The regulating course on surface；The regulating course includes the closed sandwich between Double-layered transparent thin layer and the Double-layered transparent thin layer, described
Silver ion solution is full of in closed sandwich, and former and later two outer surfaces of the Double-layered transparent thin layer are coated with indium oxide layer respectively
Tin film, and indium oxide tin film described in two layers is respectively and electrically connected to two output ends of the same power supply module；The power supply mould
Block when the monitoring camera amplifies visual field middle section, make two layers described in indium oxide tin film power down, remaining time
To two layers of indium oxide tin film power supply.
Preferably, uneven thickness or tin indium oxide film surface are covered with hole everywhere on the surface of each layer indium oxide tin film
Hole.
Preferably, the power supply module is to the indium oxide tin film output pulsation direct current, so that two layers of tin indium oxide
The fluctuation electric field of orientation is formed between film, to make the silver ion continuous shaking for being attached to transparent lamina inner surface, with further
Improve the degree of disorder of the reflection to infrared light.
Preferably, the power supply module is before making the indium oxide tin film power down, it is first to tin indium oxide described in two layers
Film provides a backward voltage keeps the regulating course quick so as to be attached to the silver ion fast-falling of transparent lamina inner surface
Transparence is presented.
The beneficial effects of the present invention are: the adjustable night vision monitoring camera is in normal monitoring, as described in two layers
Indium oxide tin film be in energized state, orientation electric field is formed in the regulating course, the silver in silver ion solution for keeping it internal
Ion releasing, and it is attached to wherein layer of transparent coating inner surface, the uniformity and stability being precipitated due to silver ion are poor,
The mirror surface formed on transparent lamina is more coarse, thus to infrared light formed the degree of disorder it is higher, be similar to irreflexive reflection, thus
So that the light-gathering of each infrared generator is in reduced levels, form broader infrared light light filling range in front of camera lens, to obtain
The biggish night vision visual field；And when the monitoring camera amplifies operation to visual field middle section, indium oxide described in two layers
Tin film power down, the electric field in the regulating course disappears at this time, and silver ion is detached from transparent lamina inner surface, is transparent regulating course
State at this time reflects infrared light by the base being made of curved mirror at the regulating course rear, makes the directionality of reflected light
It greatly improves, concentrates on the visual field center of the camera lens, thus when amplifying visual field middle section, clarity with higher.

Specific embodiment
In Fig. 1-embodiment shown in Fig. 4, which includes body 1, before the body 1
End is equipped with camera lens 2, is evenly equipped with infrared generator 3 around the camera lens 2；Each infrared generator 3 includes reflector 31, Yi Jishe
Infrared diode 32 in 31 center of reflector；The reflector 31 includes base 311 being made of curved mirror, and be set to base
The regulating course 312 on surface；The regulating course 312 is as shown in figure 4, include that Double-layered transparent thin layer 3121,3122 and the bilayer are saturating
Closed sandwich 3123 between bright thin layer 3121,3122, is full of silver ion solution in the closed sandwich 3123, and the bilayer
Former and later two outer surfaces of transparent lamina 3121,3122 are coated with indium oxide layer tin film 3124,3125 respectively, and described in two layers
Indium oxide tin film 3124,3125 is respectively and electrically connected to two output ends of the same power supply module (not shown)；The power supply mould
Block when the monitoring camera amplifies visual field middle section, make two layers described in indium oxide tin film 3124,3125 power down,
Remaining time powers to two layers of indium oxide tin film 3124,3125.
Above-mentioned adjustable night vision monitoring camera preferably makes the surface of each layer indium oxide tin film 3124,3125 everywhere
Uneven thickness or tin indium oxide film surface are covered with hole；Non-uniform orientation electric field can be formed in regulating course 312 as a result, is made
The silver ion of transparent lamina inner surface must be attached in variegated shape, to further increase the degree of disorder to infrared light reflection.
In addition, the power supply module is to the indium oxide tin film 3124,3125 output pulsation direct currents, so that two layers of oxidation
The fluctuation electric field of orientation is formed between indium tin film 3124,3125, to keep the silver ion for being attached to transparent lamina inner surface continuous
Vibration, equally, further increases the degree of disorder of the reflection to infrared light.The power supply module can also be made to make the indium oxide
Before tin film 3124,3125 power down, a backward voltage first is provided to indium oxide tin film 3124,3125 described in two layers, so that attached
In the silver ion fast-falling of transparent lamina inner surface, make the regulating course 312 that transparence quickly be presented.
Above-mentioned adjustable night vision monitoring camera in normal monitoring, the indium oxide tin film 3124 as described in two layers,
3125 are in energized state, and orientation electric field, the silver ion analysis in the silver ion solution for keeping it internal are formed in the regulating course 312
Out, and it is attached to wherein layer of transparent coating inner surface, the uniformity and stability being precipitated due to silver ion are poor, in thin transparent
The mirror surface formed on layer is more coarse, therefore forms that the degree of disorder is higher, is similar to irreflexive reflection to infrared light, optical path signal
As shown in Fig. 2, forming broader infrared light in front of camera lens 2 to make the light-gathering of each infrared generator 3 be in reduced levels
Light filling range, to obtain the biggish night vision visual field；And when the monitoring camera amplifies operation to visual field middle section, two
Indium oxide tin film 3124,3125 power down described in layer, the electric field in the regulating course 312 disappears at this time, and silver ion is detached from transparent
Coating inner surface makes the transparent state of regulating course, at this point, as shown in figure 3, by 312 rear of regulating course by curved mirror structure
At base 311 infrared light is reflected, greatly improve the directionality of reflected light, concentrate in the visual field of the camera lens 2
Centre, thus when amplifying visual field middle section, clarity with higher.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
