With comprehensive connectivity options, flexible output configurations, and advanced decoding capabilities, the DS-6916UDI is purpose-built for security operations centers, multi-site installations, and enterprise surveillance infrastructure requiring reliable, high-performance video management.

Key Features

• 16-channel simultaneous video decoding with flexible split-screen layouts (1/4/6/8/9/12/16/25/36)
• 4K video output support via HDMI (3840 × 2160@30 Hz) for ultra-high-definition display
• H.264 compression compatibility for efficient bandwidth and storage optimization
• Dual network interfaces: 2× RJ45 (10/100/1000 Mbps) + 2× optical (100 base-FX/1000 base-X) with combo configuration
• 16 HDMI outputs + 8 BNC outputs (via 2× DB15 connectors) for multi-display environments
• VGA and DVI-I inputs support 1080p@50/60 Hz and 720p input resolution
• Integrated two-way audio support (1× input, 1× output at 3.5 mm) for complete communication
• 8-channel alarm input/output for security automation integration
• RS-232 and RS-485 serial interfaces for device control and system integration
• PoE power supply with low power consumption (≤108 W) and dual 100–240 VAC support

Technical Highlights

Decoding Capacity: The DS-6916UDI decodes up to 128 channels across various resolutions: 8-ch at 24MP@30fps, 16-ch at 12MP@20fps, 32-ch at 8MP@30fps, 48-ch at 5MP@30fps, 80-ch at 3MP@30fps, and 128-ch at 1080p@30fps (3 Mbps). This scalability allows organizations to maximize their camera investments while maintaining flexibility for future expansion.

Connectivity & Networking: Dual RJ45 Gigabit interfaces combined with dual optical ports provide redundant, high-bandwidth network paths essential for mission-critical surveillance. The combo interface architecture ensures failover capability and network resilience.

Display Flexibility: With 16 HDMI outputs and 8 BNC outputs, the decoder supports complex multi-monitor configurations typical of large control rooms, enabling operators to customize viewing layouts for optimal situational awareness.

Applications

• Enterprise security operations centers and control rooms
• Multi-site corporate surveillance networks
• Government and critical infrastructure monitoring
• Transportation and traffic management systems
• Large-scale retail and hospitality installations
• Data center and facility management

The DS-6916UDI represents Hikvision's commitment to professional-grade video management infrastructure. Its standout feature is the dual-interface networking architecture—combining Gigabit RJ45 with optical fiber connectivity—which is critical for organizations requiring network redundancy and future-proofing against bandwidth constraints. The 128-channel decoding capacity across variable resolutions demonstrates intelligent resource allocation, allowing operators to mix camera types and quality levels within a single system.

The extensive output capability (16 HDMI + 8 BNC) addresses the reality of control rooms where multiple monitors serve different operational roles. Power efficiency (≤108 W) and PoE support reduce infrastructure overhead, while the -10 to 55 °C operating range qualifies the device for both climate-controlled facilities and challenging outdoor equipment enclosures. The inclusion of bidirectional audio and alarm I/O makes this a true hub for integrated security systems, not merely a video decoder.

Enterprises evaluating this device should note that 4K output is available only on odd HDMI interfaces, requiring careful monitor assignment planning.
