Re: cameras on network

Correction: you may need to multiply by 30 if there's a chance everyone is going
to be viewing all cameras at once (which will no doubt crash your 100Mbps
network.)

If you know what bitrate you intend to use (check camera specs) you could
simulate the load using a packet generator or even an encoder like Windows
Media Encoder. Multiply by 10 and you'll have your network impact.

I have a 10\100 Lan which has over 30 pc connected to it.
My company are considering adding 10 ip cameras and monitoring the site and
factory, my question is can any one see any problems with this and possibly
point me in the direction of the best cameras to use.
My main concern is the traffic created by these cameras slowing network and
stopping users from working.
the cameras will be running all the time and video will be recorded for
future use.
If any one has any advise whatsoever it would be much appreciated.

Many thanks.

Depends what type of cameras you use, and if they are higher end
cameras, such as an axis, sony, or even an encoding box like verint,
then the bandwidth each camera uses depends on the video quality
settings. If it's an mpeg4 camera, you're probably going to use
anywhere from 512kb/sec to 4mb/s. If it's mpeg2, the bandwidth will
increase. Sorry if this is very broad, but i'm on my way out of the
door. I used to work for a company that provided video solutions like
this all the way up to the enterprise level. Let me know if you have
other questions and i'll try to help you out.
