Does a smart door lock support real-time monitoring of outside activity on the indoor screen, combined with video intercom functionality?

With the rapid development of smart homes, door locks are no longer simply a physical protection tool; they have evolved into a core gateway to home security and intelligent interaction. Traditional mechanical locks or basic electronic locks offer only simple opening and closing functions, leaving users unable to monitor real-time activity outside the door. This "blind spot" creates numerous inconveniences and safety risks, especially for those living alone, those with elderly or children, or those who frequently receive visitors. Modern, high-end smart door locks, however, have revolutionized this situation by integrating indoor high-definition displays with video intercom functionality, truly enabling a smart security experience where you can "see who's there before you open the door."When a visitor presses the doorbell or pauses at the door, the smart door lock's external wide-angle camera instantly activates, transmitting a clear, real-time video feed of the outside to the indoor display. Whether it's a delivery, a friend or family member visiting, or a stranger lingering, users can clearly see what's happening outside the door through the indoor display without opening the door. This visual monitoring not only enhances a sense of security but also empowers users to make informed decisions. For example, when a courier is seen standing at the door, a voice prompt can be remotely activated, "Please leave at the door," avoiding the inconvenience of frequent door openings. If a suspicious individual is spotted lingering, an alarm recording can be immediately activated or the management office can be notified to prevent potential incidents.The addition of a video intercom function further enhances the convenience and user-friendliness of interactions. Users can conduct two-way voice conversations with visitors through the indoor screen without having to approach the door, with clear audio and minimal latency. This feature is particularly valuable for hearing-impaired seniors or family members with limited mobility. They can view incoming visitors from the sofa and confirm their identities through voice communication, avoiding the risk of missing important visitors due to poor vision or hearing. Furthermore, indoor screens typically feature high-brightness backlighting and wide-viewing angle display technology, ensuring clear viewing even in bright or dim lighting, ensuring worry-free use around the clock.Furthermore, smart door locks' visual systems often incorporate AI-powered human detection and motion tracking. When someone moves near the door, the camera automatically captures and tracks their movements, continuously recording their movements even if they briefly leave the camera's range. Some high-end models also support facial recognition. If the system identifies a family member or authorized person, it automatically sends a notification, "Dad has arrived home." If the face is unfamiliar, it is marked as "Unknown Visitor" and an alert is sent to the mobile app, providing intelligent, tiered alerts.From a privacy perspective, the design of the indoor screen avoids the awkward and unsafe practice of frequently peeping through peek holes or door cracks. Traditional peek holes have a narrow field of view and require close observation, which can easily expose the indoor environment. Smart door locks, on the other hand, typically feature an indoor screen prominently located in the living room or entryway, allowing users to remotely and securely monitor what's happening outside, protecting privacy and enhancing user dignity.Furthermore, video intercom systems are often deeply integrated with mobile apps. Even when users are away from home, they can remotely view real-time footage, receive alerts, communicate with visitors, and even unlock their door with a single click (requiring multiple verifications for security). This ability to stay informed of home security at any time and from anywhere greatly enhances modern people's sense of control over their home security.In summary, the smart door lock, which enables real-time viewing of outside activity on the indoor screen and incorporates video intercom functionality, has transcended traditional security to become a crucial sensor node in the smart home. It leverages the power of technology to eliminate the "visual blind spot" at the door, ensuring every entry and exit is based on knowledge and trust. In today's world of pursuit of safety, convenience, and quality of life, such a smart door lock is not only a guardian of the home but also an intelligent eye connecting the inside and outside worlds.
