No matter which part of the world you live in, home security is always a priority. While a robbery might not be an occurrence in your area, door salesmen and unwanted guests might be something you face more often. Wouldn’t it be great if you could see who’s outside before you open the door?

Well, door viewers and peepholes can do the job for you.

While peepholes have been in use for at least a century, door viewers are a relatively recent innovation. However, it’s not much different except for the fact that conventional peepholes required one to put his eyes right In front of the peephole to see what’s on the other side. Whereas with the door viewer, we can see who’s on the other side of the door by standing as far as 5 feet from the door.

As there are so many door viewers in the market, so choosing the right one becomes a difficult decision to make. The difference can range from the lens to the material and aesthetics to the viewing angle.

To help you with this backdrop we have decided to compile a list of our favorite Door Viewers and we will explain each one of them as much as we can. We hope you’ll leave this article with at least one door viewer in mind.

Let’s check a run-through of the best sellers down below  :

Here’s the full reviewed of  “the 7 Best Door Viewers” :

Sumnacon Large Door Viewer 220-degree

Another large door viewer that we’ve found out quite worthy is this one from Sumnacon. It’s durable, it’s affordable and it does the job very well. It shows you a 220-degree view through with you can see if a package has been left for you on the floor or if someone on the extreme left and right is either coming or going.

This is a very good option for hotel rooms and apartments, especially for those who want to have a black color door viewer. The best thing about black color is that it can fit well with doors of similar color as well as a contrasting color.

The rotating cover is also a great feature to have as it prevents outsiders from peeking inside when you’re not there. This makes it a great option for hotel rooms and offices, where privacy is at a risk.

The installation was also fairly easy, as we had no trouble drilling the hole and placing it. Although we applied silicon on the inner side of the hole to make it airtight, it isn’t necessary to do so. However, doing so will also prevent moisture and make the door viewer quite firm in its place.

What we like

  • 220- degree view
  • Comes in only one color; black
  • Lid cover provided
  • Easy installation
  • Quite durable and sturdy

Another great feature in the Royal H&H door viewer is the lid cover that prevents anyone from outside to peep inside.

Moreover, it does prove to be an easy installation, even for a layman as long as he has a drill machine. We tried installing it in metal doors, and it matched perfectly giving us the elegant feel. You will find one or the other color, perfect for your door.

It is also perfect for hotel rooms and apartments as the 220 degree is more useful in those places. A metal cover lid is provided at the inner end so that privacy can be maintained from outsiders. The main difference this door viewer has is its 28 mm diameter which is a lot more than its contemporaries.

However, one difficulty we faced with this door viewer is that the installation wasn’t as easy as other door viewers are. Since the size is a bit out of standard, drilling the same hole was difficult. We had to put some grease to fill the gaps. Although this solves the problem for a while, replacing it in the future will be a difficult task once again.

Nonetheless, some customers are looking for door viewers of this specific size, if you are one of them, then you’ve found what you’re looking for.

What we like

Another excellent door viewer that we discovered was this one from National Hardware. Now National Hardware is a manufacturer of a wide variety of goods in 15 product categories and has over 6,000 SKUs worldwide. Being as old as 1901 and enduring the two world wars, National Hardware continues to be a source of pride for the American people.

It is owing to their reputation and sheer size of the industry, National Hardware’s products are admired, trusted, and present in every district of the US. Although the manufacturer offers a replacement policy if the product develops scratches or shows signs of deterioration early on the need to ask for replacement is seldom felt. This door viewer is quite durable and will not allow scratches or deformities to take place.

However, the outside view that this door viewer provides is 160 degrees, which might seem less compared to other door viewers but is sufficient for most users. The N330-712 is compromised of four glass lenses and is scratch-less and air-tight.

Another highly demanded and found door viewer is this one from TOGU. Its Brass made but comes in 7 different color coatings. Each one of these variants delivers a classy finish that looks great on all kinds of doors.

We checked the lens quality and its amazing. If you’re a layman and you’re wondering how can a door viewer show you a view more than 180 degrees. Don’t worry you are not alone and yes; some companies are just lying about it to show that their product can do more than others.

The Buyers' Guides & Tips to

The Best Door Viewers

What to look for when buying a door viewer?

Now that we have given you our recommendation for the best door viewer, we want to further leave you with a brief guide that you can use to make a better option. After all, you might stumble on a door viewer that is not on our list but you feel a certain attraction towards it. In that case, you should consider these factors and buy it if it stands out.

  1. Durability:
    By durability, we don’t just mean, its ability to survive impacts but we are also including the scratch lessness and the airtightness of the door viewer. Door viewers are usually strong enough to survive impacts, but their shiny surfaces develop scratches over time, thereby deteriorating the smooth finish we bought it for.
    Airtightness is also very important because dust particles can get inside the door viewers and clog the lens and ultimately impacting our view. Ask for a warrantee from the dealer.
  2. Length of the door viewer:
    One of the most common mistakes people make when buying door viewers is that they buy a longer door viewer than the thickness of their door. This will lead to the door viewer coming outside the door, destroying the image of the door as well as becoming easier for robbers and thieves to plug it out.

So, measure your door’s thickness and then only look for door viewers of that length. This will also leave you with fewer options, which means easier decisions.

Some factors to consider before buying the right products:

Though the features of a door viewer may vary with models and products, but some essential things are the must. Look for the following things in a door viewer.

  • Material:
    You need to make a hole in the door for mounting the door viewer. So, changing several times, the viewer can damage the door. So, you need to pick a heavy-duty material for the viewer. You may choose a stainless-steel or brass finished product.
  • Proper Size:
    Before ordering a door viewer, make sure that you have chosen the right sizing. If you are going to replace the older one, measure the hole for ensuring proper fitting.
  • Viewing Angle:
    Viewing angle is important for seeing outside with a wide angle of view. You will find up to 220-degree Door Viewer in the market. Buy the accurate one that fulfills your requirements.


These were some of the factors we thought you should be aware of before making a purchase. We hope we have answered all of your questions and we also hope you have found your best door viewer amongst our recommendation.
