The recording apparatus 10 includes a microcomputer for controlling overall functions, a central processing unit (CPU), a camera 12 and a storage medium for storing recording data input through a microphone, A WiFi module for wirelessly transmitting the broadcast signal to the wireless terminal 30, and a GPS receiver for recognizing the location of the recorder 10 and the recording time.

It is preferable that the recording data stored in the storage medium is divided and stored in units of a preset time or capacity so as to be easily transmitted to the server PC 30 in the future. This is because the recording data is stored as a 30-frame file of high definition (HD), which may cause the recording data to be entirely damaged in an unexpected error situation due to a large storage capacity.

Next, the charging cradle 20 is an accessory device for the user to temporarily store or charge the recording apparatus 10, such as a patrol vehicle, a police box, or the like. The cradle 20 is provided with a second contact terminal 21 that contacts the first contact terminal when the recorder 10 is mounted and a power input terminal (Not shown), and a network connection terminal (not shown) connected to the server PC 30 in a wired manner. The front surface of the cradle 20 displays a file transfer status, a charging status, and the like The LED signal lamp 22 is provided.

3, the cradle 20 may include a multi-cradle device capable of charging a plurality of recorders 10 at the same time or simultaneously transmitting recording data from the plurality of recorders 10 to the server PC 30 It is possible.

Lastly, the server PC 30 is provided with a wireless LAN transceiver unit for communicating with a Wi-Fi module installed in the recorder 10, a hard disk for storing recording data transmitted from the recorder 10, And a data management program. The recording data may be transmitted wirelessly through a Wi-Fi module installed in the recorder 10 or may be transmitted through a network installed in the cradle 20 by wire.

In the recording data downloaded to the server PC 30, the location of the recording site, the recording time, and the name of the user are recorded together by the GPS receiver installed in the recorder 10. The recording data is edited and classified in a predetermined format by a data management program installed in the server PC 30. Therefore, necessary evidence can be easily searched by using the name or the date of the user who photographed the recording data later.

The server PC 30 also has a program in a utility data server on the Internet, and a plurality of PCs or mobile phones having usage rights can access the recorded data through a cloud service ).

The present invention is characterized in that first and second Bluetooth modules for recognizing each other are installed in the recorder 10 and the cradle 20 so that pairing between the first Bluetooth and the second Bluetooth, The recording data stored in the recorder 10 is automatically downloaded to the server PC 30 while the Wi-Fi module installed in the recorder 10 operates.

The cradle 20 is connected to the server PC 30 by a network connection terminal (not shown) so that when the recording apparatus 10 is mounted on the cradle 20, It is possible to download the recording data to the server PC 30. [

In the recording system of the present invention, when the recorder 10 and the cradle 20 are distant from each other, that is, while the user wears the recorder 10 and performs a mission, The recording medium 16 is not operated and the recording data is once stored in a storage medium such as an SD card (Secure Digital card) provided in the recorder 10. This is because much power is consumed when the recorder 10 wirelessly transmits the recording data in real time.

When the pair of the first bluetooth and the second Bluetooth accesses the recording device 10 and the cradle 20 within a predetermined distance, for example, within 10 meters, the WiFi module 18 is activated immediately, (30). As described above, in the verification system according to the present invention, when the user returns to the patrol vehicle or the police box where the cradle 20 is provided after completion of the mission, the recording data is automatically downloaded to the server PC 30 The user can not arbitrarily delete or modulate the recorded data.

Another feature of the present invention is that a gravity sensor is additionally provided in the recorder 10. When the recorder 10 is set upright and the X-axis is set in the vertical direction, the Y-axis is set in the front-rear direction, and the Z-axis is set in the left and right direction, Detects movement and impact in the Z-axis direction.

Therefore, when the recorder 10 is in the recording standby state, the microcomputer and the central processing unit (CPU) are activated together with the gravity sensor. In this state, the microcomputer and the central processing unit (CPU) are activated in the X axis, Y axis, If no motion is detected during the time, the central processing unit is down and switched to a sleep mode in which only the gravity sensor and the microcomputer are active. When the predetermined motion is generated in the X-axis, the Y-axis, or the Z-axis direction in the sleep mode, the gravity sensor detects the movement and activates the central processing unit (CPU) again to switch to the recording standby state.

When the predetermined shock is transmitted to the recorder 10 at a predetermined interval in the recording standby state or the sleep mode state, the gravity sensor senses the impact and starts recording immediately. For example, when the impact of the gravity acceleration 2G or more in the Y axis direction is repeated twice or more at intervals of 0.5 to 1.0 second with respect to the recorder 10, the gravity sensor senses the impact and starts recording immediately. Also, if the same impact is detected during recording, recording may be stopped and the recording standby state may be switched.

If such a function is used, the recording apparatus 10 is normally placed in a recording standby state in which power consumption is low, and when urgent recording is required or when it is necessary to prevent the other party from recognizing the recording fact, (10) can be performed only by tapping lightly with a hand, so that the life of the battery can be greatly extended and the use is convenient.

In another aspect of the present invention, the gravity sensor detects the gravity sensor when the recorder 10 is tilted by a predetermined angle in the left and right direction during recording, and inverts the vertical position of the recorded image Function. Since the recorder 10 itself performs recording while the user is performing another activity while being attached to the user's body or clothes, the recording is progressed in a state where the angle of the recorder 10 is skewed during recording. Thus, for example, if the X-axis of the recorder 10 is tilted by 90 degrees or more in the left-right direction and recording is performed for 3 seconds or more, the gravity sensor senses this and reverses the vertical position of the recorded image, So that it can be secured.

While the present invention has been described in detail with reference to the preferred embodiments thereof, the scope of protection of the present invention is not limited by these embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the present invention. Accordingly, the scope of protection of the present invention should be understood by the technical idea of the appended claims.
