I have a H-View CCTV IP HD POE Camera System. The cameras are connected directly to the DVR. The DVR also has a LAN connection to enable the DVR to upload its imagery to the cloud in order to access it by an app on my smartphone. However when I connect the DVR to my Home LAN it overwhelms the LAN and really slows it down. Has anybody else had this issue and if so what is the workaround? Am I missing something? I would be grateful of any advice.
