8MP 3X 3.6-10mm zoom security camera lens/ITS lens

This lens employs a standard CS mechanical mount and offers continuously variable focal length adjustment from 3.6 mm to 10 mm. It delivers a balanced optical performance—supporting both wide-angle, large-field-of-view surveillance and mid-range target identification with enhanced detail resolution. The iris is fully mechanically actuated, eliminating the need for DC drive circuitry; this contributes to a compact, rugged, and inherently reliable design. The lens is optimized for use in environments with stable illumination conditions and is particularly well suited for machine vision systems, embedded image acquisition devices, and indoor/outdoor security cameras.

Key Technical Specifications and Features：

1. Continuous manual zoom range (3.6–10 mm): Enables flexible field-of-view adaptation—from expansive panoramic coverage at 3.6 mm to precise mid-range target identification at 10 mm. A single lens accommodates diverse monitoring distances, significantly reducing on-site installation time, configuration effort, and operational tuning complexity.

2. Purely mechanical iris mechanism: Requires no electronic drive components or camera-side DC iris control circuitry. Under consistent lighting conditions, it ensures highly repeatable and stable exposure control, resulting in exceptional long-term reliability and minimal maintenance requirements—ideal for industrial machine vision and embedded AI vision applications.

3. Full-spectrum parfocal optical design (visible + near-infrared): Specifically corrected for infrared wavelengths (850 nm and 940 nm), maintaining focus consistency across visible and NIR bands. This eliminates refocusing during day/night transitions and ensures uninterrupted 24/7 imaging performance under IR-illuminated conditions.

4. Triple independent mechanical locking system: Dedicated locking mechanisms for the zoom, focus, and iris adjustment rings prevent parameter drift induced by mechanical vibration, thermal cycling, or other environmental stressors—thereby enhancing long-term calibration stability and operational robustness.

5. Native CS-mount compatibility: Directly interoperable with industry-standard CS-mount security box cameras and industrial area-scan/line-scan cameras. For C-mount cameras, seamless integration is achieved using a commercially available CS-to-C adapter spacer (1.27 mm thickness).

Typical Application Domains：

Security Surveillance: Deployed in indoor warehouses, retail premises, underground parking facilities, building corridors, and fixed-position outdoor sites. Supports simultaneous wide-area situational awareness and high-fidelity detail capture within critical zones—without requiring lens swapping or reconfiguration.

Machine Vision: Widely adopted in automated optical inspection (AOI), workstation-based object recognition, embedded AI inference cameras, and similar industrial applications. Particularly advantageous in production-line environments and equipment-integrated setups characterized by controlled lighting and thermally stable operating conditions.

Intelligent Transportation Systems (ITS): Applied in license plate recognition (LPR) and facial recognition systems at toll plazas, access control gates, and vehicle entry/exit points—leveraging consistent focus and exposure stability across varying ambient light levels.

Specialized All-in-One Vision Systems: Integrated into custom-built vision platforms where size minimization, ultra-low power consumption, or automated control are not primary design constraints—e.g., educational video recording terminals, cabinet-mounted camera modules, and edge-computing enclosures with integrated optics.
