OBD Car Tracker Plug & Play GPS Tracking Device

Car tracking has become the need of the hour, and car owners certainly want their car to be safe. When people look for these devices, there are lots of options available in the market. This is not about the brand, but the various categories options can place one in a dilemma. Here is a detailed description of the types of trackers available in the market, and accordingly you can choose as per your needs and convenience.

There are 3 types of trackers available in the market.

• Hardwired
• Portable
• OBD

Hardwired Trackers

This kind of GPS trackers is for monitoring a single vehicle. These are mostly used in the vehicles of earlier than 1996 where the OBD II ports were missing. It is preferred for the car owners who want to hide the installation for greater security. The electrical system of the vehicle is used for power, and there is no need to charge the device manually.

Portable Devices

These are perfect for individuals to use on their cars, and who travel more frequently. This is a real time tracker that caters to the need of many users. These are modern devices, and the accessories are included in the package like a micro USB cable, lanyard and waterproof case.

OBD Plug and Play Chargers

This is a perfect choice for tracking not only a single vehicle but a fleet of vehicles. Using the OBD car tracker has lots of advantages for the users.
• The installation is simple, and it takes only a few seconds, say about 30 to 45 seconds.
• The plug and play real time tracking device can be fitted to the OBD II port of the car's dashboard.
• There is no need to charge this device manually.
• Telematics is captured immediately, and the same is informed to the fleet owner. This helps the owners to ensure that the car is safe, and out of problems.
• Any misuse of vehicles will be notified with no delays to the users.

Apart from these advantages, many features are alluring about the OBD plug and play tracking device.

• The operating expenses are reduced, as the shortest routes can be chosen.
• The company's productivity can be increased as the employee can always exceed if the employees are misusing the vehicles.
• The vehicles can be effectively monitored round the clock, and the money saving is made easy, as fuel consumption is lowered.
• With the OBD car tracking device the vehicle utilization is maximized.
• The field staff can be managed with ease, and corrective actions wherever and whenever required can be taken.
• Route planning can be done with ease.
• The exact location of the vehicle can be traced at any given point of time.
• Dispatch inaccuracies can never happen, as the vehicles can be tracked for all reasons behind the delay.
• Administration account is single and managing the same is easy and non-complicated.

Precautions

Finding the right OBD port is a must, and for a few vehicles, these may not be compatible. But compared with the downsides of the hardwired devices which include the requirement of an auto electrician to fix the device, and the device being not portable, the disadvantages of the plug and play devices are negligible.

How To Detect GPS Tracking Units

The new GPS auto tracker technology allows just about anyone to track anyone else. In addition almost all new cell phones have GPS tracking capabilities built in to them. Some even have the ability to transmit location information even with the battery removed. All of which make you wonder what happened to personal privacy. The answer is that there really is no privacy. Granted there are legal restrictions as to how and when you can use the new tracking technology however detecting GPS tracking units can sometimes be difficult.

There are basically two types of GPS tracking device technology available to the public. The simplest is called a passive or logger tracking device. This device is also the most difficult to detect and defend against. These devices can be as small as a matchbook and can be hidden just about anywhere. They are attached to a vehicle or individual and after a specific amount of time they must be retrieved. After retrieval the device is usually attached to a personal computer and the information is downloaded into a data base that is provided by the device manufacture.

Probably the best defense against passive/logger tracking devices comes in the form of a GPS blocker. These small units normally plug into your automobiles cigarette lighter port and provide protection for about 30 feet in any direction. Small handheld units are also available that run on batteries that also provide short range blocking. These units can range in price from $200 to $850.

The second type of GPS auto tracker or personal GPS tracking units are called real time tracking devices. These units do just as the name implies, provide current real time location information on the individual or vehicle that is being tracked. This accomplished through the use of cell phone technology. Recent technology improvements have greatly reduced the size and reliability of these tracking devices. You can purchase a battery operated unit the size of a small cell phone that will provide tracking information for up to a week before the battery requires charging. More commonly these units are attached to a vehicle and use the vehicles power supply to provide power to the tracking unit.

Real time tracking devices generally require the user to contract with a GPS tracking service company. These companies frequently provide the tracking devices and the software necessary to track the device on your personal computer. Depending on the contract the information is uploaded to you at time specific intervals. The most common information uploads range from 5 to 10 minutes.

Defending against this type of tracking device is relatively easy with a combination cell phone/GPS blocking device. These units range in cost from $300 to more than $1000. Of course either a cell phone or a GPS blocking device may accomplish the same affect. In addition if you feel that you are being tracked illegally you can contact your local law enforcement agency and let them do a scan of the vehicle or personal effects in question. Many small law enforcement agencies do not have this capability and in that case you have the option to purchase a scanning unit and do the scan yourself.

