Mendocino

Dear good, I am new to the forum, I have several Hikvision DVRs managing with the IVMS 4200, all analogs are mostly DS-7216HGHI, I have several problems with motion recordings. I have seen that I have recordings where there is nobody (There is no movement) but I have the recordings, with which when looking for an event it becomes impossible, all the cameras are by motion detection, I have lowered the sensitivity but it follows me recording. I need to know how I can see what is recording the sector that detects movement in the camera. The cameras that I use are the DS-2CE16DOT-IRF. I have seen that some is activated a box where the movement is (attached photo)
