[0001] The subject matter in general relates to access control systems. More particularly, but not exclusively, the subject matter relates to a smart doorbell.
Discussion of related art:
[0002] Generally, doorbells are used by visitors to indicate the residents of their arrival. Such doorbells usually make some type of sound when a visitor rings the doorbell. In most cases, the sounds produced are loud in order to efficiently notify the residents about the visitor at the door. More often than not, such doorbells act as a source of unwanted disturbance to the residents, especially to elderly people or infants sleeping at home. Adding to it are local children who play around ringing resident’s doorbells, and sales agents.
[0003] One conventional system tried to address this problem by using a password based doorbell, where the resident is allowed to assign a unique password and ringtone for every expected visitor. Thereafter, when the visitor inputs the unique password, a ringtone associated with the password is played, thereby allowing the resident to identify the visitor at the door and also stopping others from ringing the doorbell. However, such systems introduce new problems to the residents as they have to manually alter the password every time a new visitor is expected. Further, the password remains active until the resident manually deletes it. Additionally, it is next to impossible for any resident to identify a large number of visitors based on ringtones.
[0004] Such conventional systems usually have a limit to the number of passwords that can be assigned at a given time, thus making it more annoying for the residents to go through the entire process of deleting some old visitor’s password and creating a new password for the revisiting visitor.
[0005] Conventional security systems use video cameras, bio-metric identification and RFID cards among other means to open a door. However, none of these provide a reasonable solution to overcome the above stated drawbacks of doorbell. Further, such security systems are generally installed at the entry point of the gated communities, campuses, and apartments, among other closed enclaves. Thereby, the systems are again vulnerable to all the above mentioned drawbacks of existing doorbells since a person who enters the closed enclave can ring any resident’s doorbell.
[0006] In view of the foregoing discussion, there is a need for an improved doorbell to overcome the above problems while improving resident’s security and privacy.

SUMMARY
[0007] Accordingly, an improved technique to overcome the above problems is needed. To fulfil this need, a system and method for a smart doorbell is provided. In an embodiment, the smart doorbell may comprise of one or more circuits configured to receive a password from a visitor, validate the password and identify the visitor based on the received password by communicating with a server. Further, the server may be configured to ring the smart doorbell in case the identified visitor is authorized by a resident associated with the smart doorbell.
[0008] In an embodiment, the resident may use a mobile device to share information of the visitor with the server, which is configured to generate and share the password with the visitor.
[0009] In an embodiment, a notification may be sent by the server to a mobile device of the resident in case the identified visitor is authorized by the resident. The notification may include one or more details of the visitor.
[0010] In an embodiment, the password may be randomly generated by the server computer and may be valid for a predetermined time.
[0011] In an embodiment, the one or more circuits may be configured to refrain the smart doorbell from ringing in case the identified visitor is not authorized by the resident.
[0012] In an embodiment, the server may be configured to send an alert to one or more security personnel and/or security agencies in case the identified visitor is not authorized by the resident.

[0067] FIG. 5 depicts a flowchart of an exemplary method 500 for operating the smart doorbell 102, in accordance with an embodiment. At step 502, information about one or more expected visitors may be received by the server 106 from the resident’s mobile device 108 of a resident. Additionally, the received information may also include the expected time of visit, duration of stay, nature of visit, and frequency of visit, among other information. Further, at step 504, the received information may be analyzed by the server 106 and thereafter a password may be generated for each of the visitors, where the validity of the generated password may vary based on the received information.
[0068] In an embodiment, the generated password may be used for a pre-determined number of times, where the pre-determined number is based on the information received from the resident. Alternatively, the generated password may be a One-Time-Password (OTP).
[0069] Further, the generated password may be shared by the server 106 with the visitors via the visitor’s mobile device 110. At step 506, the generated password may be received via the smart doorbell 102 from the visitor. The received password may be communicated to the server 106 by the smart doorbell 102. Further, at step 508 the password’s validity may be checked by the server 106 by comparing it with data stored in the server 106 in order to identify the visitor and determine whether the identified visitor is an expected visitor for the resident’s house.
[0070] In an embodiment, the identity of the visitor may be determined by the server 106 based on the entered password. Additionally, the data received from the camera 204 and the biometric scanner 206 may also be used to identify the visitor at the door.
[0071] In case the entered password is determined to be invalid, the server 106 may check whether a list of predefined rules is satisfied. In case the list of predefined rules is not found to be satisfied, the server 106 may wait for a predetermined period of time to receive the correct password from the visitor through the smart doorbell 102, beyond which the server 106 may raise an alert to notify one or more security personnel or security agencies about the suspicious behavior of the visitor.
[0072] Further, at step 510, in case the received password is valid and the visitor is identified, the smart doorbell 102 may ring. Simultaneously, a notification may be sent to the resident’s mobile device 108 with details of the visitor at the door.
[0073] In an embodiment, the resident may be allowed to configure the smart doorbell 102 for “Do not disturb” mode. In such a case, the smart doorbell 102 may refrain from ringing even if the visitor password is valid, instead a notification may be sent to the resident’s mobile device 108 based on which the resident will be made aware of the visitor’s arrival.
[0074] In an embodiment, in case of a closed enclave with multiple houses equipped with smart doorbells 102, it is possible for a visitor to enter the generated password at a wrong smart doorbell 102. In such a scenario, the wrong smart doorbell 102 may refrain from ringing, and further the server 106 may identify the visitor based on the received password and notify the correct resident who invited the visitor about the incident. Additionally, a message may be displayed on the display 202 of the wrong smart doorbell 102 to inform the visitor that he/she is at the wrong house, and needs to go to the correct house.
[0075] FIG. 6A illustrates an exemplary user interface 602 on the resident’s mobile device 108, in accordance with an embodiment. The entry management module 316 may provide a user interface 602 as shown in FIG. 6A. Further, the resident “Arun” using the resident’s mobile device 108 may choose the option “Invite a friend” to invite a friend to his residence. Arun may also choose “Invite a service provider” option to authorize entry for regular visitors such as servants and other such regular visitors. The ‘Do not disturb’ option may be used in case Arun does not wish to be disturbed.
[0076] Additionally, Arun may be able to block a visitor invited by other residents in his house using “Block visitor” option. Also, ‘View visitor log’ option may be used to keep track of visitors and their visits.
[0077] In case Arun chooses ‘Invite a friend’ option to invite a friend, the user interface 602 may show an option as depicted in FIG. 6B, where Arun may choose between an option to add a new visitor or choose an existing visitor. In case the ‘Add visitor’ option is chosen by Arun, the entry management module 316 may seek the visitors details through the user interface 602 as shown in FIG. 6C. Further, the visitor details may be entered into the entry management module 316. In case the ‘Choose an existing visitor’ option is chosen in FIG. 6B, a visitor whose details are already stored in the entry management module 316 may be selected from a list of visitors.
[0078] Arun may click on the ‘Add visitor’ and a window as depicted in FIG 6C may open on his resident’s mobile device 108. Here, Arun may input details related to the visitor “Vishal” such as his name, mobile number, date and time of visit and information about the visitor as shown in FIG. 6C.
[0079] Subsequently, the server 106 may generate a password, and communicate the invite to Vishal’s mobile device 110 as depicted in FIG. 6D. Further details may also be included in the message such as the date and time of the visit, and Arun’s house address, among others.
[0080] Vishal may visit Arun’s house and input the received password into the smart doorbell 102 as depicted in FIG. 2. Subsequently, the server 106 may validate the password to identify Vishal. Further, Arun may receive a notification regarding Vishal’s visit on his resident’s mobile device 108 as depicted in FIG 6E.
