Vivotek - FD939-EHTV - Vortex Premium Cloud 4K Outdoor AI IR Dome 4.3-9.8mm
Product Overview
The VIVOTEK FD939-EHTV is a high-performance 8MP (4K) fixed dome camera featuring a large 1/1.8" sensor and a 4.3~9.8mm motorized vari-focal lens for superior detail and remote focus control. It combines WDR Pro and 40-meter IR illumination to maintain ultra-high-definition clarity in complex lighting. Built for extreme conditions with IP66, IK10, and NEMA 4X ratings, it includes a massive 512GB industrial SD card, a built-in microphone, and full AI-driven analytics for proactive security monitoring.
Key Configuration
- • 4K Ultra-HD Imaging: Utilizes a large 1/1.8" progressive CMOS sensor to deliver 8MP (3840×2160) resolution, providing exceptional detail even at low bitrates (3 Mbps).
- • Smart Vari-focal Lens: Features a 4.3~9.8mm motorized lens with remote focus and P-iris, allowing for a flexible horizontal FOV from 110.4° to 45.1°.
- • Superior Low-Light Sensitivity: Captures color at 0.02 lux and black-and-white at less than 0.005 lux, supported by 40-meter Smart IR for total darkness.
- • Massive Edge Storage: Comes equipped with a pre-installed 512GB industrial-grade SD card, doubling the local recording capacity of standard models.
- • PoE Optimization: Operates efficiently via 802.3af Class 3 PoE, consuming a maximum of 12.4W with IR active, simplifying deployment across 4K networks.
Key Features
The FD939-EHTV is an 8MP (4K) powerhouse featuring WDR Pro and a versatile 3-axis adjustment for precision monitoring. It offers unique audio intelligence with audio detection and a built-in microphone, plus external I/O flexibility via the optional AO-015 cable. This NDAA/TAA compliant dome ensures enterprise-grade security with secure boot and signed firmware, while the AI Hub enables specialized detections like fall detection and PPE compliance for high-stakes environments.
Technical Context
Built for maximum network resilience, this camera supports WebRTC and TLS 1.2 with capacity for six concurrent clients. It is engineered to endure extreme environments, boasting NEMA 4X corrosion resistance and a wide operating range from -35°C to 60°C. With a non-condensing humidity tolerance of 98% and a full suite of global certifications UL, CB, CE, it provides reliable high-bandwidth performance in the most demanding climates.
Installation Notes
This heavy-duty metal unit measures Ø134 × 116 mm and weighs 990 g, carrying elite IP66 and IK10 protection ratings. The inclusion of an L-shaped wrench and alignment sticker simplifies the mounting process, though the AO-015 cable is required to unlock external alarm and audio functions. For long-term peace of mind, the hardware supports a warranty of up to 10 years when paired with specific licensing.
