poe switch needed

RobTi · 2 Jun 2022 at 14:32

Hi i need to add a 5 or 8 port switch to my cupboard and decided to go poe to power a couple of cameras in the future , so just wondered if there was any to avoid or any that are the go to ones ?
Thanks

I've got a TP-Link TL-SG105PE which has been faultless so far and reasonable cost. Powering PoE camera, Wifi AP, plus my Helium miner and a Raspberry pi with PoE converters.

If you don’t need a smart switch then buy the one that has full 1 Gbps per port, is cheapest and looks how you want. They’re all much of the same to be honest.

if you not bothered, you can pick up a Cisco 2960S 24 port POE switch on EBay for around 50 quid.

Not quite. There are multiple different flavours of PoE. That supply anything from 12V to 54V. If the OP buys a 24V passive PoE switch from Mikrotik and plugs his Cameras into that it could be fun and games. Or more likely nothing.

So they almost certainly want a 48V 802.3af (PoE) or 802.3at (PoE+) but unless they are powering Pan/Tilt/Zoom cameras they are unlikely to need 802.3bt (PoE++). For cameras with powerful IR or soft white LEDs the OP will need PoE+. If it’s just a doorbell type then PoE will probably do it. PoE switches also burn a lot of power. If it’s only 2 cameras then a couple of PoE injectors might be a better option. Or just buy a cheap 4-port PoE NVR.

That’s a great switch. If someone else is paying for the electricity- 120W minimum continuous power draw. That’s 20 LED lightbulbs. For 2 cameras. It’s a great piece of equipment and for the office I would. For home maybe something smaller.

Two cameras happens to be the number that Synology support on a NAS iirc, personally for two runs, I would have thought injectors would be adequate, but then again I would use an NVR, because CCTV is one of those things where bare metal NVR makes a lot of sense as a security device and is easy to power everything from and keep powered via UPS. You can of course power a NAS via UPS and a PoE switch, but a 4 port NVR isn't actually that expensive.

That's the exact model I have, works flawlessly on latest firmware.

I use POE as well and there hasn't been any issues up to now. Had it 2 years on V2.

I am lucky as my company have reaplaced all Cisco kit that goes out of support this year so I am now fully Cisco at home

Thats a bit like saying you’re lucky because your company gave you an old Rolls Royce in the middle of a fuel crisis. Yes, it’s lovely. And then there is the ruinous running costs. I suspect the really lucky folks are your electricity suppliers.

I used to run a bank of servers and PoE switches galore. When I shut down to passively cooled appliances and the bare minimum of switched capacity my electricity bill dropped by almost 70%. It was incredible. They just suck power 24/7/365. And mainly they’re doing very little.

But I can’t argue that it’s not nice kit.

Agreed, better off selling it all and buying more home friendly stuff.

Same, I used to have a rack full of Dell servers, HPE switches and whatnot, was great fun to play around with. Now I run all the same services on a little Dell box using 10% of the electric. Glad I got shot of them before the energy hikes too.
