Abstract

Disclosed is a monitoring camera with a filtering element. The monitoring camera includes a rotary support, a built-in camera and a protective cover. A rotary control mechanism is arranged on the rotary support. The camera is connected with the rotary control mechanism so that the camera can be controlled to be capable of rotating within a range of 360 degrees. The monitoring camera is characterized in that the built-in camera sequentially includes a first lens, the focal length of which is f1, a second lens, the focal length of which is f2, the filtering element 40 and an image sensor chip used for receiving images. The refraction index of a material used by the first lens and the second lens is 1.5 to 1.7 and the first lens satisfies a relational expression: -9<f1 / f<-0.4 and the second lens satisfies a relational expression: 1.2<f2 / f<4.8. The f is the focal length of the whole optical system.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a surveillance camera with a filter element. Background technique [0002] Security monitoring technology involves all aspects of life and production, such as: subways, highway transportation, hotels, banks, etc. [0003] Patent document CN201577130U discloses a security monitoring camera with an emergency power supply, including an adapter unit, an internal power storage unit and an external voltage detection unit. The utility model discloses a security monitoring camera with an emergency power supply, which can work normally when there is a problem with the external power supply, so as to ensure that the place required by the customer can be monitored at any time, which greatly improves the security monitoring. The monitoring ability of the camera enhances the customer's product use experience, and at the same time ensures the product market share of the security monitori...
