Flask is lightweight and requires minimal setup, making it a great choice for building small to medium-sized APIs. It provides developers with a quick and easy way to create RESTful APIs that can be used by other software applications. The programe loops again and again as this flow.Python Flask is a popular framework for building web applications and APIs in Python. The system goes into motion scanning state. Until no motion anymore, the recorded videos will be pushed to mobile to confirm the motion end. After that a mount of time, if moving is still there, Pi re-capture a new image and send a new notification. At the same time, Pi keeps recording the moment for a few more seconds. If moving happens, The Pi will capture a still image and send notification to phone immediately. When the script launch, it takes 2 seconds to warm up the camera to make sure everything works properly. It means you can send a command from mobile or web to Raspberry Pi for particular action such as (for instantly take a photo) or (to get current system information of Pi). (1) RaspberryPi&Camera module as the data source that continuously scan for motion and recording video at the same time, (2) PushBullet as the message-broker to send messages(text, still image, and videos) back and forth between RaspberryPi and Mobile/Web, and (3) mobile/web acts as “notifyee” who receives the still image and video of motion. There are 3 actors play together to build up the application. You will have a clear vision about what application does. This section explains the specification of application including app structure, and general flow chart.
