POE switch / injectors

Post by Silly Car »

I need to power up at least 5 possibly 6 cameras via injectors or a switch with the following constraints:

4 cameras are wired back to a single place so I’m thinking a minimum of a 4 + 1 POE switch here
1 camera (possibly 2) are wired back to another location so I’m thinking a normal gigabit / 10/100 switch with 1 / 2 POE injector but I’m assuming each injector will need a separate 240v feed. Cost wise, might I be better with just another POE switch?

Cheers

Tp-link 5 port PoE switches are cheap as chips and work well enough.

Injectors are ok if you have a three pin socket somewhere near by, but Switches give you more options.

Cheers, I’m guessing one unmanaged switch is pretty much the same as any other?

TP link seem to be around £25 each for a 5 port switch

Yep, they're all shit. Joking aside, the only things to check is back plane speed and port speed, I doubt if any unmanaged switch has a published backplane speed

I'm sure that as long as the switch has POE ports he will be fine, it's just a house setup! The cheaper POE switches are designed for just this scenario are they not?

I would try and wire back everything to 1 central POE switch if you can. POE Injectors are a pain to hide cables in houses and take up your power sockets!

Just check that the max wattage of the switch will drive the cameras ok.
