Digital Peephole Viewer for your home?


Security begins at home for your loved ones!


When it comes to protecting our family members, nothing else comes first!

The Traditional Front Door Eye Viewer- Peephole


For ages, we have been using this simple peephole to provide for home safety.

The traditional peephole viewer(non-tech) has a distorted view due to its type of fish-eye lens. There are also blind spots due to the limited viewing angle.

When was the last time you had difficulty looking out through the peephole of your front door, side door or back entrance?


I remember I had to press one eye against the tiny peephole. The view was too small to be seen.

I used to have a fear of looking into the peephole while I was a kid. Afraid that someone will poke into my eyes even though it is not possible.


Sometimes, the peephole viewer may be positioned too high such that one has to tiptoe.

It’s not that I’m not tall enough, just that some standard peephole viewers are already in place at a certain height when we moved in.

Furthermore, regardless of tall or short people, it is still not an easy task to get a clear view.

Sometimes, we will not be able to see who is standing (or even hiding) outside our doorstep.

Has anyone used the Chain Door Guard before?

Door Chain Guard

A door chain guard is a simple fixture attached to your door and door frame which allows the door to open with a small gap, restricted by a chain.

Thus, it allows communication with people outside your door.

When I was small, my house used to fix a chain door guard so that the door can be opened slightly to see who is outside your door.

Installing it is not an easy task too. You must ensure to drill the hole first, and all the other measurements. It is quite a hassle.

Most importantly, it must be firmly installed. If not, it could be easily kicked in, due to weak door restrictor or poor installation.

You might say by fixing the chain door guard seems to resolve the safety issue, yet there’s still fear within us.

Who dares to open?

If we have our family members, especially our elderly or the young ones home alone, it is something which we are very concerned. They may not be quick enough to react and close the door should an intruder try to force his/her way through with some weapon, knife or gun. Not to frighten you. Anything is possible.

It is always good to have a door chain better than none, yet it is still not a perfect solution.

Is there a solution? Definitely!

My Recommendation For You

We know about Security Cameras which can help to provide an eye for our home (If you have read my previous article on Best Wireless Home Security Systems Cameras -How to choose?

You still can do it, but if your purpose is to know who is at your doorstep, then it will not be feasible to install an IP camera outside your home.

I would recommend a digital peephole viewer for your doorstep. It will be the most appropriate choice.

What is a Digital Peephole Viewer?

There are so many choices in the market, how are we going to choose the best digital peephole viewer? What are the things we need to know?

There are a couple of things you have to know.

Let me help you. Over here, I will be showing some photos of my digital peephole viewer. So it’s useful to know what to look out for before you make that purchase.
I will show you my real-life pictures you can hardly find it elsewhere.

At least, it will be easier to show picture illustrations rather than only using words. You do not have to use your imagination due to limited pictures available which are not what we want.

Take note: The Digital Peephole Viewer pictures provided are based on the model I am using. Technically speaking, it should be quite similar unless there are features which are unique or different.

Wait! Wait! Before you make your purchase

Before I move on to share with you, there are two important factors you must take into consideration! I do not want you to waste your money and end up with another white elephant in your house.

1) Door Width

Door thickness is from 35mm to 105mm.

If it is not within the range, then you have to look for the appropriate one.

Say, if it is less than 35mm, there will be a gap and not tight. You have to think out of the box to resolve the gap issue, and sometimes it may not hold properly. If the door is thicker than 105mm, then it is not fully tightened.

You have to take your own risk.

2) Barrel Diameter

You need to check:

(I) Can the digital peephole replace the standard sized peepholes in your door?

The barrel diameter is 14mm to 22mm.

Peephole viewer set

(II) Require any additional work to install? Say, for instance, some doors do not even have a peephole, and you must first find out if it is feasible (or easy) to drill a hole through the door.

For me, it was quite an easy job, with no sweat. When I removed my traditional peephole viewer, it just fit easily into the existing hole.

Either 10 seconds, 20 seconds, 30 seconds or “Off”.

To turn off the display, simply press and hold the “Power On/Off” button (Right-hand side) for at least 1 to 2 seconds and you can let go your finger once you see the “Goodbye” message.

