    I just bought AVTECH DVR AVC760A, and when enable Motion Detection for Camera, then view recorded video, I see that DVR make record of all 04 channel. It was not need to record all channel with just motion detection in one channle, and it is comsume extra HDD. Please advise how to setup so the DVR only record motion channel Thank you TuanND
