have dahua 4208 and we've been having some ISP issues. 4 cameras. once network is working all cameras record fine and motion detector works, but once my network goes down everything stops recording - no motion detection either -- and I have no record of anything. Is there a setting or something else I am missing. Thanks for any assistance you can provide.
