2 Port POE Extender Comply IEEE 802.3af/at Standard 10,100Mbps, POE Repeater 100 meters(328 ft) Extender 1 in 2 Out for POE IP Camera over Cat5/Cat6 or Better UTP Cables (POE5003)

I bought this to try out and with the hope of saving my self a alot of work running a second cable. It works well but does need some extra configuration on the cameras and recorder. As it did not work as plug and play first time.For me this method worked using a Hikvision NVR a 2 4K camerasPlug camera 1 in only and assign a static IP then remove cam 1 and plug in cam 2 and assign static ip. Then you can plug both cameras back in and goto recorder. Turn off plug and play and select manual adding. fill in the IP address for cams one and two on your chosen channels and both should be displayed. At first I didnt do this and the images on the recorder kept switching between the two cameras possibly due to an IP conflict.Also the device just about fits in a 100x100x50mm junction box. But is quite tight so would recommend a larger boxCannot say how reliable it is because I have only just fitted it

So good I bought two. Ideal in cases where peripherals such as CCTV cameras are too far from the recorder for good results. I used it between my Hikvision Recorder and Hikvision Camera. One thing that should be noted is that there are two main groups of POE. This device uses the full implementation (IEEE 802.3af) Mode A on pins 1/2 (+) and 3/4(-).Some "POE Cameras" use the more limited version using a fixed voltage (typically 24V) - often using a dedicated POE injector. This implementation is typically found using Pins 4,5+ and 7,8- of the RJ45 connector. This type of POE camera is NOT COMPATIBLE with this adaptor. Also remember that the single PORT has a maximum power output of 12.2W. I suspect that the two port version which is marginally larger is limited to about the SAME power split between the ports. Beware if trying to run two 6W cameras.

Simply did not work

Used this in a local community building to enable the daisy-chain connection of 2 or 3 PoE devices where it wasn't possible to install multiple individual network cables back to the main PoE switch. Nice small unit that tucks into a small space (used double sided padded tape) to conceal it.

Does exactly what I needed (allowing me to power two PoE devices with a single PoE/PoE+ injector and router port). Only negative point is it gets quite warm, indicating it's eating a bit of power in the process.

Bought one of these devices in Sept 2021. Needed to run two 100Mpbs Hikvision PoE cameras over a single CAT6 cable. The device appears to have a three port switch within it (one input and two outputs). Worked perfectly, no issues. I found the unit to be small enough to just fit within a large Hikvision camera mounting box / back box.I estimate that the CAT6 cable run from the PoE switch was around 30-40M, the runs from the device to the cameras: 20cm and around 2M.Been working for around 2 weeks now without any issues.

Does what it says - splits single PoE to feed two cameras.Works well. Check the maximum watts available though to avoid over-heating.

Ordered my first one that started smoking within the first 5 minutes of being plugged in. The second one didn’t even power up. The input was plugged in to a 802.3bt compatible switch and the output was plugged in to wireless access point that doesn’t draw anywhere near 30W.
