Uniview 2*2MP Lighthunter Dual-lens Network PTZ camera (IPC9312LFW-AF28-2X4)

The Uniview IPC9312LFW-AF28-2X4 is a highly advanced and versatile 2MP Dual-Lens Network PTZ (Pan/Tilt/Zoom) Camera designed for comprehensive surveillance, offering both a wide overview and detailed zoom capabilities within a single IP address. This camera is part of Uniview’s LightHunter series, known for exceptional low-light performance.

Key Features:

Dual-Lens System (2*2MP):
- Fixed Panorama Lens (Top): A fixed 2.8mm lens provides a wide, static overview of the scene (approx. 102.4° horizontal field of view). This lens maintains constant surveillance of the overall area.
- PTZ Detail Lens (Bottom): A 2.8~12mm motorized varifocal lens with 4X optical zoom allows for remote pan (0° ~ 345°) and tilt (-10° ~ 100°) adjustments to focus on specific details.
- Single IP Address: Both cameras operate under one IP address, simplifying network configuration and management.
- Master-Slave Linkage: The PTZ lens can be intelligently linked to the fixed lens. When the fixed lens detects an intelligent event (like intrusion or line crossing), it can automatically cue the PTZ lens to zoom in and track the subject.
2MP High-Quality Imaging: Equipped with a 1/2.8″ CMOS sensor, both lenses deliver crisp 2-megapixel (1920×1080) resolution video at up to 25/30 frames per second.
LightHunter Technology: This is Uniview’s proprietary technology designed for ultra-low light performance. It combines a large F1.6 aperture lens, a BSI (Backside-Illuminated) sensor, and advanced U-ISP algorithms to produce vivid color, appropriate brightness, and extremely clear images even in minimal illumination (as low as 0.002 lux in color). This allows for color footage where traditional cameras would switch to black and white.
Dual Illumination (IR & White Light):
- IR Illumination: Provides traditional black-and-white night vision for the PTZ lens up to 50 meters (164 feet). The fixed lens also has IR illumination up to 10m.
- Warm Light Illumination: The PTZ lens includes a white LED illuminator for short-range (up to 10 meters) full-color night vision, ideal for scenarios where color information is critical even in darkness. This also enables active deterrence.
Active Deterrence: Features built-in 2 microphones and a high-power speaker for two-way audio communication and audible alarms. When an intelligent event is detected, the camera can trigger pre-recorded audio warnings or a live voice message, and flash its white light to deter intruders.
Intelligent Functions (Smart Intrusion Prevention – SIP):
- False Alarm Filtering: Based on deep learning AI, it accurately distinguishes humans and vehicles from other moving objects (like animals, leaves, rain, or light changes), significantly reducing false alarms.
- Detection Types: Supports Cross Line, Intrusion, Enter Area, and Leave Area detection.
- Auto Tracking: The PTZ lens can automatically track detected human or vehicle targets.
Efficient Video Compression: Supports Ultra 265, H.265, H.264, and MJPEG to optimize bandwidth and storage usage while maintaining high image quality.
Wide Dynamic Range (WDR): Up to 120dB Optical WDR ensures clear images in scenes with strong contrast (e.g., bright highlights and dark shadows).
Flexible Storage: Features a Micro SD card slot supporting up to 256GB for edge storage, providing backup in case of network interruption (ANR – Automatic Network Replenishment).
Network & Power: Supports both DC12V and PoE+ (IEEE 802.3at) for power, offering flexible installation options.
Robust & Weatherproof Design: With an IP66 rating, it is highly resistant to dust and water, suitable for demanding outdoor environments (operating temperature -20℃ to 60℃). It also has 2KV surge protection.
Easy Integration: Compatible with mainstream ONVIF (Profile S, G, T) and RTSP protocols.

The Uniview IPC9312LFW-AF28-2X4 is an excellent solution for complex surveillance needs, providing both a continuous wide overview and the ability to zoom in on specific events with smart tracking and active deterrence capabilities, all while performing exceptionally well in low-light conditions.
