Abstract
The invention discloses camera-shooting-preventing interference equipment. The interference equipment comprises an interference equipment body, wherein the interference equipment body is a parabolic-shaped outer cover; a metal film is plated on the inner surface of the outer cover; an infrared lamp bead is arranged in the parabolic focus of the outer cover; convex optical glass is mounted in the opening of the outer cover; the outer cover is connected with a base through a supporting rod; and an adjusting rotary knob used for adjusting the power of the infrared lamp bead is arranged on the base. The high-power infrared light generated by the infrared lamp bead can be sensed by a camera, however, the high-power infrared light cannot be sensed by human eyes, so that interference for camera shooting can be performed without influencing human eyes; the infrared light from the infrared lamp bead is reflected and refracted by the plated film on the inner wall of the shell and the convex optical wave, the transmitting distance can be increased, the interference range can be enlarged, and the interference effect can be reinforced, so that the purpose of privacy security protection of a user can be achieved.
Description
Technical field
The present invention relates to a kind of anti-bat jamming equipment of video camera.
Background technology
Video camera application in life is very extensive, and streets and lanes is seen everywhere.But there is the appearance of the news that leak is controlled by hacker overseas in certain monitoring device being as exposing for the previous period, everybody concern of the safety re-initiation of monitoring device.Monitoring device is once be controlled by undesirable, and its hazardness will be very serious, and in the safe little Zhi community of big extremely country important department, the personal secrets of people are all subjected to threaten.Additionally, various events of taking on the sly also emerge in an endless stream, the life of the public all there is certain harmful effect.So for the personal secrets protecting people, it is necessary to develop a kind of equipment that the camera function of CCTV camera can be carried out shielding processing.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, it is provided that a kind of anti-bat jamming equipment of video camera, CCTV camera and pinhole camera are carried out interference by this equipment use black light makes its camera function normally to use.
The anti-bat jamming equipment of video camera of the present invention includes jamming equipment main body, described jamming equipment main body is the outer housing of a parabolically face shape, outer cover inner surface metal-plated membrane, is provided with infrared lamp bead at its focal point place of outer housing, and housing opening place is equipped with convex optical glass；Outer housing is connected with base by support bar, and base is provided with the adjusting knob for regulating infrared lamp bead power.
In technique scheme, the Infrared wavelength that described infrared lamp bead produces is 760-1400nm；
Further, the Infrared wavelength that described infrared lamp bead produces is 940nm, entirely without red cruelly.
Described metal film is gold film, silverskin or aluminum film.
Described adjusting knob can be used to either on or off equipment, regulates infrared emission watt level.
During use, anti-bat jamming equipment being placed in photographic head just to place, after connecting power supply, rotary power adjusting knob opens equipment, can photographic head be disturbed.Or by anti-bat jamming equipment just to classified papers, window etc., may interfere with photographic head shooting so that it is image clearly cannot be obtained.Rotary power knob scalable infrared emission watt level.
Beneficial effects of the present invention is as follows: the Infrared High-Power light that infrared lamp bead produces can by photographic head perception, but can not by human eye perception, it is possible to when people not being impacted, video camera is taken pictures and disturbs.The infrared light that infrared lamp bead produces is after the reflection and refraction of outer casing inner wall plated film and convex optics ripple, it is possible to increases transmitting range, improves interference range, strengthens interference effect, thus reaching the effect of protection people's personal secrets.
Accompanying drawing explanation
Fig. 1 is the structural representation of the anti-bat jamming equipment of video camera.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
The anti-bat jamming equipment of video camera of the present invention includes jamming equipment main body, described jamming equipment main body is the outer housing 1 of a parabolically face shape, outer housing 1 inner surface metal-plated membrane, is provided with infrared lamp bead 2 at its focal point place of outer housing, and housing opening place is equipped with convex optical glass；Outer housing is connected with base 3 by support bar 5, and base 3 is provided with the adjusting knob 4 for regulating infrared lamp bead power.
In technique scheme, the Infrared wavelength that described infrared lamp bead produces is 760-1400nm；
Further, the Infrared wavelength that described infrared lamp bead produces is 940nm, entirely without red cruelly.
Described metal film is gold film, silverskin or aluminum film.
Described adjusting knob can be used to either on or off equipment, regulates infrared emission watt level.
Principles of the invention is: for human eye, it is possible to the spectral wavelength ranges of identification is between 400nm to 700nm.And for the photosensitive-member ccd sensor of photographing unit (video camera) camera lens with cmos sensor, they show spectrum more widely, at the wavelength more than 700nm, they also still can recognise that, so in time using more than the black light of 700nm, human eye can not perceive, but CCD with cmos sensor but can perception they.Particularly between working region 1100nm maximum near infrared region 780nm to base silicon material, CCD has maximum sensitivity with cmos sensor between 600nm to 900nm.Thus can be used below 390nm with the black light more than 700nm, pinhole camera to be interfered, it is made to simultaneously capture black light when shooting other picture, to be enough to interfere with the shooting of other pictures when the power of black light generator reaches sufficiently large time, thus reaching the anti-purpose taken pictures.
