      Dahua 5MP HDCVI Security System

      The Dahua HDCVI Security System provides the components to quickly install a video surveillance solution. The HDCVI cameras offer the clarity of 5 MP video with a 16:9 aspect ratio, and the HDCVI DVR offers built-in motion detection algorithms, alarm triggers, and customized recording modes. The cameras and the HDCVI DVR supports multiple video outputs making the kit compatible with many existing systems. The kit features Dahua's HDCVI technology that leverages an existing coaxial infrastructure, saving time and costs from running networking and power cables.

      Key Features:

      HDCVI Cameras
      • 1/2.7-in. 5 MP Progressive-scan CMOS Sensor 
      • 5 MP at 25 fps Maximum Resolution, 2.8 mm Fixed Lens 
      • 16:9 Aspect Ratio for no Image Stretching 
      • Maximum IR Length 30 m (98.43 ft), Smart IR 
      • IP67 Ingress Protection 
      HDCVI DVR 
      • 2 TB Pre-installed Hard Disk Drive 
      • Four-channel Penta-brid Recorder, Dual-streaming 
      • Smart H.265+ and Smart H.264+ Dual Codec 
      • 5 MP at 12 fps or 4K at 7 fps Recording Resolution on All HDCVI Channels 
      • AI Coding Technology for High-quality Human/Vehicle Video 
      • Perimeter Protection and Smart Motion Detection (SMD)
      Perimeter Protection

      Dahua Analytics+ includes Tripwire and Intrusion functions that offer custom tripwires based on object type for automation in limited access areas. Perimeter Protection requires less pixels to detect an object to deliver improved accuracy and decreased false alarms due to lights, weather, trees, or animals. 

      Smart Motion Detection

      The Smart Motion Detection, a component of Dahua's Analytics+ technology, improves alarm accuracy and decreases the number of false alarms. The advanced SMD algorithm analyzes a scene for human or vehicle motion, while filtering out other motion due to trees, leaves, animals, weather, and triggers an alarm when detected.

      AI Coding

      The AI Coding function puts recording emphasis on human or vehicular objects in the video scene. This technology, based on constant bit rate (CBR), dynamically allocates increased bit rate to the target object while reducing the bit rate allocated to background objects. AI Coding reduces bit rate and storage requirements by up to 50% when compared to the H.265 video compression standard.

      Flexible Recording

      The HDCVI DVR offers a variety of configurable recording options and schedules that saves HDD space and active monitoring time. The HDCVI DVR monitors incoming video and can be programmed to record if motion is detected or if an alarm is triggered. The HDCVI DVR can also be programmed to record on a schedule or at different intervals. The recording options and schedules can be set for each individual camera or copied to all cameras.

      Long Distance Transmission

      HDCVI technology guarantees real-time transmission over long distances without loss of video quality. HDCVI devices provide the same resolution as most IP network camera systems using existing RG-59, RG-6, or CAT 6 UTP cabling.

      Multi-format Support 

      The camera and HDCVI DVR supports multiple video formats including, HDCVI, CVBS, AHD, and TVI. The camera can switch between these four formats via the OSD menu or the switch located on the video output cable making the camera compatible with not only HDCVI DVRs but also most existing HD/SD DVRs. The HDCVI DVR automatically recognizes the incoming signals of each attached camera without any setup, making installation easy and operation convenient.

      Environmental

      With a temperature range of –40° C to +60° C (–40° F to +140° F), the cameras are designed for extreme temperature environments. The cameras, subjected to rigorous dust and water immersion tests, are certified to the IP67 rating making them suitable for demanding outdoor applications. The HDCVI DVR features an operating temperature of –10° C to +55° C (+14° F to +131° F).
