Smart doorbell cameras are one of the most popular types of security devices that let homeowners know who is at the door via smartphone. However, a question that may be on the mind of many consumers is do doorbell cameras record continuously. So now let's better understand the concept of doorbell cameras and how they decide whether and when they are capturing video.

What Are Doorbell Cameras?

A doorbell camera is a video camera that is installed by the door of the house either as a wired camera or a rechargeable camera. It is a doorbell that also comes with a security camera and you can see and speak with anyone at your door from your phone even if you are not at home. If someone enters the area of the doorbell, the camera will give a smartphone notification and you can see the live video stream no matter where you are.

Others such as the Ring Video Doorbell record when the button is pressed or when it detects motion. Some like the Nest Hello doorbell camera offer round-the-clock continuous video recording for a price. Almost all modern doorbell cameras are also compatible with smart home ecosystems such as Amazon Alexa.

That begs the question, do they record all the time?

In general, most doorbell cameras only capture video when the doorbell is rung or when motion is sensed within the camera range. The video clip time can vary anywhere from a few seconds up to a minute on average. This helps save space and data usage on the applications being used in the process. However, technology and capabilities are not stagnant here with some of the high-end models offering continuous 24/7 recording.

That determines when and how much doorbell cameras record: 

  • Doorbell Button Pressed  All doorbell cameras will start recording the moment the physical doorbell button is pressed. It is usually less than one minute long in most of the models as these clips are normally very short.
  • Motion Sensor Detection - Doorbell cameras have motion sensors to sense when someone is approaching your door. When they cross this point, the camera will start recording even if they do not go further and ring the doorbell. In general, clips may be limited and may range from 10 to 60 seconds if triggered by motion only.
  • Subscription Options  Most of the Nest Hello models come at a higher price tag, but they come with the added functionality of continuous video recording if you pay for the monthly cloud storage. This means every time a person comes or whenever something occurs, the camera will record the whole event with no interruption.
  • Recording options - Most of the doorbell cameras are designed to be customizable in terms of settings such as motion detection range and number of recorded videos in a given time. Therefore, the amount each model records can vary depending on directions.
  • Recording Limit  Recording with local storage and recording with cloud storage differ and affect the recording limit. Storage capacity at the local level is limited while recording duration in the cloud can vary depending on the amounts subscribed to.
  • Flexible Recording Options  You can adjust parameters such as the detection zone of the motion sensor and the number of minutes of video to record in the settings of most doorbell cameras. Thus, the amount each model records can vary based on directions.
  • Local Storage vs Cloud Storage  Storing recordings locally vs backing up recordings to the cloud affects recording capacity. Local storage is limited while cloud-based recording time is limited by subscription plan amounts.

Why do doorbell cameras just record everything?

Given that security is one of the primary functions of these doorbell cameras, people may ask why most do not record continuously rather than record short videos only. There are a few core reasons: There are a few core reasons:

  • Bandwidth Usage  This involves streaming high-definition videos for a whole day, which is very likely to exceed the bandwidth limit provided by most consumer internet plans. The bandwidth cost would be expensive. Sustaining smooth streaming also entails having a powerful consistent bandwidth, which may not be obtainable in all the neighborhoods.
  • Privacy Issues  Advocates for privacy argue that constant recording of an individualâ front door is a violation of civil liberties and the right to privacy if not well done. What makes doorbell cameras unique is that they exist in a middle ground where they can provide security and require no worries of being turned into a surveillance state.
  • Storage Demands - With high-quality HD video, one is bound to use a lot of storage space. Recording everything would create a massive amount of footage that would require storage space and management. Backup, on the other hand, would be equally challenging. Consumers do not have enterprise-level NAS solutions as they do not have enterprise-level network-attached storage systems. Hence the availability of short relevant clips is more useful.
  • Power Consumption The constant streaming of 24/7 video also poses a huge load on the camera battery and electricity. Another disadvantage of a doorbell camera is that it would be nearly impossible to have constant power and charge it whenever necessary. Short recordings allow for the longer duration of battery or low voltage wiring.

The deeper reasons are related to bandwidth, privacy issues, storage, and power requirements from always recording from a consumer device. It is possible that as the internet and battery technology improves, always-on recording features may transition to being more commonplace. However, for now, triggered recording based on an activity is the most suitable for doorbell cameras in homes.

Should I get a doorbell camera that records 24/7?

However, if having a complete record of everything that happens at your front door is a priority, then going with one of the doorbell cameras that offers continuous recording is advised. Just ensure that you are willing to pay a monthly subscription fee for adequate cloud storage for the retention of all the videos for future use when necessary. As we shall see, continuous recording eliminates any chances of missing some event of interest since it happens between motion-triggered clips. But what should be remembered is that for most homeowners more occasional recording is sufficient to secure the house at a lower cost. Consider what you will require and how much you are willing to spend when deciding between models that record only sometimes against those that advocate for full-time recording.
