With the continuous advancement of technology, smart home products play an increasingly important role in enhancing home security and convenience. The smart doorbell intercom, as a crucial component of smart homes, is equipped with advanced features such as infrared night vision technology and night vision light source, providing users with convenient security measures during nighttime. This article will delve into the working principles of infrared night vision technology and night vision light source in smart doorbell intercoms, their role in enhancing security and user experience, and prospects for future development.

Infrared Night Vision Technology:

The smart doorbell intercom is equipped with advanced infrared night vision technology, allowing it to capture clear black and white images in low-light or completely dark environments. This technology utilizes infrared light sources to emit infrared rays, which are then received by the camera, converted into image signals, and transmitted to the monitor or mobile application. Due to the longer wavelength of infrared light, it can penetrate most environments at night, enabling the doorbell intercom to function effectively for nighttime surveillance.

Night Vision Light Source:

The smart doorbell intercom uses an 850nm infrared lamp as its night vision light source. This type of infrared light wavelength is invisible to the human eye, thus causing no interference when used at night. The infrared lamp works by emitting infrared light to provide supplementary illumination, allowing the camera to capture clear images even in low-light conditions. It ensures that the doorbell intercom can capture detailed and stable images, thereby ensuring home security.

24-Hour Real-Time Monitoring Function:

The smart doorbell intercom features a 24-hour real-time monitoring function, allowing users to monitor the situation outside their homes at any time. The working principle is that the camera of the doorbell intercom transmits real-time images to the indoor monitor or mobile application through network connection. This function enables users to have constant awareness of the situation outside their homes, thereby enhancing home security.

Example Illustration:

For instance, when a stranger approaches the user's door, the infrared night vision technology and night vision light source of the smart doorbell intercom will automatically activate. Even in pitch-dark conditions, the doorbell intercom can capture clear images, allowing users to view the visitor's situation in real-time through the indoor monitor or mobile application. When users are out during the day, the 24-hour real-time monitoring function of the smart doorbell intercom can capture real-time images of the surroundings and transmit them to the user's mobile application. Users can promptly assess visitors or any unusual situations, ensuring home security.

Future Prospects:

With the continuous innovation of smart technology, smart doorbell intercoms will have broader development prospects in the future. They may integrate more advanced technologies such as artificial intelligence and facial recognition to further enhance security and convenience. Moreover, as smart homes become more prevalent and sophisticated, doorbell intercoms will become an indispensable part of smart home systems, interacting with other devices to provide users with smarter and safer home experiences.


Infrared night vision technology and night vision light source are essential features of smart doorbell intercoms, providing reliable security measures during nighttime. Through the optimization of these technologies, smart doorbell intercoms serve as important guardians of home security, creating a safe and convenient home environment for users. In the future, with the advancement and application of technology, smart doorbell intercoms will play an increasingly significant role in enhancing home security and convenience.
