NVG in our line of work means Night Vision Goggles. And they work the same way the IR cameras work during a ghost hunt. I used to use NVGs in the early days, but a thermal camera works so much better for live viewing. Using night vision or IR cameras works great when used with a recorder device like a tape, or DVR, for later review.
Wireless security cameras do not have wires. They transmit the video to the DVR or monitor. Nothing should be blocking the line of sight from the camera to the monitor, otherwise it will not work.
