Designed to fit standard M12 mounting systems, this 4.6 mm focal length lens (with an aperture of f/1.6) is ideal for installing into a wide range of security cameras where image clarity and reliability matter most. Whether you are outfitting a small storefront, a parking area, or a multi-camera campus installation, this lens delivers consistent, dependable results with minimal distortion and excellent color fidelity, making it a trusted choice for professional security deployments.

• Premium 5MP-compatible fixed lens: Built to align with 5MP surveillance cameras, the SLA-5M4600Q provides crisp, detailed imagery that helps security teams identify faces, license plates, and other important details with confidence. This lens is optimized to deliver clear edge definition across the frame, reducing blur and enhancing scene accuracy in fast-moving or dynamic environments.
• Selectable focal lengths for flexible coverage: While the primary offering is a precise 4.6 mm focal length, Hanwha Techwin also provides fixed lenses in 3.7 mm and 7.0 mm options. This allows you to tailor the field of view to the specific surveillance scenario—opt for a wider view to cover larger areas or select a longer focal length to focus on distant objects. The SLA-5M4600Q family covers a range of coverage needs without sacrificing image quality.
• Outstanding low-light performance: Achieve usable imagery in dim lighting thanks to a bright aperture of f/1.6 and a sensitivity specification that supports 0.16 lux at F1.6. This makes the lens well-suited for nighttime monitoring, dim hallways, entryways, and other challenging lighting conditions where other lenses may struggle to capture essential details.
• Compact, robust build for easy integration: With a compact form factor—approximately 1.4 inches in length and 1.4 inches in diameter—the SLA-5M4600Q blends seamlessly into tight camera housings and discreet installations. The lens is designed for enduring operation in security environments, offering stable performance in varied temperatures and setups when paired with appropriate housing and mounting hardware.
• Simple compatibility with M12-mount cameras: This lens is purpose-built for M12-mount surveillance cameras, enabling quick upgrades or replacements without complex adapters or bespoke components. It supports straightforward installation on a broad class of IP and analog cameras that use the popular M12 lens interface, helping installers reduce project timelines and ensure consistent imaging across a site.

how to install Hanwha Techwin SLA-5M4600Q

• Power down the camera and verify the replacement lens is compatible with the camera’s M12 mount and overall electrical and optical specifications.
• Remove the existing M12 lens from the camera’s lens holder, taking care not to damage adjacent components or seals if the camera is housed in a weatherproof enclosure.
• Carefully align the SLA-5M4600Q with the camera’s M12 thread and begin threading by hand to avoid cross-threading. Tighten until the lens is seated firmly but do not overtighten, which could damage the thread or housing.
• Once secured, verify that the lens is correctly oriented to provide the intended field of view. Since this is a fixed focal length lens, any focus or framing adjustments should be performed through the camera’s own configuration settings or by selecting a different focal-length lens in the SLA-5M4600Q family if your application requires a different view.
• Power the camera back on and perform a test capture. Check for image sharpness, exposure, and color balance across the scene. If needed, adjust camera exposure, white balance, and scene parameters to optimize the overall image quality for the surveillance environment.
• Mount the camera in its operational position and confirm stability. Ensure weatherproof seals and connections remain intact if the installation is exposed to outdoor conditions.
• Document the installation details, including focal length choice, mounting orientation, and any camera-side adjustments, to simplify maintenance and future upgrades.

Frequently asked questions

• Q: What focal lengths are available for the SLA-5M4600Q family?
• A: The primary lens is 4.6 mm, with selectable fixed-lens options in 3.7 mm and 7.0 mm to cover a range of field-of-view requirements. This provides installers with the flexibility to tailor coverage for different camera placements and scene sizes.
• Q: Is the lens suitable for low-light environments?
• A: Yes. With a fast aperture of F/1.6 and a 0.16 lux performance at F1.6 specification for the 5MP configuration, the lens is capable of delivering usable imagery in low-light conditions, particularly when paired with cameras that optimize sensitivity and exposure settings.
• Q: What type of camera mounts does it fit?
• A: It is designed for M12-mount cameras, a common standard in compact surveillance devices. This makes it compatible with many IP and analog security cameras that support M12 lenses.
• Q: Can I adjust focus with this lens?
• A: This lens is a fixed focal length lens. Focus adjustments, if needed, are typically managed through the camera’s focus controls or by selecting a different focal-length lens in the same product family during installation.
• Q: What resolutions does this lens support?
• A: The SLA-5M4600Q is designed for 5MP cameras, providing high-detail imaging suitable for security applications that require precise identification and scene detail. For color vs. BW, it supports the corresponding modes offered by the camera system and the specific SLA-5M4600Q variant being used.
• Q: How do I optimize the field of view for my installation?
• A: Choose the focal length option that best fits your scene. For a broad entryway, a shorter focal length (3.7 mm or 4.6 mm) often yields a wider view, while a longer focal length (7.0 mm) focuses more on distant objects. Install the lens in the camera, then fine-tune framing and exposure in the camera’s settings to achieve the desired balance between coverage and detail.
