CAUTION!

• THE LOW VOLTAGE/CURRENT CIRCUITS AND HIGH VOLTAGE/ CURRENT

CIRCUITS ARE IN THE NETWORK CAMERA CIRCUIT. THE QUALIFIED ELECTRICIAN

SHOULD DO THE WIRING NOT BY YOURSELF. INCORRECT WIRING COULD

DAMAGE NWTWORK CAMERA. YOU COULD RECEIVE THE FATAL ELECTRIC

SHOCK.

• THE EXTERNAL I/O IS NOT CAPABLE OF CONNECTING DIRECTLY TO DEVICES

THAT REQUIRE LARGE AMOUNTS OF CURRENT. IN SOME CASES, A CUSTOM

INTERFACE CIRCUIT (CUSTOMER PROVIDED) MAY HAVE TO BE USED. SERIOUS

DAMAGE TO NETWORK CAMERA MAY RESULT IF A DEVICE IS CONNECTED TO

THE EXTERNAL I/O THAT EXCEEDS ITS ELECTRICAL CAPABILITY.
