Description
Uniview IPC9312LFW-AF28-2X4 2×2MP Dual-Lens Lighthunter PTZ Network Camera
This dual-lens PTZ camera combines panoramic overview with zoom-detail in one integrated casing. With one fixed 2.8mm lens for broad situational awareness, plus a motorized PTZ lens (2.8-12mm, 4× optical zoom) for close inspection, it delivers the “see everything and zoom in where it matters” capability. Lighthunter technology ensures exceptionally low-illumination image clarity; IR + warm light illumination options keep the scene colorized or visible at night. Add in strong smart detection, two-way audio, and flexible mounting, and you’ve got a powerful solution for demanding security environments.
Key Features

Lighthunter low-light tech: very low lux requirement, color imaging even in dim conditions
-
Wide Dynamic Range (120 dB) to handle strong contrast lighting scenes
-
Built-in dual microphones + speaker for two-way audio / announcements
-
IR + warm light illumination for flexible night performance
-
Smart intrusion detection: cross-line, enter/leave area, etc., with false alarm filtering
-
ONVIF compliance and common network protocols for integration
-
Power options: 12 VDC or PoE+ (IEEE 802.3at)

Use-case & Installer Notes
-
Ideal for sites where both wide area oversight and detailed inspection are necessary (e.g. building entrances, parking lots adjacent to perimeter walls, campuses). The fixed lens watches the full scene; when detection or alert triggers, PTZ zooms in.
-
Warm light + IR combo allows colored view when human-relevant color matters (faces, clothing) and IR when stealth or maximum range needed.
-
For best results, enable smart detection + false alarm filtering to reduce nuisance alerts from minor motion. Use the master-slave linkage between fixed and PTZ channel to have PTZ respond to events detected on fixed lens.
-
Proper mounting (height, angle) influences performance: avoid glare/bright light directly in view; ensure the PTZ has enough clearance to pan/tilt without obstructions.
