It can be secured.

Fourth, in the past, the headlights of the rear vehicle were reflected on the rearview mirror at night, so that the rear situation could not be seen instantaneously due to the glare. However, the present invention uses the rear and rear cameras and the monitor installed in front of the driver. Since the rear view can be confirmed, the rear situation is directly displayed by a monitor inside the vehicle, and thus there is an effect of solving a problem (reflection, glare) caused by the rear light.

fifth. Conventionally, in the case of bad weather such as rainy weather due to water droplets and moisture on the left and right door windows and the rear view mirror, it is difficult to secure the rear view because it is difficult to secure the rear view, the present invention is a monitor installed in front of the rear and rear camera and the driver Since it is possible to check the left and right rear view of the vehicle, even if condensation occurs due to rain, agriculture, temperature difference between the inside and outside of the vehicle, there is no problem in securing the view of the rear and rear side due to bad weather. There is an effect that can resolve the visual disturbances.

Sixth, the left and right rear view of the vehicle can be checked by using a pair of rear and rear cameras and a pair of monitors installed in front of the driver, so that the driver can instantly compare the left and right rear view images in reverse and rear parking. It has the effect of being able to back up and park quickly and accurately while keeping an eye on the monitor without turning the head to the left or right.

Seventh, by recording and playing back and rear images captured by a pair of rear and rear cameras using a DVR, it saves on-the-spot images during driving and parking, and is used as evidence for theft of vehicle damage by others. It can be used to prevent crime and car damage.

Eighth, a separate pair of front cameras capable of photographing the front at the position where the rear and rear cameras are installed, and the image of the front of the vehicle photographed by the front camera can be displayed through a monitor, and the side photographed by the rear rear camera By allowing the driver to select the rear image and the front image captured by the front camera by selecting the channel by the channel selection key, it is possible to know the rear and rear situation simultaneously with the monitor alone. The effect is to inform the front and rear of the situation.

Ninth, the front camera and the rear and rear camera can be identified by the infrared camera at night, which makes it easy to secure the front and rear view even in bad weather and at night, and the front can be easily seen without the headlight. There is an effect that can drive.

Tenth, by realizing the rear and rear cameras as a camera having a zoom in / zoom out function, it is possible to selectively view the distance and the near distance according to the driving situation.

The eleventh, the protective glass of the side rear camera and the front camera to form a UV coating to reduce the intensity of light incident on the side rear camera and the front camera to prevent glare due to strong direct sunlight of the rear driving vehicle.
