The present invention relates to a CCTV camera device having a function of removing foreign matter and preventing condensation of a housing. More particularly, the present invention relates to a CCTV camera device having a foreign matter detection sensor for detecting foreign matter adhering to a protective film such as glass in front of a camera lens, and a control unit for operating a wiper And a device for removing foreign materials on the front part of the CCTV camera that automatically removes foreign substances by operating a wiper when a predetermined amount or more of foreign substances adhere to the protective film, and at the same time, various devices are provided so as to maintain the warming in winter. And a control method of the CCTV camera device.

A television (TV) system for providing a user with an image photographed at another place is classified into a closed circuit system and an open circuit system. The latter is to transmit image information to an unspecified number of users This is the purpose, usually the TV broadcast we are talking about.

An electronic closed loop system, on the other hand, refers to a system that delivers image information to a specific user for a specific purpose and is referred to as CCTV (closed circuit television).

CCTV is a closed-circuit television system that connects the transmission and reception of video images either wired or wirelessly. It is called a closed-circuit television system and can be used for industrial, educational, medical, indoor security, traffic control monitoring, And for image information transmission.

The constituent elements of the present invention mainly include a camera housing 1, a wiper 2, an ultrasonic sensor 3, a cover glass 4, a heat insulating box body 10, a lens structure 20, And a camera 30.

The camera housing (1) has a rectangular parallelepiped shape and is constructed as an assembled type.

The wiper 2 is installed on the front surface of the camera housing and operates when rainwater or dust such as yellow dust is present.

The ultrasonic sensor 3 is a sensor for detecting whether rainwater exists or dust exists on the front end of the camera housing. In other words, the ultrasonic wave is output to judge the presence of rainwater or foreign matter by determining the return distance. If rainwater or foreign matter exists, a short distance is checked. If there is no rainwater or foreign matter, a long distance is checked. The foreign object is present in the camera housing, so that the wiper is operated.

The cover glass 4 is installed on the front surface of the camera housing. If there is a rain, the cover glass 4 is dusty if there is a lot of dust and is read by an ultrasonic sensor and wiped by a wiper.

The heat-insulating box body 10 is installed inside the camera housing and functions to maintain the thermal insulation of the camera housing.

The lens structure 20 is installed inside the camera housing and is installed on the back side of the cover glass and serves to receive light from outside the camera housing.

The camera 30 is installed inside the camera housing, and is installed at the rear part of the lens structure, and shoots light input through the lens structure.

In addition, the present invention can be applied to an air conditioner in which the compression insulation material 40, the sponge 50, the first conductive film 60, the second conductive film 70, the air injection hose 80, , A compressor (100), and a control unit (110).

The compression heat insulating material (40) is installed inside the heat insulating box body (10) and functions as a heat insulating and condensation preventing function.

Since the sponge 50 is disposed between the compression insulation material 40 and the heat retaining box body 10 and is expandable due to the nature of the sponge 50, the sponge 50 is extended to the convex portion of the heat retaining box body 10, Lt; / RTI >

The first conductive film 60 is attached to the sponge 50 and includes a first coil part 61 and a first electrode part 62. When electricity is applied to the coil through the electrode part 62, .

The second conductive film 70 is disposed inside the convex portion 10a of the heat-retaining box body 10 and is provided corresponding to the first conductive film and includes a second coil portion and a second electrode portion, Electricity is applied to the coil to separate the first conductive film 60 and form a space portion.

The air injection hose 80 is inserted between the first conductive film 60 and the second conductive film 70 and is provided with air in the space between the first conductive film 60 and the second conductive film 70 Thereby inducing the condensation phenomenon to be prevented.

The outside air temperature sensor 90 senses a temperature outside the camera housing and checks a temperature condition below a certain level.

The compressor 100 serves to supply air through the air inlet hose 80.

The controller 110 receives data from the ambient temperature sensor 90 and supplies electricity to the first conductive film 60 and the second conductive film 70 when the temperature is lower than a predetermined temperature so that a space is formed between the first conductive film 60 and the second conductive film 70 And air is supplied through the air discharge hole 81 of the air supply hose 80 provided in the space portion to prevent the condensation phenomenon from occurring inside the heat preservation box body 10 in advance.

Hereinafter, the overall operation of the present invention will be described.

First, the present invention places the compression insulation material 40, the sponge 50, the first conductive film 60, the air injection hose 80, and the second conductive film 70 in sequence. The outside temperature sensor 90 and the compressor 100 are installed outside the camera housing 1.

Since the sponge 50 is installed just inside the heat-insulating box body 10, the sponge 50 is entirely accommodated in the bent portion. However, since the convex portion 10a has a low density, it is difficult to avoid the occurrence of the condensation phenomenon.

The present invention is characterized in that the box body 10 for keeping warming is provided in the camera housing 1 and the condensation preventing means is separately provided in the convex portion of the heat retaining box body 10 to prevent condensation Thereby preventing condensation from occurring inside the camera housing.

For example, when the control unit 110 receives outdoor air temperature data from the outdoor air temperature sensor 90, it determines that there is a possibility of condensation if the reference temperature is 0 degree and the current temperature is 0 degree or less.

That is, when the outside air temperature is 0 degree or less, electricity is supplied to the first coil portion 61 and the second coil portion 71 so that the first conductive film 60 and the second conductive film 70 mutually repel The space portion is enlarged.

At this time, the compressor 100 is operated to supply air to the air injection hose 80 provided in the space portion so that air flows between the first conductive film 60 and the second conductive film 70, It is possible to prevent a condensation phenomenon from occurring in the housing 1 beforehand.

Since the first conductive film 60 is provided on the sponge 50, when the electricity is supplied, the sponge 50 is easily pushed back and the space is enlarged between the first conductive film 60 and the second conductive film 70.

If the dew condensation preventing means composed of the first conductive film 60 and the second conductive film 70 is not added, the density of the sponge 50 provided inside the heat keeping box body 10 is low Condensation may occur and dew may be generated and water may flow severely. However, according to the present invention, space can be secured in the convex portion 10a, air can be injected, and outside air can be injected, thereby preventing condensation from occurring.

That is, since the air supplied through the compressor (100) and the air supply hose (80) induces a flow of convection inside the camera housing, it is possible to fundamentally block the condensation caused by the temperature difference between the inside and the outside of the camera housing .