Display Screen Size:

Other factors to consider is, how big/wide you want the display screen to be?

I was looking for a mid-range size then. To what I had researched then, the bigger the display screen, the higher the price. Of course, different brand/model and screen display type, promotions and discounts will also be other contributing factors.

The one I am showing you over here is a 3.5 inch TFT LCD (Thin-Film-Transistor Liquid-Crystal Display) screen. TFT LCD has improved image quality.

It will not have a distorted view (Fish-eye lens) from the traditional peephole viewer.

There are different screens sizes: 2.4 inch, 3.0 inch, 3.5 inch, 4.3 inch, etc.

The Display Screen will be turned on:

(I) When someone presses the bell and a photo will be taken.

Battery Compartment:

It does not look nice on a personal view. It’s up to your preference.

Digital Peephole Viewer-Battery Compartment II

Low Power (Battery) Indicator:

Digital Peephole Viewer-Low Power Indicator

When the battery is about to turn flat, you can notice from the red battery indicator.

How long will the batteries last?

It varies. I change it about 2 to 4 months. It depends on how you used it:

  • The longer the time the display screen is on.
  • Video recording, especially the longer the recording time, it will consume more power.

How to fix or remove the Indoor Host Device?

From the picture below, the outdoor device already in place (but still can be uninstalled easily, from inside):

Digital Peephole Viewer-Battery Compartmwnt III

You can remove the Indoor Host device by disconnecting the connector.


There are many brands and models, sizes, features and functions. Hence, the price range varies from about US$ 50 to US$100 (The price is an estimate and will change over the time due to various reasons: Brand, New/Old Model &/or Version, Price competition, Sales, Promotions, Discount, etc.).

Nowadays, it has become more and more affordable as people are more willing to invest in the safety of their loved ones.


For the traditional peephole, any movement inside the house, especially when you are at the peephole, it will be noticed from the outside. We used to have that fear and do not want to get close to the peephole until after ‘cooling period’ (Lol but it’s true).

Digital Peephole Viewer is a very helpful digital device which could easily solve the difficulty of viewing through a narrow hole in the door to see outside. It has a wide display screen, and we do not have to strain our eye by peeping into a narrow hole.

It only takes a couple of seconds to check who is outside your doorstep, with the press of a button.

If you’re expecting someone, it will be easy to have a quick look before opening the door.

You will be able to see very clearly who is outside your door by looking at the brightly lit wide display screen, without any fear that the person outside will know if you are watching them. That’s the best part.

Ever since I installed it, it gives me a sense of security not only for me but my mum when I am not at home. Nowadays, burglars or intruders will be smart and definitely will avoid when they notice some device with an eye is on your door. This acts like a good ‘talisman’ (Ha).

It is very simple to install and very easy to use.

Other Features:

When I purchased mine, I did not opt for the knocking sensor feature. It works by recording the visitor(or visitors) image automatically, as soon as someone knocks at the door.

There is another type which has the motion detection sensor which automatically records the activities when there is any movement outside your doorstep. Hence, it will use up more data capacity and power consumption.

Thus, different digital peephole viewers will have their own distinct features.

What I have shared covers the basic functions which is more than sufficient. Of course, it will be good to have more features. In that case, it will definitely cost more. It’s up to individual preference.

When it comes to home security, it is not only for us but most importantly we should consider investing a digital peephole viewer when we have our seniors and children are home alone. They are the usual vulnerable groups. It provides an additional layer of security and protection for you and your loved ones.

Thank you! Cheers and Take care too!

  1. Hi Terand,

    I have read the whole review with all necessary information about the Digital Peephole Viewer Product. I understood that this digital product is very helpful for us and I believe it is more secure and high quality product. I like all of those knocking sensor feature and visitor image recording functionality. I am going to share it with my family members. I am going to buy one of those item soon. Thanks for sharing this helpful review with us.

    1. Hi Harun-or-rashid,

      Thank you for reading my post!

      Great that you love the smart device which can help to protect you and your loved ones.

