1/2" 30-120mm Manual Iris Zoom Lens CS-Mount 5MP for Security Surveillance Camera

1/2-inch industrial lens, 30–120 mm manual zoom (4× optical), optimized for high-precision long-distance imaging. Supports 5 MP (2592 × 1944) resolution, CS-mount interface, manual iris, and manual focus. Covers mid-range surveillance and long-range identification in one field of view. Optical design suppresses chromatic aberration, distortion, and vignetting—delivering sharp, consistent image quality edge-to-edge. Precisely matched to 1/2-inch sensors: no vignetting, full pixel utilization. All-metal housing ensures reliability in harsh environments—outdoor cabinets, towers, industrial sites—supporting 7×24 operation.

Key Parameters：

• Sensor: 1/2″ (5 MP CMOS)
• Zoom range: 30–120 mm (4× optical)
• Resolution: ≥5 MP (2592 × 1944)
• Mount: CS
• Iris: Manual
• Focus: Manual
• Working distance: Medium-to-long range; reliable recognition ≥100 m (under good light and contrast)

Product Advantages：

1. 4× zoom (30–120 mm): Switch between wide-area view and detail without changing lenses—ideal for perimeter security and elevated monitoring.
2. Manual iris: Adjust exposure on the fly—close in bright light to avoid overexposure; open in low light to boost signal-to-noise ratio.
3. CS-mount: Fits most industrial and security cameras; stable mounting reduces focus shift from vibration or temperature changes.
4. 5 MP across zoom range: Consistent sharpness and MTF—meets demands of license plate recognition, defect detection, and AI vision tasks.
5. Exact sensor match: Eliminates vignetting and edge dimming—uses full sensor area efficiently.
6. Metal build: Resists heat, corrosion, and impact—designed for outdoor, industrial, and unmanned deployments.

Typical Applications：

• Security: Perimeter monitoring, border/river/dam surveillance, critical infrastructure observation
• Transportation: Highway license plate recognition, railway line monitoring, bridge/tunnel entry surveillance
• Industry: Remote inspection of turbines, pipelines, reactors; high-temp/pressure/hazardous environment imaging
• Special use: Wildlife tracking, archaeological site documentation, emergency aerial perspective
• Vision systems: Core lens for 5 MP CS-mount cameras—supports AI training, real-time inference, and precision measurement
