Those with an average sized vehicle, face the daily challenge of getting the car in and out of the garage ensuring that the vehicle has suffered no damages along the sides. Garage parking is even more difficult with those who have large sized cars of 4-by-4. The car backup sensor can be a great assistance while backing up the car into the garage. With a parking sensor, you can safely park the car and drive it through a limited space without any damage done.

There are many garage parking sensors, which can be fitted to the walls of your garage to alarm you from colliding with any object. These parking sensors start sensing and raise an alarm, when the vehicle is in danger of hitting an obstacle. These are ultrasonic sensor units, which determine the distance between the car and the wall. It provides a guide light that is displayed to the driver on the "traffic light" display. 

There is other laser-guided garage parking sensors aid, which is more reliable and easy to handle. This device makes it easier to know that the car is heading towards the garage wall. These devices are equipped with lights. The color of the lights change and indicate when you need to advance or when you should slow down, or when its time to halt. The unit also enables calculation of the distance between the garage wall and your car. Further, the system also encloses a memory module, which remembers the preferences of the driver.           

Another sophisticated garage parking sensor is The Park ‘n Place, which is quite simple to use. Moreover, it is easy install the unit. Just the different parts have to be snapped together and set in. The face of the sign lights up when the car hits the sign and it will move slightly.       

Built-in Parking Sensors

There are built-in backup sensors, which might help to park cars in garage. However, these do not correspond to the average dimension of all garages. These are especially ineffective with the large cars, which are not planned according to average garage size.  
   
However, the latest electromagnetic sensors score far over other sensors. The Parking Dynamics PD1 is one such system, which offers excellent reverse parking sensor or garage parking sensor. These can be installed on the front and rear bumpers for greater parking protection. Just wire the PD1 with an independent switch, which can be placed in front or rear of the vehicle. Now, you can drive your car safely into the garage. Moreover, PD1 is 100% accurate in all weather conditions and its easy 3-wire easy installation does not even require you to make holes on the car bumpers. 

Car alarms combine intelligent software and advanced technology to ensure impregnable vehicle security. The alarms are stylishly designed and safe to use. Further, accompanying a range of options and features, car alarms are a choice of many.

Some of the noticeable features of car alarm include:

- The unit consists of automatic setting for dual circuit immobilization
- Ultrasonic interior sensors are provided, which are easily switchable
- It offers a central locking system with simple closure
- The car alarm also encloses a high power battery back up siren
- Electric window controls provide
- The system incorporates cell phone hands free kits for more convenience
- Flashing interior LED enhances the security

The car alarms are compatible with all types of autos and designed to offer quality protection to the car at a sensible price. Further, these systems can be customized according to the vehicle-make and the buyer’s budget.

How it works?

Car alarms feature interior sensors, which can sense and detect when the car is tilted, or the glass is broken or even if the car is being jacked up to steal the wheels and tires. Sensors of the device triggers alarm, if there is an intentional or accidental collision. This alerts the owner of the vehicle about an attempt of theft.

Apart from providing high security, the car alarms also double up as parking alarm. It is quite difficult to manage parallel parking systems, which involves higher risk of collision while moving in or out of the space. The system alerts the driver if the car is too close to the wall, to avoid wrecking. These systems are more beneficial than the blind spots. With such an alarm, parallel parking becomes simple and it is easier to back up.

Are there better options?

Yes, the PD1 parking sensor alarms are exclusively designed products compatible for almost all types of autos. Equipped with state-of-art-technology, PD1 is incomparable when it comes to quality and features. Not only easy to install, but this alarm system also provides invaluable and timely protection from dangers. Moreover, what makes PD1 an obvious selection is its price, perfectly reasonable for the peace of mind that it offers to the users.

The latest garage parking aids are sophisticated devices, which makes car parking easier and safer for the driver in congested areas. Parking aid manufacturers have developed parking sensors that alarms the driver on the obstacles lying behind the car. Such a parking aid is of great help for those who are not comfortable with the rear view mirrors and fear accidents. One of the most common fallacies with the drivers is that they forget that the objects in the rear view mirror are closer than they appear on the mirror.     

