Abstract

The present invention relates to an ultra-small television which can connect up to four surveillance cameras.
In the present invention, by using a storage medium of a small size, in addition to reducing the size fundamentally, while connecting up to four cameras, while inventing an automatic frame sharing method that does not compromise the quality of the screen at all, it is intended to apply at least the size of the circuit board In order to do this, the search function is eliminated as the DVD itself, and only the storage medium is extracted and connected to a general PC so that the search can be performed.
The ultra-small DV can be automatically frame-sharing of the present invention can keep the recording screen clean, even though it is very small, and can be installed anywhere near the camera, using the SD as a storage medium, recording without sound When it is possible to search, there is an advantage that the recording can be continued by exchanging only the storage medium.

Description

COMPACT DIGITAL VIDEO RECORDER WITH AUTOMATIC FRAME SHARING}

The present invention relates to an ultra-small television which can connect up to four surveillance cameras.

The DVR to be used in a moving vehicle that generates strong vibrations during use is a recording storage medium, and it is preferable to use it as an SSD which does not generate any noise and does not rotate the motor at all, rather than the current HDD. Among them, the 1.8 "type is only 50mm × 70mm × 5mm (thickness), so it can make a very small size of the TV.

In the present invention, by using a storage medium of a small size, it is fundamental to reduce the size, but also to apply the automatic frame sharing method that does not damage the quality of the screen even if connecting up to four cameras, and to minimize the size of the circuit board In order to omit the search function as the DVR itself and extract only the storage medium and connect it to a general PC for searching, it is possible to create a miniature jib grain which can be miniaturized.

In the present invention, up to four cameras can be connected to the DV, and when only one camera is connected, the recording proceeds at a speed of 30 fps, and when two cameras are connected, the camera automatically records at a 60 fps speed. 30fps frame sharing is achieved. If 3 cameras are connected, it will be changed to 90fps, and if 4 cameras are connected, it will be changed to 120fps and automatically 30fps per camera. This way, even if four cameras are connected, the screen quality will not degrade at all.

The ultra-small DV can be automatically frame-sharing of the present invention can keep the recording screen clean, even though it is very small, and can be installed anywhere near the camera, using the SD as a storage medium, recording without sound When it is possible to search, only the storage medium is exchanged, the DVR itself has the advantage that can continue recording.

1 is a schematic diagram of an ultra-small television with which up to four cameras can be connected.

Frame sharing allows the following recordings.

(1) 1 camera, 30 fps

(2) 2 cameras ... 60 fps

(3) 3 cameras ... 90 fps

(5) 4 cameras ... 120 fps

The DVD of the present invention uses SSD, which is resistant to vibrations, so that there is no problem in using it in a vehicle, and searches for recorded contents by pulling out only the storage medium so as to minimize the size of the circuit board. Connect to PC and check.

Claims

In the compact DV which can connect up to 4 surveillance cameras, frame sharing is automatically performed according to the number of cameras so that the screen can be maintained at the same level even if 4 cameras are connected. In addition, the playback function is removed from the inside of the DVR, and the recorded screen can be searched for in a removable storage medium, and only this can be pulled out and connected to a general PC for automatic frame sharing.