A word to the wise if you are involved in a criminal enterprise. Much of what we have outlined here will not prevent US government agencies from tracking you and your vehicles.

In most cases it is illegal to track just about anyone without their permission. However given the fact that is so hard to detect many tracking devices it is likely that illegal GPS auto tracker and personal tracking device technology will continue to be used.

Mercedes 126 Repair – Tracking Down Vacuum Leaks

Mercedes always had a penchant for using manifold vacuum as a control device for various ancillary systems. As elegant as that may be, it does result in an engine compartment with a multitude of vacuum lines and connections, on top of an already-complicated fuel injection and air-management system. If that myriad of components has never been renewed on a 20-year-old car, there will almost certainly be leaks, and they can be tricky to track down.

Vacuum Leak Symptoms

Major vacuum leaks will make the engine very rough or lumpy at idle as the optimum air-fuel (A / F) ratio is compromised by the intake of unmetered air. The car may still drive reasonably well, because the relative magnitude of the leak becomes much less significant as the throttle opens and the engine draws in the large amounts of air it needs for combustion under load. Idle speed may also be elevated, as the vacuum leak frustrates the efforts of the idle-control system to regulate the amount of air admitted to the intake ports.

The economy gauge in the instrument cluster should be pegged left at idle (except in gear with the A / C on). But this gauge is not accurate enough for proper diagnosis. We really want to connect a hand-held vacuum gauge to the intake manifold. The best place to do this is at the back of the manifold on the passenger side, where the gray line to the interior accessories takes its feed. A healthy engine at idle, according to most textbooks, should indicate 17-22 in / Hg of vacuum; In the case of a V-8 Mercedes 126, we should be seeing around 20. A lower number can indicate many things, including improper ignition timing and generally poor engine condition. But if the engine is other sound sound, vacuum leaks will be noticeable here.

Best Detection Method

One way to find vacuum leaks is with an automotive stethoscope. You may be able to actually hear the intake of false air. But the best way is to use your car's oxygen senor as a diagnostic aid. The oxygen sensor on the early V-8's is a single wire device, sending a voltage close to 1.0 when the A / F ratio is very rich and close to 0.0 when the mixture is very lean. By connecting the sensor's output wire through a voltmeter to battery ground, we can use it to test for vacuum leaks. To do this:

  • Get the sensor HOT by driving the car.
  • Test the sensor's lean response by creating a massive vacuum leak. Disconnect the gray line at the back of the manifold, where you hooked up your vacuum gauge.
  • Test the sensor's rich response by spraying carb cleaner into the intake. (The air cleaner needs to be off for this work.)
  • If the sensor is not responding correctly, replace it. It is vital for proper mixture control and fuel economy.
  • If the sensor is working, test for vacuum leaks by spraying small amounts of carb cleaner around suspected leak areas, such as fuel injector seals and breath hoses. If you see a brief spike in the voltage, you've found a problem area.
  • Do not go crazy with the carb cleaner: it is hostile to old rubber.

Unfortunately, not all of the possible culprits can be reached with this procedure. The rubber "donuts" between the upper- and lower-halves of the intake manifold are almost impossible to test. But usually, some combination of this procedure plus temporarily isolating vacuum-powered accessories will expose the leak.

Finally, a word on a vacuum leak location that is easily overlooked, but which can be very serious if allowed to get too far. The vacuum line from the back of the intake plenum to the brake booster is critical for brake performance; these cars are very difficult to stop without servo assistance. The line itself is easy to inspect for cracks, but it's hard to verify the integrity of the check valve in the line. The valve can look fine from a distance, but hairline cracks may be developing right at that point where the thick tubing mates with the valve. Try flexing this area with the engine running and see if your id changes, and give it the carb cleaner spritz test, too. New lines, including the check valve, are $ 40-50 and worth replacing for peace of mind if the original is still on there. Do not ask me how I know …!

How to Use Eye Tracking Software to Test Your Website's Usability

Using eye tracking to understand the usability of user interfaces is something that's been around for a few years now, but it is still being understood by researchers. Through specialized eye tracking software, you can better see how users visually "enter" a website (or any graphical user interface), navigate the page, and where they focus. First I want to discuss the research and significance for eye-tracking software, then I want to discuss each of these elements in turn.

Research on eye tracking dates back to research on how people read pages in general. Early researchers found that – as common sense would implore – readers are attracted to certain visual stimuli, like bright colors or certain shapes and orientations. This is not too hard to imagine, as we all know our eyes tend to naturally float towards highlined areas on a page. However, these researchers also found that readers both see an entire page without really looking at it, and they also enter and visually navigate a page according to how they think the page should be laid out.

