Press Release Summary: Testing Cameras at Hot Environment Thermal tolerances of
cameras by Acumen exceed the stated value by 30%.

Press Release Body: Technical department of the Russian office of Acumen tests the
new extreme following the low temperature testing of the cameras on the surface of
dry ice. To determine the maximum operating temperature of the Acumen’s equipment
it was placed in a thermo-chamber which is capable of reaching temperatures above
400°C (752°F).
The following products were subjected to extreme heat: external high-speed cameras
Ai-SD85 and Ai-SD27, all-weather Ai-IR59, cylindrical Ai-BU45S, 19\" monitor
Ai-ML198N. Testing is especially important for the first three models since during
the summer all outdoor cameras are exposed to sun all day long. On the other hand
Mini-cameras and monitors could face overheating when placed in the high-heat
environment - metallurgical manufacturing. Additional reasons for this testing were
the fears of a possible overheating due to the black surface of the cameras, which
supposedly promotes greater heat in the sun.
The maximum operating temperature of the tested equipment in accordance with the
manufacturer\'s instructions varies from +50°C to +60°C (122°F to 140°F).

During the test the cameras were slowly heated for three hours, starting from the
room temperature. It is only when the temperature inside the heating chamber
reached 95°C (203°F) the cameras stopped transmitting video. Results were recorded
then the temperature was slowly reduced. When the temperature of the cameras cooled
to 92°C (197°F) the video transmission was re-established.

The maximum temperature to which the monitor was heated is 70°C. At that
temperature there were no visible differences in the quality of picture on display.

The conclusion of this experiment is that thermo-stability of the equipment by
Acumen is much higher than indicated in the characteristics of equipment’s values.
Cameras have an impressive stock of resistance to the extreme conditions.
