It is quite natural that drivers are affected by restricted visibility at times. This may be caused by condensation, fog, frost, or even badly lit parking garages where visibility is poor. A modern car design makes it difficult to gauge just how close you are to an object. It is very important for the car driver to detect obstacles otherwise it might lead to some serious problems. Rear parking sensors detect obstacles behind you while reversing - audible alarm and/or visual displays available with sensor units.

Kinds of rear parking sensors
Generally you can get 2 and 4 rear parking sensor units. Rear parking sensors are available in various colours and you can also avail colour matching service. Some manufacturers provide 2 and 4 front rear parking sensor units with dashboard mounted visual display unit.  The rear distance sensing might be up to 170cm while front unit sensing distances up to 90cm.

Rear parking sensors have 160 degree wide horizontal detection range and 60 degree wide vertical detection performance. Rear parking sensors have advanced ultrasonic asymmetric sensing technology with audio and/or digital warning system. 

The Parking Sensor uses ultrasonic technology to calculate the exact position of an object within its detection range. When reverse gear is selected, rear parking sensors is activated.

When an object comes within range, the rear parking sensor will emit a steady beeping sound to alert you. Once you move within 0.9 m of the object, the beeping sound becomes faster until you are within 0.45 m. At this point the sound becomes a constant tone to warm you not to proceed any further. Certain rear parking sensor systems include a digital display, which shows the position of obstructions.

Rear parking sensors are inexpensive
When backing up from your garage or your local grocery parking lot, rear parking sensors are useful.  Almost all luxury cars have reverse parking sensor which costs approximately an approximate $1,400 or more.  Car backup sensors are inexpensive to install and extremely useful.

Some of the top brands include Nissan, Toyota, and many other manufacturers. It is always best to buy branded rear parking sensors. They give you warranty and lot of other service. Another thing is that you must find an established outlet that fits them correctly. I guess they are a bit like car alarms, if you get them fitted properly they will work well.

Rear parking sensors are also fitted in small cars. This makes it a very special feature which the buyers look for when they compare with other cars. Rear parking sensors’ market is still in the nascent stage but it has huge growth potential in the long run. Hence all the major manufacturers are scaling up their operations to increase the technology and make it even cheaper.

I blame a good deal of the death of my elderly mother, Mrs. Beatrice Mills, from a careless driver who backed into her when she was sitting in front of a store in her wheelchair. She could not get away as the car backed into her and ended up in hospital. 

This was the start of many problems for my mother who passed away recently. I think if the driver of that car had parking sensors attached to his vehicle, she might still be alive.

A man who found out about car sensors at church from his vicar decided to purchase back up sensors for his car online and was glad that he did. 

Three weeks after purchasing back up sensors on a site called Parking Dynamics, the Manchester native avoided a parking accident with his elderly neighbor. 

I was coming out of a pub near Twickenham when two lads jumped me and stole my wallet and began beating me senseless. The last thing I remember was falling to the ground. A woman who was driving a car with a reverse parking sensor happened to be going to the pub that night and had it not been for her, I am not sure what would have happened to me.  

I had a concussion and needed medical attention right away. On top of that, I had fallen into a parking space and the pub car park was not very well lit. Anyone could have run over me. 

Parking sensors have become inescapable parts of modern automobiles. With changing design of the auto-motives, size, shape, design, and functionality of these sensors are also changing rapidly.

Most of today’s high-end parking sensors are electronics and sophisticated in nature. People’s ever-changing attitudes towards having unique characteristics in their loving vehicles have also forced automobile engineers to continuously modify the existing patterns of the vehicle accessories.

Sometimes, it is the emerging requirement that might cause new technologies or concepts to come in. Car rules also require that you should have well defined standardized parking sensors to make your vehicle road-worthy.

In any case, with parking space becoming increasingly congested, these stuffs with their powered efficiencies are gaining more popularity, as they help parking your vehicle safely in a most unreceptive environment.

Different Types of Parking Sensors

Based upon purpose, functionality, technology, location, and other design criteria, there exist various kinds of parking sensors; a hairline distinction may always not available amongst various groups of them.

You may wish to install them at the front and rear panel of your vehicle, or any one of the places. Few popular brands of the existing parking sensors are buzzer, wireless, digital, and camera & monitor enabled parking sensors, etc. There also exist reverse parking stuffs with their dedicated purposes.

Buzzer sensors become ideal if you have any visual difficulty, or otherwise also, they act as alarm to alert you about the spacious ambience. All types of these parking sensors do come with special kit comprising of number of small constituent elements that together make the particular parking aid system operational on your vehicle.

