I am in the same situation. I have the Syn 214 Play and a home network (gigabit). I think for us POE is the way to go for the ip cameras. I have a data comms cabinet that has a 24 port patch panel and a TP Link router. I think I will get a 16 port managable switch and a separate POE switch say 8 ports. IT is hard for me to find a 24 port switch with 8 POE ports, so 2 different switches might be the go for me. Additionally, I will probably go for a 10/100 POE switch as this should be more than adequate for what I need.
There are POE injectors that you can buy if it is only a couple of POE capable ports you need.
