CHANCCTV details varifocal lens guide for security monitoring systems

Fuzhou ChuangAn Optics Co., Ltd. is promoting varifocal lens selection guidance for security monitoring projects, with custom support, sample testing and published optical specifications aimed at helping integrators match the right lens to the right camera. The company says the approach is designed to reduce integration risk and speed deployment for CCTV and machine vision applications.

Why it matters: - Security monitoring projects often change in distance, target size and lighting conditions, making a fixed lens a poor fit for many installations. - Varifocal lenses let integrators adjust focal length without moving the camera, which can improve field of view, target magnification and deployment flexibility. - Better lens selection can reduce mismatches between camera hardware, housing constraints and real-world surveillance needs.

What happened: - Fuzhou ChuangAn Optics Co., Ltd. (CHANCCTV) published a selection guide for varifocal lenses in security monitoring systems. - The guide highlights adjustable optics in 3.6–18 mm, 5–50 mm and 10–50 mm categories. - The company directs potential buyers to submit sensor format, mount type, focal length, working distance and other requirements for product matching and customized consultation.

The details: - CHANCCTV says its varifocal lenses use standard C and CS mounts and support sensors up to 12 MP. - The portfolio includes lenses for standard indoor and outdoor monitoring, perimeter coverage and longer-distance identification tasks. - A 6–18 mm lens is positioned for lobbies and parking garage entrances. - A 5–50 mm lens is positioned for perimeter monitoring, building exteriors and variable-distance checkpoints. - A 10–50 mm lens is positioned for longer-distance observation, including license plate and facial detail capture at gates. - The company publishes concrete optical data such as resolution limits, aperture values, IR correction and operating temperature ranges for specific models. - The CH906D is built for a 1/2.8-inch sensor, offers a 5–100 mm focal range at 5 MP, uses an F1.8 aperture, supports CS mount compatibility and includes IR correction for day/night performance. - The CH3693A is built for a 1/1.7-inch sensor, offers an 11–50 mm focal range at 8 MP, uses an F1.4 aperture, includes P-Iris control, motorized zoom and focus, and is rated from -25 to 85°C. - CHANCCTV accepts one-piece sample orders and says it has no minimum order quantity for initial evaluations. - The company says stock samples can usually ship in about 3 days. - The company says volume supply for 1,000 lenses has a lead time of about 15–20 days. - CHANCCTV says it responds to inquiries within 24 hours. - The company says it has been developing CCTV, varifocal, M12 and machine vision lenses since 2010.

Between the lines: - The guide is aimed at turning lens selection from a broad marketing choice into a specification-driven procurement process. - The emphasis on sample testing suggests CHANCCTV is trying to reduce compatibility problems before volume production starts. - Publishing exact model data can make it easier for integrators to compare options across projects and avoid vague performance claims.

What's next: - Integrators can send in application details for custom consultation and product matching. - CHANCCTV is positioning its support workflow as a path from early testing to full-scale procurement. - Future buying decisions will likely hinge on whether the lens specifications match the camera sensor, installation distance, housing and control requirements.

The bottom line: - CHANCCTV is pitching varifocal lenses as a specification-first solution for security monitoring teams that need flexibility, verified optics and faster integration.
