Abstract

A monitoring video camera device capable of adjusting an infrared transmitting illuminant comprises a camera head (7), a decoding board (8), a spot light source (2), a convex lens (5) and a circuit board (3); and the monitoring video camera device further comprises a convex lens shift adjusting device which can move the convex lens (5) up and down vertically to the spot light source. The convex lens shift adjusting device can adjust the light emitted from the infrared transmitting illuminant by the convex lens or a planoconvex lens while the monitoring video camera device adjusts a focal length of the camera head and reach a distance equal to the focal length of the camera head of the monitoring video camera device so as to obtain clear pictures of objects or human at night.

Description

technical field [0001] The invention relates to a monitoring camera device for infrared monitoring, in particular to a monitoring camera device with an adjustable infrared emitting light source. Background technique [0002] In order to enable the spherical monitoring camera device to have an infrared monitoring function, the existing spherical monitoring camera device has a built-in infrared emitting light source, which allows the monitoring camera device to monitor at night to prevent loss of personal property. [0003] However, existing spherical monitoring camera devices with infrared monitoring functions have the defects of limited monitoring range and poor monitoring image quality, mainly because the camera in the monitoring camera device can realize shooting of objects at different distances by adjusting the length of the lens. In the daytime, due to the support of natural light, the camera can clearly shoot and record people or objects within the desired shooting dis...
