Problems solved by technology

But it still has disadvantages. For example, there are only two to four focal lengths to choose from, and it is impossible to focus at any distance, which wastes the viewing angle and light source; The infrared lamp generates too much heat, which will easily cause the internal temperature of the infrared dome camera to rise, which poses a threat to the normal operation of the electronic components in the infrared dome camera

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with specific embodiments and the drawings of the specification.

[0024] figure 1 An infrared dome camera 1 in some embodiments of the present invention is shown. The infrared dome camera 1 can be applied to a closed-circuit television monitoring system, and it can include a main control unit 10, an integrated movement 20, an infrared lighting unit 50, and The light angle adjustment unit 60. The integrated movement 20 can automatically focus on two or more different distance positions (for example, 2 to 256 different positions) to provide two or more different monitoring distances. The infrared illuminating unit 50 cooperates with the integrated movement 20 (for example, the infrared illuminating unit 50 is distributed around the lens of the integrated movement 20), and is used to provide infrared illumination for the integrated movement 20 at night or in places with low light. . The light ou...

Abstract

The invention relates to an infrared dome camera comprising an integrated core and an infrared lighting unit matched with the integrated core. The integrated core is capable of automatically focusing on at least two positions at different distances. The infrared dome camera further comprises a master control unit and a light-emitting angle adjusting unit. The master control unit is used for obtaining the focal length information when the integrated core focuses at any one of the at least two positions at different distances, outputting a control signal to the light-emitting angle adjusting unit according to the focal length information and controlling the light-emitting angle adjusting unit to adjust the light-emitting angle of the infrared lighting unit.

Description

Technical field [0001] The invention relates to the field of security monitoring, and more specifically, to a camera. Background technique [0002] In the construction of closed-circuit television monitoring systems, many cameras on the market now generally can well meet the monitoring needs during the day, and many cameras have also made great progress in horizontal resolution and color reproduction. However, when the ambient illuminance becomes very low or there is no light at all, it becomes more difficult for the camera to capture images that meet the monitoring requirements. If the method of enhancing white light lighting is adopted to solve the problem, a large amount of power consumption will cause the loss of resources and increase the cost. At the same time, increasing the ambient lighting is not conducive to the concealment of the monitoring equipment, and can even remind those malicious attempts to avoid the effective monitoring range. Bad behavior or criminal activit...
