Import Cctv Fixed-Iris Manual Len — Buy in Bulk from Supplier in China

The CCTV fixed-iris manual lens offered by Shenzhen Seiko Star Corporation is a compact optical module designed for 1/3‑inch image sensors. It features a 3.6 × 4.8 mm CCD format and a fixed focal length of 6.0 mm. The lens mounts to a CS flange, provides a back focal distance of 9.3 mm and a maximum aperture of f/1.2. Key dimensions are 61.1 × 48.1 × 35.6 mm with a front element diameter of 14.0 mm and rear of 8.9 mm, and it operates between - 10 °C and 50 °C.

The optical assembly is typically constructed from high‑precision optical glass with an anti‑reflective coating, a standard approach for surveillance lenses. The manual iris provides a fixed range of 1.2, allowing consistent exposure without electronic control. Manual focus and zoom mechanisms give installers fine adjustment capability, matching the industry practice for fixed‑iris lenses used in low‑light CCTV systems. Tolerances for focal length are commonly ±0.1 mm and aperture variation ±0.05 f‑stop, which align with the specifications supplied.

This lens is suited for indoor and perimeter security cameras where a stable aperture and manual adjustment are preferred. System integrators and security equipment manufacturers in China and abroad source such modules for custom camera builds. The supplier lists the product dimensions and performance but does not disclose MOQ, pricing, incoterms or lead time, so buyers should request those details directly. Confirm packaging type and any required certifications before finalising the purchase.

Shenzhen Seiko Star Corporation is registered at Block 25, Unit 5/F Wangtang Industrial Estate, Xinwei Village, Xili Town, Nanchan District, Shenzhen 518055, China. It is classified as an imported tier supplier with a harbor trust tier, indicating that the company operates under standard import‑export compliance frameworks. The platform records a response rate of 0 % and no average response time, suggesting that the supplier has not yet engaged on the messaging system.

The company’s current listing focuses exclusively on a CCTV fixed‑iris manual lens, providing detailed optical parameters but omitting information on order minimums, pricing structure, or delivery schedules. Potential buyers should therefore treat the listing as a technical data sheet and seek direct quotation for commercial terms.
