POWER: Indicates the camera is receiving power.

SYS: Blinks when all is normal and camera is connected to USB.

TEC: Light will only show if the TEC is active and the 12v supply is plugged in. If the supply voltage is too low then it may not light up. Some camera models will work without TEC because the main board is powered by the USB cable.

FAN: Shows the fan is running. On TEC cameras the fan will run automatically when TEC is enabled. If the fan does not run when TEC light is on, switch off the camera and contact support.
