The VIVOTEK FD839-EHTV-V2 is a professional-grade 5MP dome camera featuring a 2.8~12mm motorized vari-focal lens with remote focus for precise field-of-view adjustments. It combines WDR Pro and powerful 40-meter IR illumination to deliver clear 2560×1920 video in any lighting condition. Built to withstand extreme environments, it carries IP66, IK10, and NEMA 4X ratings. It comes equipped with a pre-installed 256GB industrial SD card and full-duplex two-way audio for comprehensive site security.
The FD839-EHTV-V2 is an NDAA/TAA-compliant dome featuring WDR Pro and a highly flexible 3-axis adjustment (350° pan, 80° tilt) for versatile positioning. It supports full-duplex two-way audio with a built-in microphone and offers expanded I/O capabilities for digital inputs/outputs via an optional cable. Security is prioritized through Secure Boot and video encryption, while the AI Hub enables advanced, specialized analytics such as Personal Protective Equipment (PPE) and fall detection.
This robust camera is designed for extreme climates, maintaining operations in temperatures as low as -35°C and high-humidity environments up to 98% RH. It supports secure streaming via WebRTC and TLS 1.2, accommodating up to six concurrent clients for simultaneous live monitoring. The hardware is backed by rigorous industrial certifications, including NEMA 4X for corrosion resistance and IK10 for high-impact protection.
Measuring Ø134 × 116 mm and weighing 990 g, this heavy-duty metal dome is built for longevity and includes a dedicated L-shaped wrench for secure assembly. The AO-015 cable is essential for users requiring external audio I/O or alarm integration. The unit is optimized for CAT5e or CAT6 cabling and, depending on the specific license selected, can be covered by a warranty of up to 10 years.
