If you’ve followed my build so far, you’ve got your Synology NAS ready to record. But how do you get four or five high-definition cameras to talk to that NAS without a mess of power adapters and “Silicon” clutter? You use a PoE (Power over Ethernet) Switch.
I’ve seen guys try to use individual power supplies for every camera. It’s a “bird’s nest” waiting to fail. A PoE switch allows you to send both data and power over a single Cat 6 cable.

Why 5 Ports?
For a standard residential “No-Cloud” setup, a 5-Port PoE Switch is the sweet spot. It’s small enough to tuck into a media cabinet or a closet, yet powerful enough to run four cameras (the 5th port goes back to your main router).
The “Iron” Advantages:
- One Plug to Rule Them All: You only need one wall outlet to power four cameras.
- Hardwired Reliability: Unlike Wi-Fi cameras that “ghost” when the signal gets weak, a PoE-connected camera is a “Silicon” lock. It never drops.
- Heat Management: Professional PoE switches are built with metal housings to dissipate heat. In a 24/7 security environment, “Iron” stays cool while plastic melts.
Contractor’s Tip: Check Your “Power Budget”
Not all PoE switches are created equal. You need to check the PoE Budget (measured in Watts). Most bullet or turret cameras pull about 5–10 Watts. A switch with a 60W budget is plenty of “Iron” to handle a full 4-bay Synology setup without breaking a sweat.

Contractor’s Note: The “Sub-Panel” Rule
“In 30 years, I’ve seen guys try to wire an entire kitchen remodel into one existing 15-amp circuit. It’s a fire hazard. Your security system is the same. Don’t choke your main home router by plugging five high-bandwidth cameras directly into it. Use a dedicated PoE switch as your ‘Security Sub-Panel.’ It keeps the heavy ‘Silicon’ traffic on its own line and ensures that when your VISTA-20P sends an alert, the path to your NAS is wide open and rock-solid.”
The “Final Connection” Bridge
Once your PoE switch is mounted, you are ready to start “roughing in” the Cat 6 wiring that will eventually carry your VISTA-20P alerts and camera feeds. I’ve documented the exact switch and wiring specs I use on my Master Resource Page—visit it now to see the “Iron” foundation of my build.
