3MP 1/2.7" CS-Mount HD IR Security Monitoring Industrial CCTV Varifocal Lens YT-4866

YT-4866:3MP variable focus CCTV lens with infrared night vision support

IR-Compatible Design

Specially optimized for infrared illumination, the lens features an advanced optical design and coating treatment that effectively eliminates focus shift between visible and IR light sources—ensuring consistent image sharpness both during the day and at night under IR lighting.

3MP High Resolution

Delivers clear, detailed image output with high contrast and accurate edge definition, making it ideal for advanced HD applications such as intelligent surveillance, machine vision, and precision monitoring where image clarity is critical.

2.8–12mm Manual Zoom with Lock

Offers a versatile 2.8–12mm focal range that allows seamless transitions from wide-angle to mid-telephoto views, while the integrated locking mechanism ensures precise focus and zoom settings remain stable even under vibration or long-term use.

Auto-DC Iris Control

Equipped with an Auto-DC iris, the lens automatically adjusts aperture size in response to varying lighting conditions, maintaining optimal exposure and consistent contrast—ensuring clear images from bright daylight to low-light environments without manual intervention.

Wide Field of View: 112° to 34°

Engineered to deliver flexible imaging performance, the lens supports both wide-area surveillance with a 112° field of view and focused detection at narrower angles down to 34°, when used with 1/2.7" image sensors—making it ideal for scenarios that require both broad monitoring and detailed target observation.

Rugged Aluminum Housing

Built with a rugged anodized aluminum housing, the lens offers excellent resistance to wear, corrosion, and environmental stress. Its internal 9-element all-glass optical structure is precisely engineered to enhance image clarity, reduce aberrations, and ensure long-term stability in demanding industrial or outdoor conditions.
