Hanwha Techwin SLA-2M2400Q: 2.40mm Fixed Lens for M12 Mount

Meet the Hanwha Techwin SLA-2M2400Q, a compact, high-performance fixed lens designed specifically for M12-mount surveillance cameras. This family-friendly lens delivers dependable 2MP image quality across a range of focal lengths, enabling security teams to tailor field of view to any environment—from tight hallways to broad outdoor entrances. Built to integrate seamlessly with Hanwha Techwin cameras and other M12 platforms, the SLA-2M2400Q combines precise optics, reliable low-light performance, and a durable form factor in a compact package. Whether you are upgrading older cameras or outfitting a new system, this lens provides a flexible, value-driven solution that helps you capture detailed, actionable footage when it matters most.

• Selectable focal lengths for flexible surveillance: Choose among 2.4, 2.8, 3.6, and 6.0 mm fixed lenses to configure the perfect field of view for each camera location. Shorter focal lengths deliver wide coverage ideal for corridors and entrances, while longer focal lengths bring distant details into sharper focus for facial recognition and license plate capture. The SLA-2M2400Q family enables you to optimize coverage without swapping lenses or reconfiguring cameras, supporting scalable deployments and future-proofing your security setup.
• 2MP image quality with low-light capability: Engineered for clear surveillance imagery, the SLA-2M2400Q supports 2MP resolution with impressive low-light performance. The lens is rated at 0.055 lux at F2.0, helping you maintain better visibility in dim environments. This low-light performance translates into cleaner color and monochrome footage, reduced motion blur, and enhanced detail in critical moments—so suspects and details are more likely to be captured accurately even after dusk.
• Compact, versatile M12-mount design: With a compact 1.4" length and a 1.4" diameter, this lens is ideal for tight enclosures, dome cameras, and smaller form-factor systems. The M12 mount is a widely adopted standard in security cameras, enabling quick integration and broad compatibility across many camera models. The slim profile minimizes protrusion, helping to preserve aesthetic lines while maintaining reliable alignment and optical performance.
• Color or B/W options for adaptable imaging: The SLA-2M2400Q family offers 2MP lenses that are available in color and black-and-white variants. Color options excel in well-lit conditions where color details aid identification, while B/W variants can improve contrast, reduce noise, and deliver crisper silhouettes in challenging lighting. This versatility supports a wide range of environments—from retail spaces to industrial facilities—allowing you to select the mode that best suits your surveillance goals.
• Reliability, compatibility, and ease of integration: Designed to deliver consistent performance in security deployments, the SLA-2M2400Q offers reliable optics with stable focus and minimal distortion across the frame when paired with compatible cameras. Its M12-mount interface ensures straightforward integration with Hanwha Techwin systems and other M12-enabled cameras, reducing installation time and warranty concerns while delivering dependable year-round operation in both indoor and outdoor environments with proper enclosure and protection.

How to install Hanwha Techwin SLA-2M2400Q

• Power down the camera system before handling any lens components to prevent electrical or mechanical damage.
• Identify the correct mounting interface on your camera. The SLA-2M2400Q uses the standard M12 mount, which is common in many compact surveillance cameras.
• Remove the existing lens (if applicable) by carefully unscrewing or detaching it from the M12 housing, taking care not to damage the camera sensor or connector.
• Clean the M12 thread area and the exterior of the lens mount to remove dust, debris, or fingerprints that could affect image quality or sealing.
• Choose the focal length you need for your installation (2.4, 2.8, 3.6, or 6.0 mm). Attach the SLA-2M2400Q by aligning the threads with the camera mount and rotating gently until snug. Do not over-tighten, as this can damage the lens or the mount.
• Ensure proper alignment so that the optical axis is centered with the camera sensor. Confirm that the lens seats fully and that there is no tilt or misalignment that could cause distortion at the edges of the frame.
• Power on the camera and verify the field of view. If the scene is too wide or too narrow, swap in another focal length option from the SLA-2M2400Q family to reconfigure coverage without removing the camera or the mount.
• If applicable, adjust any camera-side settings (digital zoom, crop, or ROI) to complement the fixed focal length for optimal clarity and frame utilization. Re-check focus and sharpness on the live feed and confirm there are no vignetting or chromatic aberrations in the edges of the image.
• Test performance under varying lighting conditions to ensure the chosen focal length maintains the desired balance of exposure, depth of field, and subject visibility across the scene.