For example, an ideal buzzer type parking aid kit may consists of one electronic control unit with appropriate power cable, one alarm or buzzer with cable, 2-4 ultrasonic recessed sensors, 2-4 wedges or spacers, adhesive tape, cutting instrument to install the sensor, and suitable user manual, etc.

Driving with the Parking Sensors

If you have ever experienced driving a vehicle without the parking sensors installed, you know how difficult it is to park the car in an overcrowded parking place! Though, all of the space-sensing equipments do not work similarly, but their very purpose is the same.

With reverse parking support system installed, your efforts in parking the vehicle safely in the smallest of spaces become quite painless. Especially, during night time, parking sensors play very important role in guiding you park effectively and efficiently. Besides giving you the idea of available spaces, parking sensors can also be used to detect kids and other obstacles, thus enhancing safety norms while using vehicles on road.

Purchasing Parking Sensors

Purchasing most appropriate types of parking sensors with desired quality requires little knowledge on the type and make of your vehicle. Most of the existing types of parking sensors do come in the range of $30 - $200 for each individual kit.

If you are searching for a stylish set of parking support system, you may search various online stores to find most appropriate set for you. Besides, you must be careful to ensure that the kit you are purchasing is compatible with your vehicle. Every individual part must be checked as per the supplied manual for their serviceability and standard operating procedures

A five year old child barely survived a freak accident in a car park recently in Henley when he walked between two parked cars. The cars were parallel parked on the street and the child let go of the hand of his dad and began walking off the street and through the two cars. 

One of the cars had just pulled into gear and was getting out of the space. He was about to lurch forward when his parking sensor went off. Although the child was hit and received a concussion, he survived the incident. Had the parking sensor not been installed on the Fiat, the child most likely would have been crushed to death. 

Today’s world of hectic driving and increasing number of cars has put a huge pressure of parking space. Though the municipalities as well as builders are trying to tackle this problem by coming up with innovative and practical parking solutions, still parking spaces are becoming scarce and congested.

How many times you have dented or scratched you your car while trying to maneuver it into narrow parking space? The rear window mirrors and the dexterity of your neck do not seem to be accurate enough, do they? How you wish you had someone standing outside to help you and give a shout as you were veering dangerously close to any object?

Sounds good, doesn’t it? So should you get a friend installed in your car to always come with you while driving? No. You should get a car parking sensor installed in your car.

Car parking sensors are electronic or electromagnetic devices used for safely reversing cars. Statistics show that most of the accidents occur when a driver fails to accurately judge the proximity of his/her own vehicle from another vehicle while parking the car. Car parking sensors allow the drivers of all types of automobiles, such as trucks, cars or other light or heavy vehicles, to backup their vehicles safely while parking.

These car parking sensors alert the driver regarding any obtrusive objects in their parking pathway. Car parking sensors are also sometimes referred to as backup sensors or parking sonar. 

Usually, a car parking sensor is installed on the bumper or bracket of the car. These car parking sensors use ultrasonic waves, which are sent at 40,000 times / second, to detect any potential obstructions. A controller of the car parking sensor is installed inside the car that receives the signal from the car parking sensor, which it sends to a speaker or a speaker and display combination unit.

The speaker of the car parking sensor in turn emits a warning tone, and if a display is also present, which may either show lines or any other signal, depending on the model.

The most common warning signal in car parking sensors is the “beep” which is emitted whenever the car parking sensor senses any nearby obstruction. These audible beeps become faster and shriller as the distance between the car and the obstruction lessens.

Visual displays also follow a similar rule, with the lines on the display getting lesser as the car approaches a potential obstruction. A combination car parking sensor displays the lines and emits the sound as well.

Car parking sensors are available in the market with various features and variations.

My daughter, Emma, is three years old and quite a handful. Like most young children, she is very quick and lively. One day, I was bringing her in from an outing and she darted away from me, as children will often do, towards the driveway of my neighbor.

A young schoolgirl who was walking home from school cheated death as she was nearly struck down by an Alfa Romeo driven by a local Twickenham woman. Fortunately, due to the recent stories about the two Twickenham men who were caught after beating and robbing a man in a pub car park, the divorced mum had installed parking sensors on her Alfa Romeo car. 

Vehicle sensors are easy to find. You can get them on sites like Parking Dynamics and install them yourself on your car. They are mostly electromagnetic and easily fit on the back of your bumper or the under carriage of your car. If a vehicle or other object or person gets too close, an alarm sounds, similar to a car alarm. The driver then knows that it is time to stop the car.
