Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an external door bell apparatus and a visitor identification system using a wireless Wi-

The present invention relates to an external door bell apparatus, a visitor identification system including the door bell system, and a visitor identification method using the same. More specifically, the external door bell apparatus transmits a visitor's voice or image through wireless Wi- And a visitor identification system that allows the user to check the phone number.

In the past, if a visitor is confirmed to be a member by pushing an outer door bell to a house that is not in the house, it often leads to a theft or the like.

The outer door bell is a useful device for the user to confirm the outside visitor through voice or image in the house, but there is also a side effect that sometimes it is confirmed that it is absent.

Therefore, the number of technologies for connecting a smartphone and allowing a user to check the voice and image of a visitor through a smartphone and to communicate with a visitor are increasing.

Since the visitor can communicate with the user in real time through the door bell, the user can be recognized as if he is at home. In addition, as a user, it is possible to rest assured that the person who visits during the absence can directly check and take measures.

Conventionally, external door bells and smart phones are connected in various ways.

For example, in order to connect an external door bell to a smart phone, a 3G / 4G mobile communication module may be directly attached to an external door bell or an inner door phone to allow communication through a mobile communication channel. In this case, the unit price of the outer door bell is increased and the maintenance cost is increased. In addition, when the 3G / 4G mobile communication module is mounted on the outer door bell, it is disadvantageous in that it can be destroyed intentionally from the outside.

As another example, Patent Publication No. 10-1110893 discloses a technique for connecting an internal door phone connected to an external door bell to the Internet. The internal door phone is configured to be connected to the server of the provider providing the visitor verification service through the Internet. Then, the server stores and manages the visitor voice or image of the external door bell, and transmits the voice or image to the smart phone of the user registered in advance via the Internet. In addition, it is configured to transmit a voice of a user's smartphone to an external door bell and to conduct a real-time conversation with a visitor. The server must have session establishment and maintenance functions between the external door bell and the smartphone.

In this case, there is a disadvantage that a separate server for the visitor identification service should be provided, and the home door phone in the home should be installed again in each home. In addition, there is a disadvantage that service maintenance costs required for session setting and video storage management are continuously generated.

On the other hand, as another example, JP-A 2002-0093189 uses a set-top box for home automation instead of such a server. Especially, recently, the development and supply of technology for home automation function is increasing. The set-top box is connected to the Internet, and has a merit that the user can perform various remote control from the outside in connection with the user's smartphone.

However, the penetration rate of home automation is still low and the construction cost of home automation is still low. Assuming home automation is implemented, it would be advantageous to use it, but if it is merely for external visitor identification, it is costly to spend some functions in home automation.

As described above, the conventional visitor identification techniques have various disadvantages in the construction itself and require a lot of equipment construction and cost.

Therefore, it is required that all households can use Visitor Identification Service with minimum cost and simple technical structure.

No. 2002-0093189 No. 10-1110893
