There are DVR/s on this private network and a new one was added and it worked for a week then stopped. Tested unit ok. Would it of worked in the first place if the IP address was then duplicated in the beginning?

    If the Ip address was duplicated then at the time of setting why did not it show IP conflict message? Is it the same network? How did you set the IP addresses? What OS is there? Is the environment with mixed OS? Who added the new one meant, you people only or service engineer? Please come with more details.

    Thanks - so do you agree that if at the time of adding device the system would not of worked for a week if the ip was a duplicate.this is one network with 3 different camera software packages (icons) (hickvision) and dahau the operating system wi7 it always worked then the engineer from the DVR supplier added in the unit and the system was fine for a week. all that failed was the dahau system(our one) customer thinks that we are the cause of the problem like telling us we have duplicated an IP address but how would it of worked in the first place. the network is the problem i say

    all i want to know/confirm with everybody that the system would have never of worked if there was an IP conflict then I'm in the clear (am i correct that we would have had a message immediately). We use static IP for our DVR. Hoping I get some solid answer to my main concern.

    Probably for duplicate IP, the dvr(s) is/are not reachable. For this purpose, first switch off all the systems then start one by one. Now ping one by one. If ping works, again switch off and check if there is still pinging or not. If yes, search the system/machine for duplicate IP. How your supplier/service engineer added units, like Reception 1, First floor main gate etc. etc, something like that, or takes another way?
