LINOVISION Mini 2 Port POE Extender IEEE 802.3af/at POE Repeater Up to 1000ft Power Over Ethernet Over Cat5/6 Cable, POE Splitter to 2 POE Devices Like IP Cameras, IP Phone

My POE switch has only one port available and total power wise its running 50% below max. Tested it with two Hikvision fixed lens cameras that pulled about 5 watts each. Power cycled, about six separate times, the POE LAN port that is connected to the IN on this unit (PoE Extender02), every time the NVR system reconnected both cameras without a problem. Didn't try to replicate rookie mistakes of running at max spec for this unit as it always is safe and saves time to run under specs, why? cause functionality is always the premium.

I needed to add a second POE camera in a location where I already had one. I really didn't want to run another Ethernet cable, so I purchased this to run both POE cameras off the one cable and it works! I was so happy that the POE could power this switch along with both cameras. Not only that, but there is about 150-200' of CAT5e cable between the primary POE switch and this switch - and it still works! Couldn't be happier.

I needed to add a camera to the garage but did not like the idea of running another wire to the switch. This device allows you to use an existing wire to add another camera. Apparently, the voltage coming from the POE switch is enough to support more than one camera. I'm very happy to have run into this extender.

I'm a network engineer of 30 years and tried this product on multiple POE products including Unifi switches. The lights never came on, the product never worked. For me it was a waste of money and time; I would recommend avoiding this product.

Ordered two units, one was DOA. Other one works to power two ip cameras, but after a day both went offline. Had to reset Poe switch. Went offline again a day later.They offered replacement or refund with no hassle so I gave 4 stars for that.

Went thru several brands/models of these before I found this one that worked. Using it to power a PoE camera and also a second PoE to 12V adapter for an extra IR floodlight off the same network drop. Works great!

I've bought 3 of these for my home camera network, and today only 1 of them is still working reliably. The units seem to overheat extremely easily and over time, this causes power and connection issues.For the two that no longer work, for a while I would be able to get them functional by unplugging them from the POE switch and reconnecting them, but eventually that no longer worked. Power and tx rates became spotty and the cameras would not power up or connect properly.When the first one went out, I bought the 3rd one thinking that I simply got a bad one. But turns out they all have this issue, as the 2nd one went out and the 3rd one started showing signs of the issues as well. I have since upgraded the critical ones to a more reputable brand and can only use the 3rd one in a diminished, non-data capacity.I would recommend saving the headache and spending the extra $5 or $10 for a better constructed unit.

This device works as advertised, it will take a single PoE line in and provide two PoE lines out. HOWEVER: make sure you mount this device where you can easily get to it. I have installed two of these units on separate projects, and in the event of power loss, they will not reset properly. Both ports turn on at the same time and neither one will grab an IP address. The only remedy I have found is to unplug one of the cameras, wait about five seconds, then plug it back in. At that point, both cameras will obtain IP addresses again.
