There is a cable from the camera that goes to a KWorld Video adapter. From this adapter run a USB cable and an audio jack, both of which are plugged into the laptop.
What I need is some software that can show the camera's output on the laptop. At the moment the driver for the adapter is installed, but the adapter isn't recognised by Windows. The leaflet that came with the adapter says it won't work without some software. There is software available from the nest-box maker, but it has to be paid for, and these people have a non-existent budget. I offered to pay for it, but that was refused, so I said I would look for something they could download free of charge. The problem is, I don't have a clue about camera feeds, so I need some help.
