Mini Safe

The Protekto Mini Safe is small enough to hide in cars, under table, chairs and desks. It can hold Jewelry, cash, credit cards and other valuables and keep them hidden and protected.

They way the Protekto Safe works is it's both Glued and screwed down in place and can only be opened with a lock and key. Once the draw is in place, you can not unscrew it.

It's extreamly rugged and even in a machine shop would take hours to open. So don't loose your key. The keys can not be duplicated!

Security Camera-to-DVR Setup on Linux?
Slashdot article
mrperkins asks: "I have been asked to help a friend setup a Linux DVR (Digital Video Recording) system for security cameras. Previously this has been done on Windows XP using Avermedia video capture cards from the MP3000 and MP5000 series, and using their bundled software. They have a Linux version but the software is horribly broken. The Windows software allows playback/recording/backup from 4-16 cameras. This works reasonably well but certainly has it's share of problems - the PC's hardware being only one. Can this be done on Linux using Free Software and compatible hardware? I have heard that the frame rates achievable under video4linux are simply too slow, but I would like to prove otherwise! Are there any software packages that can do this kind of thing (not just a single stream but a fully featured package)? Also, what cards (pref. up to max $200US) would you recommend? If anyone is already doing this kind of thing please let me know what you're using!"

Cambozola and other Open Source DVR Tools.
Cambozola Cambozola is a very simple (cheesey!) viewer for multipart jpeg streams that are often pumped out by a streaming webcam server, sending over multiple images per second. Netscape will display and refresh these automatically, but Internet Explorer and other browsers do not - they will only display the first image.

Axis Camera Gallery Examples of what Cambozola is good at displaying

Webcam software

If you want to stream from your own server, you'll need to use some streaming webcam software, some Linux-friendly package are:


Livecam Server

Motion is a software motion detector. It grabs images from video4linux devices and/or from webcams (such as the axis network cameras). Motion is the perfect tool for keeping an eye on your property keeping only those images that are interesting. Motion is strictly command line driven and can run as a daemon with a rather small footprint.

ZoneMinder a Linux video camera security and surveillance solution. ZoneMinder is intended for use in single or multi-camera video security
It is designed to run on distributions which support the Video For Linux (V4L) interface and has been tested with video cameras attached to BTTV cards, various USB cameras and IP network cameras.

Even E-bay 2 two on auction right now for under $20. 1/20/2003
The main reason I like the 4400r board is they have a very distinctive shape and color that allow me to look at a thumbnail image and be 100% know for certain that the board has a Conexant Fusion capture chips on it.

About the KMC-4400R

The boards are 120 Frame per second boards. Meaning there are 4 image capture chips on board. Each able to capture a 30fps full motion video stream. It support up to 16 cameras.

They work with DigiNet software I have tried Version 4.13 and 4.16 for Windows 98/Se/2k/XP. DigiNet is often resold under many differnet names. Elite, Avalon, Apollo etc... I have some of the manuals here

This board is supported by the bttv driver in Linux 2.6.10 and later as well as in FreeBSD it shows up a 4 seperate BKTR devices. Under freeBSD I had to write a little utility to configure a multiplexer chip on that board.

It uses the Bt878 / Conexant Fusion 878A chips, one of the most popular and my favorate.

On these boards is a PCI bridge and an Intersil CD22M3494 Chip. The Intersil chip is what makes these boards really interesting. This is a 16x8x1 BiMOS-E Crosspoint Switch. in english what that means is that it's like a patch pannel. I can switch any input to any port on any chip.

I have personaly written a utility to enable this board by programming the Crosspoint switch. It's for FreeBSD 4.9 and 5.1. Once this is ran, each Bt878 look like a stand alone capture board.

My livecam ( Now supports these boards on FreeBSD to provide 4 live streaming video feeds. I have the source code available also.

Since 1995 Proprietary Access Control Enterprises, Inc. (PACE) has been a systems integration company specializing in corporate security.

Due to an acquisition and new business focus, PACE is selling off the Digital Video Resources division. Included with this sale are all website and marketing materials that have been created around the hardware compressed DVR systems.

eLViS: Linux Video Surveillance
eLViS: Linux Video Surveillance
From an email exchanges with Roy Souther of

Linux Video Surveillance AKA eLViS is an Open Source project to provide a GUI for the motion capture program, another Open Source project. You are welcome to download the code.

eLViS is unlike e.L.V.I.S (from Pervasys) in that it does not do live Internet streaming as is the main feature of e.L.V.I.S.
e.L.V.I.S (electronic Live Video Internet Streaming - from Pervasys), now defunct was a reincarnation of the Livecam video server and shared much of the same source code as livecam.

eLViS is still in it's infancy but has had a lot of interest. Currently we are looking for two more investors to help advance it to the next level of being a quality product and still remain Open Source.
