6 Best Door Viewer Reviews

If you want to get a door viewer for yourself, you will need to look at some quality products. And that’s what we offer here. Below are the reviews of the top door viewers on the market.

1. National Hardware N330-712 V805 Door Viewer

If you ask me, “what is the best door peephole viewer?”, then I’d probably say that this one is the best peephole viewer out there. Before buying this, you have to know the thickness of your door. This peephole viewer can only fit if the door is at least 2 inches thick. Otherwise, this product will be pretty useless for you.

As is the case for any peephole viewer, you have to drill a hole to install it. For this particular viewer, a 0.5-inch hole will suffice. This makes it very easy to install and use as all you have to do is determine the thickness and drill a hole. And this ease of use is one of the biggest pros of this product.

This viewer is made of brass metal, which is very durable. The overall construction of the peephole viewer is excellent, and it can easily stand the test of time. Durability is one of the more important features of a peephole viewer. And this one accomplishes that in spades.

It also has a viewing angle of 160 degrees, which is another huge plus. The viewing angle determines how much of the outside you will be able to see through the peephole, and 160 degrees is a great angle.

But if there is one flaw we could point at, it would have to be the image quality. The lens is made of simple glass and doesn’t offer anything special. While this isn't necessarily bad, it does pale in comparison with other products in the market, and it could definitely use some improvement.

Pros

  • Great viewing angle
  • Setting this thing up is a breeze
  • Made of brass and highly durable
  • Comes at a reasonable good price

Cons

  • Comparatively bad image quality

2. Digitharbor 3.5 Inches TFT LCD Screen Digital Door Peephole Viewer

This is the first digital door viewer that we will review in this article. The first thing to notice here is that this product is much more expensive than the previous one, and the answer is simple. And digital viewers do cost more. So if you are looking for a more budget-friendly product, you are better off ignoring this one.

But while this product is expensive, it delivers when it comes to performance. Its lens isn’t any ordinary glass lens. Instead, it has a CMOS optical lens. Not only that, but this is also a lens of 3 lac pixels. So when it comes to image quality, it definitely delivers.

Unlike the previous product, the thickness required in the door is much higher. Your door must be at least 3.5 inches thick if you want to buy and use this product.

The size of the hole may vary. But the hole needs to be in the range of 0.5 inches - 1.8 inches. This uncertainty is one of the flaws of the product. Furthermore, this door viewer is much tougher to install and comes with more complexities.

And this door viewer requires batteries to function properly. This is an extra hassle that you have to bear. But it should be noted that this product does not come with batteries. If you are buying this product, you will have to get batteries of your own.

The viewing angle on this viewer is problematic as it is only 150 degrees. This greatly limits your field of view, and that is a pretty annoying flaw. However, this product has an impressive build. It is made of solid metal. This ensures that this product is durable and can serve you for long periods of time.

As we have mentioned, that is one of the major requirements of any product, especially a product that you are trusting to keep you safe and vigilant.

It also has a very good design. This product is thin and doesn't slack off when it comes to style. The full black outline also adds to its style. This is a minor detail, but for those who care about style, this one is definitely going to stick out.

Pros

  • Great image quality
  • Made of durable materials
  • Offers more security than a peephole
  • Very good design

Cons

  • Bad viewing angle
  • Difficult to install

3. TOGU TG2814YG Door Viewer

This is the second peephole viewer on our list. Just like any other peephole viewers, it is on the cheaper side, and for its price, it offers a lot of great features.

The first thing that needs to be mentioned about this product is the viewing angle. It has a viewing angle of 220 degrees. This is much more than all of the door viewers we have reviewed so far, and it is one of the highest viewing angles in the market.

And this greatly increases your range of sight when you are looking through the peephole, and you can see everything on the outside much clearly.

While it does offer a higher range of sight, the quality of said sight is quite average. It does use optical lenses. But there really isn't anything else to add. It is definitely serviceable, but there are other products in the market that offer more than serviceable at a similar price.

