Review on YESKAMO Repeater Exterder Wireless Security by Justin Gomez

I bought this receiver from the same company that made my cameras as I expected more range. Turns out my NVR doesn't support repeaters.? I contacted customer service to tell me there is nothing they can do and I need to return the product. I've been watching YouTube videos of people using the same program as my NVR. But for some reason my DVR doesn't have a repeater. By the way, I want to know that the funny part is that my cameras can be receivers themselves (pass signal from camera to camera until the signal reaches the NVR). But I can't even do that because my DVR doesn't "support" it. Promote features that don't work.
