Hanwha Techwin SLA-5M3700Q – 3.70 mm F1.6 Fixed Lens for M12 Mount

Engineered for reliable, high-detail surveillance, the SLA-5M3700Q is a compact fixed lens designed for M12-mount cameras. This 3.70 mm focal length lens delivers sharp 5MP imaging with excellent color fidelity and low-light performance. Available in multiple fixed focal options—3.7 mm, 4.6 mm, and 7.0 mm—these lenses let integrators tailor field of view to each camera position. With a compact 1.4" length and diameter, the SLA-5M3700Q fits in tight enclosures and is ideal for retail, office, and outdoor security deployments where space is at a premium. Whether you’re upgrading an existing 5MP IP camera or equipping a compact surveillance setup, this lens delivers the clarity and reliability essential for identification, monitoring, and evidence gathering.

• 3.7mm fixed focal length with F/1.6 aperture provides bright, high-contrast 5MP imagery in both color and monochrome modes. The fast aperture helps capture clearer details in low-light environments, making it a solid choice for entrances, aisles, and parking areas where lighting can fluctuate.
• Easy integration with M12-mount cameras—the SLA-5M3700Q is designed to drop into compact camera housings and align with standard M12 interfaces, minimizing installation time while preserving image quality and field of view.
• Selectable lens options for flexible deployments—in addition to the 3.7 mm variant, this family includes fixed lenses at 4.6 mm and 7.0 mm. This allows you to optimize coverage from wide-angle surveillance to more focused, distant viewing without changing the camera body.
• Outstanding low-light performance—rated at 0.16 lux @ F1.6, the SLA-5M3700Q helps capture usable color and grayscale imagery in dim conditions, reducing the need for additional lighting and helping to preserve image integrity at night or in shaded areas.
• Compact, robust design for tight spaces—measuring about 1.4" in both length and diameter, this lens fits behind small enclosures, dome housings, or compact cameras while delivering consistent 5MP quality and reliable operation in demanding environments.

How to install Hanwha Techwin SLA-5M3700Q

• Power down your surveillance system and disconnect power before handling the lens to avoid damage.
