Extra Info
All-in-One Surveillance – Panoramic + PTZ in One Device
This innovative model combines four panoramic lenses with a powerful PTZ (Pan-Tilt-Zoom) camera, offering a complete surveillance solution in one unit. The panoramic module delivers a seamless 180° horizontal field of view, eliminating blind spots and ensuring continuous situational awareness. Meanwhile, the PTZ module features 37x optical zoom and full rotation capabilities for dynamic, real-time tracking. Together, they provide comprehensive wide-area coverage and focused zoom for detailed event monitoring — perfect for perimeter security, campuses, public plazas, or industrial zones.
Smart Tracking in Action – Automated Threat Response
When a person or vehicle crosses a virtual tripwire or enters a defined zone, the system automatically instructs the PTZ camera to zoom in, follow, and record the target. This smart integration between fixed and movable lenses enables hands-free active tracking, reducing the need for constant manual control. For high-risk or live incidents, operators can also manually trigger PTZ tracking via control software or NVR, enhancing responsiveness in security-critical environments.
Advanced Low-Light Imaging – Crisp Night Detail Without IR
Dahua’s Starlight+ technology equips both the panoramic and PTZ modules with superior low-light performance. Even before infrared (IR) illumination activates, the camera captures high-clarity, color-rich footage in near-dark conditions. This allows earlier identification of subjects and better visual context during dusk, dawn, or in poorly lit areas — ensuring effective monitoring around the clock.
Deep Learning IVS – Accurate Detection with Fewer False Alarms
With built-in deep-learning-based IVS (Intelligent Video System), the camera uses Convolutional Neural Network (CNN) algorithms to accurately detect and classify human and vehicle activity, significantly minimizing false alarms caused by irrelevant movement such as wind, shadows, or animals. This makes the system ideal for use in high-traffic, outdoor environments, where reliable, targeted alerts are essential.
Extreme Range IR Night Vision – Up to 220m PTZ Visibility
The PTZ camera features Smart IR night vision with an impressive reach of up to 220 meters. This allows for detailed black-and-white imagery even in complete darkness over large spaces, such as logistics yards, agricultural fields, or secured industrial compounds — providing uninterrupted visibility when and where it matters most.
Privacy and Custom Zones – Secure and Efficient Monitoring
Support for up to 24 privacy mask zones on the PTZ module and 4 zones on the panoramic view allows operators to block out sensitive areas from surveillance footage — such as neighboring properties or private offices. Additionally, Regions of Interest (RoI) can be defined to prioritize recording quality in key areas while using lower bandwidth and storage for less critical zones, optimizing overall system performance.
Flexible Install Options – Tailored for Any Site Layout
The camera supports a variety of installation types, including wall, pole, or pendant (hanging) mounts, using compatible Dahua brackets. Its dual network compatibility enables connection via fiber optic or Ethernet (RJ45) interfaces, offering flexibility for long-distance transmission or existing infrastructure integration.
