Hi there So as the title says, i got a unit of Samsung SNR-3200 NVR for testing. So, i have configured it with a Samsung SND-460 IP camera(motion detection enabled) to see how the recording performance is being done. Well.. everything goes fine to be honest, but when it comes to recording.. It records everything! not motion.. EVERYTHING!(i mean, it's on "always recording"). I went through the NVR manual, and i quite don't understand what it even means(and there is no mention to activate motion recording or whatsoever). I just wanna know how to capture motion on this NVR.. can someone help me with this?
