The car camera is an electronic assistant system for car driving safety. The installation of the car camera can greatly improve the driving safety performance. The car camera has become an indispensable hardware for traffic safety. The quality of the car camera directly affects whether the reversing image is clear and is it easier to be recognized by the owner.
Next, I will introduce you to the common sense and troubleshooting of the car camera.Car camera classification: Car camera is divided into reversing camera and front view camera according to the function; according to the installation method, it is divided into special car and general external reversing camera; according to the camera chip system, it is divided into CMOS and CCD high-definition camera. Fengno recommends that you do not demand the camera to use the CCD image sensor when purchasing the car camera. The high-end CMOS camera can match the CCD effect, fully meet the requirements of the owner, and enjoy the price advantage.
Wire: Since the car camera is installed inside the car, the temperature of the working environment is relatively high, and the high temperature resistance of the wire of the camera becomes an important factor to test its quality. Most of the wire rods on the market today are made of (copper-clad steel), which is inexpensive and the quality is not guaranteed. After 5 minutes of work, the surface temperature will reach 100 degrees or more. The wire will be fused together for a long time, and it may cause spontaneous combustion when it is severe. Fengno's camera adopts car-specific wire, and the working temperature range is -20~70°. Compared with the conventional temperature of the vehicle-mounted camera on the market, it has high temperature resistance of 0-50°. And the heat generation is small, the heat insulation performance of the wire surface is better, and the service life of the product is longer. Car camera as a regular accessory for automotive electronics, Fengnuo recommends that you choose the special cable for the car camera when you purchase the camera to avoid potential safety hazards.
Lens: The lens of the camera generally has a plastic lens (plasTIc) and a glass lens. The plastic lens has a significant difference from the glass lens. The plastic lens is very cheap, but the imaging effect is obviously inferior to the glass. The raw material of the plastic lens is derived from plastic or resin, and the glass lens is derived from glass. Nowadays, many small factories use cheap plastic lenses in order to save costs and pursue high profits. Although the price is attractive, the actual effect is unsatisfactory, and the screen is yellow, dark and fuzzy. Therefore, Fenguo suggested that you can't just buy a car camera and you can't just look at it cheaply, or you should choose a well-formed glass optical lens to make the image clearer.
Imaging angle: The size of the imaging angle of the camera determines the size of the visible imaging area. The horizontal angle of the camera is too small (the rear view lens) can not be photographed in many areas, resulting in visual blind spots. The manufacturers in the market advertise that the car camera reaches a wide angle of 170°. This angle refers to the diagonal angle, but the angle that is really useful for the car is the rear view horizontal angle. At present, the rear view horizontal angle of the on-board camera on the market is mostly 80°~95°. The angle of the rear view horizontal line of the Fengnuo brand camera reaches 110°, which greatly reduces the visual blind zone behind the car (or front of the car) and fully satisfies The owner's need for safe parking. Therefore, it is recommended that when choosing an in-vehicle camera, in order to reduce the visual blind spot, it is best to choose a lens with a rear view with a large horizontal angle. Waterproof performance: Due to the special working environment of the car camera, it is exposed to the wind and rain all the year round, so the overall waterproof performance of the camera is very high. Industrial parameter markings are generally indicated by "IPXX", where "I" means dustproof and "P" means waterproof. The first "X" indicates the waterproof rating and the second "X" indicates the dust rating. Camera products with IP66 or higher can basically meet the needs of the working environment. As a professional manufacturer of in-vehicle cameras, Fengnuo's main structure is designed to be IP67 rated. All products are waterproof, aging, vignetting, reflective and other imaging tests, thus ensuring the quality of shipment.
Camera installation general troubleshooting:Picture jitter: The camera shake of the camera is generally caused by the looseness of the bracket of the fixed lens theme, causing the camera to tilt the picture. The recommended method is to adjust the angle of the bracket and fasten it to prevent loosening again.
No image: The camera has no avatar. Generally, the plug is not plugged in (loose) or the system connection line is broken. It is recommended to check if the plug is plugged in and the system connection is disconnected.
The picture is blurred: the camera picture is blurred, it is likely that the lens part has accumulated a lot of dust and is not clean. It is recommended to clean the lens.
Screen tilt: The screen display is tilted. Generally, the camera bracket is recommended because the main body of the camera is not installed.
