Description
The WizSense Series devices integrate Dahua’s advanced Analytics+ with a user-friendly interface, providing cutting-edge solutions in video surveillance. These devices feature Smart Motion Detection and Perimeter Protection, specifically targeting human and vehicle images while filtering out irrelevant content, thereby capturing critical footage and minimizing false alarms. Ideal for small to medium-sized businesses, WizSense Series devices deliver robust security at an economical price point.
System Overview
The X81B Series HDCVI DVR offers 4K recording on each HDCVI channel, along with a suite of advanced surveillance features. Leveraging HDCVI technology, the X81B easily integrates into existing video security systems, utilizing current networks, cabling, and cameras. Its Penta-brid access technology allows for simultaneous video recording from HDCVI, AHD, TVI, CVBS, and IP sources, delivering 4K resolution across all HDCVI or IP channels.
Functions | Perimeter Protection
Dahua Analytics+ encompasses Tripwire and Intrusion functions, facilitating automation in restricted access areas with object-type-specific tripwires. Perimeter Protection decreases pixel dependency for object detection, enhancing accuracy and reducing false alarms caused by environmental factors like lighting, weather, trees, or animals.
Smart Motion Detection
Part of Dahua’s Analytics+ suite, Smart Motion Detection refines alarm precision by analyzing scenes for human or vehicle activity, excluding irrelevant motions from trees, leaves, or weather conditions, ensuring alarms are only triggered by genuine threats.
AI Coding
The AI Coding feature prioritizes recording emphasis on human and vehicular elements within captured video scenes. Utilizing a constant bit rate (CBR), it dynamically allocates higher bit rates to target objects while reducing the bit rate dedicated to the background. AI Coding optimizes storage and bit rate requirements, achieving up to a 50% reduction compared to the H.265 standard.
Smart H.265+
Smart H.265+ is an advanced variant of the H.265 codec, employing scene-adaptive encoding strategies, dynamic GOP, dynamic ROI, flexible multi-frame reference structures, and intelligent noise reduction to deliver exceptional video quality without overtaxing the network. This technology reduces bit rate and storage needs by up to 90% compared to H.264 criteria.
4K Resolution
The HDCVI DVR captures 4K resolution on each HDCVI and IP channel, a significant leap in image processing technology offering four times the resolution of standard HDTV 1080p cameras. This level of detail in 4K resolution enhances the clarity of magnified scenes, allowing for precise forensic video analysis from expansive areas.