Normally, the garage parking aid encloses two devices - rear parking sensors and front parking sensors. The parking sensors assist in parking your car in the garage efficiently and perfectly. It provides an idea about the place where the obstruction is located. There are garage parking aids suppliers who offer a variety of devices according to your needs.

Different Types of Garage Parking Aid

There are different types of garage parking aids, categorized on the basis of make and functions. Some of the parking aids use markers, others have floor stops or still others use sounds or electronic beams that help to locate the parking space precisely.    
 
One of the latest parking aid devices are those with camera and LCD screen. The device comes with two cameras that can be hidden under the front or back bumper or placed on the front and back indicator panel. These cameras attached to the car transmit live, clear and sharp images of the objects, which appear in front as well as behind the car. These garage parking aid devices come with LED screens, sensing device and alarms, etc.      

Ultrasonic Garage Parking Sensor

It is a high-tech garage parking sensor, which is also known as Park-zone. It appears as a space age traffic light. This is really an amazing device to have in your car. Overall, it is a guiding-system for a parking car.      

This device is hung on the wall and prevents guides that helps the driver to stop the vehicle exactly where it is required, calculating the distance from the wall. However, this advanced system is quite easy to operate and far more superior than the sensor technology. Hang the system on a carport wall or a garage and decide the park zone by setting the distance of the wall from bumper through the ultrasonic sensor. The device would surely locate the spot with precision whenever you need.
 

In some vehicles, sensors come as factory-fitted item. Further, there are different parking sensors available in market to fit different vehicles. However, since there are different parking sensors it is quite difficult to determine their efficiency without knowing their operational capabilities.
 
Types of Parking Sensors
 
In general, the parking sensors can be divided into two categories - Electromagnetic systems and Ultrasonic systems.

Essentially, the ultrasonic sensor emits an ultrasonic signal, which is reflected by an obstruction. When the sensor gets closer to the object, it starts emitting signals faster to the sensor. This signal is converted into audible sound. This is received in the form of an audible warning. Depending on the distance of the object, the beat of the audible sound lowers or grows louder.  The driver has to react to the audible noise.

The ultrasonic system is an older technology with 4 to 6 sensors mounted in the bumper and are visible to all. In order to mount the sensors, holes have to be drilled in the bumper that might spoil the look of your car. Further, you need to paint them to match color of the bumper. Some of the cars enclose crash protection bar behind the bumper, in such cases the ultrasonic system has to be installed in depth of the bumpers. There are quite a lot of hassles involved with ultrasonic parking sensors, which has popularized the more competent system of electromagnetic sensors.  The electromagnetic sensors have overcome the shortcomings of the ultrasonic parking sensors to a greater extent.  

The PD1 is one of the most successful parking systems making use of the unique Electromagnetic Technology, which is typical with only a few privileged cars manufacturers. These sensors are immaculately designed to be fitted easily, without compromising with the ‘new factory look’ of your car. This electromagnetic system operates by creating an electromagnetic field in the vicinity of the sensors. Any kind of intrusion in the force field generates a warning.   

In contrast to Ultrasonic technology with 4 to 6 exposed sensors, which requires regular cleaning and maintenance, the electromagnetic technology is concealed and self diagnostic. Therefore, it requires no maintenance.       

Some of the cars have edges on the bumpers, projecting from the rest of the body. Most often these edges are battered, since the driver is unable to see the corners. The electromagnetic units are designed to avoid such collisions. The antenna of the electromagnetic system covers the entire length of the bumper, which detects objects at the corners and sides.      

Further, the electromagnetic parking sensors have no visible parts. These are fitted discretely and are hidden. It is only the driver who knows that it is fitted. It ensures that there is no problem with installation. The PD1 can be fitted without drilling the bumper and it is completely discrete and invisible when on the vehicle. With the electromagnetic sensors your car now has higher value and is a more desirable car.

