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.
