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 shut down 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 shut down again. The camera allows you to send the vt (verify temperature)
command while it is in this state.
