Currently, the parking lots and streets of megacities are filled with a huge amount of vehicles, as a result, car owners are faced with a serious problem - how to park? Very often you have to literally squeeze between standing cars, poles and fences. In this case, literally every centimeter of free space is important. And in order to prevent damage (accidents, scratches, etc.) of the car, the driver needs a device that would assist in difficult situations. One of these "assistants" is a rearview camera with parking sensors.
Device description
Parktronic with a rear-view camera is a system consisting of sensors (from 2 to 8) that receive and emit special wave signals. The device calculates the time of wave return, so that the distance separating the car from the obstacle is calculated. On large vehicles, it is recommended to install the maximum number of sensors, which increases the protection of the car when parking and driving. The rear-view camera in the frame of the car number provides visual information for the driver about what is behind the car (borders, poles, stones, etc.). The use of such a system not only helps when parking in reverse, bypassing narrow and dangerous places, but also can reduce the number of accidents on the highway.
Disadvantages of parking sensors
In difficult weather conditions, when dirt, snow, ice, etc. adhere to the car, the sensors of the device become almost useless. The device is not able to calculate the distance to the obstacle, we can say that it completely "blinds." Therefore, the driver needs to constantly monitor the cleanliness of the remote units. A rear view camera with parking sensors is also sensitive to weather conditions. The lens of the device in wet weather can not only get dirty, but also fog up. Therefore, it is necessary to constantly check its cleanliness and put it in order in time. The second drawback of this system is its sensitivity to the slope of the asphalt pavement, since this parameter distorts the obtained measurement results. The next factor affecting the performance of the device are objects made of materials that can absorb transmitted waves. If such an object comes into the view of the parking sensors system, then it completely loses functionality.
Specifications
The rear view camera with parking sensors provides a night vision function (infrared illumination). It is installed in the license plate frame, on the rear shelf or under the luggage compartment lid. The viewing angle of the camcorder can be from 100 to 170 degrees. The resolution of the matrix is 628 * 582 pixels. The camcorder has a waterproof housing. The operating voltage of the device is 10-15 V,
rated power - 3-6 watts. Such a system is capable of operating at an ambient temperature of -20 to +80 degrees Celsius. Type of sensors - ultrasonic.
Parktronic rear view camera: device features
The device monitor displays information about the distance to the obstacle. Sound beeper gives out intense sound impulses when approaching an object. The image from the camera appears on the screen when reverse gear is engaged. A video device can be either black and white or color. An important parameter of the camera is the ability to transmit a mirror image.
