Network Cameras

VT231-A2-A3 series is our newly introduced high definition infrared network dome camera that supports 1920x1080@30fps HD network video output. It adopts H.265/H.264/M-JPEG encoding and its output provides excellent definition and color revivification degree which enables the acquisition of rich and accurate details so as to effectively guarantee smart analysis accuracy.

The cameras carry smart functions and support wire cross, instruction as well as scene change, defocus, too-dark and too-bright detecting. With its safe, professional and reliable smart analysis, it can satisfy various upmarket applications.

This product adopts large power LED infrared lamps, infrared wave length 850nm, long night vision distance up to 120m, strong illumination. The IR lamps can turn on or off automatically based on environmental lighting conditions or can be adjusted manually. The IR illumination allows flexible adjustment so as to reduce IR lamp calorific value and extend its service life.

User-friendly GUI interface design allows users to perform dome PTZ control easily via network and to configure detailed camera parameters settings. At Web interface users can perform dome camera settings and operations by using a mouse which is more convenient than the traditional keyboard control. It also supports area zoom and image PTZ function.

VT231-A2-A3 series dome cameras also feature general dome functions such as preset, pattern, autopan, autoscan, time tour and normal tour.
