Returning the Average of Multiple Lines of Video
Purpose: Returns the average for multiple lines of video data (without pixel
coefficients applied). The number of lines to sample is set and
adjusted by the
css
command. The camera displays the Min.,
Max., and Mean statistics for the pixels in the region of interest (the
region of interest command is explained in section Setting a Region
of Interest (ROI)).
Syntax:
gla
Notes: 
Range defined using the spx and spw commands.

Analog gain, analog offset, digital offset, background subtract,
and digital system gain are applied to the data. FPN and
PRNU coefficients are not included in the data.

Values returned are in 12 bit DN.
Related Commands: spw, spx

4.14 Temperature Measurement
The temperature of the camera can be determined by using the
vt
command. This
command will return the internal chip case temperature in degrees Celsius. For proper
operation, this value should not exceed 75°C.
Note:
If the camera reaches 75°C, the camera will shutdown and the LED will flash red. If
this occurs, the camera must be rebooted using the command,
rc
or can be powered
down manually. You will not be able to restart the camera until the temperature is less
than 65°C. You will have to correct the temperature problem or the camera will shutdown
again. The camera allows you to send the
vt
(verify temperature) command while it is in
this state.
4.15 Voltage Measurement
The command
vv
displays the camera‘s input voltage. Note that the voltage
measurement feature of the camera provides only approximate results (typically within
10%). The measurement should not be used to set the applied voltage to the camera but
only used as a test to isolate gross problems with the supply voltage.
