May 31, 2022

A few decades ago, unlike many high-rise buildings today, many people lived in bungalows. Guests came and banged and knocked on several doors. The owner could hear them at home. Later, more and more residential buildings, people have installed anti-theft doors, wall sound insulation is also good, knock on the door can not hear, and electronic doorbell was born. In general, two AA batteries were placed. After the trigger button outside the door was pressed, the "doorbell" in the door rang a few times. There is also a piece of electronic music played by the IC chip. Later, as people’s safety awareness became stronger and stronger, guests were not allowed to enter the building without permission, and they needed to speak with the owner of the stairs upstairs before they could open the door. The tool that can achieve this kind of behavior is the visual doorbell.

Video doorbell, English name is Video door phone or Video door bell.

The video doorbell system is a device used in high-rise residential buildings, inside and outside apartment buildings, household information transmission, anti-theft door control and in case of emergency the tenants alarm to the building duty room. It is fully functional, reliable, its large capacity, beautiful appearance, easy installation and use and welcomed by the majority of users, and has also been widely used in safe living quarters.

The resident hears the ring tone and, like answering the videophone, accepts the visitor's call through the downstairs doorway host to conduct a dialogue. At the same time, the visual extension at the household can receive the video image through the downstairs host camera, and the tenant observes the extension on the display screen. The monitoring image confirms the identity of the visitor, and finally decides whether to press the unlock button of the indoor extension to open the electronically controlled door lock connecting the host computer, allowing the visitor to open the door to enter.

The video doorbell intercom system will be the basic configuration of the intelligent building community. In the newly-built commercial housing design, some cities have been forced to implement it. At the same time, as the market continues to expand, there are many manufacturers of building intercom products, and the capabilities of manufacturers involved in the industry are uneven, so the market competition will be very fierce. To survive, we must develop. Therefore, the continuous improvement of technology and the continuous introduction of new technologies will make product features more diversified, and the cost will be further reduced, which will continue to expand the visual doorbell market.
