Traditional wireless doorbells are installed directly beside the door. When visitors come, they can can press the button and make a call to alert house owners. However, this doorbells only notifies that there is a visitor; and can not tell who the visitor is.
In addition, these traditional doorbells require wired installation with difficult and complicated operation.
Besides regular maintenance requires checking all wirings timely, which is troublesome with potential safety risks.
Afterwards, after update, the traditional doorbell was combined with door peephole. This not only alerts the visitor's coming but also check who is outside the door. However, because it is a traditional door eye camera, users need to get close to the door viewer to see the visitor. Because of its small view angle, safety of this door viewer camera is relatively low.
Therefore, the wireless video door phone came into being. With the development of smart home technology, the smart video doorbell not only help the owner see the situation outside the door, but also realize remote control.
For example, if someone is not at home, if someone rings the doorbell, then mobile phone will receive the push notification, and the user can view the visitor through the mobile phone or indoor unit. Even if the owner is not at home, he/she can have video intercom with visitor.
Or, when the owner is very busy and has no time to open the door, unlock can be done via mobile phone. Moreover, PIR motion detection can automatically snap the images of the visitors as soon as they enter monitoring scope. If someone tries to disassemble or destroy the doorbell, the camera will immediately give an alarm. It is very convenient and intelligent, safe and practical.
Time goes forward, Technology makes progress. We believe that human beings will make better and better smart products in the future.
