Hikvision 16-ch 1U 16 PoE 8K NVR

The Hikvision DS-7616NI-M2/16P is a 16-channel network video recorder (NVR) built for medium to large IP camera systems — think multi-site offices, retail units or warehouses rather than a single-camera home setup.

What it actually does

It records footage from up to 16 IP cameras, decoding up to 16 channels at 4MP simultaneously so you can watch multiple feeds live without stutter. Incoming bandwidth tops out at 256 Mbps, which covers a full set of higher-resolution cameras without the recorder choking on the data.

Power and wiring

This model has 16 built-in PoE ports — Power over Ethernet, meaning one cable per camera carries both power and video, so you skip separate power leads and injectors. That simplifies installation considerably compared to a non-PoE NVR paired with a switch.

Storage and compression

Two SATA interfaces let you fit hard drives for local recording — plan drive size around how many cameras and how many days you want to keep. Video compression options include H.265+, H.265, H.264+ and H.264, with H.265+ giving the smallest files for the same quality, useful if you're storing weeks of footage rather than days.

Audio

Up to 8 IP speakers can be added, useful for alarm announcements or two-way audio zones across a site.

Before buying, check your cameras are IP (not analogue) and confirm your camera count and resolution fit within the 16-channel/4MP decoding limit.
