Have you certified the network line? If not can you get your hands on a certifier? Using the Ping command is not a acceptable way of testing a network cable and without a proper certification report you can't rule out the cabling and terminations.
Aditya, can you connect your Standard Laptop to your Sony Camera with a crossover and ping it? Just to isolate. You will either need to setup the camera wih a static ip or make the laptop a dhcp server. If the camera is POE only though it gets tricky...
Check your ARP / PING settings on the camera/s.
Besides checking PING / ARP settings, the best testing would be to plug in the camera one-one-one to your PC / Laptop using cross-over and check for any abnormalities. This way you limit your problem to only 3 entities - the camera, the cable and the pinging device (PC / Laptop). You've got to take a 'process-of-elimination' intitiative to derive conclusion.
Basic items to validate. Distance from connector to connector. Is it POE? Does the Sony camera have LEDS at the connector? A green link(?) Led and an amber/white flashing data LED (when data is present). The cable run is free of electrical interference. Were the connectors afixed at the sight? There are two types of connectors that are easily mixed up. One for solid strand copper and one for twisted strand copper. Is the cable shielded? More after breakfast. :-)

If the customer is responsible for the network, all I would think you would need to do is just verify the camera is working. If you can direct connect or locally connect to the camera and do a continuous ping test (ping -t xxx.xxx.xxx.xxx) for at least 10 minustes or so without dropped packets (or I would say 1 or 2 packets in a 10 minute timeframe would be acceptable), and get live video from the camera by using the web interface on your laptop, and if you certify whatever jumpers or short cables you may have used connecting the camera to the customer's network, then you've discounted the camera being the problem.
But if you can't explain with confidence to the customer why your equipment is not the problem, then you may need to subcontract an experianced network technician who can confidently say the problem is not your equipment, but their network.
You may have properly used techniques and procedures to verify your equipment is working, but sometimes it's not just about doing the procedure, it's about having the confidence in your words that you know what is or isn't. And your'e really going to need an experianced and knowledgeable network person working on your staff if you are going to be attaching more security stuff on customers' networks, because IT staff will always blame and make you troubleshoot your stuff first so they don't have to do the work if they don't have to. That is just the way most of them are.
Please clarify this statement: "when we Connect a Standard Laptop to the same Port"
Are you connecting the laptop with it's own cable 'to the same port'?
Or - are you using the same cable that the camera (and the replacement cameras you also tested 'on this port') was using to connect to that port?
So guys - thanks for all the help. Great insights., Preliminary observation - 1. Cable from Network Switch to Cam could be a point of failure, will check this out 2. However, I understand from our team that when they connect a cross cable to the camera using the same cable as above, there is no packet loss. I am starting the eliminating problem issue from tomorrow and will keep you guys updated. Thanks a lot.
