The Internet of Things technology is widely used in intelligent building industry. The system takes LABVIEW as the develop-ment software,design of virtual experiment system based on office building for video monitoring,implementation of video surveillance system. Real-time monitoring system can be used for simulation of building equipment operation and staff activities and subsequent query function,achieving design and development of virtual experiment system software for video monitoring based on Internet of Things. Sys-tem front-end is camera input and the back-end is device for displaying,recording and controlling. The control device realizes the control for the front camera and the back-end device of displaying and recording,implementation of control for the front camera,lens,and PTZ, and the back-end device of displaying and recording,and linkage control with intrusion alarm system and fire alarm system. The video data file and playback technology is used to realize analog video monitoring data.%物联网技术在智能建筑行业的应用无处不在。该系统采用LABVIEW为开发软件，设计以办公楼为对象的视频监控虚拟实验系统，实现视频监控安防系统的功能。系统具有仿真楼内各设备的运行及人员活动的实时监视和事后查询功能；完成基于物联网的远程视频监控虚拟实验系统软件的设计开发。系统的前端为视频摄像输入，后端是显示、记录和控制装置。通过控制装置对前端摄像机和后端显示及记录设备进行控制，实现对前端摄像机、镜头、云台的控制，对后端显示、记录设备的控制，与入侵报警系统和火灾报警系统的联动控制，采用视频数据文件回放技术，实现视频监控数据的回放。
