"VSR" Module - Video Overlay, Data Synchronization, Sensor Expansion and Recorder Module.


Bringing flexibility and expandability to Data Logging Systems...

The �VSR� Module facilitates the use of video input and data synchronization to a recording device and for subsequent analysis when the data is downloaded to a PC running DataPro with Synchronized Video.

The "VSR" Module connects between a remote mounted camera and a digital video recorder, such as the Stack harsh environment DVR.

Direct Sensor inputs and recording or data logging capability is also integrated.

This module provides 0.5 Mbytes of solid-state memory and records up to 20 channels at 50Hz sampling frequency per channel.

Any channel that is monitored by the Stack systems can be overlaid into the video picture in real-time. The channel can be formatted with a text label and with the channel units displayed if required.

In addition the "VSR" Module features an intelligent alarm capability so that whenever any monitored parameter exceeds a threshold level, a plain text warning message is �popped up� on the recorded video screen.

The "VSR" Module provides control switch inputs for manually starting & stopping data logging and for adding Event Markers to the data.

In addition this module has direct sensor inputs for 5 low resolution voltage inputs, a dedicated RPM signal input and 2 pulse inputs.
