ban85 0 Posted February 16, 2018 Hi everybody! I have a mystery problem. I have 2 different dvr boards. 1st one is an 1080n 8ch Ahd dvr board, the another board is a better 1080p hybrid dvr board (AHB7008T-GS-V3) As i know that's from XM company, china. The problem is that the pre record function doesn't work with both boards. I tried everything: Change encode settings, record settings, motion detection setup, change hdd, but nothing. My main settings: Motion detection recording, 5sec pre rec, 10sec post rec. Had anybody issues about that? I don't think both board are faulty. Please help me if you have any idea! Thank you!
