Building CCTV-net - experiences / ideas
-
As Msje Chesnokov keeps demonstrating awesome possibilities in the world of cv and image processing, I have recently hit on a problem that requires building a network of wireless/wired cameras, building storage and monitoring solution, variation of low light, indoor, as well as outdoor harsh environment conditions, motion detection etc. Looking around, seemingly good stuff seems pretty expensive, almost looking like some niche monopoly :) Ideally it is all wireless, fault tolerant (not only on dc power etc), and has a 'networking' capability for expansion and more. However, it can all vary, it is a network and each site has its own preferences on indoor/outdoor placement, light conditions, redundancy required and being able to scale seems important here; so I understand it is a tall and epensive order to start with but network provides that scope I guess. My q being, has anyone hit on a no rip off setup for a good number of cameras, what type are they, any review/experience would be helpful. Also any ideas on setting up storage and processing hardware and a well secured network for image distribution (fault tolerant to say power cutoff) etc? Ideally it is all easy to program and extent rather than a closed and attacker friendly or neighbour-linked WiFi setup.. 2.4Ghz can be quite dirty and is in this instance, any experiences there would be appreciated too. The entire shabang is meant to hit a few ADSL/DSL lines and push it out onto the net.. Heck, any idea on how to begin with a test environment and scaling it, from radio to routing to ip to distribution, to fault-tolerance would help.. key being growth potential, security and programmatic scope. Am I nuts thinking getting friends to look into building custom sensors would be cheaper and provide more scope for play at the same time? Cheers..

Sounds like fun to experiment with and learn about then write an article on here or somewhere else.
When everyone is a hero no one is a hero.
Looking at this great source for a start, http://www.codeproject.com/KB/audio-video/cameraviewer.aspx I hit on the products: http://www.axis.com/products/video/camera/index.htm And googling for each kind of makes even the professional photography cameras look cheap in comparison. Just cannot believe it is so expensive PER piece, so anyone with experience of Taiwan manufacturers in IP camera space could help out a lot :) Take a look at a price of a very, very good desktop camera (okay, you'd need repeaters for USB power say), put into a casing and 'environment' infrastrucure (Linux or Windows backed hardware) twice that price, it still beats it by 300% or more margin (more likely get to build a supercomputer with 1500$ a piece say).. must be me, hence the query.
