A monitoring camera with a far infrared capability has a cylindrical body ( 10 ), a lens hood ( 20 ), a luminous body ( 30 ) with multiple far infrared light emitting diodes (LEDs) and a lens cover ( 40 ). The lens hood ( 20 ) is a hollow cylinder and is divided into an inner segment and an enlarged outer segment ( 23 ) communicating with the inner segment. The enlarged outer portion ( 23 ) provides an enlarged compartment to hold a larger luminous body ( 30 ), which can hold more far infrared LEDs so the monitoring camera can see object at greater visual distances. Additionally, the field of vision the monitoring camera is also greater.
