Before the auction, please check the product description, we will accurately describe the product, you know more about the product, allows us to trade, more enjoyable, thank you for your support.

Our commitment to the product:
I We have a professional service groups, capable, capable, to provide you with the best pre-sale and after-sales service.
1) before the product is sent, we will conduct a good power test every function of the product, to ensure good quality for you to send pieces.
2) electronic products, no one can not guarantee that no problem to 100% Moreover, have to go through the courier on the road to reach your hands, such as in case of product quality problems, we provide one year replacement service.Freight, In your receipt, 7 days, we are responsible for all of the Back Freight, within a month, you come to me, a month later, all by the buyer.
3) because of online shopping, you can not see the physical after the purchase, so we promise, 7 days without any reason to return, refund, freight, one responsible for half (premise: the product is not installed, You sign the date of counting)

Product accessories: 1 external speaker / microcomputer host 1 / angle with the supply probe 4/1 power cord / 22MM open a device / a strong glue 1 / manual 1
Introduction:
The system is equipped with imported ultrasonic sensors to detect whether there is an obstacle after the car is accurately measured.The principle is to use the microcomputer system operation command and control, Through the sound and display were prompted to the direction of the obstacles and the distance between the body and obstacles in order to achieve the collision prevention in unburned.

Before the radar knowledge, before you buy, you need to view, thank you

1) Q: Why is the car before the radar sensitivity is not high after the car.Why feel insensitive?

L Radar sensitivity, must be set low, because we are at high speed, the car will have a considerable wind pressure, such as radar, high sensitivity, which radar will wind when the obstacle, has been the police

Or rain, the probe will rain when the obstacles, resulting in chaos reported, it is necessary to set the product sensitivity is low.

Please make sure that the sensitivity of the rear radar is compared with that of the front

2) Q: Why is the distance from the front of radar detection?

Because the front of the radar, his main role is in the traffic jam, the car will be a small place to turn, parking, parking and so these small places to use, like a small place, you

The speed will be slower, so there is no need to detect what is far, if the detection is far, you are waiting for the brakes when the red light, the old car to detect the front, resulting in alarm, annoying.

There is also an important, is the height of the front of the installation limit.If the detection is too far, will detect the ground.

Because we are professional, so we focus more on every detail

The collision avoidance system features:
◆ When the front brake is on, the radar will turn on automatically. When the brake is released, the probe will be delayed for about 20 seconds.
◆Beep level by level prompt Obstacle distance.
◆ microcomputer intelligent control, from military technology, accurate and reliable.
◆Beep level by level prompt Obstacle distance, Not subject to environmental impact, rain, especially in the night advantage.
◆ anti-electromagnetic interference, patented technology, international certification. Quality assurance. Original electronic system without any effect.
◆ probe with embedded installation, multi-color configuration sensor compact, easy to install.

Car reversing radar technical parameters:
◆ Detection distance: front: 0.3-1.0m
◆ Operating voltage: dc12v (+ - 2v)
◆ operating current: 20ma-200ma maximum power: 2w
◆ ultrasonic frequency: 40khz detection angle: h> 80 degrees v> 70 degrees
◆ Operating temperature: -20c ~ +80 c Warning volume:> 70DB

Alarm prompt mode:
◆ voice prompt: the system used Beep level by level prompt , The more obstacles, the more rapid

Users are most concerned about

1) How sensitive is the product?

On the sensitivity, which many users, there will be a misunderstanding, the radar is not the higher the better sensitivity, of course, can not say that the lower is good, the product should take a moderate sensitivity, the sensitivity should be by the manufacturers through long- And adjust the good, which will be some cottage products, in order to meet the user's hobby and do not understand the product, the sensitivity transferred to the highest, this will make a lot of false positives radar, such as: rain rain glued to the probe surface, On the sensitivity, in fact, users simply select the brand of radar, do not worry, because only brand products, they will be concerned about the effect of their own brand , And will not disregard the stability of product quality, and blind to meet user requirements.

2) How accurate is the product?

Radar is sent through the vibration of ultrasonic, ultrasonic obstacles encountered, reflected back, the radar received and calculated by the data. Ultrasonic reflection back how much, it directly affects the accuracy of the radar. , The radar will calculate more accurate, so different obstacles, get accuracy will be different, such as the car after the obstacles are: the activities of the human body, high-speed sports car, small cylinder, etc. , They reflect the surface of the ultrasound is not the same, if facing the wall, slow test, we can ensure that you can get high accuracy, so this accuracy can not be calculated, we can not accurately To give you a reply.

3) Can I install this product myself?

Product installation wiring is very simple, but the ability to see people hands. If you do not understand, we recommend looking for experienced technicians to install.
