is this the best design for a home cctv system?

I need approx 2-4 cameras.

 

I will power and connect them using PoE, rather than via wifi and mains electricity so that they are immune to wifi jammers.

 

The PoE cables will connect to a switch, then to a PC, then to a router and modem, all powered by a UPS, so that even with a power outage the system will still work.

 

Would you recommend doing it differently?

Sounds simple and straight forward enough.

Hard wired network is always a better option than wifi as long as cabling is possible.

Make sure to size your ups correctly and remember its a ups, not a generator so don't expect long back ups with it.

If you're only going no more than 4 cameras, you may even consider one of the nvrs with built in Poe switch.

Both PoE and non PoE powered cameras transmit signal same way over Ethernet cable, so up to you if you want to pay extra for PoE.

Yes, but POE makes it cleaner and easier
