An Introduction to Video Surveillance with 'Motion'

Filed under
HowTos

Videochatting and amateur pornography are all well and good, but have you ever wondered what else you can do with that webcam?

Well, thanks to the efforts of many dedicated open-source coders, any half-decent PC can be turned into a motion-detecting, snapshot-making, video-recording D.I.Y. security solution.

motion, a program designed to detect movement by analyzing streams of images, is one great way of doing this.

And while installing and configuring this piece of software used to be a royal pain in the butt, with the advent of Sarge, we now have an easy-to-install motion package right in the main repositories.

Before we go on, you should know that while motion was originally designed to interact with devices managed via Video4Linux (V4L), it is also able to interact with network cameras accessible via HTTP over TCP/IP.

In this introduction I will cover using a V4L video device (webcam, TV card, etc.) directly attached to your PC, but once you get the hang of it, using network cameras instead won't require much effort.

Linux Kernel Security in a Nutshell: How to Secure Your Linux System

The Linux kernel is the core component of the Linux operating system, maintaining complete control over everything in the system. It is the interface between applications and data processing at the hardware level, connecting the system hardware to the application software. The kernel manages input/output requests from software, memory, processes, peripherals and security, among other hefty responsibilities. Needless to say, the Linux kernel is pretty important. However, with power comes great responsibility, and the Linux kernel is no exception to this rule. Kernel security is critical: it determines the security of the Linux operating system as a whole, as well as the security of every individual system that runs on Linux. Vulnerabilities in the kernel can have serious implications for Linux users, and it is extremely important that users stay up-to-date on news and advisories pertaining to kernel security. Read more
