Best Door Viewers of 2025

“I found this door viewer to be a perfect replacement for my old one. The previous lens was scratched from door decorations, making it hard to see who was outside. Now, the problem is fixed! It was very easy to install, looks great, and the view is wide and clear.”

“Finding a 1/2" bore size was challenging, but this was one of only two options available. I was pleased that it offered an Aged Bronze finish and had good reviews. Although the 1/2" is actually 9/16", the installation was straightforward and the quality seems good at a reasonable price.”

“The viewer works pretty well, though it could be a bit clearer. My main issue was that it required an unusual drill bit size of 9/16", which I didn't have. I had to make a trip to buy it, but the installation took under one minute.”

"I had to make a decent-sized hole in my door, but once I did, the installation was a breeze. This peephole is very useful and offers a good-sized view without needing batteries. The design is excellent, although it's plastic, and the image clarity isn't up to my standards, but it works better than my previous one. I was able to identify my neighbor knocking at night, which is a plus, but it does need some light."

"For the price, I find this product great. While it's not as heavy-duty as my previous one, it's lightweight and easy to handle. The view is clear without distortion, though it can appear cloudy. I can see who's at my door without having to tiptoe up and touch it. The external part prevents anyone from looking into my home, which is a plus. I definitely recommend it!"

"I bought this peephole for the door from my garage to the laundry room so I wouldn't accidentally slam the door on my wife. I thought about a typical peephole viewer, but when I saw this large 2-inch screen, I was sold. The build quality seems fine with high-impact plastic, and it was easy to install, requiring a larger hole. However, it uses mirrors, which flip the image, making everything appear backwards. Unfortunately, the large frosted glass screen is so dim that I couldn't see anything, so I returned it for a traditional lens viewer, which works much better."

“I found the installation very simple, taking me less than 10 minutes. The view is great even from 8 feet away, and I appreciate that no one can see in from the outside.”

“After installing this door viewer, I was amazed at how clear it is to see who’s outside while remaining unseen. I’m considering getting one for my elderly parents as well.”

“We absolutely love this Door Scope! Everyone who visits us wants one too. No more squinting through a tiny peephole; this captures a wide view and looks great!”

“I never thought I would find this old-school New York City-style device. It just works! The loud bell is easy to install, and the eyepiece is crystal clear.”

“I bought this doorbell to replace the one on my 1978 Condo Front door, and it's the same doorbell! It looks great and works perfectly!”

“I got this to replace my current doorbell and peep hole because my old lens was foggy. This new one is the perfect replacement with a wider view and clear lens.”

"As a DIY'er, I found the installation straightforward. I recommend using a 9/16 wood paddle bit and measuring carefully. I was surprised to find 32" exterior doors, so I always double-check my measurements."

"I had a great experience with this product. It's easy to install and it works great! The quality is impressive for the price."

"I'm still waiting for my son to find a drill bit, but I believe I can install this where I can see out of it without any issues."

"I needed two peep holes for my exterior doors. With so many options on Amazon, I was overwhelmed but settled on this one after seeing it was a bestseller. It arrived quickly and was in perfect condition. Installation was straightforward, and the view is much wider than expected. For just $8, it provides peace of mind at night. I just ordered another for my back door!"

"I’m using this on our master bedroom door for added security. It allows us to see outside without unlocking the door, which is a huge plus. The installation was simple, and it blends well with the door. We’re very pleased with this inexpensive option!"

"After reading reviews, I decided to buy this door-viewer. It’s well-made, easy to install, and has excellent clarity. I initially wanted a different style, but this one turned out to be the best choice. The only downside is the etched name on the cover, but I hardly notice it now. For the price, it’s an incredible value!”

"I found it easy to install with a 15/16 drill bit. It fits flush to the door and I can see clearly in all directions of my front porch."

"This viewer was perfect for my installation need. I would definitely purchase it again."

"While the optics are not very good, it fits my door well and functions fine. Just a heads up, if you need to remove it, the front can unscrew and the plastic lenses might fall out."

“I found this door viewer to be fantastic! The image quality is crystal clear thanks to the glass lens, and I love the 220-degree viewing angle that gives me a wide view of everything outside. Installation was a breeze, and it looks really sleek. I would highly recommend it!”

“I changed out my old, blurry peep hole viewer with this one. It was a great price and came with a high-quality drill bit. I had to drill out the existing hole slightly, but the process took just a few minutes. I highly recommend this product!”

“I’m not a carpenter, but with the tool provided, I managed to install the peep hole by myself. It looks great and works well, making it a good deal overall!”

"After moving into a new home, I found that the front door lacked a peephole. I initially considered a doorbell camera, but opted for this simpler solution first. Installation took longer than expected since I lacked the 5/8" drill bit. Once I got it, the setup was quick and easy. I positioned it well at eye level, and the view is much clearer than my previous homes, though I doubt it reaches the advertised 220° angle. It's an improvement for now until I decide on a more high-tech option."

"I bought this to replace our old door viewer, which was very dirty and unclear. The installation was straightforward - just drill a hole and screw it in. I would definitely recommend this product to anyone in need of a replacement. The sliding cover is a nice touch too!"

"I really enjoy this peephole. Its larger size adds interest to my door, and it matches nicely with my door handle. I do wish it was suitable for slightly thinner doors. While I can screw it tight, it obscures the privacy aperture a bit. Despite that, the finish is beautiful enough that I’m okay with it."

"I recently bought the door scope, and it's a game changer. I can see who's at my front door from a solid 7 feet away. No more guessing or peeking through the blinds! The price was fantastic, and the quality is impressive. Installation was a breeze; it took me only 20 minutes. Plus, it’s well-insulated, keeping out the cold air. Overall, I’m thrilled with my purchase and would recommend it to anyone!"

"I installed this for a neighbor and was impressed! The aluminum housing feels sturdy, and the image is crisp and clear. You stand back to view it, which is a nice change from traditional peepholes. Just keep in mind that the image is reversed. I think it's a fun and effective alternative!"

"We bought this for our new door. It provides a fantastic view, even if it is reversed. My only issue was with alignment; I followed the template, but the image is slightly tilted. Regardless, we’re really happy with it!"
