4.8. Advanced Smart-Temp
The EX4 Plus 35 System incorporates several advanced features not found in any other
system on the market such as the Advanced Smart-Temp™. Advanced Smart-Temp and
the built-in heater ensure safe operation of the DVR over a wide temperature range.
Advanced Smart-Temp monitors the temperature inside the DVR to ensure the hard
drive operates in a safe environment. In many areas, the temperature drops well below
40°F (4°C) and quite often below 32°F (0°C). Most computer hard drives are designed to
work from about 40°F (4°C) to about 120°F (49°C).
