As an electronic auxiliary system for car driving safety, the installation of the on-board camera can greatly improve the performance of driving safety. Car cameras have become indispensable hardware for traffic safety. The quality of car cameras directly affects whether the reversing image is clear, and is it easier to be recognized by car owners? The following editor will take you to understand the common knowledge and troubleshooting of car cameras in detail.
Next, I will introduce the common sense and troubleshooting of the car camera
Car camera classification: Car cameras are divided into reversing cameras and front-view cameras according to their functions; according to installation methods, they are divided into special car-specific and general external reversing cameras; according to the chip format of the camera, they are divided into CMOS and CCD high-definition cameras. Fengnuo recommends that you do not ask whether the camera uses a CCD image sensor when purchasing a car camera. The high-end CMOS camera is comparable to the CCD effect, which can fully meet the requirements of the car owner and enjoy a price advantage.
Wire: Since the car camera is installed inside the car, the temperature of its working environment is relatively high, and the high temperature resistance of the wire of the camera has become a very important factor to test its quality. At present, most of the wires for car cameras on the market are made of (copper-clad steel), which are low in price and cannot be guaranteed in quality. After working for 5 minutes, the surface temperature reaches more than 100 degrees, and the wires will melt together after long-term use, and may cause spontaneous combustion in severe cases. However, Fono’s camera adopts special wire for vehicle, and the working temperature range is -20~70°. Compared with the normal temperature of 0-50° for common vehicle cameras on the market, it has high temperature resistance performance. And the heat generation is small, the thermal insulation performance of the wire surface is better, and the service life of the product is longer. Car cameras are conventional accessories for automotive electronics. Fonno recommends that you try to choose special wires for car cameras when purchasing cameras to avoid potential safety hazards.
Lens: The lens of the camera generally has a plastic lens (plasTIc) and a glass lens (glass), and the plastic lens is significantly different from the glass lens. The price of the plastic lens is very cheap, but the imaging effect is obviously inferior to that of the glass. The raw material of plastic lens is plastic or resin, and the raw material of glass lens is glass. Nowadays, many small factories, in order to save costs and pursue high profits, use cheap plastic lenses. Although the price is attractive, the actual effect is unsatisfactory, and the picture appears yellow, dark, and blurred. Therefore, Fengnuo recommends that you should not blindly covet cheapness when purchasing a car camera, but choose a glass optical lens with a good imaging effect for clearer imaging.
Imaging angle: The imaging angle of the camera determines the size of the visible imaging area. The horizontal angle of the camera is too small to capture many areas behind the car (rear view lens), resulting in blind spots. Manufacturers in the market advertise that the car camera has a wide angle of 170°. This angle refers to the diagonal angle, but the angle that is really useful to the car is the rear view horizontal angle. At present, most of the rear-view horizon angles of vehicle-mounted cameras on the market range from 80° to 95°. The rear-view horizon angle of the Fonno brand camera reaches 110°, which greatly reduces the visual blind spot behind the car (or in front of the car), fully satisfying Car owners' needs for safe parking. Therefore, it is recommended that when choosing a car camera, in order to reduce the blind spot of vision, choose a lens with a larger horizontal angle of the rear view. Waterproof performance: Due to the particularity of the working environment of the car camera, it is exposed to the wind and rain all year round, so the overall waterproof performance of the camera is very high. Industrial parameters are generally indicated by "IPXX", where "I" means dustproof and "P" means waterproof. "X" indicates the waterproof rating, and the second "X" indicates the dustproof rating. Camera products above IP66 level can basically meet the needs of the working environment. As a manufacturer of car cameras, Fengnuo has designed the main structure of the lens, and the waterproof level is above IP67. All products have undergone multiple imaging tests such as waterproof, aging, vignetting, reflection, etc., so as to ensure the quality of shipments.
General troubleshooting of camera installation:
Screen shake: The screen shake of the camera is generally caused by the loosening of the bracket that fixes the subject of the lens, causing the camera to tilt the picture. The recommended method is to adjust the angle of the bracket and fasten it to prevent it from loosening again.
No image: The camera has no avatar, usually because the plug is not plugged in properly (loose) or the system connection line is disconnected. It is recommended to check whether the plug is plugged in properly and the system connection is disconnected.
Blurred picture: The picture of the camera is blurry, which is probably caused by the accumulation of a lot of dust in the lens part and is not clean. It is recommended to clean the lens.
Screen tilt: The screen display is tilted, generally because the main part of the camera is not installed correctly, it is recommended to adjust the camera bracket.
