Hanwha SMT-3231PV 32" AI Public View Monitor

The Hanwha SMT-3231PV is a sophisticated 32-inch AI-enabled public view monitor that seamlessly integrates surveillance, display, and communication functions into a single enterprise-grade solution. Engineered for retail, transportation, municipal, and commercial environments, this monitor combines a built-in 2MP IP camera with intelligent video analytics and a bright, high-contrast 1080p FHD display to deliver situational awareness and dynamic public engagement simultaneously.

Key Features

• 32" Full HD (1920×1080) LED display with 400 cd/m² brightness and 1300:1 contrast ratio
• Built-in 2MP CMOS IP camera with 3.06mm fixed lens and 107.7° horizontal field of view
• AI-powered analytics: face/person detection, object classification, virtual line crossing, intrusion detection, and loitering alerts
• Business intelligence features: people counting, queue management, and heatmap generation
• 120dB Wide Dynamic Range (WDR) with advanced noise reduction (SSNR V, WiseNR II)
• Dual HDMI inputs with Picture-in-Picture (PIP) and Picture-by-Picture (PBP) capability
• Integrated dual 2W speakers for two-way audio communication
• H.265/H.264/MJPEG video compression with WiseStream III smart codec
• MicroSD/SDHC/SDXC local storage (up to 256GB) with event-triggered recording
• Multiple viewing orientations: landscape, portrait, and 90°/270° hallway mode
• Motion detection (8 polygonal zones) and privacy masking (32 quadrangle zones)
• VESA mount compatibility (100×100mm, 200×100mm, 200×200mm)
• Powered via DC24V or High Power over Ethernet (802.3bt)
• ONVIF Profile S/G/T/M and SUNAPI compatibility for seamless system integration

Technical Highlights

With a 25ms response time and 178° viewing angles (horizontal and vertical), the display delivers clear, responsive visual performance across wide indoor spaces. The camera's F1.6 aperture and 0.03Lux minimum illumination enable reliable operation in low-light conditions, while backlight compensation, electronic shutter control, and digital PTZ provide flexible image adjustment for varying environments. The monitor's 30,000-hour panel life and robust operating range (0° to +40°C) ensure long-term reliability in 24/7 deployments.

Security is built-in with secure boot, signed firmware, encrypted SD card partitions, HTTPS/SRTP communication, and 802.1X network authentication. Multi-level user access controls, audit logging, and IP-based access policies protect sensitive footage and system configurations.

Applications

Ideal for retail environments requiring real-time people counting and queue monitoring; public transit stations needing intrusion and loitering detection; command centers demanding simultaneous display and camera feed management; retail loss prevention with integrated face detection; and facilities management requiring networked surveillance with local recording redundancy.

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

The SMT-3231PV addresses a specific market gap: the need for an all-in-one device that eliminates separate camera and display infrastructure. By embedding a capable IP camera directly into the monitor bezel, organizations reduce cabling complexity, power consumption, and deployment footprint while gaining immediate visual feedback and local analytics processing. The dual HDMI inputs with PIP/PBP capability allow operators to overlay external camera feeds or content alongside the built-in camera stream, enabling flexible control room and digital signage workflows.

The AI engine's on-device processing (person/face detection, virtual line crossing, intrusion detection) reduces reliance on external analytics servers, lowering latency and improving reliability. WiseStream III compression and local microSD recording provide bandwidth efficiency and failover protection. ONVIF/SUNAPI support ensures interoperability with third-party management platforms, while the 802.3bt PoE option simplifies cable runs in retrofitted facilities. The combination of high brightness (400 cd/m²), wide viewing angles (178°), and 120dB WDR makes this monitor suitable for both indoor and bright ambient environments, a rare feature in integrated monitor-camera units.
