Vivotek CD9381-HNTV 5MP Vandal-Proof High-Angle Corner Indoor Dome IP Camera

Vivotek CD9381-HNTV 5MP Vandal-Proof Corner Dome Camera

The Vivotek CD9381-HNTV is a high-resolution, vandal-resistant corner dome IP camera engineered for demanding indoor surveillance applications. Designed for institutional environments including detention centers, psychiatric wards, and healthcare facilities, this camera delivers 5MP resolution with intelligent analytics in a compact, impact-resistant form factor that minimizes visual intrusiveness while maximizing spatial coverage.

Key Features

• 5MP (2560×1920) progressive CMOS sensor for superior detail capture
• Vandal-proof IK10-rated dome construction with corner-mount optimization
• Motorized vari-focal lens (2.8–8mm) with remote focus and 48x digital zoom
• WDR Pro technology with 120dB dynamic range for high-contrast environments
• Removable IR-cut filter with dual IR illuminators (10-meter effective range)
• Two-way audio with built-in microphone and full-duplex capability
• Deep learning-powered VCA for people/vehicle detection and attribute extraction
• PoE-powered (max 10.36W) with optional DC 12V or AC 24V connectivity
• MicroSD/SDHC/SDXC card support plus NAS recording integration

Technical Specifications

Imaging Performance: The 1/2.7" progressive CMOS sensor delivers 30fps at full 5MP resolution with WDR Pro enabled, scaling to 60fps in 1080p mode. Motorized vari-focal optics (f1.8–f2.78) provide 95° horizontal wide-angle to 41° telephoto coverage. Minimum illumination reaches 0.085 lux in color mode and <0.005 lux in B/W, enabling effective surveillance in near-darkness with IR assistance. The fixed-iris design and Smart IR technology optimize exposure across extreme lighting variations typical in institutional settings.

Advanced Analytics: Embedded hardware deep learning accelerator powers intelligent motion detection, intrusion detection, loitering alerts, line-crossing detection, and people/vehicle attribute extraction (gender, clothing color, vehicle type). License-enabled applications include running detection, parking violation detection, and restricted zone monitoring.

Security & Connectivity: Triple video streams with H.265/H.264/MJPEG compression, ONVIF Profile G/S/T compliance, and comprehensive security protocols including HTTPS, IEEE 802.1x, Trend Micro IoT protection against brute-force and cyberattacks. Supports up to 10 concurrent clients.

Durability: Operating range of -10°C to 55°C (IR off) or -10°C to 40°C (IR on), with 98% RH non-condensing tolerance. CE, FCC, UKCA, and RCM electromagnetic compliance certification.

Applications

Ideal for secure facilities requiring covert, high-resolution surveillance: correctional institutions, behavioral health units, emergency departments, and sensitive access zones. Corner mount design eliminates blind spots in confined spaces while discrete profile reduces patient/detainee awareness, supporting therapeutic environments and operational transparency.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The CD9381-HNTV addresses a critical gap in institutional surveillance—balancing security integrity with facility aesthetics and occupant psychology. The IK10 vandal rating and corner-optimized optics make it exceptionally difficult to disable or obstruct, while the 5MP sensor and WDR Pro ensure forensic-grade detail even in high-contrast detention or medical environments where lighting varies dramatically. The embedded deep learning accelerator eliminates reliance on external analytics servers, reducing latency and infrastructure overhead.

Two-way audio and Smart IR (adaptive, non-blooming) support de-escalation protocols common in behavioral health settings. PoE efficiency (max 10.36W) simplifies infrastructure while redundant power options (DC 12V, AC 24V) provide resilience. ONVIF compliance and triple streaming enable seamless integration into existing VMS ecosystems.

The motorized vari-focal lens with remote adjustment is particularly valuable for retrofits where precise framing must be achieved post-installation without ladder access.
