VT211-A20B-B0

Serving Security Industry with Technology and Dedication

Network Cameras

VT211-A20B-B0 Series is a Starlight WDR Intelligent IR IP fixed camera featuring 1/2.8" progressive scan CMOS sensor and built-in 2.0 megapixel 2.8-12mm Motorized Vari-focus lens. With H.265/H.264/M-JPEG compression format utilized, this camera can output HD full-frame videos with the resolution of 1080p@30fps. The built-in dot matrix IR illuminators allow a maximum of 50 meters night vision distance.

The camera supports the function of strengthening ROI encoding, so as to improve the image quality of key areas under low-band network environment.

The camera supports three simultaneous video streams. It also provides motion detection, privacy mask, video mask alarm, image snapshot, local recording, noise deduction, backlight compensation and WDR functions. Alarm can be associated with email sending and FTP upload.

Compact structure makes it easy to install.

VT211-A2-B0 series are widely used in normal buildings, supermarkets, hotels, shops, parks, schools, factories, warehouses, underground parking lots and other high-resolution surveillance applications
