I read these two will work together but I haven't gotten it to work. I have the Swann NVR8-7400 and just bought the RLC-410-5MP camera. The NVR sees the camera but says Invalid PWD. The RLC-410 camera can be connected to via a web browser and the default username/password is admin and password is blank. I had read that all that is needed is a blank password. Is it possible this does indeed need to be set to something other than blank? I do know on the camera that if a password is set it must be 6 characters. Any help would be appreciated.
