The Field Mobile Video Image Acquisition and Recording Set (VIARS-FM) is designed to provide the User with the full autonomous capability to acquire, to record, to display and to time stamp video images frames in field conditions. Different optical filters can be integrated into the objective lens for capturing images in various spectral ranges. The VIARS-FM can be powered from 220VAC (protected by safety relay), 24VDC (protected by fuse) or from internal rechargeable battery according to available voltage sources. The internal battery provides at least 3 hours of system operation. The total system power consumption is less than 40 Watts.

The VIARS-FM comprises of the following components:

Rigid sealed case
• B/W Video Camera
• 10 – 120 mm ZOOM Objective with Auto Iris
• 8" Video Monitor with sun shield
• Digital Video Recorder
• Precision GPS based Time Stamping with antenna
• Ni-Me Battery with charger
• Ni-Me Battery Voltage Monitor
