The video surveillance basically controls the panning and tilting of the CCD camera 110 based on the preset panning and tilting control values, and the CCD camera 110 captures the image of the surveillance area while the panning and tilting is controlled as described above. Done. In addition, the dynamic range 140 adjusts the contrast of an image through the 128 times dynamic range of the surveillance image photographing the surveillance region.

The web server 120 compresses the surveillance image acquired through the CCD camera 110 by a general image compression method, and temporarily stores it in an internal memory. If the surveillance video acquired from the surveillance area is automatically stored on its own, it is possible to monitor the site in real time as needed regardless of the place.

In addition, it is possible to install the mobile image device 100 easily and conveniently by the above functions.

When the web server 120 makes a wireless connection with the remote control system 200 and the transmission of the surveillance image from the control system 200 is requested, the web server 120 transmits the surveillance image stored in the memory to the access point 150. The access point 150 converts the surveillance image into a format suitable for a set wireless transmission method, and then transmits the surveillance image to the control system 200 located remotely through the antenna 160. Here, the access point 150 is operated through web-based management, the frequency range is 1.412 ~ 2.462Mhz band or 2.412 ~ 2.483Mhz band, the wireless output level is 15dBm ~ 2dBm, the channel is 1 ~ 14 Use the channel properly.

In addition to these specifications, all the functions and specifications used in the general broadband wireless signal transmission apparatus are properly performed to perform wireless communication.

The control system 200 receives the surveillance image transmitted wirelessly from the mobile video apparatus 100 through the antenna 21, and the wireless communication unit 220 receives the received signal in the same manner as the access point 150. The process is provided to the control server 230.

The control server 230 transmits the provided surveillance image to the signal processor 250, and the signal processor 250 transmits the surveillance image to the digital video recorder 240 for storage. In addition, the signal processor 250 stores the received surveillance image and simultaneously transmits the surveillance image to the monitor 270 so that the surveillance image of the site is displayed through the monitor 270 in real time. Make sure you know the video. This makes it convenient to monitor the site visually. Here, the image displayed on the monitor is displayed by a progressive output method, so that a moving object can be reproduced smoothly.

While monitoring the image of the site in real time, the manager of the control system 200 wants to make a call with the manager in the field. The voice is sequentially transmitted through the signal processor 250, the control server 230, the wireless communication unit 220, and the antenna 210, and then transmitted to the mobile imaging apparatus 100.

The mobile imaging apparatus 100 transmits the transmitted audio signal to the antenna 160, the access point 150, the web server 120, and processes the signal, and transmits the signal through the speaker 180 to the manager of the field. The voice sent by the administrator is delivered. Similarly, the voice transmitted by the on-site manager is transmitted to the control system 200 in the reverse order as described above, and the control system 200 is also signaled in the reverse order to the voice transmission, and through the site manager through the speaker 260. Voice is sent out.

Through this process, voice call is made possible in real time between the manager of a remote control system and the manager of mobile video equipment on site.

On the other hand, one of the features of the present invention is to remotely control the mobile image device 100 in the field from a remote. That is, the manager of the control system 200 monitors the scene image through the monitor 270, and if necessary, panning / tilting, illumination, and infrared light of the CCD camera 110 through a data input device (for example, a keyboard). A command such as driving is input.

The remote control command is transmitted to the wireless communication unit 220 through the control server 230, the signal is processed through a wireless signal processing method as well known and then wirelessly transmitted to the mobile imaging device 100.

The mobile imaging apparatus 100 receives the transmitted remote control command through the antenna 160, is signaled through the access point 150, and then transmitted to the web server 120. The remote control command is searched for and controls the panning, tilting, illuminance and lighting of the infrared light of the CCD camera accordingly. In addition, remote control of all functions that can be remotely controlled is possible.

In addition, the present invention has the advantage that the low light function, the infrared function is added, it is possible to implement a clear image even in a dark environment such as night.

In particular, the administrator of a remotely located control system can set up a variety of settings while viewing the site image, enabling further optimization of field video surveillance.

As another feature of the present invention, when the signal processor 250 displays an image on the monitor 270, the signal processor 250 may display up to eight still images on one screen, and eight stills displayed on the monitor by the administrator. When a specific image is selected from the images, a control command for moving the CCD camera to a designated position is transmitted to the mobile imaging device. After that, the CCD camera of the mobile imaging apparatus captures the image of the designated position and transmits the image to the control system so that the live image is displayed on the monitor.

In addition, the present invention can generate an alarm signal by itself in the mobile video device 100 when an intruder is detected by the object monitoring unit 190, and in another way to transmit the intruder detection signal to the control system, By generating an alarm signal through the speaker 260 in the control system, the administrator of the remotely located control system can easily identify the intruder.
