2 port PoE extender

[mike_201907_662346852388871]

I have a front gate camera (811A) that is about 150 meters / 500 feet from my NVR.
I need to get a PoE extender but I was wondering whether I could get one with 2 ports and run a second camera (actually a Reolink PoE video doorbell) and get both feeds into my NVR ?
if it is possible, are there any particular specifications I need to check ?
thank you

@mike_201907_662346852388871 what you want to buy is a simple 5 port POE switch with 802.3at/af support. That's pretty much any POE switch on the market today.

There are many many POE switches on amazon, including say a 5 port fast ethernet switch like this one, that supports 10/100 Mbps (you don't need a gigabit POE switch for reolink products, but you can certainly buy one for $10 more if you want to future-proof).



Plug the non-POE ethernet data-only cable into PORT 5, then plug the other two ethernet lines running to the 811A and reolink doorbell into any of the other remaining ports on this same POE switch (you'll be able to plug in 2 more POE or non-POE devices into the remaining 2 open ports in the future).

When you plug the data-only ethernet into your main switch, which should also have the Reolink NVR plugged into it -- then the NVR will pick up the doorbell and 811A and assign them to whatever empty channels you have left on the NVR.

What's implied above, is that reolink cameras do not have to be directly connected to the reolink NVR. As long as the data from the camera can reach the NVR, the NVR will recognize the camera.

Conversely, as long as the camera eventually gets POE to it so it can operate (from either a short distance or from far away), AND the camera is on the same network, the NVR will pickup the camera. The reolink NVR just makes it easier by having a built-in POE switch in it already.

Your issue though is distance of 150m. Max transmission is 100m/328ft for Cat5e/6. So you will need to put some sort of switch (regular or POE) to act as an extender within 100m of the gate. You don't need anything special other than another switch to boost that data signal. (Pro-tip: Use solid core 100% copper cabling for long distances, not CCA (copper-clad aluminum) and definitely not any stranded cable; also Cat6 is better, because the min specs provide for thicker gauge wire than Cat5e)

Depending on distance, you might be able to run long data lines directly from the main switch (if its closer to the gate than the NVR), or run a single data line to another regular 5 port switch, which will act as the extender to the two data-only lines to the 811A and doorbell areas, then have two single-port POE injector wall-warts (about $20 each), nearer to each camera, then simply run a short POE cable to each camera from each of these POE wall-warts.

@mike_201907_662346852388871 There are 2 port PoE extenders available which are powered by PoE+ or PoE++ (PD / powered device) and can power two cameras with PoE+ each for example... Also available as an ruggedized outdorr version...

Yeah, you can totally use a PoE extender with 2 ports for both your front gate camera and the Reolink PoE video doorbell. Just make sure the extender supports the PoE standard your devices use (probably 802.3af or 802.3at). Also, check if it's compatible with your NVR.
