Revotech Gigabit 2 Port POE Extender, IEEE 802.3af/at PoE+ Standard, 10,100,1000Mbps, POE Repeater 100 Meters(328 ft), Extender 1 in 2 Out, Power Supply for PoE Camera/PoE Device (POE5003-G)

Got it working

I had an IP camera on a cat-6 cable that was 520' long. The camera would start to boot up but was only receiving 3.5 watts and needs 5.5w to operate. I found this non-powered mid-span repeater and for the price, thought it was worth a shot. I skeptically spliced the device into my cable (RJ45 Mod ends) about 225' into the 520' cable. When I reconnected the cable, I saw the lights on the REVOTECH light up and by the time I could get the scissor lift over to the camera (it's mounted 35' up) it was up and operational. I have already purchased more of them for another camera at this same site and for future use. FYI...I was connected to a POE switch at the headend that supplied 25w. The camera auto-negotiates the wattage it needs, in this case 5.5w. The camera tester (Trend networks RV171000) indicated I had 12.5w of available power at the far-end. If the cable passes all tests but fails on length, this will probably fix your issue.

As a Network Engineer - knowing better than to allow any WIFI noise in the system..This device is perfect for long runs or runs with suspect or compromised cabling.It's like a remote switch.. and I suspect since this device is only two ports out.. that collisions (streaming or other error correction) won't be an issue of reliability or stability.

Gigabit version - 2 port. Acts like POE powered 2 port gigabit switch- with POE passthru. I haven't used it for POE power (on the outputs) , but have not doubt it will function as such. I used POE power switch on one end and (this) POE extender on other side of single ethernet line to avoid running another ethernet cable. I'm getting full duplex gigabit speeds on both ports from the extender. No need to plug in the extender, which is convenient , since it uses the POE power input. Device is very compact. Overall, nice way to avoid running more ethernet cables if you >already< have POE power to input to extender.

I used this device to split a 30W PoE+ link into two 15W PoE links to provide power and data to an Axis camera and an Ubiquiti access point. It worked exactly as expected. Normally, I would not design a new network around a device like this, but for an existing network it can be a real time saver.This device returned to normal operation after the switch was intentionally powered off and then back on.One might take this for granted, but there is a similar device being sold on Amazon (it is all white) which does not!

I have an application with a PoE camera, as well as a cable going to a sprinkler box having a 12v DC PoE splitter (which powers 2 sonoffs and 4 motorized ball valves), so very little idle current. Even with no DC devices, this extended will reliably power the camera, but not reliably power the 12v splitter. And I have a second one that does the same thing (seems worse when it's above 80° out). So this isn't reliable for powering even low current 12v DC Splitters.

Easy to use but appears a little light weight for outdoor use.

I bought one of these because I only ran one LAN cable to a TV location and realized I needed 2 connections - one for the smart TV and one for the TiVO box. I only used POE power to power this splitter. Both devices are just Ethernet and don’t require POE power. Cheaper than installing a switch and using another outlet.Seems to work fine. More stable connection than using the Wi-Fi for SmartTV. I want to keep Wi-Fi bandwidth free for phones, tablets and laptops.
