System Overview

The Dahua Video Doorbell Network Security System provides all the
components to quickly install, congure, and employ a complete video
surveillance soluon. The Video Doorbell oers 2 MP video and two-way
communica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 Video Doorbell and the network
cameras connect easily to the NVR for total system recording. In addion,
the Video Doorbell and the NVR are compable with the Dahua DMSS
mobile applicaon to view live video, congure and acknowledge alarms,
and share video with authorized users.

Funcons

WiFi Video Doorbell

The DHI-DB11 WiFi Video Doorbell oers Passive IR moon detecon
and transmits video and audio to a mobile phone for remote visual
conrmaon and communicaon with visitors. The DHI-DB11 oers
high-resoluon video ideal for surveillance at homes and in small retail or
dining establishments.

DMSS Compability

DMSS is a mobile surveillance applicaon that includes alarm push
funcons and P2P discovery. The applicaon is available for IOS devices
(in the Apple App Store) and for Android devices (in the Google Play
Sore). DMSS oers an easy to use interface to quickly add Dahua devices,
including network cameras, NVRs, HDCVI DVRs, Video Intercom, and
alarms.

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 for intrusion violaons where a target enters or
exits a dened perimeter. 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.

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.
