Hi together,
Dump Switch
pfSense comes with enough LAN port and you might be
able to insert a dump switch on each, and you don´t need
VLANs, pure routing is here the entire job of the pfSense
Layer2 Switch
pfSense is sorted with one or more VLAN capable switch
and is doing the entire routing between the VLANs on top
of its other work!
Layer3 Switch
pfSense is sorted with one or more Layer3 Switches and
the switch(es) are routing the entire workload self, this free´s up your pfSense for doing other work, or you may be able to install some more packets without problems.
So this might be the first problem, for VLAN or not VLAN
usage. And the other thing is how many Volt/Watt are all the cameras are needing, so you should be looking for
two different numbers their;
Volt/Watt per port that all cameras will be getting enough per port
the entire electric budget must be also covering all port
with "xyz" Watt in total!
So if your power budget total and per port is right and
you have a really let us say powerful pfSense you can
also go with dump or layer2 switches.
