Best choice PoE gigabit network switch?

[micko_escalade]

Hello,

I need 16 port gigabit switch with PoE (for IP cameras in home network). In my research I came across this
NETGEAR ProSAFE JGS516PE https://www.amazon.com/gp/product/B00GG1ACX2/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=ATVPDKIKX0DER Price after rebate: $144.99
Never had Netgear before. Should I go with Cisco?

Any suggestions are much appreciated!

Make sure the IP cameras support gigabit PoE. An ethernet cable has 4 wire pairs. 100 Mbps ethernet needs only 2 pairs, so 100 Mbps PoE uses one of the two unused pairs to carry power.

Gigabit ethernet needs all 4 wire pairs. So Gigabit PoE works by running DC power over one of the wire pairs, and the normal ethernet signal is added on top. If you plug it into a device which doesn't support Gigabit PoE, you can fry the device. It's supposed to have safeguards to make sure the other end supports Gigabit PoE before running DC power, but that's a last line of defense. I really hate relying on a last line of defense to prevent equipment destruction.

Also be aware that the switch you've linked only has 8 PoE ports. The other 8 ports are regular ethernet ports. If you have more than 8 cameras, you're going to have to find a switch that has more PoE ports.

And while the max power per port is 15W, the total power cap is 85 Watts. This shouldn't be a problem for IP cameras (usually 5-8 Watts max), but just to be safe you should check that all the cameras at night with IR on won't exceed 85 Watts combined.

Wow, thank you for that! I was not aware of that!
What needs to say on my IP camera that gigabit PoE is supported?

Sorry but that is utter mumbo jumbo. The standard for any POE device either PSE or PD is no different for 100BaseT or 1000BaseT. A gigabit PSE device will do no harm to a 100BaseT PD as long as the devices are IEEE802.3af or IEEE802.3at. If you are using proprietary equipment such as some Ubiquity stuff you can not use it on other PDs, it shoves 48v down the line regardless with no sensing. Sorry you are just wrong.

Thanks for your input!
