Questions about surge protecting Ethernet

[TubsAlwaysWins]

So does anyone know how beneficial using one of the Unifi Ethernet Surge Protectors https://www.ui.com/accessories/ethernet-surge-protector/ is, compared to what their POE bricks and switches can offer? (On properly made ESD shielded cable) Im assuming that its better to lose a $15 surge protector compared to a $200 switch but im just curious if anyone knows much about this

I think that you would still have a PoE injector or switch in the chain. This would be for outside-mounted devices like cameras or outdoor APs that could be struck by lightning, causing a huge surge of power. The surge protector would either take it or possibly die, but should prevent the excess power from coming into the house and killing the injector/switch. 

 

I suppose it would also help the other way - if your house/utility power surges this device would theoretically save the AP/camera from death. But only after the surge had killed everything else before it.

I know I still have to have the POE injector or switch in, im just wondering how good their grounding capabilities are. Im just gonna put in the protectors as well though since I have enough on site for this project
