Earl DiamondSolid Brass Door Viewer Peephole, 220-Degree Security Peephole with Heavy Duty Rotating Privacy Cover for 1-21/32" to 2-1/8" Doors for Home Office Hotel - Modern Black Finish

Very good looking! I can see wall-to-wall on the porch. It’s clear and it’s bigger than my old one that I had to remove. I chose this one because it had metal and glass, the other one I was looking at was all plastic. Installation was a breeze, except the drill did splinter the exterior of the old door a little bit, which will be repaired later.

Best door viewer that I've tried. The large diameter tube and the rear lens give a clear wide view. Don't have to put eye real close to see. All metal, well made. Like the push up cover. Looks good from inside.Obviously the 220 degree view is inaccurate (a flat door only allows for 180 max) but the view is great. Must be a typo. Would buy again.

Installed on my front door. Easy install and the wide angel view is great.

The 220 degree FOV claim is preposterous. The door itself limits you to 180 and this is more like 150 or so. But I already knew that. Otherwise the image quality is terrific. The large barrel and rear optics provide for a bright and sharp view. You get a full view even one to two inches away so you don't have to crane your neck getting your eye right on top of it.No comparison to older half-inch diameter peepholes. View is nice and linear, no parallax distortion. Very happy.

We had no way of seeing who was at the other end so I invested in a little viewer to see what evil lurks out there. One needs an auger bit to get a large hole in place. Followed by a good half round file to clean the hole so the viewer slides through. It works fairly well and serves the purpose. As crime improves we may have to improvise and get an electronic battery driven view finder. This way one can see from another perspective and not be right at the door. The way things are now, I fear someone may shoot through the door directly at the viewer, if it's not opened up or quick enough. Times have changed.So I can recommend this viewfinder.

Cheapest door viewer with a reverse blocker. Super easy to install . Cheap package deal with the drill bit Arbor and whole driller. You can buy a door viewer at home depot for about $8 + another $12 for the reverse blocker. Limited view but super clear. I can see three neighbors across the street, but a somewhat limited view of about 1 ft out from the door, in aspects of below and peripheral vision views.

It's almost twice the size of the one I got at the big-box years ago, so it gathers almost four times the light, for a bright image. The shutter is why I wanted it, though. With the shutter closed, no one can see if there's anyone behind the door.

This peep hole door viewer was made to last. The glass bezels were clear and the fitment into the brass housing was secure and easy to install. I also noticed on the viewer that guests were not able to see inside as you approached your door. Excellent purchase for your safety.