Initially developed for automotive application, CAN bus is compatible with international standards. For this reason, it is extensively used to for generating control system. Since CAN bus is used in huge volumes, all its components are available at affordable rates. It has high transmitter reliability and high transfer rate. In addition to recognizing data error, the system is perfect for controlling noisy environments.   

 Most of the automobiles today have Electronic Control Units (ECU) for different subsystems. Normally, engine control unit is the biggest processor in such a system. Other units are also included like cruise control, audio systems, windows, mirror adjustment, transmission, airbags, anti-lock braking etc. Out of these, there are some subsystems, which work independently, however the others need to communicate with each other to function. The subsystem must obtain feedback from sensors as well as manage the actuators. This communication is accomplished through CAN.  

PD1 CAN Bus Wiring Systems

 One of the most compatible CAN bus wiring systems - Parking Dynamics PD1 is easy to install and requires no adjustment or extra equipments to install. This CAN Bus multiplex wiring system are successfully used in cars and vehicles. Moreover, these systems are more popular than other ultrasonic systems which require extra wiring and relay components to integrate with the CAN bus.  

How it works?

CAN is connected to Electronic Control Units (ECUs) through different serial bus standards. Each node uses a host-processor to send or receive message. However, this is not done simultaneously. The message with an ID (chosen to identify the message sender or type) is transmitted serially onto the bus. A message of up to eight bytes can be sent with each bit transferred one-by-one. The signal-pattern codes the message and all the nodes interpret it.  

The vehicles may use the CAN bus to connect the transmission to engine control unit, or connect the seat control, door locks, climate control, etc. on a different bus. Due to the low cost of CAN controllers and processors, these also serve as field bus in general automation environments.  However, for official use of CAN, it is required to pay a fee to acquire a CAN Protocol License.

The best electromagnetic parking sensor - PD1 from Parking Dynamics is installed through a 3-wire installation method. Moreover, it is provided with Universal Installation Instructions, which makes the process of installation not only easier, but also more safe and simple. Going through the instructions even a novice may accomplish the job of installation perfectly.

The Parking Dynamics PD1 systems are no drill, ultra discreet, reliable and high performance product, which can be easily fitted into a range of cars. The PD1 is compatible with most of the vehicles with plastic bumpers. However, it’s not a matter of concern even if the bumper is partly metallic.

For successful Electromagnetic Parking Sensor installation, you need to follow the process provided below:  

Mounting the Unit

To begin with, install the unit adjacent to the reversing light behind the trim and attach to the trim or body. However, it would better to choose the passenger side. Now, the antenna wire from the unit is passed through the hole (provided by manufacturer) with the grommet fitted joining the antenna on the bumper. However, if the hole is not provided it can be drilled, and the wire can be passed through it with the grommet. In case, there is no space behind the vehicle, the unit can be behind the bumper.        
      
Electrical Connections

The black wire is used for earth connection. It is connected to the ground chassis of the car. Attach the earth wire close to the light cluster at rear of the vehicle.   

The red wire is a 12V supply wire, which lightens up when the reverse gear is selected. It has to be connected to the light cluster situated at the rear of the vehicle. The white 4 pin of the connector should be plugged into the electronic control unit.      

The black twin wires have to be added to the spade terminal. Fit the white connector to the electronic unit and run wire with spade.  Connect it to an adhesive antenna with the connector. 

Mounting the Speaker

The speakers of the parking sensor can be mounted on the rear parcel shelf or the plastic trim or shelf with the help of adhesive mount. The unit has a good volume enough for a warning, even when it is mounted on the trim. It can be done through a push fit connection.   
 
Removal of Bumper

Most of the vehicle bumpers are made from plastic. Depending on the car, Electromagnetic Parking Sensor installation like PD1 can be accomplished by removing the bumper or just by relaxing the bumper by loosening the screw.  

If you are not willing to do it yourself, you can also hire a mechanic, auto electricians, or body shop technicians for installation, who will do the job, literally within minutes.

