Azhar. I have Dahua DVR with 2 TB Hardisk and 2 MP cameras but the system wont record more than 23 days. How Can I change resultion of some less priority cameras to increase the recording number of days. Thank You.

Go to settings÷camera÷encode÷select channel÷sub stream÷resolution÷according to you camera if 2 mp you can make 1.3 if 5 you can make 2 mp
