ZoneMinder is a suite of applications intended for use in video camera security applications, including theft prevention and child or family member monitoring. It supports capture, analysis, recording, and monitoring of video data coming from one or more video or network cameras attached to a Linux system. It also features a user-friendly Web interface which allows viewing, archival, review, and deletion of images and movies captured by the cameras. The image analysis system is highly configurable, permitting retention of specific events, while eliminating false positives. ZoneMinder supports both directly connected and network cameras and is built around the definition of a set of individual 'zones' of varying sensitivity and functionality for each camera. This allows the elimination of regions which should be ignored or the definition of areas which will alarm if various thresholds are exceeded in conjunction with other zones. All management, control, and other functions are supported through the Web interface.
SILC (Secure Internet Live Conferencing) is a protocol which provides secure conferencing services in the Internet. It can be used to send any kind of messages, in addition to normal text messages. This includes multimedia messages like images, video, and audio stream. All messages in the SILC network are encrypted and authenticated, and messages can also be digitally signed. SILC protocol supports AES, SHA-1, PKCS#1, PKCS#3, X.509, OpenPGP, and is being developed in the IETF. The software is delivered as SILC Client for end users, SILC Server for system administrators, and SILC Toolkit for application developers.
motion uses a video4linux device for detecting movement. It makes snapshots of the movement which can be converted to MPEG movies in realtime (or later for low CPU usage), making it usable as an observation or security system. It can take actions like sending out email and SMS messages when detecting motion.
PLIB is a set of libraries to write games and other realtime interactive applications that are 100% portable across a wide range of hardware and operating systems. It's used by Majik3D, FlightGear, and others, and includes libraries for GUI widgets, sound replay, geometry, scene graph, joystick, and fonts/text.
Motiontrack is a set of tools that detects motion between two images. It is able to successfully distinguish random flicker from real object movement by applying a set of filters to the images, and can optionally ignore given colors and/or image regions. The roadmap provides for being able to identify objects by pattern detection and AI routines. Currently, this part is able to turn line-art images into ASCII-art text and auto-align images which are slightly staggered or contorted. This might also be useful to correct the perspective of image sources from different 3D angles.
DIIT provides a simple tool that can hide a message inside a 24-bit colour image so that knowing how it was embedded, or performing statistical analysis, does not make it any easier to find the concealed information. It also provides a framework for implementing other steganography algorithms for use in the tool.
Linux Video Surveillance (eLViS) provides a user interface for watching motion frames captured by the motion program as JPEG files. It has VCR-like controls, rewind, stop, play, and fast forward. It lets you view up to four motion threads (camera sources) and has a simple configuration panel.
