The use of a switch has its cost. Every time you daisy chain another switch there is some time latency. Also traffic will cause some latency. I would suggest that you consider having one switch for all of your cameras and your B.I. computer. With one port of switch "S" (S=security) going to your WiFi Router switch. Then have another switch "O" carry all of your office network stuff, with one port going back to the router. Then either have a switch "M" for your T.V.s or wire them directly to two ports on the router. Try to segregate your data flow. As you can guess the security net will be a data hog. So try to keep data flow inside of the house away from the router. Reserve the switch on the router for data that needs to go out to the WWW. Now even though all devices will be on the same sub-net. The switches set up as I described above, will keep the data segregated. Now with this being said, I have to realize that POE has a greater distance restriction. If you have to use 2 or 3 POE switches. take each one back to master security switch. Dont daisy chain.
