I asked about this last year, it's come up for us here
again, and I'm wondering if any one has any other
suggestions or knowledge I can tap.
We are looking at options for digital video recording
on a large scale - approximately 300 outdoor freeway
cameras.
All inputs are analog, majority are direct fiber
connects with a handful of wireless.
Requested archive time of around 2-5 days (5 days
better).
Frame rate should be at least 15 FPS, 20-25 is better.
Higher the quality the better, I know this gets tricky
with space & compression, but I'd like minimal
pixelization & artifacts. These are big shots being
recorded, there's pretty much always some kind of
movement visible, even if it's just trees blowing or
camera sway, so compression could be tricky. Alot of
what's recorded could be 1/2 mile away - so
pixelization degrades the usefulness substantially.
I've used both Pelco & Vicon DVR's - both do the job
somewhat, but the record quality isn't as good as I'd
like for the money.
It would also be nice if the solution would also
automatically spit out a jpg every X seconds and a
seperate compressed video for medium bandwidth
streaming to fill some future projects.
Solution must be networkable, I don't want to run
around to different boxes to pull video - I want to
sit at one terminal and bring up the archives I need.
Modular expansion would be helpful with our budget
too.
So, my question is:
#1 Do I go with 30 Pelco or Vicon boxes? Bring the
number of feeds down per unit to pump up the quality?
Seems like I'm paying a premium there on hard-drive
space - plus limited upgrade options. And it doesn't
take care of my JPG & streaming needs.
#2 Do I go the route of buying everything seperate:
A) 300 digital encoders (which we pretty much have
already)
B) A multi terrabyte SAN unit
C) A software package to tie it all together
D) Upgraded network switch to handle all the
traffic.
This seems like a nice intuitive way to do it, takes
advantage of our existing equipment, plus it buys me
the most storage for my $$. But I don't know how
feasible it is.
Does anyone have any experience they can share (for
free please, I'm not asking to hire a consultant) or
aware of other users doing similar things?
Thanks!
