The SD9374-EHL is VIVOTEK’s latest professional IR speed dome camera with 4MP resolution, specifically designed to enhance video surveillance in large coverage areas. Equipped with 250M IR illuminators and a 36x optical zoom lens, the SD9374-EHL provides a crystal clear image with 2560×1440 pixels in the most challenging situations. The SD9374-EHL also adopts VIVOTEK’s Smart IR II technology, Vari-Angle IR. VIVOTEK’s Vari-Angle IR provides smooth vari-angle adjustment of the IR illuminators, allowing broad coverage FOV and highly uniform IR intensity while avoiding hotspots traditionally associated with IR illumination.

The SD9374-EHL utilizes H.265 compression technology. When combined with VIVOTEK’s Smart Stream III technology, users can obtain ultra low bandwidth while maintaining high image quality compared to H.264 compression. By combining 4MP resolution with H.265, IR illuminators, Vari-Angle IR, WDR, and 36x optical zoom, the SD9374-EHL is able to capture fine details at top-notch quality, 24 hours a day, 7 days a week. VIVOTEK further strengthens the camera performance with an IP66- and NEMA 4X-rated housing to protect the camera against rain, dust, and corrosion. The SD9374-EHL has a wide operating temperature range from -40°C to 55°C, ensuring continuous operation under the most extreme weather conditions and hazardous environments. This makes the SD9374-EHL ideally suited to monitor wide open spaces such as ports, highways, city surveillance, and parking lots where high-level precision is required.

As with all VIVOTEK true day/night cameras, the SD9374-EHL features a removable IR-cut filter, maintaining clear images 24 hours a day. Audio detection is included by recognizing changes in ambient noise. The SD9374-EHL also includes a MicroSD/SDHC/SDXC card slot and supports up to 30 fps in 4MP. For the most demanding outdoor surveillance application, there is nothing that compares to the VIVOTEK SD9374-EHL.
