Thank you very much for your prompt reply. Upon reading your response I again tried to use the
DCS-6620 in question. After powering the unit up I depressed the "Return To Factory Default" button on the base of the camera. Using the Installation Wizard 1.11, the camera was discovered. It's IP Address is 192.168.0.104 as assigned by DHCP. Upon checking the appropriate box for the camera in question and selecting "Setup" I received a "Connection Timed Out" dialog box. Then using the "Link To Selected Device" option I viewed the camera and verified it's IP address and port number using the camera's "Configuration" button, in the now opened browser. It is set to; 192.168.0.104:80, as expected. And now while in IP Surveillance 220.127.116.11, I've tried to add the camera using the "Camera Configuration" option found at the "Tools" icon. Upon entering the correct IP Address and Port for the camera, I receive a "Connection To 192.168.0.104 Has Timed Out Or, The Model Of Camera Is Invalid" dialog box. Here's an interesting part. Upon closing the aforementioned dialog box the camera and it's "Network Settings" page is visable. So I hit the "Save" button as if to save the newly added camera to the list of all cameras in use by IP Surveillance. Only to discover that the "Connecting... 192.168.0.104" will not connect. And there is no additional dialog box. Simply a failure to connect and monitor the camera. When I go back to "Camera Configuration" It's still there and I can view video, change settings, and otherwise manage the device. Another thing I find odd. The camera seems to be monitored by the IP Surveillance program still. Even thought it has been deleted from the list of cameras. I say this because there is network traffic associated with this cam until I pull the Server with the IP Surveillance Program from the switch. Is it possible that the firmware update to firmware 1.06 for the DCS-5300 was mistakenly made available to the DCS-6600 owners on the D-Link website? Thanks again for your help.
