I was using this as a gate monitor, but there was one instance where the power suddenly went off. After that, it has been working fine, but the cause is unknown, so I'm replacing it and no longer need it. I'm just a novice, but could the problem be with the cable? I don't know, so I'm selling it cheap. Also, I may have overlooked something, so please consider it as junk. The set includes a power cable.
