In order to serve customers with better facilities, Shenzhen Crown Tech ( Shenzhen Ke Nuo En Tech) was established few years later. With strong ability of research and development, Crown Tech developed advanced vari-focal high speed dome cameras and box integrated cameras compatible with Sony zoom camera blocks. Meanwhile the development of the interface boards tailored for Sony FCB zoom cameras allows our products to have their own sales chain, forming a one-stop service. We continue to develop more advanced products and expand our services to diverse industries with best products. Our standing inventory is extremely important for your production and R&D. Our strong technical background and our mature after-sales maintenance are the best reasons for you to choose us.
