For anyone considering these 3mp bullet Dahuas, they really are amazing cameras. Only snag is that when using the PSS software to record directly to my PC, it only records about 24 hours before deleting the previous days recordings. I have a 2tb drive dedicated to it, so there is plenty of storage available. I have not seen any settings that would relate to deleting older files. I have also set the minimum disk allocation in the settings area to the full 2tb of the drive. Does it in both manual and scheduling recordings. Any ideas?
