Hello! I want to start by saying I am completely new to CCTV and just started researching on the subject. One question I could not find an answer on the internet is: Can I set up a DVR surveillance system with IP cameras without a router? As in, just plug the Ethernet cable directly in the DVR? Also can I set everything up in DVR without a PC, only using the mouse and remote control on a TV? The problem is, I don't own a laptop and I can't just pack my PC and go there with it. I do have a TV there and access to the internet. Thank you in advance!
