I have 4 cameras, 2-RLC-410-5MP, 1-RLC-410WS and 1-RLC-510A. I plugged them all into my RLN8-410 NVR. Only 2 cameras appeared, the 2 RLC-410-5MP. The other two cameras had to be plugged into the router. The 2 plugged into the router were given 5 digit IPs while the two that automatically showed up on the NVR were assigned 8 digit IPs. Apparently the 410-5MPs work well with the NVR but unfortunately are no longer available. Anyone have any recommendations for two cameras that will automatically show up on the NVR as I have have no plugs left on the router. Also does anyone know why I can't download from my NVR to a laptop on the same network? I can see and play the clips but can't download them. Any help appreciated.

@md Thans for the info.

Looking for some basic answers for the RLN8-410 NVR. If I want to download a recorded file to a USB drive do I need to plug it in the back? If I have an external drive will it takeover once the internal drive is full? What do I need to be able to download from the NVR to my laptop that is connected to the same router? I can access the NVR but when I try to download I get an error about the drive letter. Is there a place I can assign it a letter or is something else keeping me from downloading it.

I have RLC-510A cameras which are POE. Do I need to use the power supply that came with them or just use the ethernet?
