DAHUA Network Video Recorder Lite 2HDD -nvr4216-16p-4ks3 16 Channel 16poe 1u

The NVR4000-4KS3 model of the Lite Series NVR is favored for its
outstanding performance. It supports 4K resolution for scenes that
require highly detailed images, and can serve as the edge, central, or
backup storage with an intuitive shortcut menu for remote
management and control. This NVR also features Smart Motion
Detection (SMD) by recorder, which can distinguish target vehicles and
humans from ordinary ones in real-time. When an IPC is connected to
the NVR, a variety of AI functions become available such as face
detection, perimeter protection, and people counting. This NVR is
both cost-effective and easy-to-install, making it ideal for a wide range
of applications such as for cities, transportation, education and
finance.

SMD Plus
With intelligent algorithm, Dahua Smart Motion Detection technology
can categorize the targets that trigger motion detection and filter the
motion detection alarm triggered by non-concerned targets to realize
effective and accurate alarm.

Face Detection by Camera
Face detection is to detect if there is any human face appearing in the
video. This technology adopts a deep learning algorithm to support
face detection, tracking, optimization and capturing, and then output
the best face snapshot.

Face Recognition by Camera
Dahua Face Recognition technology extracts the features of captured
faces and compares them with that in face database.

Perimeter Protection by Camera
Automatically filters out false alarms caused by animals, rustling
leaves, bright lights, etc. Enables system to act secondary recognition
for the targets. Improves alarm accuracy.

Stereo Analysis by Camera
With deep learning algorithm and 3-dimensional scene information,
Dahua Stereo Analysis technology can recognize people's behaviors,
such as fall detection, violence detection, stay detection, and space
exception, and then generates alarm signals and triggers linkage.

Heat Map by Camera
Dahua heat map technology is used to display the crowd density and
people appearance probability. Export and display the crowd status by
different colors. Generally, the crowd status is the statistics of people
quantity in space and time dimensions.
