What is a Peephole Camera?

If you have ever stayed in a hotel or an apartment, chances are that you are familiar with the small door viewer peephole located in the middle of the door allowing someone inside to see people at their door or in the hallway outside of their apartment.This simple invention has helped protect people from unwanted visitors, burglars, and other unsavory characters for decades, and now it has been improved.

The peephole camera is a much more recent improvement to home security which allows you to view or video the visitors at your door, through a camera device which can be put into the door viewer hole of your door. The peephole camera can include a large variety of features.

Motion Detection: This feature includes a motion sensor right by the camera device to start recording the moment it detects motion outside your door. This feature is nice because you don’t need to be constantly recording through your digital door viewer camera to see who has been near your doorstep recently.

Video Recording: This feature seems like a no brainer. Having a video recording would allow you to go back and view footage in the event of a house break in or if you are wondering who was the last person to open the door to your house. This feature often comes accompanied with different image and recording storage capabilities such as cloud storage or an sd card.

Recording storage: If your digital door viewer, peephole camera, has the video recording feature then it must have a way to store the video and image. This can be accomplished with a simple sd card, micro sd card, tf card, gb microsd card or through cloud storage. Some companies will give you a little bit of free cloud storage with the purchase of a digital door peephole camera with the option to purchase more storage.

Smartphone Compatibility: A higher end digital peephole viewer, aka peephole camera also has an app which will interface with your smartphone and allow you to view the video footage of your camera from wherever you are located. This is a nice feature to have because even when you aren't home you can always make sure you are secure by simply checking your mobile device.

Knocking Sensor: A knocking sensor is similar to the motion activated sensor feature on a peephole camera. In that when someone knocks on the door a vibration sensor will turn on your door peephole camera to record what is going on outside your door.

Doorbell button: This feature is also similar to a knocking sensor except that it will start recording when someone rings the doorbell. Essentially it will start making a video at the push of a button.

Screen Display: A screen display will allow you to easily view activity outside your door without having to peer through a small peephole device. When getting a screen display it will be important to investigate whether it is a tft lcd screen, an lcd display screen, a plasma screen, or a different type of screen. You should also consider what it's battery usage is, how easy it is to view from certain angles, and how easy it is to view with varied lighting.

Battery powered: We would recommend using a battery powered peephole camera for several reasons. First is the overall security. If your power goes out or worse if a burglar cuts the power to your house you will want your door peephole camera to have either back-up battery power or be completely wireless altogether. Second, Battery powered devices are easy to install. Unfortunately, a battery powered device also means that you will eventually need to change the battery so it is important to consider how easy it is to change the battery for your device, what the battery life is and whether it is a rechargeable battery or not.


2 way audio: The idea of talking through a peephole is probably pretty strange however the ability to speak into your phone and have it come across a small smart microphone in your peephole view cam can be useful if you are away from the house or if you are upstairs and don't want to talk to someone directly

Night Vision: If you have a well lit porch this feature will be pretty unnecessary. However if you have a dimly lit apartment complex hallway then it can be important to have Night vision on your cameras so it will amplify the existing light and even highlight the infrared coming off of people allowing you to view passerbys easily even in the dark.

Facial Recognition: Biometrics is of course a hot topic right now. Especially since many people have facial recognition and fingerprint scanners built into their phones. Incorporating facial recognition technology into your digital door viewer could allow you to check if your son, daughter, or neighbor has come to your door recently. It could also allow you to identify a thief depending on the viewing angle that the camera gets on the perpetrator’s face. That being said, it is important to note that as long as your peephole camera has video capabilities you can record a person's face and then plug it into a computer with facial recognition ability without having to pay for the extra feature.

What are the pros and cons of a Peephole Camera?


Easy to Install: A peephole Camera especially a battery powered wireless peephole camera should be pretty easy to install if you have an existing door viewer in your door. The caveat is of course if you have a door viewer already. If you do not then it can actually be quite difficult to install. See installation instructions below

Increased Security: Knowing who is on the other side of your door has some obvious security advantages. Being careful to not open the door to any unknown visitors or suspicious individuals can dramatically increase your safety.

Inconspicuous: A digital door viewer or peephole camera will usually go unnoticed perhaps even more so than a smart doorbell camera. If a camera can go unnoticed then that is often the best way to get good security footage.


Cost: No matter how basic your peephole camera is, it will still cost significantly more than a traditional door viewer device

Easy to Block: Similar to a smart doorbell it is pretty easy to see where the camera is and it is super easy to block the peephole no matter how smart your peephole camera is. There may be a feature to alert you if your peephole camera isn’t viewing anything.

Compatibility with other security devices: Many of the recommended peephole cameras do not integrate with other security systems making it difficult to have a seamless system.

What is the best peephole Camera?

The answer is that it depends, it depends on what features you value most and how your apartment or house is configured.

If you have a well lit porch and you aren’t concerned with having audio features to talk through we would recommend that your peephole camera be wireless, have a motion sensor, and be professionally monitored. These three features will dramatically increase your home security without busting the bank.

How do you change a peephole?

  1. First find out if it is is a threaded peephole or a slide in door viewer in your door peephole

  2. Second gently unscrew or pop out the existing peephole

  3. Insert the new door viewer or peephole camera into the existing hole and either secure it in place with a type of glue that won’t damage the paint on your door or foam out around the peephole or gently screw it in place so that it sits snugly against the door

  4. Lastly look through the camera and see if it gives you the viewing angle that you are looking for

  5. You’re all done

How does a door viewer work?

Similar to a telescope, which pulls in a far range of light and concentrates it into a small lens area, a door viewer uses a fish eye type lens to give you a wide view outside your door while only using a small hole to get the needed visibility.

Can you put a peephole in a door?

Physically, yes. You need to get a specific type of door drill bit to drill through your material but you can do it.

Legally, maybe. If you are renting it is important to check if your landlord is ok with you installing a door viewer hole.

What height do you install a peephole at?

Normally the peephole will be located in the center of the door about 4-5 ½ ‘ above the bottom of the door.

If you are installing the peephole you should install it to the height that is most convenient for you or if you are thinking ahead to future homeowners it would be important to adjust it to an average height for adults or teenagers to look through.

What is the peephole in a door called?

It can be called a peephole, a door viewer, a door eyelet. Etc.

How do I drill a hole in a metal door?

  1. Measure Measure measure. First make sure you clearly measure where you want to drill and create a perfect circle for where you want the circular drill bit to go.

  2. Ensure that you are using the right type of drill bit. It is important to make sure that your drill bit is designed to go through the material that your door is made out of whether that be metal wood or fiberglass or a different material.

  3. Carefully drill into the door while making sure to apply even pressure on the back of the drill

  4. Gently file away any burs or metal spikes that are left around the door so that your digital door viewer can easily slip into the hole and so the metal burs around the hole don’t become an eyesore on your main home entrance

  5. Now slip your peephole camera into the door

Note: You will most likely not have the correct drill bit for making a peephole and will need to consult and visit a local hardware store to purchase the right tool. It is also important to consider that it is much easier to drill a hole in your door and essentially impossible to fill in a hole for a metal door. Be careful to measure exactly where you want the hole to go.
