    Dahua IPC-HFW1320S will not send NTP packets

    And now back to DHCP problems which kick this all off.... I still have DHCP issues in that the camera does NOT issue a DHCP request upon startup. I was able to under certain conditions for the camera to make the request. I am unsure what those conditions are. Here is why. If I select the...

    Dahua IPC-HFW1320S will not send NTP packets

    After reporting last nite I went back and experimented with a couple of things.... I added 2 response items, netmask and default gateway, to the dhcp server config. And as you have speculated the camera was happy and stopped making repeated requests. I looked at the dhcp RFCs to find out what...