But the construction of this product is definitely top-notch. It is made of solid brass metal. As we have mentioned previously, brass metal is one of the finest materials to use in a peephole viewer. It makes the viewer durable and long-lasting, which is an absolute essential in products like these.

Moreover, this peephole viewer is applicable to many types of doors. The thickness requirement is variable. It can fit in any doors providing its thickness is in the range of 1.375-2.2 inches.

All you have to do is drill a hole in your door. The hole doesn't need to be larger than 0.5-inch. So it is pretty clear that this peephole viewer is extremely easy to install, and that's a huge relief. You don't want a door viewer that is difficult to install, adding to your troubles.

Pros

  • The viewing angle is great
  • Constructed of durable brass metal
  • Setting up this thing would be easy

Cons

  • Average image quality

4. 3.5" LCD HD Screen Peephole Viewer

Now it is time to review the second digital peephole viewer on our list. This one costs about the same as the last digital door viewer on our list, and it offers some great features.

The first thing that is worth mentioning is the camera. And the image quality in this camera is extremely good. This is a high definition camera that offers 720p resolution. At this price, this is a huge plus. It also increases the security of your home by giving you a much clearer view of the outside.

While the image quality is excellent in this product, the viewing angle could definitely use some improvements. It has a viewing angle of only 120 degrees, which is quite low. You may get a high-quality view, but the range of that view is greatly limited in this product.

However, it definitely has durability covered. It is made of zinc alloy. Zinc alloy is a very good durable material, and it makes sure the door viewer can last a long time.

Moreover, the last digital door viewer on our list had an issue with its installation process. It was quite difficult to install. This one doesn't have that issue. It is very easy to install and doesn't add extra trouble for you. It also doesn't require any batteries. Any electrical power source is good enough for this door viewer.

Pros

  • The image quality is top-notch
  • Will last years
  • Easy to install
  • No batteries required

Cons

  • The viewing angle isn’t satisfactory

5. Home Video Door Eye Viewer

This is the last digital door viewer we are going to review in this article. And the first thing that needs to be mentioned about this product is its price. It is quite expensive, even for a digital eye viewer. So if you want to avoid something that may take a toll on your budget, it would be best to avoid this.

But let's see if this door viewer can redeem itself through its performance. The best part about this door viewer is its camera. It is a really good HD camera that offers 720p resolution. This makes the view on the outside much clearer and makes your house even more secure.

Similar to the previous entry, this door viewer has an excellent camera which provides great image quality but has a poor viewing angle. Just like the last product on our list, this door viewer also has a 120-degree viewing angle.

We have already talked about why a good viewing angle is necessary and why 120 degrees just doesn't serve you that well. So this is one of the flaws of this device. But a great advantage for using this device has to be the fact that it can be used on any door.

For all the door viewers we have mentioned so far, there was a fixed thickness requirement for the door. Otherwise, the product could not be used. This door viewer doesn't have that problem. It is applicable to any door of any thickness.

And this feature also makes it very easy to install as you don't really have to think about the thickness of your door. So that is one less hassle for you.

Furthermore, the device is very easy to use and configure. The operating software used on this device is very simple and accessible. It is made in such a way that even kids will be able to use it with little to no difficulty.

Lastly, it also has an incredibly thin body, which makes it look very stylish. And as it is for any product of this kind, style is a minor detail that goes a long way to making you feel good.

Pros

  • Impressive image quality
  • Very good design
  • Installation is hassle-free
  • Extremely easy to operate
  • Applicable for all doors

Cons

  • Poor viewing angle
  • Comparatively more expensive

6. Door Viewer Peephole Camera 

Finally, we have arrived at the last entry on our list. This one is a non-digital peephole viewer with a solid performance.

Firstly we have to mention its optical lens. This product uses an HD optical lens, which is a rarity for non-digital peephole viewers. And this makes the view on the outside much clearer, and that is one of the primary jobs of a peephole viewer.

