Network video cameras

Have not priced out any but I can ad some points to the network side.
Streaming video in general is a bandwidth hog, meaning in most cases it will
eat what ever it is given. There are a couple of ways to combat this, one is
to put them on their network that plugs into a 2nd NIC card on what ever
server that is going to handle the video (assuming that you are archiving
the video). The other option is to set up VLan's and segment them out on
their own subnet. You will need switches that support VLan's, like Cisco,
and higher end D-Links. I would also recommend a router that has QoS support
in it. QoS (Quality of Service) routers will allow you to prioritize certain
network traffic, like Vantage, so it will get processed by routers 1st when
collisions happen on the network, which in turn makes the traffic with the
higher QoS move a little quicker. Hope this helps

Anyone done any research on Network/IP based video cameras?

Looking for information on quality/price/peformance etc.

And, of course - how much network bandwidth gets chewed up in the process?

With Vantage on a network I've been hesitant to introduce video cameras but
...

Thanks -

Todd,
I actually install/service surveillance systems as a contractor.
I would consider first how many you want to view and whether you want to
capture.
The geovision product is pretty capable and very affordable relative to
honeywell products and PELCO.
They record, playback, and archive very well. To minimize network useage,
you can chose number of cameras in playback view and also throttle
throughput.
However, internet IP cameras, like AIRLINK, which also have PTZ control, can
be set to run wirelessly with decent control and monitoring capability. I
would not rely on them alone for true security situations, but for basic
monitoring, they are pretty good. Better still is that if you bring in a
second router/AP, you can isolate the bandwith and separate it from the rest
of the network. No special pc hardware required....just a little TCP/UDP
port configuration. Both support expandability up to 16 cams per system....

Let me know if you want to talk more off list...

Todd,

My research in this area shows that there seems to be a split in the
area of video surveillance. You've got the traditional crowd that are
of the old "analog over coax" mentality and you've got the new IP-
based, digital guys. The old school guys are trying to bridge over to
the data network but their core technology is still rooted in the
analog world. There's a lot happening in the area of IP-based systems
and they're improving daily. I've been working with a young, up-and-
coming company called i2c Technologies that has a very slick system.
The capabilities of the system are very impressive. The system was
designed by data guys that have bridged over into digital video versus
the other way around. Check them out at i2ctech.com, ask for Jeff or
Vince when you call and tell them Steve at Wrayco sent you.
