The traditional doorbell is a kind of security equipment in the building. The button is installed directly outside the door. When someone comes, as long as the horn is pressed, a loud reminder sound can be emitted, thereby reminding the residents to visit. However, this doorbell only intelligently transmits the information of the guests' visits, which can only serve as a notification and cannot judge the identity of the person coming.
In addition, these traditional doorbells are wired installation, the steps are very cumbersome and difficult to operate, regular maintenance also requires regular inspection of the wires under the distribution, which is both troublesome and has hidden safety risks. Later, after the upgrade of the traditional doorbell, it was combined with the cat's eye, so that not only the effect of the notification, but also the status of the people outside the door can be checked at any time. But because it is a traditional cat's eye, it is necessary to observe the cat's eye close to the portal at this time. Because the viewing angle is relatively small, the viewing range is very limited, and the safety of this cat's eye is relatively low.
Therefore, wireless video doorbells came into being. With the development of smart homes, smart video doorbells made of sturdy alloy materials can not only let the owner see the situation outside the door, but also can be realized by the function of remote control. Remote control.
For example, when someone is not at home, if someone rings the doorbell, the mobile phone will receive the pushed message, and the user can view the visitor through the mobile phone/indoor unit. The wireless video doorbell is also very convenient. If the user is not at home, the visiting guests do not have to wait outside the door.
Or, when the owner is too busy to open the door, as long as it is controlled by the mobile phone, the door can be opened without having to open the door by hand. Moreover, the wireless video doorbell adopts the relevant PIR mobile monitoring technology, which can automatically record the image of the visitor. As long as you walk into the monitoring area, the wireless video doorbell will record the portrait information. If someone tries to disassemble or destroy the doorbell, the doorbell will immediately give an alarm prompt. Very convenient and intelligent, safe and practical.
