Hanwha CMVR-420 Wisenet SKY Compact NVR

Hanwha CMVR-420 Wisenet SKY Compact NVR

The Hanwha CMVR-420 is a compact, rack-mountable network video recorder purpose-built for small to mid-scale security deployments. Built on Hanwha's Wisenet SKY platform, this embedded Linux-based system delivers flexible camera support, reliable storage, and cloud analytics integration in a space-efficient 1U form factor. The CMVR-420 bridges the gap between entry-level and enterprise surveillance, offering scalability without unnecessary complexity for businesses, retail locations, and distributed facilities.

Key Features

• Support for up to 15 cameras at 1MP or 12 cameras at 4MP resolution
• Scalable to 30 cameras at 1MP and 25 cameras at 4MP with higher capacity configuration
• Cloud analytics capability for up to 5 intelligent video events
• Dual gigabit ethernet RJ-45 network ports for redundancy and bandwidth optimization
• Multiple video output options: VGA, DVI, HDMI, and DisplayPort for flexible multi-monitor integration
• Dual USB 3.0 front ports for rapid data transfer and peripheral connectivity
• Internal 65W power supply with wide input voltage range (100-240V AC)
• Embedded Linux operating system for reliability and performance
• Compact 1U rack mount design with included mounting brackets for standard server racks

Storage & Recording Capabilities

The CMVR-420 accommodates internal hard drives up to 4TB, delivering 15 days of continuous recording for 15 cameras at 1MP resolution. Higher-capacity 10TB configurations extend retention to 20 days for 30 cameras at 1MP, allowing organizations to scale storage based on retention policies and camera count requirements. This flexibility supports both compact single-site deployments and expanded multi-camera installations without requiring external storage systems.

Physical Design & Environmental Specifications

Measuring 16.81" × 9.88" × 1.75" (427mm × 251mm × 45mm) and weighing approximately 9 lbs, the CMVR-420 fits seamlessly into standard server racks or on shelf/tabletop installations. The metal chassis in black provides durability in professional environments. Operating temperature range of 32°F to 95°F (0°C to 35°C) and humidity tolerance of 0% to 70% RH (non-condensing) ensure reliable performance in most indoor deployment scenarios. Full certifications including FCC, UL, PSE, CE, CCC, REACH, RoHS, and NDAA compliance demonstrate suitability for regulated and government-adjacent installations.

Ideal Applications

The CMVR-420 serves retail chains, office buildings, small-to-medium manufacturing facilities, educational institutions, and distributed enterprise locations requiring reliable video recording without on-site IT infrastructure. Cloud analytics integration enables remote event monitoring, while embedded Linux stability minimizes maintenance overhead.

The CMVR-420 represents a pragmatic mid-market positioning. Its 1U form factor and included rack brackets address dense deployments in server rooms or network closets. The dual gigabit ports support network redundancy without additional hardware, critical for facilities where recorder uptime drives compliance or operational requirements.

The choice between 4TB and 10TB HDD configurations allows cost-conscious buyers to right-size storage; 15 days at 1MP is typical for most regulatory retention policies. Cloud analytics capped at 5 events is sufficient for intrusion detection, loitering, and line-crossing on modest camera counts, though AI-heavy deployments may require the higher-tier 10-event variant. The absence of mention of 8TB options or RAID redundancy suggests this is not engineered for mission-critical environments; organizations requiring sub-second failover should evaluate enterprise-class alternatives.

Hanwha's Wisenet SKY ecosystem integration provides a pathway to scale storage, analytics, and multi-site management as needs grow.
