How to improve a security camera with Intel IoT Gateway

First of all you need a webcam UVC compliant as this Logitech* C270 Webcam with HD 720P resolution and 2.4 GHz Intel® Core™ 2 Duo processor. The webcam plugs into the USB port of Intel® Edison development board which turns it into an IP webcam streaming video to a website. Using the webcam with the Intel® Edison development board allows for the camera ‘sensor’ to be easily propagated to different locations around a home. The Intel® IoT Gateway captures images from the stream and uses OpenCV to analyze them. If the algorithms detect that there is a face or a person in view, it uploads the image to Twitter*.

The Intel® Edison development board continuously stream a feed that the Gateway could capture from at any time. This was accomplished using the mjpeg-streamer library.

The brains of the whole security camera is on the Gateway. OpenCV was installed into a virtual Python* environment to create a clean and segmented environment for OpenCV and not interfere with the Gateway’s Python version and packages.

To quickly create a program and connect a large number of capabilities and services together as with this project, Node-RED* was used. Node-RED* is a quick prototyping tool that allows the user to visually wire together hardware devices, APIs, and various services. It also comes pre-installed on the Gateway. Make sure to update to the latest version.

The “http request” node sends a GET message to the IP webcam’s snapshot URL. If it is successful, the flow saves the image. Otherwise, it tweets an error message about the webcam.
