Its 1/2.7" CMOS image sensor combined with the 3.6mm fixed lens provides a 90° angle of view, and will provide enough detail in a face to make a positive identification. You'll be covered in total darkness as well with 50m of smart IR that will adjust its infrared night vision levels to compensate for glare on an object that is close to the camera. This HDCVI dome camera can be used with RG59 coax cabling that is commonly installed for analog systems while delivering FULL HD video when used with an HDCVI DVR. With HDCVI technology the line will also carry audio, so all you need is a siamese cable that carries video and power.. Its IP67 rating makes this a great camera to mount indoors or outdoors.
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
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.*
Simplicity
HDCVI technology inherits the born feature of simplicity from traditional analog surveillance system. HDCVI system can seamlessly upgrade the traditional analog system without replacing existing coaxial cabling. The plug and play approach enables full HD video surveillance without the hassle of configuring a network.
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.
Multi-outputs
The camera supports HDCVI and CVBS signal outputs simultaneously with two BNC connectors. Multi-outputs facilitates construction in such situations as debugging through a tester. It also offers the possibility for cooperating with multiple devices including analog matrix or monitor.
Smart IR
The camera is designed with array 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.
Protection
The camera's outstanding reliability is unsurpassed due to its rugged design. The camera is protected against water and dust with IP67, making it suitable for indoor or outdoor environments
