Moxa Video Networking Solution Facilitates Visual Management for HVAC system

Dec. 5, 2011 - PRLog -- . In addition to installing the ActiveX Control components, programming is also required to properly facilitate video displays and control functions. Unfortunately, the kind of programming required can pose problems for automation system integrators because they are not familiar with video technology. Moxa is working with one of its customer to develop a user-friendly tool with graphical interface for their system, an up-to-date BA solution of freely programmable management and automation stations for the full spectrum of building services applications, to save time and effort with programming video related functions. The system requirements are, activate live video displays when an alarm is triggered at a remote site, remote PTZ camera control is required, including direction control and presets control and audio on/off functions.

The customer is integrating a video surveillance solution with a SCADA system, with the main purpose to activate video images from a field site camera when an alarm is triggered. The customers building energy management system is used mainly for the HVAC (heating, ventilation, and air conditioning) system for building automation and control. In the past, if an alarm was activated, the system integrator of HVAC system needed to go to the field site to check what had happened. By activating the field site video with the alarm, the engineer can easily view the situation from the control centre and respond to the alarm quickly.
The system supports a number of different application scenarios based on the situation and requirements at the field site. This customer was looking for a tool that can be used to program and configure the video functions quickly and accurately. After conducting a detailed product survey, they chose Moxa’s VPort 351 industrial video encoder as the hardware solution, and worked with Moxa to develop a video genie for the system.

For this project, Moxa's VPort 351 video encoders are connected to PTZ cameras at the remote site. When intruders or a thermometer triggers an alarm, onsite video images will be sent to the control centre via Moxa's EDS-208A entry-level unmanaged Ethernet switch. The engineer then can observe the scene from the main computer and take proper action without needing to visit the site to troubleshoot an event each time the alarm is triggered, saving both time and money.
