Introduction: With the rapid advancement of technology, smart wireless video doorbells are becoming an increasingly important component of modern home security systems. This article will delve into the various components and functions of smart wireless video doorbells, from the doorbell door unit, indoor unit, camera, display screen, touch screen to battery or power supply, analyzing their principles, advantages, disadvantages, and application scenarios, to provide readers with a comprehensive understanding of how smart doorbell systems operate and their future development trends.

Doorbell Door Unit:

The doorbell door unit is one of the core components of a smart wireless video doorbell system, typically installed outside the door. It includes a camera, a touch screen, a microphone, a speaker, and a button. The camera is responsible for capturing the outdoor scene, the touch screen is used for user operation and settings, the microphone receives sound, the speaker plays sound or intercom, and the button triggers the doorbell or other functions.

Example: For example, when a stranger approaches the door, the high-definition camera of the doorbell door unit can capture their image in real-time. Through the touch screen and speaker, residents can engage in two-way communication, enabling them to understand the identity and intentions of the visitor, thus ensuring home security.

Indoor Unit:

The indoor unit is another important component of the doorbell system, usually installed inside residents' homes. It includes a display screen, a microphone, a speaker, and a set of buttons or a touch screen. The display screen is used to show the real-time outdoor scene, the microphone receives sound, the speaker plays sound or intercom, and the buttons or touch screen are used for user operation and settings.

Example: When the doorbell rings, the display screen of the indoor unit will instantly show the outdoor situation. Residents can choose whether to enable the intercom function through the touch screen or buttons, facilitating immediate interaction with the visitor.

Camera:

The camera serves as the core visual sensor of the doorbell system, responsible for capturing the outdoor scene. Modern doorbell systems are typically equipped with high-definition cameras and wide-angle lenses to ensure clear images and a broad field of view.

Example: For instance, when someone is delivering a package or visiting the door, the camera of the doorbell system can accurately capture their identity and actions, providing residents with timely monitoring and security assurance.

Display Screen:

The indoor unit is usually equipped with a display screen for showing the real-time outdoor scene. These display screens are typically LCD or LED screens with high resolution and good visual effects, ensuring clear display of the outdoor scene.

Example: Residents can clearly observe the outdoor situation through the display screen of the indoor unit, understanding the identity and intentions of the visitor, and making corresponding decisions.

Touch Screen:

The touch screen is an essential component of both the doorbell door unit and the indoor unit, used for user operation and settings. It can be a surface acoustic wave touch screen or a projected capacitive touch screen, characterized by high sensitivity and rapid response.

Example: Through the touch screen, residents can conveniently set various parameters of the doorbell system, such as intercom volume, video recording, etc., to meet their personalized needs.

Battery or Power Supply:

Smart wireless video doorbells typically use batteries or external power sources for power supply. The battery is usually installed inside the doorbell door unit or indoor unit to provide power, while the external power source is connected to the doorbell door unit or indoor unit through a power adapter to maintain continuous power supply.

Example: The battery power supply mode of the doorbell system enables normal operation even in the event of a power outage, providing residents with continuous security assurance.

Conclusion:

Smart wireless video doorbells, through components such as the doorbell door unit, indoor unit, camera, display screen, touch screen, and power supply, achieve comprehensive access control monitoring and security protection functions. With the continuous development of smart technology, smart doorbell systems will be continuously upgraded and improved, creating a safer and more convenient home experience for users.
