Description

Portable surveillance camera {Portable watch camera}

The present invention relates to a portable surveillance camera, and more specifically, it can be controlled in a video manner as well as simultaneous recording when using an auxiliary storage device, and also adopts an infrared LED, which can be used at night, and a built-in dark field function and a zoom function. By using the lens, it is possible to zoom and focus the distant object by simple switch operation to see the clear image, and also has the advantage that it can be applied to security, industrial use, military use, etc. It can be used anywhere and is easy to operate, which greatly improves the quality and quality of the product, allowing consumers to maintain reliability.

As is well known, surveillance cameras are widely used for security surveillance, industrial use, video surveillance of vehicles, traffic management, and so on. These surveillance cameras have been used for the purpose of monitoring something, but with the change of the times, the surveillance cameras are shifting from the surveillance purpose to the safety protection system for the prevention of human and disaster disasters.

Briefly summarizing the above surveillance camera, connecting the camera with a coaxial cable and viewing it as a monitor is called a CCTV (closed circuit) camera, which is used for near field surveillance such as offices, banks and factories around us. By installing and protecting important assets, facilities, and life-savings from unauthorized intruders, the company prevents inadvertent accidents and damages in advance and responds promptly and accurately, while invading prayer, destruction, and other situations. Its purpose is to ensure safety by preventing damages in advance. In addition, infrared cameras are charge-coupled device (CCD) cameras with sufficient sensitivity to infrared rays. When photographing wild animals and plants at night, an infrared filter is attached to a light-intensive light, which is very effective because it does not damage the natural ecosystem. . Recently, near infrared light sources using lasers and integrated infrared cameras using image intensifiers (II) have been tested. In addition, CCD (Charge Coupled Device) is a rectangular direct light emitting diode that receives light and converts it into an electrical signal. Currently, 1/2 inch 1/3 inch 2/3 inch CCD lenses are commonly used. It is written. This CCD converts the intensity of light into the amount of electric charge and converts it into electrons. In other words, the logic is to capture the subject you want to shoot in light and shade and convert it into an electrical signal for storage. Digital cameras use CCDs instead of film. The light passing through the lens passes through the aperture and is transmitted to the CCD instead of the film. This indicates how precisely the image received by the device can be expressed. For example, if a digital camera has a resolution of 3096 X 2048 (approximately 6 million pixels), When the CCD device accepts an image, it expresses the image in 3096 horizontally and 2048 vertically. Therefore, the higher the resolution, the higher the resolution.

However, the surveillance camera has the following problems.

In other words, CCTV was developed for surveillance, but at 0 LUX it was not possible to identify the exact subject, and a certain amount of light must be accompanied for basic power supply to illuminate the available light. There is a problem that the cost increase and the size of the product is large and the maintenance cost is high. In addition, although the CCTV camera is mainly used for theft and crime prevention light, there is a weakness that the main monitoring function is weakened because the monitoring position is easily confirmed due to light radiation at night. In addition, due to the technical limitations of the existing CCTV cameras, the short shooting distance within 6 meters could not be ensured, and therefore, it was not possible to secure the scene of the night surveillance object and the incident. have. To solve this problem, a digital video recorder (DVR: Digital Video Recorder) has been developed. The existing Video Cassette Recorder (VCR) repeats the recording several times, so the picture quality is reduced, and it is troublesome to replace the video tape. Hard disks (HDD) or digital video disks (DVDs) are used instead of video tapes, making it easier to play back and retrieve stored screens, as well as digital signals. Using MPEG-4, which is the standard for video compression, it compresses and saves video screens to about a hundredth and transmits them.It can be searched by camera as well as by time and date. Search, backup and camera control are also available. Products that connect to the Internet and others without wires have also emerged as the next generation security devices. However, DVR, like CCTV, has a problem in that it is necessary to take into consideration that it is expensive equipment due to the cost increase and the size of the product is increased due to ancillary devices.

In addition, the conventional camera has a fixed type, that is, the camera has to be installed at a designated location, as well as security officers and security company employees carry the location directly and securely locate the object and secure the distance between objects. There was also a problem that can not.

Furthermore, since the conventional camera is fixed, there is a problem that it is not possible to secure evidence during various events or events.

The present invention has been made to solve the above-mentioned problems of the prior art, and the first object of the portable surveillance camera is to control the video method as well as to simultaneously record when using the auxiliary storage device, the second object The objective is to use a lens with a built-in dark field function and zoom function that can be used at night by using infrared LED, so that you can zoom and focus far objects with a simple switch operation to see clear images. It has the advantage that it can be applied to security, industrial use, military use, etc.The fourth purpose is the Gun type, which is particularly portable, so that it can be used anywhere and is easy to operate. Has provided a portable surveillance camera that greatly improves the quality and quality of the product so that consumers can maintain their reliability. .

In order to achieve the above object, the present invention is a surveillance camera that protects and protects important assets, facilities, and lifespan from unauthorized intruders, and is provided inside the front end of the body to collect or divert light from an object to obtain an optical image. Condensing lens; An infrared LED provided on an outer circumferential surface of the lens and usable at night; A charge coupled device (CCD) connected to the lens and configured to receive light and convert the light into an electrical signal; A microprocessor connected to the charge coupling device and controlling a system of a portable surveillance camera; A control switch connected to the microprocessor and used to adjust power ON / OFF and LCD ON / OFF, zoom / focus, and menu functions of the camera; An on-screen display (OSD) connected to the microprocessor and directly displaying information required by a user or information to be known on a monitor screen; A motor control connected to the lens and the microprocessor, the motor control controlling an electric motor of the lens to focus at a certain distance and adjust the distance of the lens; It is connected to the motor control, the regulator to maintain a constant voltage at all times; provides a portable surveillance camera characterized in that consisting of.
