| # Mobile Deployable Smart Doorbell Team Members: - Ricky Chen (pohsuhc2) - Charles Lai (jiayeyl2) - Victor Lu (vclu2) # Problem: As a college student living in a dorm/apartment complex, the absence of a doorbell poses an inconvenience for both myself and my visitors, such as my friends, neighbors, or anyone who would come to my house. My room is located far from the entrance; therefore, every time they knock on the door, I can’t respond promptly. Moreover, regular doorbells will fail to notify me if I am either too far from the door or there are barriers between. # Solution: Our project is a small, smart doorbell that can be easily deployed and notify the resident via their phone. The doorbell will be connected to the internet and to the resident’s phone. When a visitor presses the doorbell, the resident will be notified via phone, which is almost always with the resident in this technological society. Therefore, the resident can be notified in real-time regardless of where they are. Furthermore, our doorbell will support a variety of features, such as voicemail and video recording. The resident can respond to their visitors despite not being at home and in many different circumstances. # Solution Components **Subsystem 1 - Camera** This project will contain a built-in camera enclosed within the package. This camera will record everything outside the apartment real-time and upload these video data to the mobile app. The camera will automatically take a picture whenever the button is pressed. With this feature, the user will be able to be alerted immediately when someone is outside the apartment. Moreover, the user will also be able to identify the visitor with the photo taken by the camera. **Subsystem 2 - Internet Connection** We will connect our device to the internet, so all the data collected in the doorbell will be sent to the users’ phones. One feature we want to achieve is the property owner can listen to and watch the person answering the door in real-time, in other words making a video call but only the phone user can see the other person. Therefore, we will have to send both video and audio data from the doorbell to users’ phones. **Subsystem 3 - Phone App** In order to offer users the best experience, this project will also include a mobile application. Once the module is deployed onto the user’s door, the user can utilize the phone app to receive eminent information regarding the situation outside the apartment. Moreover, the user can also monitor his or her house everywhere in the world with internet connection, further ensuring the safety of the apartment. **Subsystem 4 - Audio Transmission** Since we want the property owner and the person answering the door to talk with each other, we will deploy a microphone and a speaker in the doorbell. The microphone will get the audio data from the person answering the door, and the speaker will play audio from the phone’s app from the property owner. On top of this, we will also have to access audio components in a phone, so that we can make sure the microphone and speaker on both sides can receive and play data. **Subsystem 5 - Power** The battery of the doorbell has to support several modules, including a camera, internet connecting system, microphone, mini speaker, and the PCB itself. We want to make sure that it has enough power so that the user doesn’t have to constantly refresh the battery. Additionally, for the sake of convenience, we also make the doorbell powered with dry cells so that the users don’t have to wait and charge the batteries. **Subsystem 6 - Button** There will be a button in addition to all the other features within this project. When this button is pressed, the microphone embedded inside the doorbell will start recording the surrounding voice. When the button is released, the recording will stop and the whole audio data will be uploaded to the user’s mobile device. Thus, the visitor can leave a voice message even if the user is not home at the moment. Furthermore, the button will also send a notification to the user once it is pressed, informing the user that someone is waiting for him or her at the doorstep. **Subsystem 7 - Deployment Device** We will make our device as light as possible so that it can be stuck on a door. The backside of the doorbell will be a side of velcro tape to make it easy to install and remove. Users can easily buy Velcro tapes anywhere, so it will be convenient if they have to move to another place or replace Velcro tapes.

Thus, even customers who are not familiar with technology can use this product easily. - Data Transmission: The module will need to enable a smooth transmission of visual data from the doorbell to the application. It also will have to allow simultaneous transmission and reception of audio data to and from the mobile device. - Low Power Consumption As the module will be running on battery, we need to make sure that the power consumption of the device is low enough to sustain a long period of continuous operation. - Simple Setup Procedure The setup procedure needs to be simple but robust. Thus, the product can be deployed on almost every door. |
