The monitoring server 220 monitors and displays the images of the surveillance cameras 110 and 120 installed in the field and photographs the surveillance area in real time and analyzes the displayed images to determine whether an intruder appears, It is determined whether an emergency situation has occurred.

When the emergency server 240 is found to be in a state of emergency in the monitoring server 220, the emergency propagation server 240 transmits an emergency call to the relationship between a building manager, a police station, a fire station, a local government, By spreading the situation, we can quickly cope with emergencies.

The management server 260 sets information about a schedule such as when the system will perform surveillance tasks such as illegal parking regulation and security monitoring, sets a criterion for judging whether or not the surveillance work is illegal, 220 to utilize it and check whether the normal operation of the DB 230, the monitoring server 220, the emergency propagation server 250, the overload state, the storage capacity, etc., .

3 is a perspective view and an exploded perspective view of the surveillance camera, particularly the fixed camera 110. As shown in FIG.

3, the surveillance camera includes a housing 10, a lens module 20, a bracket unit 30, an infrared LED module 60, a front cap 91, a rear cap 95, And the like.

The housing 10 has a cylindrical shape and a receiving portion 13 for receiving the lens module 20 and the bracket unit 30 and the like is formed on the inner side so that the front of the receiving portion 13 is opened have.

The first rotating guide hole 11 for guiding the rotation of the levers 31 and 32 and the second rotating guide hole 11 for guiding the rotation of the levers 31 and 32 are provided in the rear of the housing 10, A rotation guide hole 12 is formed.

The wing plate 80 is coupled to the outer periphery of the housing 10 and covers a part of the front cap 91 coupled to the front to block external light from being irradiated to the front cap 91.

The infrared LED module 60 irradiates the infrared rays in the photographing direction of the lens module 20 so that the images are captured more brightly and clearly even in a dark environment.

The infrared LED module 60 includes a PCB 61 having a hollow 62 into which the upper outer circumference of the lens module 20 is inserted and a plurality of LEDs 63 mounted on the PCB and emitting infrared rays .

The bracket unit 30 is installed in the housing 10 with the lens module 20 mounted thereon and operates the levers 31 and 32 exposed to the rear of the housing to adjust the focal length of the lens module 20 do.

The front cap 91 and the rear cap 95 are formed in the outer periphery of the front and rear sides of the housing 10 so that the front cap 91 and the rear cap 95 are screw- Outer packings 92 and 96 are inserted into the front and rear outer peripheries of the housing 10, respectively, to prevent water from flowing into the clearance.

The front cap 91 (in particular, the front surface) is made of a transparent material so that the lens module 20 captures an image and infrared rays emitted from the infrared LED module 60 can be transmitted.

In order to completely seal the gap between the housing 10 and the front cap 91 in which the lens module 20 and the infrared LED module 60 are disposed adjacent to each other to prevent moisture and foreign matter from penetrating, And the outer gaps of the front cap 91 seal the outer packings 92 and 96 and the inner gaps seal the inner packing 41.

A seating groove (42) is formed in the front of the housing (10) so that the inner packing (41) is seated. The inner packing 41 is shaped like a "U" so as to resist being pushed backward in the seat groove 42, and prevents deformation such as wrinkles caused by external force.

The pressure plate 43 is inserted into the inside packing 41 of the U shape and the pressure plate 43 penetrates into the inside of the front cap 91 and the inside packing 41 are protruded from the outer circumferential surface of the protruding portion.

The pressure plate 43 has an opening ring structure capable of expanding in diameter. The expanding portion 45 has a tilted structure that can push the pressure plate 43 to expand its diameter, Elasticity.

The inner packing 41 is seated in the seating groove 42 of the housing 10 and the front cap 91 is moved forward of the housing 10 in a state where the pressure plate 43 is inserted into the inner packing 41 The expansion portion 45 penetrates into the pressure plate 43 and presses the inner surface of the pressure plate 43 to expand the diameter. The pressing plate 43 whose diameter is expanded pressurizes the inner surface of the inner packing 41 to seal the inside clearance between the housing 10 and the front cap 91.

4, the electric signboard 130 includes a sign board 131 for displaying information such as characters and a frame 133 having a square frame structure for holding the periphery of the sign board 131 .

The profiles 135 constituting the frame 133 are fastened to the corner fastener 136.

The corner fastener 136 has a shape of 'a', and has a fitting portion 136a which is inserted into and engaged with the end of the profile 135 on both sides.

At this time, since the profiles 135 are cut into oblique lines at both ends in order to be joined in a rectangular shape, fine coupling gaps may occur between the ends of the respective profiles 135 due to processing errors and the like.

Such a clearance may cause light from the sign board 131 to leak out, and rainwater or the like may penetrate into the clearance to cause failure or malfunction of the sign board 131.

Accordingly, it is possible to prevent the coupling gap from being generated at the corner of the frame 133 regardless of the machining error of each profile 135, to perfectly fill the coupling gap between the profiles 135, To prevent that,

The corner fastener 136 includes a guide groove 136b formed in the longitudinal direction of one of the fitting portions 136a and a shaft member 137 slidingly connected to the guide groove 136b, The shaft 135 and the shaft 135 are coupled to each other so that they can be pivoted in the left and right direction and are moved to the corner of the corner fastener 136 together with the shaft member 137 when the profile 135 is engaged, And a sealing pad 138.

The guide groove 136b is a groove formed in the front surface (or rear surface) of one of the fitting portions 136a to guide the movement of the shaft member 137 and the sealing pad 138. [

The shaft member 137 is engaged with the guide groove 136b and is movable along the longitudinal direction of the guide groove 136b. When the shaft 135 is engaged, the shaft member 137 is engaged with the corner fastener 136 And serves as an axis which becomes the center of the left and right rotation of the sealing pad 138. [

The sealing pad 138 is formed in a bag shape of a flexible material having a predetermined elastic force so as to provide airtightness by filling a clearance between the profiles 135. The airtight space is filled with air An air cell 138a is formed.

Even if the positions and angles at which the end portions of the respective profiles 135 are brought into contact with each other due to the machining error occurring when the ends of the profiles 135 are sliced are changed by using the corner fastener 136 having such a structure, The pad 138 is moved and rotated to the corner of the corner fastener 136 so that the sealing pad 138 is fixed at the correct position and angle to fill the gap between the profiles 135.

Also, since the sealing pad 138 is pressed inward when the both side profiles 135 are engaged, the air inside the air cell 138a is expanded while being pushed to the edge to cover the coupling gap between the profiles 135, At this time, the sealing pad 138 expands in the defect gap to completely seal the coupling gap, thereby securing the airtightness.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it should be understood that various changes and modifications may be made therein without departing from the scope of the invention as defined by the appended claims. Should be interpreted as belonging to the scope.
