[0002] With the development of society, cameras, which upload and backup the captured video signals, have gradually become a means of monitoring and evidence collection and are constantly evolving.

[0020] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation modes.

[0021] Embodiment 1

[0022] Refer to Figure 1 and Figure 2 , which shows a schematic structural diagram of a high-definition camera of the present utility model, specifically including: a control board 1 and a three-way camera 2; the three-way camera 2 includes: a three-way housing 21 and a lens module 22; the three-way housing 21 is a cylinder with three azimuth planes adjacent to each other; the lens module 22 is respectively embedded on the three azimuth planes of the three-way housing 21; each lens module 22 is electrically connected to the control board 1.

[0023] It should be noted that the high-definition camera is often used to monitor a certain area. The light source in this area is captured by the lens module 22, and then imaged on the image sensor 23 and the video signal is output to the control board 1. The control board 1 uploads this signal to the background for the user to observe.

[0024] It should also be added that as Figure 3 shown, the three-way camera 2 is composed of three lens modules 22 in three directions, that is, three identical lens modules 22 that jointly shoot and form an all-round view through the control board 1. One lens module 22 monitors one plane, that is, 120°, and three lens modules 22 monitor three planes, and can simultaneously monitor a 360° picture. Even if there is still a monitoring blind area at this time, the blind area is directly below the high-definition camera. However, since the blind area is within the monitoring range, if you want to reach the monitoring blind area, you must first pass through the monitoring range, and you will be tagged by the control board 1 within the monitoring range, so as to achieve 360° monitoring.

[0028] Furthermore, the high-definition camera is further provided with an LED lamp board. The LED lamp board includes LED lamp beads 1 to LED lamp beads 9, resistors R1 to R9, a zener diode ZD1, a voltage regulator chip TL431, a capacitor C1, a photoresistor RU1, and a triode Q1. Among them, LED lamp beads 1 to LED lamp beads 9 form a 3*3 lamp bead array. After three lamp beads are connected in series to form a series section, and then three such series sections are connected in parallel to form the lamp bead array. Among them, resistors R7, R8, and R9 are respectively arranged in the three series sections. The lamp bead array is connected to the collector of the triode Q1. The emitter of the triode Q1 is connected to the DC12V power supply. The base of the triode Q1 is connected to the DC12V power supply after being sequentially connected to the resistor R5 and the resistor R2. The DC12V power supply is simultaneously grounded after passing through the resistor R1, the resistor R3, and the photoresistor RU1 in sequence. The capacitor C1 and the zener diode ZD1 are respectively connected in parallel outside the resistor R3 and the photoresistor RU1.

The middle connection point of the resistor R3 and the photoresistor RU1 is connected to the reference pole of the voltage regulator chip TL431. The cathode of the voltage regulator chip TL431 is connected to the middle connection point of the resistor R2 and the resistor R5. The anode of the voltage regulator chip TL431 is grounded. A resistor R6 is connected between the anode of the voltage regulator chip TL431 and the lamp bead array.

[0029] Embodiment 3

[0030] Refer to Figure 5, showing a schematic structural diagram of a lens module of an embodiment of a high-definition camera of the present utility model. The lens module 22 includes: a lens barrel 221, a first lens 222, a second lens 223, a third lens 224, and a fourth lens 225; the first lens 221, the second lens 222, the third lens 224, and the fourth lens 225 are sequentially arranged along a straight line in the lens barrel 221; the lens barrel 221 is arranged at preset positions on three azimuth planes of the three-phase housing 2.

[0031] As a preferred embodiment, a first limiting groove for accommodating the first lens 222 is formed in the inner wall of the lens barrel 221. A first fixing ring is arranged between the first lens 222 and the second lens 223, a second fixing ring is arranged between the second lens 223 and the third lens 224, a positioning ring is arranged between the third lens 224 and the fourth lens 225, and a second limiting groove for accommodating the fourth lens 225 is further arranged on the inner wall of the lens barrel 221; the first lens 222 includes a first plane arranged on the side far from the second lens 223 and a first concave surface arranged on the side close to the second lens 223; the second lens 223 includes a first convex surface arranged on the side close to the first lens 222 and a second convex surface arranged on the side close to the third lens 224; the third lens 224 includes a second concave surface arranged on the side close to the second lens 222 and a third convex surface arranged on the side close to the fourth lens 225; the fourth lens 225 is a plano-convex lens. By arranging four lenses in the lens barrel 221 and specially setting the four lenses, the present utility model can refract light, reduce the degree of imaging distortion, and further improve the recognition degree of imaging.

[0032] Further, the first fixing ring is provided with a light-transmitting hole, and the diameter of the light-transmitting hole gradually decreases from the first lens 222 to the direction of the second lens 223; the edge of the first concave surface is circular, the diameter of the light-transmitting hole at the end close to the first lens 222 is greater than the diameter of the edge of the first concave surface, and the diameter of the light-transmitting hole at the end far from the first lens 222 is less than the diameter of the edge of the first concave surface. The first fixing ring can, on the one hand, improve the stability of the first lens 222 and the second lens 223, and on the other hand, ensure that the light refracted by the first lens 222 can fully enter the second lens 223, reducing the degree of imaging distortion.

[0033] Furthermore, in order to protect the first lens 222, one end of the lens barrel 221 close to the first lens 222 is detachably connected with an end cap, and the end cap is provided with a protective lens. Specifically, the lens barrel 221 and the end cap are threadedly connected.

[0034] More preferably, the outer diameter of the end cap is greater than the outer diameter of the lens barrel 221, which facilitates the installation of the lens barrel 221 onto other devices.
