Hi All, Firstly thanks for your assistance. I'm a long time lurker and first time poster. I have spent quite a lot of time reading through the Wiki and Cliffs notes (very helpful). Feel free to move this thread if I've posted in the wrong part of the forums. I'm assisting with installing cameras at my parents house and didn't want to waste their money/time. I'm based in Australia and have decided on 6 x HDW-2231RP-ZS. I've attached a diagram illustrating the intended layout including NVR, PoE switches and powerline adapters. The NVR and powerline adapters have already been purchased. Based off the diagram provided are there any major concerns in relation to compatibility of the components? My concerns involve the bandwidth required for 3 cameras over the powerline adapters (motion detection, not 24/7 recording, 10-15 FPS). I am unsure of the bandwidth requirements for 3 cameras to be transmitted over the gigabit powerline adapters from the garage to the house where the NVR is located. From brief testing performed I believe the signal on the powerline adapters are good and in excess of 50mbps. Additionally is a router required (on top of the unmanaged PoE switches) to provide IP addresses for all of the devices considering this setup will not be connected to the router/internet? Cheers for your help.
