Product Overview
WizSense Series devices combine Dahua's powerful Analytics+ with an intuitive and easy to use interface. WizSense devices offer Smart Motion Detection and Perimeter Protection functions that focus on human and vehicular images and ignore irrelevant images to capture important video while reducing false alarms. WizSense Series devices provide powerful generalsecurityfor small to medium size businesses at a sensible price.
System Overview
The X81B Series HDCVI DVR offers 4K recording on each HDCVI channel and a host of advanced features and functions. The X81B takes advantage of HDCVI technology for easy integration into existing video security systems while leveraging existing networks, cabling, and cameras. Penta-brid access technology seamlessly records video from HDCVI, AHD, TVI, CVBS, and IP sources simultaneously, plus the DVR delivers 4K resolution on each HDCVI or IP channel.
Functions | 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
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.
Smart H.265+
Smart H.265+ is the optimized implementation of the H.265 codec that uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI,
flexible multi-frame reference structure and intelligent noise reduction to deliver high-quality video without straining the network. Smart
H.265+ technology reduces bit rate and storage requirements by up to 90% when compared to the H.264 video compression standard.
4K Resolution
improves the clarity of a magnified scene to view or record crisp forensic video from large areas.
