joined 2015, first post.. nice
any vlan configuration on any device is the same..
you have to connect the dahua poe switch to your router or switch... on both ends the ports have to be "tagall". this is your uplink
then you configure the ports for the cameras on the dahua poe switch as untagged.
there is a big but:
any traffic between vlans will go through the router... only if you are using a layer 3 switch routing on switchsite is possible. if you are using the same vlans on both switches the switches should be able to route traffic between them without the router.
for cameras which have low bandwith it should not matter,... when you need high bandwidth you can easily max the power of the router (when using low end hardware) and/or the uplink between the switches which might affect your whole network
