What is a PoE Switch and When Do You Need One?
A PoE (Power over Ethernet) switch is a device that provides both data and power to network devices, like security cameras, using a single Ethernet cable. This means you can install cameras without needing separate power sources, making setup easier and reducing cable clutter.
If you're setting up security cameras and need them to be powered through the same cable that connects them to the network, a POE switch is a must. It simplifies the process, especially when cameras are placed in areas where running power lines would be difficult or expensive.
Which PoE Switch Should I Use?
As for the specs one would need to know before purchasing a PoE switch, here are some key factors:
PoE Power Budget: Coram recommends using PoE+ switches (up to 30W per port). PoE may not provide enough power budget, and PoE++ is typically overkill for most.
Number of Ports: You need one port per camera and, ideally, 2 spare ports to connect the switch to the router and Coram Point.
Unmanaged vs. Managed: Unmanaged switches are simple plug-and-play, while managed switches offer advanced features like network monitoring and control, which may be useful for larger or more complex systems. If you are new to network switches unmanaged switches will be sufficient, but if you have a large deployment (30+ cameras on a single site) you might have to go with managed switches (such as Cisco Meraki).
Recommendations for unmanaged PoE+ Switches
Below are some recommended unmanaged Netgear POE+ switches.

24 port POE+ https://www.netgear.com/business/wired/switches/unmanaged/gs324pp/
48 port POE+ https://www.netgear.com/business/wired/switches/unmanaged/gs348pp/
Recommendations for managed PoE+ Switches
Managed POE switches can be more complex to purchase and set up and involve various tradeoffs. If you have questions, feel free to reach out to our support. We recommend going down this path only if you are an experienced IT professional or working with an MSP.
