Whether you’re securing a retail storefront, monitoring a lobby, or supervising outdoor perimeters, this lens is built to help you capture meaningful details with confidence.

At the core of its performance is an optical design that prioritizes high-resolution image quality. The 2.7-13mm focal length range gives you flexible framing—from broad, scene-setting views to tight, targeted captures—without swapping lenses. The lens is tuned to minimize distortion and maintain edge-to-edge sharpness, so scenes remain consistent as you adjust the zoom. For security operators and installers, this means fewer compromises when configuring cameras for varying distances, lighting, and field-of-view requirements. The result is crisper video, improved object recognition, and more reliable evidence for investigations or remote monitoring. Additionally, Bosch’s engineering ensures compatibility with a wide array of CS-mount cameras, enabling easier integration into existing security infrastructures and future-proofing your deployment as needs evolve.

In real-world deployments, a varifocal CS-mount lens helps you tailor the camera’s view to the space you’re protecting. The 2.7-13mm range covers everything from wide entries and aisles to mid-range corridors and parking areas. Paired with modern processing, the lens delivers superior color rendition, accurate detail rendering, and consistent performance across the zoom range. The design is optimized for surveillance-grade reliability, delivering dependable operation in busy environments where lighting can shift throughout the day. With the f/1.4 aperture, you’ll benefit from enhanced low-light performance, enabling clearer images during dawn, dusk, and nighttime surveillance when detail matters most. This combination of flexibility, clarity, and light-gathering capability makes the Bosch lens a practical choice for crime prevention, incident analysis, and live monitoring across a diverse set of applications.

Beyond optics, the lens features a compact, robust form factor that fits neatly into standard CS-mount housings. Its physical profile is conducive to discrete installations and easy maintenance, helping technicians complete deployments quickly without sacrificing image quality. The result is a dependable lens that supports scalable security strategies—one that fits neatly into a variety of camera platforms and installation scenarios while maintaining consistent optical performance across the focal range.