      Yes, good that you like to have the knocking feature. If that is the case, I suggest you get a higher storage capacity for the MicroSD card in case the frequencies are high, especially if it is set to the video recording mode. Take note of the power source too. I do not know if the battery can last longer unless you use a DC power source.

      Let me know if you need my assistance further.

      Thank you and have a great day, Harun-or-rashid! :o)

  2. Next level technology right there, the world is evolving and we should join it in the evolution. I can still remember the out fashioned chaindoor or the see through red maid doors but with this digital peephole device everything changes. The camera feature is pin point perfect nothing can beat that the no disturb feature to is exquisite, Individuals like myself that find their privacy very precious will find that feature as God-sent. The Review is great amazing device, amazing post. Nice work admin. 

    1. Thank you for reading my article and your comment, Damola!

      Yes, we should evolve together with technology.

      I agree with you, privacy is very precious and the digital peephole is helping us in a way. I feel that my front door is giving me an extra layer of protection- “Another Invisible Gate, sent from GOD”.

      Wishing you all the best to your health and success, Damola!

  3. Wow, thanks for the polite insult..Lol

    I am still in the realm of people using the traditional peephole, but i usually see these kinds of peephole in movies but never  knew they could be obtained in the market.

    Thanks for the detailed information on the modern peephole, i should have one in my house too, but i would like to know if i can buy one and use it for several doors in the house?

  4. Lol, Rahye. Pardon me :o)

    Thank you for reading my article!

    Yeah, it’s starting to get popular. I strongly advise you to get one for yourself and your loved ones! It’s worth the investment, for home protection and convenience sake.

    With regards to your question, one device can only be installed on one door. I believe you have a backyard or side entrance?

    Please let me know if you need further assistance. I will be more than happy to help you.

    Thank you and have a great day, Rahye!

  5. Hi! Thank you very much for this very good option for a peephole. I like the fact that it takes a picture every time somebody rings the bell. I also like that it can record video.

    And what I like the most is that the price is very affordable.

    Thank you for describing all its features. I have been encouraged to buy one. It will solve a couple of problems at home. I’m sure of that.

    1. Hey Henry!

      Thank you for visiting my website and your time to read my article!

      Yes, you are right! In fact, we just require a digital peephole viewer with a few basic functions. It should be sufficient unless you need other feature.

      It is a good investment for extra protection for your family members.

      For your information, I have updated my website on the actual one I am using and add on a few more other brands/models for your reference.

      Thank you, Henry!

      Wish you all the best!

      Terand :o)

  6. Wow, this is really cool. The technology in security is really stepping up a lot. I haven’t really checked anything to do with this but thought to myself that I do need a cool security system for when I move out. Thank you for this.

    1. Great, Rachael!

      Glad that this article can help you to understand how to choose a decent Digital Peephole Viewer.
      You can never find such real-life pictures, not even from the package which only provides a few small pictures and technical specifications. Not useful enough.

      It is an investment you should not miss for your future home! Forget me not! ;p

      Thank you and all the best to you, Rachael!

      Terand :o)

  7. Hey Terand,
    Thank you for sharing the technology and explain in full detail how they work they are very good for safety like you said when you are not home to give your mum the extra protection making her feel safe.
    I do like the idea of the camera indoors so that you can see clearly who is at the door and the fact that some dont have electrical connection so there is also battery as well.

    Thank you again for sharing.

  8. Thank you, Tracey, for checking out!

    Yes, we can hardly find such detailed explanations based on my personal experience coupled with my years of technical knowledge. It is the most honest and truthful opinion, from the bottom of my heart.

    You and your family will be able to benefit a lot from it, and we can even know who had come to our doorstep even when we are not at home. Most importantly, it provides a ‘security guard’ in front of my house. You do not have to pay for the monthly security fee. Lol.

    It is highly recommended to have one at home. It is a helpful device, and you can say goodbye to your traditional peephole viewer. No more straining of your eye, with the use of widescreen.

    I love this device which does not require us to have any technical knowledge. It is so easy to install. Awesome!

    Wishing you all the best and take care too, Tracey!

    Terand :o)
