What Is a Video Doorbell?

A video doorbell is an outdoor camera mounted on or near your front door. It can be powered by a battery or hardwired into an already existing doorbell and chime. What makes video doorbells so valuable are their capabilities—and how they work. First, they generally feature a high-definition 1080p camera, a buzzer, and two-way audio. All of these features connect to your smartphone or another smart device via a smart app. That means you’ll get a notice on your mobile app when someone pushes the doorbell. A notice will also reach you as soon as the camera detects movement or a person. This depends on if (and how) an AI has been implemented.

  • They can move freely around the home and are easy to operate.
  • They are limited to 2.4G transmission distance which can only be most effective in buildings with up to three floors.
  • The 2.4 GHz band provides coverage at a longer range but transmits data at slower speeds. it’s also more prone to interference.
  • There might be a challenge with battery life; hence, the need to change batteries frequently if the doorbell camera is not rechargeable.

This will help make it possible for the camera to use data from cellular towers which is not the case with Wi-Fi. However, this particular option is generally available only for larger security systems.


The features of video doorbells include:

1. Motion Detection

One of the most important sensors is the passive infrared sensor that detects motion for people or objects within view. Video doorbells often pair with mobile devices and the manufacturer’s app to provide notifications; hence, once motion has been detected using the video doorbell’s sensor, you’ll receive a mobile notification. Some doorbells allow you to control how sensitive the PIR sensor is to objects at your door to determine whether or not you receive a notification.

Ensure that your doorbell has infrared so that it can work during the day and night. Viewing angles are varied, but they range between 150–160 degrees. Even so, you can opt for a doorbell camera with a 180 degrees field of view. Besides, you may enhance the angle using a wedge or corner kit in order to protect your doorway from suitable angles.

3. Two-way communication

Doorbell cameras have in-built microphones and speakers. These features enable you to undertake a two-way conversation, whether inside or away from your house.

Uploaded videos can be stored for a week or a month before being deleted depending on the cloud server. This allows you to review movements around your home even when you weren’t available when the movements were detected by the doorbell camera.
