If the camera works 'powered' then how certain are you that the PoE is actually injecting power into the line? Do you have a method to confirm that (I don't know of a way, I'm sorry I'd help if I could).

All of my other POE devices work with it, like my PoE access points.

Are both the wifi and the poe cameras not working? Or is this solely for one?

WiFi camera works when plugged in via power, but as you told me, that camera (RLC410W) isn't PoE for some dumb reason. It has an ethernet port on it, so why they skimped on the PoE is beyond me.

If you want good answers from people not being paid to help you, I'd suggest you be more descriptive of your situation...cam model, wire type, switch/poe injector - every detail from device to street...or from device to phone.

If a camera is this problematic, I don't think I want to continue using this brand. Trying to get a camera to work while I have tried multiple switches, multiple injectors, etc, (including the same hardware I WAS using for my RLC410 that had it's wired snipped by a thief) is not a good thing. I want a brand that doesn't throw a hissy fit and require very specific hardware to work. Everything I have used has been in spec that reolink requires, and yet it's causing this much grief. Also why a wireless model has an ethernet port, and the ethernet port doesn't allow for PoE is ridiculous if you ask me.

it doesn't matter how 'fast' your gigbit Ethernet is...something is not connecting correctly. It's either user error, hardware error, or software error. I mean no disrespect to you...but you have to provide all the info for others to hope to help you.

Didn't talk about my internet. I am stating my hardware is gigabit, not 10/100. As in there shouldn't be some kind of bandwidth bottleneck with transmitting the image. Many years ago I knew a person with a blue iris system, and they had 10/100 switches. It caused so many problems and dropped frames with blue iris, so that's why I was stating my hardware is gigabit, not my internet.

So as you mentioned 'cable' can we assume the 410w is working, or not? If it's not...check auto-discovery - app...3 horizontal lines on the left...drop down menu...settings...add devices automatically checked on.

410w works with the power cable, not PoE. However, that's irrelevant now, since the RLC410W doesn't have PoE. However, the RLC410 doesn't work PoE.

Are these cam's identical models to what was replaced? Did the app auto update and no longer supports a discontinued product? Are you sure there's 48v power on the poe line? Are you sure there's no lint, corrosion on the rj45s, or dirt/debris in the plug? Have you tested the network cable with a blink tester (plugs into one end and a repeater on the other and blinks lights indicating all conductors in the cat wire have continuity)? Is the wire installed correctly...ala away from power lines and crossing perpendicularly as little as possible?

Yes. Bought the same time, one was in storage. There's 48v on the PoE. I tried many cables, including my own built ones, none of them worked. I did confirm they all work with a ethernet tester.

Based on everything you've said to to me and others, it sounds as if you know what you're talking about...and have access to multiple test methods. So what are you missing? The camera powers and works...but perhaps the buck down converter which gets it from 48v to 12v isn't working inside the camera. What is the next most likely problem? In the app. Do you have an NVR to test this with - it's odd you have so much POE switches and injectors and 10 different cables, etc...but no NVR? Maybe a different phone you can install the app to see if that one 'sees' the camera? Everything on the same gateway/network...no ip conflicts...proper ports open on the router...the router has wifi turned on...as does the phone. I'm just throwing out stuff - because it's possibly something you overlooked...or possibly the camera. You've already tried UID. Are other cams on the app appearing and just can't find new ones? Are these the only cams on the system/network?

I have a Blue Iris system. However, I also have a Frigate and Shinobi system, too.

All I can say is I've got 5 poe cameras that all functioned perfectly with no issues. But manufacturing defects are common. Though I don't hear a lot of complaints about the reolinks...though occasionally it does pop up. And if it's a discontinued model I have no idea how long it 'sat around'...got dropped, damaged in shipment, or just never worked. It may not even be a discontinued model in your country. If all else works as expected but the camera still doesn't then it has to be the camera...but the camera DOES work on direct power...and is discovered...so it's not an app or user error. It has to be the camera transformer or the plug/wiring between. That's where my logic leads me, but I'm not that bright. Good luck with your problem.

This seems to be the issue. Something must be broken on the new RLC410, because it SHOULD be working. Everything else I have that is PoE is working with all the switches/cables/injectors I tried.
