Extra Info
Eco-Savvy Compression with Smart H.265+
This camera uses Smart H.265+, Dahua’s intelligent video compression technology that adapts to motion and scene complexity. It significantly reduces file sizes, bandwidth use, and storage needs by up to 70%, all while maintaining image clarity. This is ideal for sites with multiple cameras, limited network capacity, or long-term footage retention without the need for massive storage upgrades.
Face Detection & Scene Analytics
Beyond standard motion detection, this model includes AI-based face detection, which automatically captures and logs facial snapshots for use with compatible NVRs. It also features smart scene analysis, such as identifying abandoned or missing objects and detecting movement in restricted areas. These analytics help operators respond faster and make footage review more efficient—great for lobbies, entrances, or high-security zones.
Long-Distance ePoE Transmission
Dahua’s Enhanced Power over Ethernet (ePoE) technology allows simultaneous video and power transmission over distances of up to 800 meters on Cat5 or coaxial cable (at 10 Mbps). This simplifies installations for large-scale deployments like school campuses, perimeter fencing, or multi-building facilities by reducing the need for extra power infrastructure or network relays.
Weatherproof and Rugged Design
Built to withstand harsh outdoor conditions, the camera carries an IP67 rating, making it resistant to rain, dust, and water jets. It also operates in a wide temperature range of –30°C to +60°C, allowing dependable performance year-round in hot, cold, wet, or dusty environments. This makes it perfect for parking lots, gates, industrial zones, and coastal areas.
Starlight CMOS Sensor for Low-Light Color
The integrated Starlight CMOS sensor is engineered for superior low-light performance, enabling the camera to capture full-color images even in very dim conditions—well before switching to IR. This helps preserve important visual details like clothing color, vehicle paint, or skin tone, improving evidence quality during dawn, dusk, or under minimal ambient lighting.
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
Q&A
Q: Can I change the lens after purchase?
No—the lens is fixed (2.8mm or optional 3.6mm), so make sure to choose the right field of view before ordering.
Q: What is the advantage of Starlight CMOS?
It provides clearer images in low-light without needing to switch to black-and-white mode immediately, extending color capture in twilight conditions.
Q: How is this different from regular PoE?
ePoE allows much longer cable runs—up to 800m—compared to standard PoE's typical 100m limit.
Q: Does this camera support face detection?
Yes—it can detect and capture faces for security analysis and upload to servers or NVRs.
Q: Can I record without a DVR or NVR?
Yes—the camera includes a microSD slot that supports up to 128GB for edge recording.
Q: Does this have IR overexposure prevention?
Yes—Smart IR adjusts the IR LED brightness to avoid washing out nearby objects.
Q: Can this be used in humid outdoor areas?
Yes—it's IP67-rated and works in up to 95% humidity and heavy rain.
Q: Is this camera suitable for vandal-prone areas?
No—it is not IK10-rated. If vandal resistance is a priority, another model with IK10 would be recommended.
