Hi, I am facing an issue in configuring an All in one LCD DVR (model no: SYAE--SA-MF1916AVS). The client had directly purchased the unit from a trade fair in china, it doesn't have any user manual or brand name. we have connected the cameras to the device, but cant find a function to select DVR, while pressing select it just shows four options ie. VGA, SVIDEO, AV, TV. So if someone could help me in this regard it would be very much usefull. Thanks & regards Prasanth ESZES TECHNOLOGIES