It also has a great viewing angle of 220 degrees. So not only is the image quality excellent, but the range of your outside view will also increase greatly if you are to purchase this product.

Like most non-digital peephole viewers, this one is also very easy to install. But you do have to make sure the thickness of your door is appropriate. This product requires a 1.375-2.2 inch thick door at the very least. After that, all you need todo is drill a hole. A 0.5-inch hole is more than enough for this product.

However, a huge drawback of this product is its construction. Unlike all the previous entries on this list, this door viewer is made of plastic. It goes without saying that metal is more durable than plastic. So this may be a turn off for many as this door viewer is not guaranteed to serve you for a long time.

Pros

  • The viewing angle is amazing
  • Will have no complaints regarding the quality of the image
  • Easy setup

Cons

  • Not very durable

Buying Considerations

Now that you are familiar with 6 of the best door eye viewers in the market, it is time to know which one is the ideal option for you. Everyone has their own unique set of requirements, and based on that, the buying considerations vary from person to person.

In this section of the article, we will give you a general overview of the things that you need to be careful about before buying a door viewer.

Durability 

This is a no brainer. Whenever you buy any product, you should first and foremost make sure that this product can last a long time. You don't want it to get ruined after a short period of time, as that will increase your troubles considerably.

To know if your door viewer is durable or not, all you have to do is look at its construction. If it is made of solid metal (brass, zinc alloy, aluminum alloy, stainless steel, etc.), then there is a high chance that the viewer will be durable and long-lasting.

Plastic door viewers, however, do not guarantee that. So for more durability, it is best to avoid those.

Thickness of Your Door

All peephole viewers are not applicable to all doors. Most viewers have a thickness requirement, which, if unfulfilled, the viewer will not be applicable to that door.

So you must make sure that you know the thickness requirement for any door viewer you want to purchase. You must also know the thickness of your door itself to make sure the product is compatible with it.

Viewing Angle

This is one of the most important aspects of a door viewer. The viewing angle is what determines how much of the outside you can view through your door viewer. You want to get a door viewer that gives you a wide range of views so that you can clearly see everything on the outside.

A viewing angle of 180 degrees or above is ideal. But a 160-degree viewing angle is also serviceable.

Image Quality

This refers to the quality of the view of the outside, i.e., how clear the view on the outside is. A door viewer is a product that you rely on to keep you safe and vigilant. So whenever you look through it, you should make sure that the image of the outside is as clear as possible.

A door viewer with a high definition optical lens is ideal for that purpose.

Ease

By this, we mean both the ease of use and the ease of installation. You don't want to buy a door viewer that is extremely difficult to install as that will just add to your troubles and leave room for mistakes.

And you also don't want a door viewer that is difficult to use and configure (a problem seen very often in digital door viewers). So you should be well informed about the installation process of the door viewer to make sure of their ease.

Digital or Analog

A digital door viewer has its advantages. Firstly, you don't have to go directly to the door to know who is on the outside. You can view the outside of your house through a camera. Secondly, the view of the outside is much clearer. Thirdly, it gives you more security and more options.

digital door viewer

But it also has its fair share of disadvantages. For example, the digital door viewer is much more expensive than the non-digital ones. They also require an electrical power source to run. Again, they are much more difficult to handle, and the likelihood of it breaking down is much more than a non-digital door viewer.

And a non-digital door viewer can be quite advantageous. Firstly, it is very cheap and thus extremely easy to buy. Secondly, non-digital viewers usually have a higher viewing angle compared to the digital ones. Thirdly, these viewers have much less risk of breaking down.

While these non-digital peepholes have their advantages, the disadvantages are apparent. They don't offer nearly as much security as a digital viewer can. Also, you directly have to go to the door to see whoever is on the outside.

