What is Dahua WizSense?

WizSense is Dahua's residential and SMB AI surveillance platform. It uses a dedicated independent AI chip and deep learning algorithms to detect humans and vehicles with up to 99.5% accuracy while filtering out possums, insects, headlights, and wind — reducing false alarms by up to 90% vs standard motion detection. Core technologies include SMD 4.0, AI SSA, Quick Pick, and AI Coding (H.265+).

How does SMD 4.0 reduce false alarms in Australian conditions?

SMD 4.0 classifies every detected motion as human, vehicle, or irrelevant. Irrelevant objects — possums, birds, insects, leaves, rain, headlights — are filtered before any notification is generated. You receive push alerts only for genuine human or vehicle events within your defined detection zones.

What's the difference between WizSense and WizMind?

WizSense focuses on human and vehicle detection with smart alerts, Quick Pick search, and AI SSA — ideal for residential homes and small businesses. WizMind adds enterprise analytics: face recognition, people counting, ANPR, heat maps, and business intelligence — designed for commercial, retail, and government environments.

What's the difference between WizSense and TiOC?

WizSense cameras detect threats and alert you silently — they record and notify. TiOC cameras do the same, then actively respond with red/blue strobe lights and a 110dB siren. Use WizSense for broader coverage positions, TiOC at primary entry points where deterrence matters most. Explore our Dahua TiOC 3.0 range for active deterrence options.

AI SSA (Scene Self-adaptation) automatically adjusts camera image settings when it detects rain, fog, backlight, flicker, or low-light conditions — ensuring consistently clear, usable footage without any manual reconfiguration.

Quick Pick lets you search recorded footage by clothing colour, vehicle colour, or vehicle type — surfacing matching clips from hours of multi-channel recordings in seconds. Available when WizSense cameras are paired with a compatible Dahua WizSense AI NVR.

Do WizSense cameras have a built-in microphone?

Yes — most Dahua WizSense 3-series cameras include a built-in microphone for audio recording. Two-way audio via the DMSS app is supported on models with audio output capability.
