The video doorbell is a device made with convenience in mind. For Video Doorbell, there are two main end-users. These end-users are the owner and the visitor. The usage of a camera and Wi-Fi makes it possible for the owner to answer the door even if they are not at home. When a visitor presses the doorbell button the visitor may view and talk to the guest if they choose. The camera saves a picture of the visitor when they press the button. If the owner chooses, they can also save a video of the conversation with the user. The owner can then later view or delete the picture/video if they choose.
The purpose of this document is to define the specifications of the hardware and software. This document specifies the design of the hardware/software and the flow of the data involved. This document gives the development team the ability to minimize any issues that could occur in further steps of the project. To be able to make a Raspberry Pi and the software work together requires constraints on many things. These contraints include: time and cost, as well as hardware and software limitations based on the aforementioned constraints. To have a complete product within the time frame many hours will go into the hardware and software portions of the product. Many separate moving pieces and parts will come together to form our complete product.
