The dlink cameras 932, 5010 do not connect back to the network after a power outage. It does not matter whether they are wired or wireless. To reconnect you need to power them off and on and then they connect back to network. Looks like the cameras only try once after a power outage to reconnect. It should be a simple solution within the firmware for cameras to try again in 5minutes or so to reconnect after power is back on!
Come on DLINK this is doable and easy fix!
I love the cameras as they are easy to install and provide a good image. But this simple issue could make me change my 5 cameras to something that is more reliable...
