Problems solved by technology
[0006] However, the use of dedicated lines also results in high usage fees and low utilization due to the installation of a new line for each monitoring area
[0007] Simultaneously, above each conventional method runs into a problem, and that is exactly when monitoring automatic teller machine (ATM), no matter whether there is user to exist, because the storage of the image data of monitoring or transmission make data amount all can increase
Therefore, the conventional method has the disadvantage of requiring a large capacity of the storage device in order to prolong the recording time in the storage device if necessary
Moreover, the traditional method takes into account the amount of monitored image data and only uses a camera facing forward, so that it is impossible to track and identify users who wear hats or hoods to approach and use ATMs illegally

Embodiment Construction
[0021] A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.
[0022] 1A and 1B are schematic diagrams showing a conventional way of installing an ADSL modem.
[0023] 1A and 1B show that, under the conventional technique, an ADSL modem 12 is installed on the remote terminal 11, the remote terminal is installed on the target facility to be monitored, and an ADSL modem 13 is installed in the central office 14, when it is assumed that from When the remote terminal 11 to the central office 14 is in the upward direction and the opposite direction is the downward direction, the maximum transmission rates of the upward transmission bandwidth and the downward transmission bandwidth are 384 Kbit / s and 8 Mbit / s respectively.
[0024] Therefore, the conventional techno...

Disclosed are a real time remote monitoring system and a method therefore using an ADSL in a reverse direction. The real time remote monitoring system according to the invention includes monitoring unit for monitoring an object facility to be monitored, remotely monitored data processing unit for monitoring motions according to each channel with respect to the monitored data obtained by the monitoring unit, first ADSL modulating / demodulating unit installed in a reverse direction for modulating the data inputted from the remotely monitored data processing unit, second ADSL modulating / demodulating unit installed in a reverse direction for demodulating the data transferred from the first ADSL modulating / demodulating means in a transmission velocity higher than that of the downward channel so as to be transferred to a receiving party, and modulating the data transferred from the receiving party.
Description
technical field [0001] The present invention relates to a remote monitoring system and a remote monitoring method, and more particularly, to such a remote monitoring system and remote monitoring method that can reverse compress / Real-time monitoring by transmitting video / audio data. Background technique [0002] One of the traditional remote monitoring methods is to use a monitoring camera to capture image data for monitoring, and the image data is stored in a dedicated storage device in the corresponding area and used for analysis when an event occurs. However, this method is of low practicability because it does not have the ability to monitor far-end targets in real time. [0003] Another traditional remote monitoring method is to use the Integrated Services Digital Network (ISDN). However, ISDN has a low capacity in transmitting large amounts of data at high speed and in real time, such as transmitting monitoring image data. Therefore, another method used in place of ...
