Review - Dahua Ethernet over Coax Converter/Extender LR1002-1ET/LR1002-1EC

You cannot run more than one camera off a NVR poe port.

You are exceeding the power available.

You need to plug multiple cameras into a switch and then the switch to the WAN/LAN of the NVR

Thanks wittaj, I am only running 1 camera via each seperate port. There are 16 cameras in total and 16 built in POE ports on the NVR.

Oh my bad I got the adapters mixed up lol.

Sure seems like you're exceeding max power output but I cant say why...?

I think the power requirements of 32 EOC devices + plus the wattage of the cams, > ( is greater than) than the total output rating of the NVR.
how long are the runs?
Maybe you could escape with a cheap 5 port

That does make sense. I went ahead and ordered a POE switch. I'm not sure how long but I know they could be upward of 300-400ft on some cams as they coiled about 100ft at the end of some runs

I dont think this one is POE though.

sorry wrong product. but you get the idea.

Does anyone know if the LR1002-1ET can connect to a normal network switch instead of just an IP camera?
I need a new network port at a certain location in the home. There's an existing unused coax point so I was wondering if I could use these cheaper LR1002-1ET/LR1002-1EC pair instead of a MOCA pair.

As a secondary curiosity, I am wondering why there would be a transmitter and receiver, which implies unidirectional conversion. However, that doesn't make sense in my head, as an IP camera uses TCP/IP which is bidirectional. Will it work if transmitter/receiver were reversed?

Edit: Answering my own curiosity: Receiver/transmitter would be required because the power transmitted in one direction.

Yes it works that way. when I got one of these, I tested a lot of different things LOL. One of them was with a 4 port POE switch on the end and I powered 3 cameras and could connect a computer to it and get internet.

It is limited to 100Mbps, so that is something to keep in mind.

POE switch > LR1002-EC > coax > LR1002-ET > non POE device (say a laptop) will it work or will it fry the laptop's ethernet port?

That will work - that was how I tested the speed of the units before I put one in operation. Compliant devices only send power if power is needed.
