HD Cameras Connection Diagram

HD video signals transfer over coax cables to the DVR (Digital Video Recorder). HD Camera are powered by plugging in the power supply. The DVR then converts the analog signal to digital, compresses it then stores it on a Hard Disk. The information is built into the DVR to handle scheduling, motion detection and digital zooming. To view the footage, monitors are connected to the DVR or you could use an internal network for viewing on PCs. DVR's can also be set up to broadcast over the internet and set up to be password protected. The video for all of the cameras are transmitted as one stream, one IP address.

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.* Audio input is available for some models of HDCVI cameras.

Long Distance Transmission

HDCVI technology guarantees real-time transmission at long distance without any loss. It supports up to 800m(1080P)/1200m(720P) trans-mission via coaxial cable, and up to 300m(1080P)/450m(720P) via UTP cable.**Actual results verified by real-scene testing in Dahua's test laboratory.


HDCVI technology inherits the born feature of simplicity from traditional analog surveillance system, making itself a best choice for investment protection. HDCVI system can seamlessly upgrade the traditional ana-log  system  without  replacing  existing  coaxial  cabling.  The  plug  and play approach enables full HD video surveillance without the hassle of configuring a network.

Smart IR

The camera is designed with microcrystalline LED IR illumination for best lowlight performance. Smart IR is a technology to ensure brightness uniformity in B/W image under low illumination. Dahua’s unique Smart IR adjusts to the intensity of camera's infrared LEDs to compensate for the distance of an object, and prevents IR LEDs from overexposing images as the object come closer to the camera.


The camera supports multiple video formats including HDCVI, CVBS and other two common HD analog formats in the market. The four formats can be switched over through OSD menu or by PFM820 (UTC controller). This feature makes the camera to be compatible with not only HCVRs but also most end users’ existing HD/SD DVRs.

Multi-language OSD

OSD menu provides multiple image adjustments and function settings to meet the requirements of different monitoring scenes. The OSD menu includes configurations such as backlight mode, day/night, white balance, privacy mask and motion detect. The camera supports 11 languages for OSD menu, namely, Chinese, English, French, German, Spanish, Portuguese, Italian, Japanese, Korean, Russian and Polis
