System Overview

The Dahua Network Security System provides all the components to
quickly install, congure, and employ a complete video surveillance
soluon. The IP cameras oer the clarity of 4 MP video, and the

NVR oers built-in moon detecon algorithms, alarm triggers, and
customized recording modes. The NVR also features Plug and Play
technology to connect quickly to cameras on the same network. Each
component accepts a PoE power supply to facilitate installaon.

Funcons

Intelligent Video System

IVS is a built-in video analyc algorithm that delivers intelligent funcons
to monitor a scene for Tripwire violaons, intrusion detecon, and
abandoned or missing objects. A camera with IVS quickly and accurately
responds to monitoring events in a specic area. In addion to scene
analycs, the camera detects and captures a snapshot of human face in a
dened area within a scene, and oers tamper detecon by recognizing
a dramac scene change and generang a warning message to inspect
the camera.

Working with IVS-enabled IP cameras, the NVR recognizes and records
video that contains IVS data on all IP channels. The NVR records standard
intelligence at-the-edge features, as well as premium IVS features that
detect abandoned or missing objects, Tripwire violaons, and intrusion
violaons.

Smart IR

With IR illuminaon, detailed images can be captured in low light or
total darkness. The camera's Smart IR technology adjusts the intensity of
camera's infrared LEDs to compensate the distance of an object. Smart
IR technology prevents IR LEDs from whitening out images as they come
closer to the camera. The camera's integrated infrared illuminaon
provides high performance in extreme low-light environments up to
30 m (98 ).

Flexible Recording

The NVR oers a variety of congurable recording opons and schedules
that saves HDD space and acve monitoring me. The NVR monitors
incoming video and can be programmed to record if moon is detected
or if an alarm is triggered. The NVR can also be programmed to record on
a schedule or at dierent intervals. The recording opons and schedules
can be set for each individual camera or copied to all cameras.

Smart H.265+

Smart H.265+ is the opmized implementaon of the H.265 codec that
uses a scene-adapve encoding strategy, dynamic GOP, dynamic ROI,
exible mul-frame reference structure and intelligent noise reducon to
deliver high-quality video without straining the network. Smart H.265+
technology reduces bit rate and storage requirements by up to 70% when
compared to standard H.265 video compression.

Environmental

With a built-in heater and a temperature range of –30° C to +60° C
(–22° F to +140° F), the cameras are designed for extreme temperature
environments. The cameras, subjected to rigorous dust and water
immersion tests, are cered to the IP67 rang making them suitable for
demanding outdoor applicaons.

The NVR features an operang temperature of -10° C to +55° C (+14° F to
+131° F).

Interoperability

The camera and NVR conform to the ONVIF (Open Network Video
Interface Forum) specicaon, ensuring interoperability between
network video products regardless of manufacturer.

1. The DORI distance is a measure of the general proximity for a specic classicaon to help pinpoint the right
camera for your needs. The DORI distance is calculated based on sensor specicaons and lab test results
according to EN 62676-4 , the standard that denes the criteria for the Detect, Observe, Recognize and
Idenfy classicaons.
