System Overview
The Dahua Video Doorbell Network Security System provides all the
components to quickly install, congure, and employ a complete video
surveillance soluon. The Video Doorbell oers 2 MP video and two-way
communicaon, the IP cameras oer the clarity of 4 MP video, and the
NVR oers built-in moon detecon algorithms, alarm triggers, and
customized recording modes. The Video Doorbell and the network
cameras connect easily to the NVR for total system recording. In addion,
the Video Doorbell and the NVR are compable with the Dahua DMSS
mobile applicaon to view live video, congure and acknowledge alarms,
and share video with authorized users.
Funcons
WiFi Video Doorbell
The DHI-DB11 WiFi Video Doorbell oers Passive IR moon detecon
and transmits video and audio to a mobile phone for remote visual
conrmaon and communicaon with visitors. The DHI-DB11 oers
high-resoluon video ideal for surveillance at homes and in small retail or
dining establishments.
DMSS Compability
DMSS is a mobile surveillance applicaon that includes alarm push
funcons and P2P discovery. The applicaon is available for IOS devices
(in the Apple App Store) and for Android devices (in the Google Play
Sore). DMSS oers 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 applicaons, Dahua’s Starlight low light
Technology oers best-in-class light sensivity, capturing details in
low light applicaons. The camera uses a set of opcal features to
balance light throughout the scene, resulng in clear images in dark
environments.
Intelligent Video System
IVS is a built-in video analyc algorithm that delivers intelligent funcons
to monitor a scene for Tripwire violaons, where a target crosses a
user-dened line, and for intrusion violaons where a target enters or
exits a dened 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 illuminaon, 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 illuminaon
provides high performance in extreme low-light environments up to 30 m
(98 ).
Flexible Recording
The NVR oers a variety of congurable recording opons and schedules
that saves disk space and acve monitoring me. The NVR monitors
incoming video and can be programmed to record if moon is detected
or if an alarm is triggered. The NVR can also be programmed to record on
a schedule or at dierent intervals. The recording opons and schedules
can be set for each individual camera or copied to all cameras.
High Eciency Video Coding (H.265)
The H.265 (ITU-T VCEG) video compression standard oers double the
data compression rao at the same level of video quality, or substanally
improved video quality at the same bit rate, as compared to older video
compression technologies. H.265 oers such impressive compression
by expanding the paern comparison and dierence-coding, improving
moon vector predicon and moon region merging, and incorporang
an addional ltering step called sample-adapve oset ltering.

1. The DORI distance is a measure of the general proximity for a specic classicaon to help pinpoint the right
camera for your needs. The DORI distance is calculated based on sensor specicaons and lab test results
according to EN 62676-4 , the standard that denes the criteria for the Detect, Observe, Recognize and
Idenfy classicaons.
