When you are consider buying a car, regardless of the model you want to purchase, thousands of US dollars or tens thousands of US dollars, there is still some car models are without parking sensor ( same as reversing radar ) and reversing camera.Fortunately, both products can be easily purchased online or at auto parts store. Today, we are going to discuss: Is it better to use reversing radar or is it better to use reversing camera ?

First of all, let’s talk about reversing radar, since it is being called radar, then its working principle is of course learned from bats. The radar probe emits ultrasonic waves. Once the ultrasonic waves hit obstacles, they will be reflected back. Then the system will calculate the distance between radar probes and obstacles. Then the driver is given different frequency alarms by the system according to the distance to help the driver better determine the parking position.

In actual operation, changes in light have no effect on the reversing radar. Even if it is raining heavily, it will not affect the reversing radar too much. Unless the probe is covered by a piece of mud, it will lead to false alarms. Of course, these premise is that you have bought a good parking sensor. Some reversing radars have virtual image display, and there are distance broadcasts, which can effectively help the driver reversing. However, some reversing radars only have alarms. For car owners who cannot see the blind spots, they cannot fully believe the reversing radars, because low position stones ( lower than the , iron pillars, or snow pile maybe ignored by the sound waves and the radars will keep silence.

In other words, objects that are shorter than reversing radars have the opportunity to escape from its detection. If you continue to reverse the car at this time, you may encounter obstacles. And some reversing radar with poor respond ability, it will take a certain reaction time before the alarm, so the speed must be slow when reversing

The reversing camera is equivalent to a real-time video monitor used when reversing. It is more vivid than the reversing radar. No matter whether it is a low rock or a thin iron pillar, they can’t escape from its eyes. For living creatures that move, it allows drivers to better understand the situation behind them. With reversing camera system, kids playing behind the car can easily being found and drivers can easily avoild of unnecessary accidents.

In actual operation, reversing camera performance has a great relationship with the reduction degree of the camera. For example, a reversing camera with a wide angle may cause the scenery on both sides of the screen to be distorted, thus affecting the correct judgment of the driver. Of course, there are some good reversing camera system, they have been designed with predict function, such as when you turn the steering wheel, the virtual line in the screen will changes according, so that the driver can better determine whether to continue reversing, or forwarding to re-adjust the car body position. However, the reverse camera also has its drawbacks. When the camera lens is covered with water or other dirt, or when bad weather (such as heavy rain) is encountered, it cannot work properly.

Saying for a long time, it is difficult to pick which one is better from the two. After all, their market prices are not much different, and the installation steps are almost the same. They also have their own advantages and disadvantages. So the final suggestion is if you feel that you can reversing easily, it doesn’t matter if you choose one or the other. However, if you still have problems reversing to some spaces , then we would suggest you to to install the both types. Actually, reversing radar and reversing camera are like the ears and eyes when reversing. Better not to rely on one alone, better using them together to complement one another.

Are you planing to buy and install rearview camera system for you own can or other vehicle, to improve reversing and parking safety and efficiency ? If yes, you definitely need help on how to choose the right rearview car camera system. Rearview camera system can be divided into wired rearview camera system dan wireless rearview camera system ( also being called WiFi rearview camera system).

For individual buyer or if you want to DIY rear view camera system, you’d better buy wireless rear view camera system. In fact, even the wireless rear view camera system still have a lot of wires, they are called wireless because they don’t have the video cable you need to wire between the camera and the lcd display, which is the most difficult part for DIY rearview camera system, becuase it cost you a lot of time to route the video cable throughout the vehicle. Instead, the wireless rearview camera system has a digital singal transmitter with the camera and a singal receiver with the lcd video display.

Other than that, wireless rearview camera system and wired rearview camera systems are much same. They both need a power source to run the car backup camera , they both are usually wired to the backup lights so that the system activates when the vehicle is in reverse only.

Wireless rearview camera systems work best when the distance between the transmitter and receiver is the shortest. That means that they usually work better on smaller vehicles than on large SUVs or trucks.

Factors you should pay attention to when purchase a wireless rearview camera system

Water Resistance
The heart of any rearview camera system is the camera itself. The reverse camera you choose should have a waterproof rating at least IP67, IP68 or IP69K will be better.

Penglihatan Malam
The camera should still work very well even at dark night, this functions usually requires the camera with built in infrared lights.

Mounting
There are many types of cameras with a variety of mounting methods, but the easiest method for installation are the license plate bracket models. They prevent you from having to drill more holes to mount the camera.

Height Tiltable
Make sure that a camera mounted to the license plate bracket can be height adjusted via tilting or you may be stuck with a view to the rear that isn’t ideal.

Sudut pandangan
Viewing angle is important when it comes to any car camera. Make sure the camera you choose has at 170 degree or better angle so that you can capture the whole area behind your vehicle.

Distance Detecting Line
Some cameras come with a built-in distance scale line display to help with backing up your vehicle and it is a really nice feature to have.

Video Monitor
Video monitor sizes for back up cameras have gotten larger over time. A 7 inch lcd video display definitely provides a better picture of what’s behind you than a 3.5 inch display, but it also occupy a lot of space on your dashboard. But think about where you can put the display before you made the final decision. Remember that you only use it when you back up and otherwise it’s just going to mounted to your dashboard or windshield, and take up a lot of space. For any WiFi backup camera system you buy, the monitor should activate automatically when it receives a video signal and the signal from the rear view camera should have the first priority over other possible inputs.
