Description

Description CAMERA DEVICE WITH VACUUM TUBE

Technical Field

[1] The present invention relates to a camera device with a vacuum tube; and, more particularly, to a camera device using a vacuum tube capable of being used for a fixed outdoor surveillance camera and a camera module supported by the vacuum tube and a supporting member inside of the vacuum tube. Background Art

[2] A surveillance camera(CCTV; closed-circuit television) is classified into an indoor type and an outdoor type according to an emplacement, a rotational type and a fixed type according to whether the direction of a camera can be controlled, and a box type and a dome type according to a shape.

[3] Although the dome type camera is cheap since a lens and a camera are built as one body, but it is almost impossible to be used for an outdoor usage as a waterproof is not treated nor it is adaptable for long distance usage.

[4] For an outdoor surveillance camera, a box type camera is generally used. As a lens is separated from camera in a box type camera, it is needed to additionally purchase a lens according to a usage. Furthermore, a housing for protecting the camera by waterproof, vibration proof, deicing, and screening ultraviolet ray and a bracket for supporting the mentioned items are needed. And, in case of rotational type, a pan-tilt driver for rotating the direction of the camera is additionally needed. This kind of configuration makes a surveillance camera expensive.

The camera device with a vacuum tube in accordance with the present invention is a surveillance camera for observing in a fixed direction, made for outdoor usage, simple and inexpensive, and can be protected from external humidity, dust, rain or snow, and a sun s ray.

[15] And also, while the present invention has been described with respect to certain preferred embodiments, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.

[16]

[17] The above and other objects and features of the present invention will become apparent from the following description of the preferred embodiments given in conjunction with the accompanying drawings, in which:

[18] Fig. 1 is a perspective view of a camera device with a vacuum tube in accordance with the present invention;

[19] Fig. 2 is a front side view of a camera device with a vacuum tube in accordance with the present invention; and

[20] Fig. 3 is a top view of a camera device with a vacuum tube in accordance with the present invention.

[21]

Mode for the Invention

[22] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[23] Fig. 1 is a perspective view of a camera device with a vacuum tube in accordance with the present invention, Fig. 2 is a front side view of the camera device with a vacuum tube and Fig. 3 is a top view of the camera device with a vacuum tube.

[24] A camera device with a vacuum tube in accordance with the present invention 1 includes a vacuum tube 11, a camera module 12 inside of the vacuum tube 11, a supporting member 13 for supporting the camera module 12 inside of the vacuum tube 11, pins 15 installed at a lower part of the vacuum tube 11 to be connected with a socket 14, a wiring 16 for connecting the camera module 12 and the pins 15, a heating element (not shown) inside of the vacuum tube 11, and a temperature sensor (not shown) for measuring temperature inside of the vacuum tube 11.

[25] The vacuum tube 11 is made for protecting the camera module 12 from humidity and dust in the air and for making the camera module 12 do not change in proportion to a temperature change of external air. The vacuum tube 11 is made from a transparent material such as glass and as illustrated in Fig. 1 and Fig. 3, made into a cylindrical shape which is simple in structure and is strong from the external impact. However, the front surface of the camera module 12 is made into a planar shape in order to reduce the effect by the refraction of a wall of the vacuum tube 11.

[26] As shown in Fig. 1 and Fig. 2, the upper part of the vacuum tube 11 is made inclined in order to reduce chances that the vacuum tube collapses due to the stag of raindrops or snow. A semi-spherical shape with a projected center is desirable. And, the upper part of the vacuum tube 11 is treated with a coat 17 which reflects sunlight in order to protect the camera module 12 from sun ray such as ultraviolet rays.

[27] A camera module 12 is fixed and arranged inside of the vacuum tube 11. In case of the camera module 12, it is desirable to use an inexpensive small camera module with a built-in lens, the same with the camera module which is used in a mobile phone in order to reduce production cost. The camera module 12 is protected from humidity, dust, rain or snow, ultraviolet rays and extremely hot or cold whether by the vacuum tube 11 coated on the upper part for preventing the sunlight. [28] The camera module 12 is supported to the vacuum tube 11 by a supporting member

13. The supporting member 13 is prepared in multiple in order to fix the camera module 12. When the temperature of external air is low, it is desirable that the supporting member 13 is made with insulating material such as asbestos as the performance of the camera module 12 can be deteriorated due to low temperature for the camera module which is connected to the vacuum tube 11 and the supporting member 13 which are in contact with external air. And, it is desirable to locate a heating object for raising temperature inside of the vacuum tube 11 in case that the temperature inside of the vacuum tube gets lowered. And, it is desirable to install a temperature sensor for measuring the temperature inside of the vacuum tube. The heating object and the temperature can be fixed on the camera module 12, on the supporting member 13 or on the inside wall of the vacuum tube 11.

[29] The camera device 1 with the vacuum tube is installed on a socket 14. A pin 15 is formed on the lower part of vacuum tube 11, and the pin 15 and the socket 14 are coupled to fix the camera device 1 and are connected to the outside of the camera device. The socket 14 is located on the supporting member 13 which is capable of supporting the camera device 1 with a vacuum tube fixed, and is connected with a device for supplying power and a device for on/off line communication with remote places. The pin 15 and the camera module 12 are connected through a wiring 16. Through the socket 14, the pin 15 and the wiring 16, power is supplied into the camera module 12, a control signal of the camera module 12 is inputted and a picture taken by the camera module 12 is outputted to the outside. And, the wiring 16 is connected to the heating object to supply power and is capable of controlling the heating object.

[30] A short circuit can occur when a raindrop permeates between the socket 14 and the pin 15. So, in order to prevent a raindrop from permeating between the lower part of the vacuum tube 11 and the socket 14, the lower part of the vacuum tube 11 has a protrusion 18 which encompasses the circumference of the socket 14 for preventing a short circuit. The protrusion 18 is further extended lower than the lower part of the vacuum tube 11 from the side of the vacuum tube 11 and the inner circumference of the protrusion 18 is made to the same with or a little bit longer than the circumference of the socket 14 so that raindrops or snow which are fell on the vacuum tube 11 of the camera device 1 can be prevented from permeating into the space between the vacuum tube and the socket and is made to slip down.
