UD1,
Are you planning to use a network cable tester to verify the cable before you do any other work?
IPVM provides a cable testing guide.
Maybe you have already accounted for the cable testing time, or specified a per-hour rate for that.
The reason I ask is that I have been called in to troubleshoot projects where CAT5e cable was used with video baluns for analog cameras, and the cable was reused when IP cameras were installed (and encoders put in place for some of the newer analog cameras).
The problem was that some of the cameras were not getting all of their video through.
The Technical Details
The trouble turned out to be that some of the CAT5e cable runs were poorly installed and could not support more than 10 Mbps. On a 1 gigabit network, the network connection was automatically being negotiated down to 100 Mbps or even 10 Mbps.
About a year ago I came across this chart:
10 mbps = 1.25 megabytes per second
100 mbps = 12.5 megabytes per second
1000 mbps (1 Gbps) = 125 megabytes per second
With IP cameras you will be sending more (or maybe very much more) video data across the cables, depending upon how many megapixels the camera image is. Although I have seen installations where some of the cable runs would only support 100 Mbps connections, since CAT5e cable is designed for 1 Gbps, doing that means you are re-using a cable that has been incorrectly installed, and could further deteriorate over time.
The Customer
It can be important to explain to the customer why existing cable may not be up to snuff. They don't know about any of the networking details, or that megapixel cameras mean a lot more video data. Otherwise they can find it suspicious that cable which was working for the cameras they have now, won't necessarily work for the new cameras.
