It offers various motorized/fixed lens models with a multi-language OSD and HD/SD switchable output. Its superior image performance and starlight feature as well as the dual-lens deign make the camera an ideal choice for some special application scenarios such as corridor turn, hallway, wall corner, entrance, etc. 

Functions 

Excellent Versatility 

Designed with junction box, the camera is in a friendly installation mode to shorten the mounting process and save accessories and labor cost. Besides, the particular structure makes the camera suitable for the applications of various scenes.

 Dual-lens Feature 

The camera equipped with double lens adopts one-way power supply for dual-way video outputs to save cost and time. Dual-eyeball design makes it possible to monitor two directions via one camera, achieving wider horizon. 

Starlight 

With the adoption of high performance sensor, the camera is able to provide incomparable performance even under extreme lowlight environment. The starlight feature allows more details to be captured and accurate color to be recognized at night or in scenes with limited illumination. 

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, guaranteeing the quality and effectiveness of collected audio information.

Wide Dynamic Range

Embedded with industry leading wide dynamic range (WDR) technology, vivid pictures are achieved even in the most intense contrast lighting conditions. True WDR (120dB) optimizes both the bright and dark areas of a scene at the same time to provide usable video.

Advanced 3DNR

3DNR is noise reduction technology that detects and eliminates random noises by comparing two sequential frames. Dahua’s advanced 3DNR technology allows remarkable noise reduction with little impact to sharpness, especially under limited lighting condition. Besides, the advanced 3DNR effectively decreases the band width and saves the storage space.

Long Distance Transmission

HDCVI technology guarantees long-distance and real-time transmission without any loss. It supports up to 800m for 1080P Full HD video via coaxial cable, and up to 300m via UTP cable.

* *Actual results verified by real-scene testing in Dahua's test laboratory.
