Extra Info
Smart IR with 60m Range
This model adapts IR brightness based on object distance, helping you avoid washed-out faces or plates even when subjects are very close to the lens. It allows solid visibility in full darkness up to 60 meters.
Flexible Zoom Options
You can choose between two lens models: the motorized ZS for remote zoom/focus (ideal for changing views over time) or the VFS model for simple manual setups where physical access isn’t a concern.
WDR for Challenging Light
True 120dB WDR helps keep images balanced when there are shadows and bright backgrounds in the same frame, such as storefronts or indoor areas near windows.
Smart H.265+ Encoding
Reduces storage requirements by intelligently adjusting how footage is recorded based on motion, focus areas, and background activity—ideal for maximizing microSD or NVR capacity.
Durable for Harsh Conditions
IP67-rated and with surge protection, this camera can be confidently installed outdoors in extreme weather, industrial zones, or dusty areas.
Tamper Alerts
In addition to IVS rules, the camera also detects if someone is trying to obscure, move, or physically tamper with the view and sends alerts accordingly.
AcuPick – Smart Search (With AI NVR)
While the camera itself doesn’t process AcuPick, when used with a compatible Dahua AI NVR, you can leverage this powerful search tool. AcuPick filters footage using AI-classified human or vehicle presence, letting you jump straight to relevant events with just a few clicks.
Benefits with AI NVR Integration:
- Search by person or vehicle in seconds
- Filter by color or shape traits (e.g. red shirt, white car)
- Skip irrelevant footage and reduce review time
- Ideal for retail, driveways, public areas, or gated entries
