Dahua NVR2216-16P-4KS3 16CH 4K NVR with 16-Port PoE and 2 HDD Bays

Dahua NVR2216-16P-4KS3 16CH 4K PoE Network Video Recorder

The Dahua NVR2216-16P-4KS3 is a professional 16-channel network video recorder designed for IP surveillance systems that need centralized recording together with convenient camera power and network connectivity.

With 16 built-in PoE ports, the NVR can connect compatible PoE IP cameras directly, reducing the need for a separate PoE switch in many installations. It supports IP cameras with resolutions up to 12MP, making it suitable for modern high-resolution surveillance systems.

16 Built-in PoE Ports

One of the main advantages of the NVR2216-16P-4KS3 is its integrated 16-port PoE switch.

The PoE ports support IEEE 802.3af/at, allowing compatible network cameras to receive power and network connectivity through the same Ethernet cable. The total PoE output is up to 130W, while the maximum output of a single port is 25.5W.

This helps simplify installation and reduce cable requirements in IP camera system

16-Channel IP Camera Support

The recorder provides 16 IP camera channels and supports camera resolutions up to 12MP. This gives installers flexibility to build surveillance systems using different Dahua IP camera resolutions depending on the application.

4K HDMI Output

For high-detail surveillance viewing, the NVR supports HDMI output up to 3840 × 2160, allowing compatible 4K displays to show high-resolution live views and recordings.

It also provides VGA output for additional display compatibility.

2 HDD Bays for Extended Recording

The NVR includes two SATA HDD bays, with each drive supporting up to 20TB, subject to environmental conditions.

Using two hard drives can provide a larger storage capacity for surveillance footage and is particularly useful for systems requiring longer recording retention.

Smart H.265+ Compression

The NVR supports Smart H.265+, H.265, Smart H.264+, H.264 and MJPEG video compression.

Smart compression technology helps optimize storage and network bandwidth, which can be especially valuable when recording multiple high-resolution IP cameras.

Intelligent SMD Plus

The NVR supports 4-channel SMD Plus by recorder, helping classify motion targets as humans or motor vehicles and filter out irrelevant triggers.

This intelligent filtering can reduce false alarms caused by environmental movement such as leaves, rain and changing lighting conditions.

Compatible Dahua cameras can also provide camera-side AI functions such as perimeter protection and SMD Plus.

High Network Bandwidth

The NVR supports up to 144 Mbps incoming bandwidth, 144 Mbps recording bandwidth and 72 Mbps outgoing bandwidth when AI is disabled.

When AI is enabled, the supported bandwidth is reduced to 72 Mbps incoming, 72 Mbps recording and 36 Mbps outgoing, providing flexibility for AI-enabled surveillance deployments.

Playback and Remote Monitoring

The NVR supports playback of up to 16 channels and provides multiple playback modes, including general playback, event playback, tag playback and smart playback.

Remote access is supported through iOS and Android devices, allowing users to monitor compatible surveillance systems remotely.
