Best Door Viewers in 2020



Door Viewer Peephole, Solid Brass 220-degree Door Viewer with Heavy Duty Rotating Privacy Cover for 1-3/8" to 2-1/6" Doors for Home Office Hotel (Black) (Black) Review:


If you read the product description you will see that a 9/16 inch drill bit is advised. If you carefully follow those instructions you will have a beautiful hole that is ALMOST big enough to install this peephole. However, if you actually want the peephole installed IN the door, you will need to drill a 5/8 inch hole. Not normally a problem but I was installing this thing 200 miles from my home (and extra drill bits) at my daughter's house and ended up having to go buy another bigger bit to get it installed. Frustrating...



AP Photo Illuminated Slide Viewer Battery Operated & Pressure Activated Transparency Viewer for 2x2 & 35mm Photographs, Film, Pictures Tabletop & Handheld Portable Device| Made In Europe Review:


I am going through thousands of old family slides and needed an inexpensive quick way to review slides before cleaning them and deciding to scan them or not. Very easy to use. Pushing the slide into the viewer switches the backlight on and releasing it turns the light off. This was perfect for my purposes. I could easily get a sense of who or what the slide was about and then make a decision as to whether to scan it or not.

It's not a very large screen but it's just fine for what I wanted to do. And reasonably priced.



National Hardware N330-712 V805 Door Viewer in Satin Nickel Review:


I'm not sure what "National Hardware" is, but the item that arrived is a Stanley model N330. Once installed, the viewer yields good results. It provides a clear, wide angle view. From the inside, viewing a person standing near the door, you can view the top of the head down to about waist level. With no one around the door, I can easily view the doormat lying on the step, and the entire surrounding area.

Now, for downsides. This item ships in a tiny package that contains absolutely no instructions. I tried to find instructions on Stanley's website, without success. Why not spend a penny to include a sheet of instructions?

In my opinion, a bit of guidance would be helpful when installing the viewer in a steel door. Steel doors are not solid metal, but are usually made of two thin layers of steel surrounding a foam core. The thin metal is easily chewed up by a half inch drill bit, even when drilling a smaller pilot hole first. A rough drill hole isn't a problem on the outside of the door because of the very large flange on the viewer. However, on the inside, you have to be very careful to drill a perfect hole because the viewer itself provides almost zero coverage over an imperfect drill hole. I drilled very slowly and carefully in a metal door, and still you can see some rough edges on the inside if you look closely. I think Stanley should probably provide a larger flange to cover the drill hole on the inside of the door.

I would recommend this item for wood doors without hesitation. However, if you have a steel door and have never drilled into one before, I would recommend installing very carefully. (Update: Some of the comments on this review have good input on this issue).



TOGU TG2814YG-AB Brass UL Listed 220-degree Door Viewer with Heavy Duty Privacy Cover for 1-3/8" to 2-1/6" Doors, Antique Bronze Finish Review:


I needed 2 peep holes for the 2 exterior doors in my home. With 1,000+ listings on Amazon for peep holes, i thought I was going to have to read just as many reviews before I decided which to buy. I knew I didn't want to spend more than $10 each, so that narrowed it down a bit. I finally choose this one (I think it was an Amazon best seller or something similar) but only bought one just to make sure it was what I wanted. It arrived in just a few days and was in perfect condition. No scratches, no dents, no cracks. It unscrews easily into 2 pieces, so you can slide each piece in from either side of your door and screw it back together, and tighten in your door. It states to use a 9/16" drill bit (or spade) on your door to install peep hole in. I didn't have one on hand, but did have a 5/8" spade bit. I used this and it installed easily. The 1/16" difference made little difference. There are even 2 slight notches on one end to help tighten it up in the door. The wide angle does work, and gives you a nice wide view of your porch, or whatever your view might be. I was able to see much more than I expected. The peep hole cover on the inside is a nice touch, although you can not see inside when looking thru peep hole from outside, so like double security for that if it concerns you. No one is seeing inside thru this peep hole. This is an extremely good buy for $8 bucks. For $8, you get piece of mind when you're able to know who's knocking on your door late at night BEFORE you open your door. For me, that's an awesome deal. I just ordered the second one for my back door. If a little more security is what you're looking for, and you can't afford one of the new video door bells, and can't see who's knocking without opening your door, this should be a must for you.



TOGU TG2614YG-SN Brass UL Listed 220-degree Door Viewer with Heavy Duty Privacy Cover for 1-3/8" to 2-1/6" Doors, Brushed Nickel Finish Review:


We are using this indoors on our master bedroom door. For security reasons we keep our bedroom door locked at night. A few times we've had an alarm sensor on one of our outside doors fail and give off an alarm. Not knowing whether or not it is a false alarm, we had no way of ascertaining if anyone may have actually broken in without unlocking and opening the door. With this peep hole viewer we can see what's going on outside of our bedroom without unlocking the door. With the wide angle view we can look up and down the hallway outside our bedroom. It installed very easily, and looks very unobtrusive. Despite that fact that it is impossible to look in the other way, the security cover was a plus for my wife. We are VERY happy with this fairly inexpensive door viewer. (HELPFUL HINT - you may need 2 small flat blade type screwdrivers to tighten this during installation - I had a simple solution, a watch case removal tool that had 2 adjustable flat blades that worked perfectly.)



Ives by Schlage 698P-B716 One-Way Wide Angle Viewer Review:


We needed a matched pair for our new home's front and back door. Loved the finish of these and the price. Be aware that there were no directions included but we didn't need them. Will warn you that you need to have a clean, sharp 9/16ths drill bit & if you do not know how to install one please google it or check youtube to find the instructions. You do not want to deal with what happens when you have a whole in your door the wrong size or shape. :)
After 10+ years in building maintenance we knew that the only brand we wanted was Schlage for these. We only use them for locks and peepholes they have excellent products and we have never had an issue in multiple buildings so that is all we use in our home.



Prime-Line Products U 10313 Door Viewer, 9/16 in. Bore, 180-Degree View Angle, Classic Bronze, U.L. Listed Review:


Very easy to install in terms of the actual product and very clear view outside. Now I did make 1 mistake in drilling the hole. I bought a drill for a wood door and it didn't work out because my front door is metal! I did not know this. So I made a mess of things initially before I realized something was wrong. My fault completely. I love how this door peeper has such a great clear and wide view. From outside in, you cannot see anything as well. I don't know if there are reverse door peeper tools that someone can use, but if there is, they'd only get a view of the stairway...so I'm not worried. To tighten the peephole, I used a quarter and it worked.
