8 Channel AHD CCTV Digital Video Recorder

Key Specifications to Consider when buy Dahua or Viewtec DVRs

• Video Compression: Look for H.265 or H.265+ to maximize storage space; older H.264 models are cheaper but less efficient. 
• Resolution Support: Most standard AHD DVRs support 1080p Lite or 1080N for recording, though higher-end models can handle 4MP or 5MP cameras. 
• Remote Access: Modern units typically support remote viewing via mobile apps like XMEYE, Hik-Connect, or DMSS. 
• Output Ports: Standard units include both HDMI and VGA outputs for connecting to monitors or TVs simultaneously
