car camera, is a vehicle for acquiring sound and video products and equipment, road traffic monitoring, vehicle driving safety plays an important role, but also provide the required certificates and other real-time audio and video in some cases.
1. The vehicle camera works
camera power connected to the reversing tail lamp, when the reverse gear is engaged, the camera sync supply into operation, the collected video information through a wireless transmitter placed in front of the car to a wireless receiver, the receiver the video information transmitted through the AV iN GPS navigation interfaces, so that when the receiver receives the signal, whether it is in any Gps navigation interface, the liquid crystal will screen provides priority for reversing video video.
2. The characteristics of the vehicle-mounted camera
First, the chip
CCD and CMOS chips are an important part of the reversing camera, according to the different elements can be divided into CCD and CMOS. CMOS low image quality are mainly used in products, it has the advantage of manufacturing cost, lower power consumption than the CCD, CMOS camera disadvantage is the higher requirement for a light source; CCD, is used in photography, the image pickup element further aspect of the high-technology It comes with video capture card. CCD and CMOS technology and performance in large gap, in general, CCD is better, but the prices are more expensive, we recommended to choose the CCD without considering the premise of the cost of the camera.
Second, the water
reversing camera basically includes a waterproof product, to avoid rain erosion performance guarantee normal play.
Third, night vision
night vision with clarity regarding the product, the higher the clarity of night vision products are very good, this is because of the chip itself, but good quality of products have night vision, but not the image of the object like the effect, although the color will be worse, but clearly not a problem.
Fourth, the definition
definition is an important indicator to measure the camera. In general, high-definition image quality of its products will be better, for the present-definition products in the 420 line has become a mainstream product reversing camera, if the debugger can also choose a good 380 line. However, depending on the level of each chip camera, different photosensitive element, including the technician level debugging, the same chip the same level of product quality possible presentation of the results will be different, opposite, high-definition night vision products will play some discount.
In summary, the choice of reversing camera, can be considered from the above aspects, the most important is to look at, to compare the actual effect of the image, Better play its performance.
