Product Core Highlights

• 12MP High Resolution: Provides detailed image capture for high-resolution security and embedded camera modules.
• 114.4° Ultra-Wide FOV: Covers a broad scene with a 5mm focal length, helping reduce blind areas in close-range monitoring.
• F2.0 Aperture: Provides a relatively bright optical system for indoor and variable-light imaging environments.
• IR Corrected Design: Helps maintain focus consistency between visible and near-infrared wavelengths for day-and-night camera systems.
• Compact M12 Mount: Supports integration into small camera housings and space-constrained imaging devices.

Why Choose This 5mm M12 Wide Angle Lens?

The combination of a 5mm focal length, 114.4° diagonal FOV, and 12MP resolution provides a useful balance between wide scene coverage and detailed image capture. Compared with extremely short focal length lenses, the 5mm design offers a somewhat more controlled viewing angle while still covering a large area.

The lens is built around a 1/1.7″ image format and uses an M12 mount, making it suitable for compact high-resolution camera modules. Its 6.05mm BFL also supports optical integration where limited installation space is available.

Unlike a basic wide-angle lens, this model is specifically specified as IR Corrected, making it a strong option for camera systems that operate across visible and near-infrared wavelengths.

For applications requiring a more controlled optical geometry, TOWIN also offers low distortion lens solutions.

12MP Resolution for Detailed Wide-Area Imaging

A 12MP resolution allows this lens to capture significantly more image detail than standard 2MP or 3MP compact camera configurations.

When combined with an 87° horizontal FOV, the lens can cover a relatively large area while retaining sufficient pixel information for monitoring and image analysis. This makes it suitable for applications where both scene coverage and image detail are important.

Typical use cases include:

• Smart security cameras
• Indoor monitoring systems
• Wide-area CCTV
• Commercial surveillance
• Embedded vision devices
• High-resolution compact cameras
• Intelligent monitoring equipment

The lens is not intended primarily for precision measurement because its specified -43% distortion indicates a strong wide-angle optical design. Instead, it prioritizes broad scene coverage and compact integration.

Ultra-Wide Field of View with 5mm Focal Length

The 114.4° diagonal FOV and 87° horizontal FOV allow the lens to capture a wide scene without requiring an extremely short focal length.

This configuration can be useful when a camera needs to observe a large area from a relatively short installation distance. It can help reduce blind zones in indoor monitoring, entrances, retail environments, and compact security systems.

For engineers selecting focal length based on sensor size, working distance, and required coverage, TOWIN provides a lens selection guide and FOV calculator.

IR Corrected for Day-and-Night Imaging

The IR Corrected specification is an important feature for security cameras that operate in both daytime and nighttime conditions.

In conventional optical systems, visible light and near-infrared wavelengths can focus at different positions, potentially causing image sharpness to change when an IR illumination system is activated. An IR corrected lens is designed to reduce this focus shift and maintain more consistent imaging performance across the relevant wavelength range.

This makes the lens particularly suitable for:

• Day-and-night CCTV cameras
• IR-illuminated security cameras
• Smart surveillance systems
• Indoor and outdoor monitoring
• Security camera modules requiring near-infrared imaging

Compact M12 Optical Integration

The M12 mount and 6.05mm BFL make this lens suitable for compact camera architectures where optical space is limited.

M12 lenses are commonly used in embedded camera modules because their small mechanical footprint allows optical systems to be integrated into compact housings without requiring the larger mechanical interfaces associated with C-Mount or CS-Mount systems.

This lens therefore works for compact high‑resolution camera designs combining wide‑angle coverage, 12MP imaging, and IR performance in a single optical assembly.

M12 Wide Angle Lens Applications

Core Application Scenes

Designed for wide-angle day-and-night monitoring applications, this 5mm M12 lens is suitable for systems that require high-resolution imaging, broad coverage, and stable visible/NIR focusing.

1. Smart Security & CCTV Monitoring

The 87° horizontal FOV provides broad scene coverage for indoor security, commercial monitoring, entrances, corridors, and other areas where a compact camera must observe a relatively large field.

The 12MP resolution provides additional image detail for monitoring systems that require more information than conventional low-resolution CCTV cameras.

2. Day-and-Night Surveillance

The IR corrected design makes this lens particularly suitable for security cameras using infrared illumination. It can help maintain consistent focus when the camera switches between visible-light and near-infrared operating conditions.

3. Retail & Commercial Monitoring

The combination of wide FOV and 12MP resolution can support retail surveillance systems where operators need to monitor broad areas while retaining detailed image information for later inspection.

4. Embedded Vision Systems

The compact M12 mount allows integration into embedded camera modules used in smart devices, monitoring equipment, and other space-constrained imaging platforms.

5. Wide-Area Indoor Imaging

The 5mm focal length offers broad coverage while avoiding the extremely short focal lengths typically used for the most aggressive ultra-wide designs. This makes it ideal for indoor environments that need to balance wide coverage and recognizable image detail.

Compatible Devices

This lens can be considered for integration with:

• 1/1.7″ 12MP camera modules
• M12 high-resolution camera modules
• Smart security cameras
• IR surveillance cameras
• Day-and-night CCTV cameras
• Wide-angle CCTV systems
• Indoor monitoring cameras
• Retail security cameras
• Embedded vision devices
• Compact intelligent camera systems

Wide Angle Coverage vs. Low Distortion Imaging

The specified -43% distortion indicates that this lens is optimized for a wide-angle field of view rather than precision geometric reproduction.

This distinction is important when selecting an industrial or security lens. Wide-angle designs intentionally accept stronger image deformation to capture a larger scene within a limited sensor area. This can be advantageous for monitoring applications where coverage is more important than maintaining perfectly straight lines.

For dimensional measurement, metrology, precise object positioning, or inspection applications, a dedicated low distortion lens would generally be more appropriate.