Again, the image quality of these types of peephole viewers is rarely as good as the digital ones. Furthermore, you can back up all the videos of the digital door viewer to your computer. But this isn't a luxury afforded by a non-digital peephole viewer.

So keeping the respective advantages and disadvantages in mind, select the door viewer that is the best for you and make your house safe and secured.

How to Install a Door Viewer

So far, we have reviewed the best door viewers available in the market and mentioned all the things that you should consider before buying a door viewer.

Now assuming that you have bought a door viewer, you should know how to install it as installation can be a tricky process, and mistakes in it may render your door viewer completely useless. So down below, we have described exactly how you should install a peephole viewer:

Step 1: Selection of the Product

First and foremost, you have to select the door viewer that you need. We have talked about all the buying considerations of a door viewer. Based on that, you have to get a door viewer that is best for you. You have to select a door viewer that is applicable to your door.

Step 2: Choosing the Position

Next up, you have to determine the exact position where you want to set up your door viewer. At first, determine the height at which you want to set it up. Usually, a height of 120cm-170cm is good enough. You should also mark the exact position after you have determined the height.

Step 3: Drilling

After that, you have to drill a hole. The dimensions of the hole depend on the peephole viewer you have selected. Various viewers require holes of various sizes. Based on that, you have to drill the perfect hole for your door viewer.

Step 4: Applying Silicone

After you have drilled the hole, you should apply a little silicone on the internal area of the hole. Don't use too much silicone. You only have to apply a very thin layer of it.

Step 5: Final Step

Lastly, place the door viewer in its designated hole, and if it is a digital viewer, connect it to a power source. And then you are good to go.

Frequently Asked Questions

Below are the most commonly asked queries regarding door viewers:

What is a peephole camera?

A peephole camera is essentially a hybrid of a doorbell and a camera. It allows you to answer the door from any place. Once the door rings, you can check your phone or any other electrical devices provided that it is connected to the peephole camera to see who it is on the outside.

What is a digital door viewer?

It is much like a peephole camera. You can see whoever is on your doorstep through a camera. The only difference is that you cannot connect it with your phone or other electrical devices. There is a fixed camera, and you can only see the outside through that camera.

How can I protect my doorbell camera from theft?

Unfortunately, this is an issue many people have to deal with. But there are some precautions you can take to prevent this from happening to you.

Firstly, you could attach your doorbell camera to the wall to make it harder for the thief to steal. Secondly, you could get a grid box and keep your doorbell camera inside that. Thirdly, you could also secure your power cables so that any thief cannot cut them easily.

Lastly, you should always back up the videos of your camera to your computer.

Will I have to create a new peephole?

This depends on the viewer you are buying. If the dimensions of the door viewer you are getting are the same as your old one, then you don't have to create a new peephole. And if the dimensions are different, however, you have to make a new peephole.

Will my door be too thick for the door viewer?

Again, this also depends on the door viewer you are purchasing. We have mentioned the required thickness of the door for every door viewer we have reviewed. If you follow that, the thickness should not be an issue. Generally, any door of 1.5-2.5 inch thickness will be good enough for the door viewer.

Can you see someone looking through a peephole?

This might be tricky. This honestly depends on a lot of external circumstances. If there is sufficient light on your end, you might be able to see someone looking through the peephole. If there isn't, you might not. Again, if you are vigilant enough, you might notice someone looking through. It all really depends on the circumstance.

How do you put a lens on a door?

Putting a lens on a door is very similar to installing a peephole viewer. In this article, we have covered how to install a peephole viewer. Follow the same process for installing the lens.

Final Words

So now you know all about the best door viewers in the market, and you know exactly what to look for before buying them. All you have to do now is actually buy one depending on what you need. In this article, we have reviewed three digital door viewers and three-door viewers that are not digital.

Among all of them, my favorite is Digitharbor Digital Door Peephole Viewer, and the National Hardware N330-712 V805 Door Viewer due to the value they provide for the money.
