Build Your Own DVR With Live Streaming Capabilities With Raspberry Pi
We’ve already seen the Raspberry Pi used as a DVR before , but at PubNub they used the same concept but also had live streaming capability provided you can set up a hotspot on your smartphone.
The camera here uses Node.js to set it up, then takes a picture every few seconds and saves it online using your smartphone’s hotspot. Thus, the broadcast will be available online at any time. To do this, you’ll need a Raspberry Pi and a camera module, as well as some sort of network access. It is also a fairly straightforward process to set up the camera itself. When you’re done with that, you’ll create a viewer so you can actually see all of these streaming images. This project uses the PubNub app framework, but you can run this project using a free account. Go to PubNub for the complete guide.
