Dahua 16 Channel 5M-N 1080P DVR 1U 2HDD WizSense XVR5216AN

The XVR5216AN-I3 is distinct from the PoC variant (XVR5216AN-I3-16P) in the absence of PoC: cameras are powered conventionally from a separate power supply unit, rather than over the coaxial cable. This makes it the appropriate specification for the many analogue CCTV installations in the UK where cameras are powered from a multi-channel PSU at the head end, a practice that remains common and is not changed by PoC’s availability.

The dual HDD bay is the key storage advantage over single-bay DVRs at the 16-channel scale: 16 cameras recording continuously or at high motion-trigger frequency generate a significant storage load, and the ability to install two hard drives either in RAID 1 for redundancy or as a combined volume for maximum capacity is a meaningful specification benefit. For sites with insurance or regulatory requirements for CCTV retention periods of 28 or 31 days, the dual HDD capacity is often necessary to meet the requirement.

WizSense AI provides human and vehicle detection across all 16 channels, reducing the monitoring and alert management burden of a 16-camera installation to relevant events rather than all motion activity across the complete camera system.

5M-N recording capability provides above-1080P image detail where 5M-N-capable cameras are installed, while 1080P recording matches the specification of Full HD camera installations.

For CCTV installers across London and the UK completing 16-camera analogue installations where conventional camera power, dual HDD storage, and WizSense AI are the system specification without PoC, the XVR5216AN-I3 is the correct recorder specification.
