RTSP: Most IP cameras, regardless of the brand name (or lack thereof), use a fairly standard protocol to transmit their video stream over the network. It also provides a web server engine to serve pages quickly and efficiently. What’s even better about Node.js is there’s a fully functional library that provides easy access to the GPIO. It has seen a huge increase in popularity recently, allowing you to run JavaScript server-side, which was traditionally used for web browsers client-side. NODE.JS: Node.js is a powerful open-source, cross-platform JavaScript run-time environment. It is possible to get our system here running on the default RPi operating system, but this is just as easy to install and includes FFMPEG (more on that below). ![]() Once installed it has full support for the RPi camera, GPIO, all within a native Linux environment. While not specifically designed for RPi, they have a ready-to-roll disk image, so it installs almost as easily as NOOBS does. UBUNTU MATE: Ubuntu MATE leverages the power of Ubuntu, which is an open-source Linux distribution, with the lightweight and intuitive MATE desktop. A Raspberry Pi probably isn’t a new concept to you, so we’ll just cover the ones that might not be familiar. There are several technologies being used all together, here. Even an old PC will do the job (but you may need to setup an Arduino or small device to handle hardware triggering). It should probably also be noted that while we’re using RPi here, you could use just about any single-board computer that you can install Ubuntu on. There’s relatively little hardware required to provide a working system. For that reason, there’s some more setup involved. There are various technologies being used here, and this system is a little more advanced than a basic RPi project. The best thing is, using the GPIO interface on the RPi, you can trigger recording easily from just about any hardware interface. We can use open source software to read the video stream and save it to disk. Sure, you could use the software that came with your IP camera to do the same, but that’s not terribly efficient for your own computer, especially when it runs slowly as a result, and you’re trying to do other work. ![]() With it’s combined high quality processor and hardware interfacing via the GPIO, it enables you to record video as well as control recording remotely, via hardware interfacing. The Raspberry Pi (RPi) is perfectly suited for this application. ![]() But what if you only needed just one camera? We will show you how. If you have a large installation, you probably had a large dedicated recording device to take care of the recording functions. They’re easy to install, and can be wired hundreds of metres away, even over WiFi. IP surveillance cameras are powerful tools for security and monitoring. Using a Raspberry Pi as an event-triggered video recorder for IP camera streams, and the Raspberry Pi camera.
