Key Features

• Elite 4-Channel SDI Input Array Consolidate your workflow. The BM4500S handles four simultaneous SDI feeds (including 3G-SDI Level-B) in a single compact chassis. Perfect for multi-camera live production, campus-wide broadcasting, and synchronized recording.
• Hybrid 4K30 & 1080p60 Performance Future-proof your acquisition. Channels 1 and 2 support high-resolution 4K30 input, while all channels provide broadcast-standard 1080p60 encoding, offering the flexibility to manage mixed-resolution sources with ease.
• SRT & Private Low-Latency Protocol Master the modern network. Fully optimized for SRT (Secure Reliable Transport) to ensure low-latency, secure video over unpredictable public networks. For closed-loop environments, Unisheen’s Private UTP protocol delivers ultra-low latency of less than 100ms.
• Flexible Audio Integration Beyond embedded SDI audio, the BM4500S features two dedicated 3.5mm analog inputs, allowing for external audio mixing, commentary, or separate audio-only streaming for podcasts and technical monitoring.
• Advanced Hardware Preprocessing Pristine visual quality is standard. The unit features built-in hardware for Image Enhancement, Flip, Mirror, Rotate, and Precision Clipping, alongside specialized De-interlacing for legacy broadcast signals.
• Industrial Gigabit Networking & Reliability Equipped with a 1000M Gigabit Ethernet port for high-bandwidth data acquisition. The fanless, energy-efficient design (≤15W) ensures 24/7 stable operation in server rooms and mobile broadcast kits (9.06 x 5.91 x 1.73 inches).
