I have neighbors who moved in where the previous owners left their NVR for 2 cameras on the house. They don't have a TV in the room with the NVR and they don't have a monitor at this time. Do most people use a TV or monitor for the NVR or is it common to access/operate it from your LAN? I want to help them get their cameras operating, just wanted to know some options. Maybe getting a monitor would be their easiest solution. Thanks for your input.
