Feature:1. 4 In 1 Out: The SDI switcher allows you to output 4 SDI signals to a single display, with easy switching between input sources using the included remote control. It supports high definition resolutions of up to 1080P at 60Hz for both input and output.2. 4 Monitoring Inputs: With 4 SDI interface signal inputs for monitoring cameras, you can connect and switch between multiple cameras seamlessly. The SDI interface output can be connected to TVs, projectors, or monitors for real time monitoring.3. Signal Formats: The switcher supports SD SDI (270Mbps), HD SDI (1.485Gbps), and Full HD 3G SDI (2.97Gbps) video formats, ensuring compatibility with a wide range of devices and systems.4. Enhanced Features: Equipped with built in equalizers, reclockers, and cable drivers, the SDI switcher ensures optimal signal quality and stability. It supports maximum cable lengths of 400m for SD SDI, 200m for HD SDI, and 100m for 3G SDI, allowing flexibility in your setup.5. Plug and Play: The switcher automatically detects different SDI signals. When a valid SDI input signal is detected, the LED indicator lights up in green, providing user friendly experience for seamless switching and operation.Specification:Item Type: SDI SwitcherMaterial: Aluminium AlloySDI Input Ports: BNC SDI x 4SDI Output Port: BNC SDI x 1SDI Standards: Compatible with SMPTE 424M, SMPTE 292M and SMPTE 259M CSDI Sign Formats: SD SDI, HD SDI, 3G SDISDI Speed: 143 2970MB/SSDI Impedance: 75SDI Input Resolution: 480i at 60Hz, 576i at 50Hz, 720P at 50Hz, 720P at 60Hz, 1080i at 50Hz, 1080i at 60HZ, 1080P at 24 at 25 at 30 at 50 at 60HzSDI Output Resolution: 480i at 60Hz, 576i at 50Hz, 720P at 50Hz, 720P at 60Hz, 1080i at 50Hz, 1080i at 60HZ, 1080P at 24 at 25 at 30 at 50 at 60HzSDI Sign Output Range: 800mVp pProduct Size: Approx. 170 x 88 x 24mm / 6.7 x 3.5 x 0.9inTemperature: 0~60Remote Control Battery: CR2025 x 1 (not included).Package List:1 x Host1 x Remote Control (Shipped without Battery)1 x Power Adapter1 x English Instruction Manual
