DORI Distance
Note: The DORI distance is a “general proximity” of distance which makes it easy to
pinpoint the right camera for your needs. The DORI distance is calculated based on
sensor specification and lab test result according to EN 62676-4 which defines the
criteria for Detect, Observe, Recognize and Identify respectively.

System Overview
Experience 1080P full HD color video and the simplicity of reusing existing
coaxial infrastructure with HDCVI. The full-color starlight HDCVI camera
presents a high quality color image with rich details even in total darkness
conditions. It offers various fixed lens models with a multi-language OSD
and HD/SD switchable output. It adopts two powerful warm white LED
illuminators, covering an effective range up to 40m(131ft). The LEDs switch
on automatically in darkness to capture detail-packed full-color images
24/7, ensuring anthentic identificaiton of objects. It is an ideal choice for
applications such as schools, retail centers and parking lots.
Functions
Full-color Starlight
The camera adopts F1.0 large aperture lens and 1/2.8″ high performance
sensor. With higher amount of absorbed light and advanced image
processing algorithm, the camera presents an impressive lowlight
performance with an exceptional balance between noise reduction and
the blur of moving object.
Warm Supplemental lights
With two warm supplemental LED lights, the camera is able to provide a
coloful and vivid image even in total darkness. It also provides visible By
default, the camera is set to smart light mode, in which the camera can
automatically adjust the exposure time and light sensitivity simultaneously
to avoid overexposureing of the objects in the image center. Also, the
sensitivity and intensity of the LED lights can be remotely controlled by
OSD menu.
Broadcast-quality Audio
Audio information is used as supplementary evidence in video surveillance
applications. The HDCVI camera supports audio signal transmission
over coaxial cable. In addition, it adopts unique audio processing and
transmission technology that best restores source audio and eliminates
noise, guaran-teeing the quality and effectiveness of collected audio
information.
4 Signals over 1 Coaxial Cable
HDCVI technology supports 4 signals to be transmitted over 1 coaxial
cable simultaneously, i.e. video, audio*, data and power. Dual-way data
transmission allows the HDCVI camera to interact with the HCVR, such as
sending control signal or triggering alarm. Moreover, HDCVI technology
supports PoC for construction flexibility.
