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

Starlight Technology

For challenging low-light applicaons, Dahua’s Starlight low light
Technology oers best-in-class light sensivity, capturing details in
low light applicaons. The camera uses a set of opcal features to
balance light throughout the scene, resulng in clear images in dark
environments.

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, where a target crosses a
user-dened line and the camera quickly and accurately responds by
triggering an alarm. Working with IVS-enabled IP cameras, the NVR
recognizes and records video that contains IVS data on all IP channels.

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 disk 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.

High Eciency Video Coding (H.265)

The H.265 (ITU-T VCEG) video compression standard oers double the
data compression rao at the same level of video quality, or substanally
improved video quality at the same bit rate, as compared to older video
compression technologies. H.265 oers such impressive compression
by expanding the paern comparison and dierence-coding, improving
moon vector predicon and moon region merging, and incorporang
an addional ltering step called sample-adapve oset ltering.

Environmental

With a temperature range of –40° C to +60° C (–40° 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.
