4x1 HDCCTV (HD-SDI) Switcher Inquiry



The KanexPro SDI switcher is a 4 input, one output switcher designed to switch four SDI,HD-SDI or 3G-SDI sources to one SDI monitor or display output. For optimum performance the SDI switcher can be controlled using RS-232 to switch the inputs. The 4X1 switcher includes  re-clocking technology which drives the signal at longer distances and supports SDI, HD-SDI and 3G-SDI signals. It supports multi-stage cascading for adding more SDI components and switchers.

Ideally used with SDI based HDCCTV surveillance systems, rental & staging facilities, post-production, TV studio, digital cinema, or other A/V applications where you need to switch and split from an SDI camera or other device equipped with 3G/HD/SD-SDI outputs to one SDI-compliant display or video processor.