- Broadly, the parking sensors are found in two categories. One falls under the Ultrasonic System and the other, Electromagnetic System.

- The Ultrasonic sensors: In this type, the sensors send out ultra violet waves that instantly catches the presence of any obstruction in the car’s proximity. The nearer it gets to the focused point the faster it is able to send the signal. To make the driver alert of the detected object and its position, a circuit is made to send a signal through an audible device.

- The Electromagnetic Sensors: These types of sensors, unlike the Ultrasound System create an electromagnetic field within the vicinity of the vehicle. The object starts signaling instantly, soon after they fall into the created electromagnetic field of the sensors. 

The constitution of the Electromagnetic Sensors

Though it is the Ultrasonic sensor that is mostly found fitted in the cars, yet the modern electromagnetic type is preferred more to it. While for the ultrasonic sensors it is required to drill holes in the bumper of the car, the Electromagnetic ones are simply placed behind car’s bumper. The entire electromagnetic unit comprises an aerial, an electronic unit, acoustic sounder and a bi-adhesive tape to fix the aerial atop the bumper. Once fixed, this no hole parking sensor sends out signals to the driver as soon as any object fall into the field created near its vicinity.

The advantages of no holes car parking sensor

The Electromagnetic parking sensors are designed to provide protection to the car, keeping it absolutely intact. The sensors are fitted such that they remain invisible to the outsiders. Moreover, as they can be placed behind the car’s bumper without any drilling, the sensors are compatible in all situation and circumstances. Unlike its other competitors in the market, the Electromagnetic sensors are easy to handle and install. While the others require much of wiring, painting and mounting behind the bumper, the electro magnetic sensors are completely free of those chaoses. 

The many advantages over the others

The ultra Electromagnetic no holes car parking sensor has proved to be extremely suitable for cars and other vehicles while parking. Since they are located invisible from the outside, they have the minimal chance of suffering any external injury. Besides, alerting the drivers of the nearby cars and other vehicles in the parking lot, they are also capable of catching signals from a child or a wall obstruction behind the vehicle. In addition to that, the sensors are known for their 100% efficiency and the special forte of working for long in all weather and other conditions.

Why no drill parking sensor is best for you

Most people look for sensors that can be easily fitted, such as the latest parking sensors featuring electromagnetic technology. These are universally compatible with any small van, car, caravan and other autos. Such sensors have no visible part and needs no drilling of the vehicle bumpers. Designed to fit all conditions, a no drill car parking sensor can detect any person, vehicle or any other object located even behind your car. The sensors provide you with early warnings, which prevent serious collisions. 

The no drill car parking sensor has an edge over the Ultra Sonic sensors, since it saves you from drilling of the bumpers, mounting, and painting or managing wires hanging over the car. After installation, the sensors are invisible and totally discrete. In contrast to the ultrasonic parking sensors, the no drill variety can be easily mounted and there are no worries of matching the paint colour as you have made holes to install the sensor. Further, these parking sensors are maintenance free. Damage or faults in the Ultra Sonic sensors may require rewiring. Further, there is no need of cleaning, adjustment or testing of the sensors. Given that your car is more safe and protected from unnecessary collisions.   

More Information on the Electronic no drill parking sensor:

- The electronic parking sensors use low energy electromagnetic waves for sensing obstacles   
- It assists the  driver in  parking cars in areas with small spaces easily 
- It is quite easy to install the device as it is free from hassles of drilling, wiring or painting  
- Replacement of the system is cost effective as it requires no re-alignments or adjustments during 

With the EPS Parking sensor, you can park your car in narrow spaces quickly without the fear of the obstructions hidden from your view. The system alerts you if there are kids or low walls behind your car, which can’t be seen through the rear view mirror while you are on the reverse gear. With the sensor added to your car, it will have a higher value and be more comfortable and safer to drive.