Seeing the entire page without really looking at it is important. It means that readers will get meta-information first and then begin to narrow down their visual selections according to that meta-information. Meta-information simply means that when users open a web page, without really even reading it, they will know where advertisements are located, where images and visuals are located, and where information and items relating to each other can be found.

As for the second part, users already have some idea of ​​what a page should look like as soon as they open it. They've been trained on certain things. For example, they usually know to find menus on the left or the top. They usually know that there will be an advertisement located along one or both of the sides of the page (as on this one).

The combination of these two things means that you should design a page so that it meets the user's expectations, and so that they quickly see what you want them to see. Now how do you find out what they're seeing?

Eye tracking applications, such as GazeTracker in association with ERICA (Eye-Gaze ​​Response Computer Aid), EyeLink 2000, or faceLab produce a log of where a user's gaze either moves or is sustained on a page. To understand what a user is fixing on, you need to understand where the user's gaze is sustained for a brief period of time. Those locations display what user's are paying attention to – reading or spending a moment to understand – on the page. Further, understanding the path of their gaze will help you understand how they are actually traveling on a page.

Once you've connected these tests (using task-based testing) you can use the results to orient information you want your user's to see. All in all, eye-tracking studies are one of the best measurements used for determining the usability of a website.

Things You Must Know About Teletracer Car Tracking Device

Many people have heard of the concept of a GPS surveillance gadget. GPS stands for global positioning devices that will identify your car's current location and reports can be accessed through the internet. For instance, if you have a GPS system made by Brickhouse Security, reports can be accessed using their Bolt Server. This type of device is different from Teletracer car tracking device. Teletracer tracking device will help you track down your car once your car has been stolen. This means that it serves as an anti-theft gadget for your vehicle. But you have to watch out for this product in terms of its price. This product is a bit expensive than others and will charge the owners with a subscription fee. The price of the product alone is around $ 600 and then to e followed by a monthly subscription fee. Your car equipped by this gadget can be tracked down by the police department within your area.

It's essential for you to create set up points where the permissions can receive the tracker's signal. Upon receiving the tracker's signals, they can go to the location where your car has been bought or hidden. Although this can be helpful within your police department's area, the problem comes when the Teletracer car tracking device is already out of your police department's coverage. Basically, car thieves will not only lurk within your area and once stolen, they may send out signals that are outside local police's covered area. Here, there's a limitation in terms of getting assistance for theft apart from the price being too much for your budget.

Using a Nano GPS tracking gadget, you can leave it inside your car's hidden location like inside a glove compartment. You can pay Brickhouse Security's Bolt Server to track down your vehicle and whereabouts. But just like Teletracer car tracking device, they charge monthly subscription fees but the difference comes in terms of the limitation when it comes to being detected by the local police. These gadgets are helpful in helping you track down your car for any theft incidents but you must know their pros and cons to find the most beneficial for you.

Wallet Safety: Protect Your Credit Cards From RFID Tracking Systems

Is it safe?

While RFID is gaining in popularity, and many companies are bidding to use it in all sorts of industries, from grocery scanning to tracking currency and retail, RFID technology can also pose a serious security hazard in credit cards. The technology Website EnGadget found that any unauthorized user can scan RFID credit cards for unencrypted data using a reader that can be purchased online for as low as $ 8.00.

How can I protect my wallet?

Credit card companies are catching on to the threats posed by RFID, and are taking action to boost security in the near future. If you are concerned about the safety of the information on your cards, here are some steps you can take right now to protect your credit cards from RFID tracking systems:

  1. When you are out and about, use cash or normal credit and debit cards. Leave your RFID cards at home and use them for online purchases only.
  2. Stack your RFID cards in your wallet back-to-back. This creates what is called "tag collision," essentially giving the reader too many signals to process at once. This offers little protection, however, since time read is very fast and it can be easy to develop systems that scan the chips one at a time.
  3. Get a DataSafe wallet, or other similar product approved by the Government Services Administration to block RFID signals. These wallets are indistinguishable from a normal wallet on the outside.
  4. Buy credit card shields to hold your cards when not in use. These are made from aluminum material and there are a number of companies that make them for less than $ 10.
  5. Go the homemade route: Wrap your RFID cards in aluminum foil before you put them in your wallet. Some users have said that this is a simple and effective way to block your cards from RFID readers.
  6. Make sure to consistently monitor your credit card statements, ad be on the alert for any suspicious account activity. Even if you do not have RFID cards, this is the best way to avoid credit card theft and fraud.

RFID technology at this point is limited to a range of about 5 feet. This may not be the case for long, however, as advances and new technologies arise, it will be increasingly important to secure anything containing personal information that is equipped with RFID or similar technology. Watch for advances in the technology and ensure your personal information is secure.
