Hello, I recently moved into a new property and it has ZOSI security cameras (model: ZG1062B). The DVR disk broke a few years before I bought the house, so the sellers bought a new DVR (model number ZR08VN) and left it in the box and told me I just had to connect the wires and I was good to go. Ive done that, set up the box, connected all wires, and although the box works there is no signal from any camera.
The seller then said that if I connect the audio cable the cameras will work. This doesnt sound right, but there isnt any cable that connects to the audio IN on the DVR box.
