POE Switches

Hey Guys,

 

I've been looking around at the Reolink and Amcrest cameras and that got me thinking about POE switches.  Amazon has an array of them.

 

8 Port Gig Switch with 4 POE - http://www.amazon.com/TP-LINK-TL-SG1008P-8-Port-Giagbit-802-3af/dp/B00BP0SSAS/ref=pd_sim_421_3?ie=UTF8&dpID=416dopgvswL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=0AX3ZMKW9VAV5YJ1SHZG

 

8 Port 10/100 with 4 POE - http://www.amazon.com/TP-LINK-TL-SF1008P-100Mbps-8-Port-802-3af/dp/B003CFATT2/ref=pd_sim_421_4?ie=UTF8&dpID=31JAJBJY1yL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=0AX3ZMKW9VAV5YJ1SHZG

 

I'm thinking it would be better to have the Gig switch if you had 4 POE cameras streaming.  Right?  Then use one of the Gig ports to uplink to your main gigabit Ethernet switch.

I'm not an expert in this area but in my research there are at least 3 types of poe, 'proprietary' where you are stuck with the vendor's equipment, the original POE, and POE+. I suggest careful reading of specs at both ends before purchasing.

NRF is spot on.

Determine what the cameras support before you buy anything.

As for speed 100Mb is a lot of video from a surveillance camera. Gigabit up-link makes sense.

As long as you are buying 802.3 at/af (PoE/PoE+) compatible cameras/devices (which I recommend) you are good to go.  I have the two listed below and run cameras, and AP's from them.  Going PoE+ gives you the backwards compatibility which I why I selected these.

is there a check to be made about power per port / total power specs?

The easiest way is to look up the specs on your device. Poe+ is 48-54V at 30 watt max. PoE is around 15 watts. If your device works on 48v and draws .3 amps or less it is PoE. If more than that it is PoE+. Best to look at spec sheet to be sure.

so what I was talking about is the switch can provide up to a certain amount of current on a given port, and a total for all ports, but if you start adding up what each camera needs you may not be able to use all 4 ports for example.

Thanks everyone.  I pulled the trigger on a couple of cameras that PCDoc and I discussed on this podcast: http://homeservershow.com/lighting-cameras-and-media-center-fails-on-home-server-show-295.html

Actually, these cameras.

 

ReoLink 410 - http://www.amazon.com/gp/product/B010LH48F4?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00

Amcreset - http://www.amazon.com/gp/product/B014E995K8?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00

 

I also went off recommendation here and went with this POE switch:  http://www.amazon.com/gp/product/B00LP3E05C?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00

 

I hope to be able to compare them for you.  In between all the other stuff going on!