A reverse sensor is designed to assist the driver while reversing the vehicle by emitting a beeping tone when an obstacle comes in close proximity behind the vehicle. The tone produced by the device assists the driver to avoid damage from bumping into other vehicles or obstructions.    
       
Types of reverse parking sensors

Although there are several types of reverse parking sensors, they can be divided into three broad categories - 4 sensors system, 6 sensor systems and parking system having a rear camera.  

• 4 sensors system: These comprise a main unit, simple monitor that shows left to right distance and 4 pieces of radar sensors.  The simple monitor with left and right LED light bar, in addition to central digit display makes parking a lot easier.  Especially those with a buzzer are really helpful.
• 6 sensors system: It includes a main unit, a monitor and 6 pieces of radar sensors. Two of the sensors are installed in the front corners and rest four sensors are installed in the rear.  These parking sensors help the drivers to look out the front corners. There are two types of monitors available, LCD and VDF monitors.  However, it is difficult to view the LCD in daylight, whereas the reverse parking sensor with VDF is suitable for all climates.        

Parking system with rear camera: Such systems consist of night vision CCD camera and 4 radar sensor. Certain systems also come with monitor like rear view mirror with 7" TFT LCD. The system is an excellent aid for reverse aid and parking. This backup sensor helps the drivers to view what is going on behind the vehicle.     
 
Working of parking sensors 

In the reverse gear, the system gets engaged in an immediate, self-diagnostic, automatic function of mapping the obstructions in the surrounding area. This constant monitoring of the bumpers assists in reversing the vehicle with 100% accuracy. It offers three different audible tone Zones according to the distance of the obstacle from the space. This alerts the driver on proximity with the surrounding objects.  There are also reverse sensors with LED display indicating the distance from an object. Therefore, a reverse parking sensor relieves the driver of worries about accidents while reversing.

Invisible electromagnetic parking sensors

Increasing cases of theft has lead to the emergence of invisible car parking sensors. Latest Electromagnetic Parking Sensor (EPS) system is completely concealed by sticking the strip sensor on the inner surface of the bumper. The system consists of acoustic alert unit, strip aluminum sensor and control module. Appearance of the bumper doesn’t change after installation of the parking sensor. It offers total protection to the back of the vehicle avoiding any blind spot close to the bumper.     

On applying the reverse gear, the parking system is automatically activated. An electromagnetic field is automatically generated by the strip sensor. As an obstacle enters the electromagnetic field, the field is perturbed which results in a change in relation to the distance of the obstacle.  This perturbation gets detected at a distance of eighty centimeters ahead of bumper. This is transformed into an acoustic signal that increases as the obstacle gets closer. Actually it is a proximity sensor, which is automatically activated with the insertion of the back gear. 

The EPS has been pioneered in the market to reproduce a completely new system with a flexible metallic strip hidden INSIDE the bumper. The most unique feature of the parking sensor is that it is completely invisible from outside when installed. The object near the bumper of the car is picked by the EPS parking sensor. The field of the sensor is not dependent on two or four sensors; rather it covers the whole length of the bumper. Therefore, these systems don’t miss any area like the normal ultrasonic systems.

Unlike the visible oval or round sensors drilled into the bumper, which spoils glamour of today’s prestige cars, these sophisticated devices are perfectly concealed. Further, as the electronic control unit of EPS is very compact (almost the size of a cigarette pack) they can be comfortably installed in the baggage compartment of the car. Additionally, since the parking sensor is invisible and installed inside the bumper, it has lesser risk of damaged.
 
Merits of the electromagnetic parking sensors

• These can be easily concealed during installation and doesn’t modify the vehicle appearance. 
• It gets activated automatically on engaging the reverse gear
• The detection range of the device starts from 0.8m approximately
• Acoustic signal becomes strong as the object gets closer
• The device guarantees better and more efficient maneuvering during the parking operation  

An invisible parking sensor could be your best purchase; it would not only prevent an accident but also save a life. Moreover, it improves the security of your vehicle and you can park it with no one required to watch.
