However, the conventional technique is a method of transmitting a photographed image using Wi-Fi, but may be used in an area where a large number of Wi-Fi base stations exist, such as a city center, but in an area where Wi-Fi is not formed or particularly in an underground parking lot. As a result of the vehicle, the Wi-Fi base station changes from time to time, which causes a problem that the video is interrupted.

In addition, there is a conventional technology for wirelessly transmitting an image of a surveillance camera rather than a vehicle camera. Such a technique includes the registered patent 10-1066816, "Wireless transmission and reception dual recording surveillance system."

The prior art Patent Publication No. 10-1066816 "Wireless transmission and reception dual recording surveillance system" is a wireless transmission and reception dual recording surveillance system, using a fixed or movable camera wirelessly intruder or in places where it is difficult to install the camera by wire. The present invention relates to a wireless transmission and reception dual recording surveillance system for observing criminals or preventing accidents. According to the present invention, even if an error occurs in the wireless transmission / reception, the video transmission unit may record in real time even if the image reception unit is not monitored, so that even if an accident occurs in the field at the moment when the wireless transmission / reception is not good, the recorded accident moment image may be viewed later. A wireless transmission / reception dual recording surveillance system can be provided.

In addition, the present invention can provide a wireless transmission and reception dual recording monitoring system capable of recording in the image receiving unit as well as the image transmission unit to perform dual recording for the same image. In addition, the present invention can provide a wireless transmission and reception dual recording surveillance system that can grasp in advance the real-time behavior of the intruder through a monitor installed in a security vehicle using a camera installed in a specific area.

In addition, the present invention proposes a wireless transmission and reception dual recording surveillance system that allows a plurality of users to display the field image acquired and stored by the camera at a remote location using WiBro and wired and wireless Internet.

However, the conventional technology is that the storage module is added to the transceiver as it is configured to record directly from the wireless transmission and reception device, which is inevitably increased in size and is not suitable to be installed in the rear camera of the vehicle black box. there is a problem.

Therefore, the present invention has been made to solve the above problems, in the multi-channel vehicle black box capable of wireless communication,

The internal structure of each recording unit is simpler than the method of embedding a transmission / reception module in the front and rear photographing units of the black box, so that the front and rear photographing units can be miniaturized.

It is easy to install and maintain because the wireless transmitter and receiver are not provided with a connecting cable for interconnecting each recording unit through a male and female connector that can be attached and detached to each recording unit.

It is easy to adjust the photographing angle of the rear photographing unit by combining the rear photographing unit with the hinge part of the main body.

Forming the engaging projection on the main body of the rear photographing unit, by coupling the rotary ring to the engaging projection to facilitate the hinge coupling of the mounting portion,

It is an object of the present invention to provide a multi-channel vehicle black box capable of wireless communication with increased durability by preventing the rotation ring from being separated from the coupling protrusion by providing a separation prevention protrusion and a separation prevention groove, respectively.

In order to achieve the above object, the multi-channel vehicle black box capable of wireless communication according to the present invention is

A recording unit including a rear photographing unit including a rear camera photographing the rear, a front photographing unit including a front camera photographing the front, and a memory for recording and storing images photographed by the front camera and the rear camera; A wireless communication unit including a transmission module coupled to a unit to wirelessly transmit an image captured by the rear camera, and a reception module coupled to the recording unit to wirelessly receive an image transmitted by the transmission module,

The transmitting module and the receiving module are each provided with a male connector or a female connector detachably connected to a female connector or a male connector provided in the rear photographing unit and the recording unit.

As described above, the multi-channel vehicle black box capable of wireless communication according to the present invention does not use a part of the internal electrical wiring or install a cable connected to the vehicle by combining the male and female connectors so that the transmission and reception module can be detachably attached to the front and rear photographing units. Easy to install and easy to maintain, it can solve the problem of failing to save the accident video by disconnecting the connection cable in case of accident,

Since the transmission module is not configured inside the front and rear photographing unit, the front and rear photographing unit can be miniaturized, and the trouble of disassembling the front and rear photographing unit can be solved when the transceiver module breaks down.

By combining the rear and the rear unit, the mounting unit and the main unit can easily adjust the shooting angle of the rear unit.

Forming the engaging projection on the rear camera, by combining the rotary ring to the engaging projection combined with the rear photographing unit does not use the coupling method such as bolts, the structure is simple and at the same time easy to rotate when combined with the mounting portion by the rotation ring. Let

Each of the rotation ring and the engaging projection is provided with a departure prevention protrusion and a departure prevention groove, respectively, so that even when an external impact such as an accident, the rotation ring is not detached, thereby preventing the rear photographing unit from being separated.
