Laser Detectors vs. Laser Transceivers

In any discussion of modern radar or laser detectors, the question of how to handle laser or Lidar speed measurement should be a fundamental and important aspect. More and more law enforcement agencies are switching to Lidar guns because they offer very precise speed measurements of a single vehicle, even at distances as far as 6,000 feet. An officer using a Lidar gun can measure the speed of your car, truck or SUV in as little as 0.3 seconds.

Portable Radar and Laser Detectors

When it comes to radar detectors, there are two basic options. Portable radar detectors mount to your windshield or rearview mirror and are often powered by a simple cigarette lighter plug. These all-in-one solutions do an excellent job of detecting long-range radar signals, thanks to their high mounting location on the vehicle. When it comes to Lidar guns, though, the best a portable radar detector can do is to advise you when it detects the laser beam.

What’s wrong with knowing that Lidar is being used? If the police officer was targeting your vehicle, he had the speed measurement before you could even put your foot on the brake pedal. Most radar detector users consider the laser detection system on a portable radar detector as an “I am about to get a ticket” warning.

Why do portable radar detector systems have Lidar detectors? The manufacturers hope that the system picks up a laser signal that has been reflected off a nearby vehicle. If you weren’t specifically targeted, this alert may be enough warning to let you slow down to a safe speed.

Custom-installed Radar Detectors

The other option for a radar detector system is one that is custom-installed in your vehicle. In this system, a dedicated radar receiver is mounted behind the plastic front bumper cover and in some vehicles, an extra radar receiver in the rear. Depending on the brand of the detector you purchase, a small display module may be mounted inside the vehicle, or you may have a simple warning LED or two and a speaker system that will alert you to what type of speed measurement system was detected. Custom-installed radar detectors use larger, higher-sensitivity radar receivers to provide excellent performance.

When it comes to Lidar, a custom-installed radar system can provide defense against laser speed measurements. Here’s why. Many systems include, or have the option to add, laser transceivers that mount in your front grille. In the same way that a portable radar detector includes laser detection, the custom-installed system also monitors the common laser wavelengths for signs of Lidar measurement.

Here is where things change dramatically. Once the system detects a Lidar signal, it immediately transmits random information on the same wavelength to confuse the Lidar gun. If your laser transceivers are installed and aligned properly, the police officer won’t be able to get a speed measurement from your vehicle.

There’s a Part 2 to this Story

If the laser transceiver system simply continued to confuse the officer, he or she will likely recognize what you are doing and may pull you over anyhow. To keep the peace, laser transceiver manufacturers suggest that you slow down to a legal speed, then cancel the laser transmission. This will allow the officer to take a speed measurement and you can carry on your merry way. In most systems, pressing a button on a small remote or control panel will cancel the laser signal transmission.

Lidar Transceiver System Options

Different manufacturers such as K40, Escort, Al Priority and Stinger each provide distinct laser transceiver solutions. The number of transceivers required for your vehicle depends on its size and design. In most applications, two transceivers on the front or rear of the car or truck will provide good coverage. If you have a larger vehicle, a third transceiver will increase the intensity and coverage of the modified laser signal.

What about DragonEye?

If there has to be a buzzword in the radar detector industry, it would be DragonEye. DragonEye Technology LLC is based in Georgia and is a manufacturer of Lidar speed measurement guns. Their speed measurement systems have proven to be difficult to confuse. Any discussion about what make and model of a laser defense system is capable of preventing a DragonEye gun from taking a measurement is often short-lived. New software updates for the guns are released on what seems like a regular basis. To keep up with this ever-changing technology, Lidar defense system manufacturers have to provide updates for their systems as well.

More important than being able to defend against DragonEye today is the knowledge that the manufacturer you have chosen will continue to provide updates as new Lidar gun firmware is released. Be sure to do your homework and ask your retailer about the frequency of updates, and how easy or complicated it is to install them on your system.

Drive Safely

We hope that this discussion of the difference between laser detection and laser defense systems helps you make an informed purchasing decision. If you do choose a custom-installed radar detector and laser countermeasure system, how the system is installed plays a significant role in how well it performs. Do your homework. Get references. Inspect the work the shop has done on other vehicles. An investment in a custom radar and laser system isn’t insignificant, so be sure it is done right the first time.

As always, the staff and editors at BestCarAudio.com hope that you always drive safely and responsibly. A radar detection and laser defense system isn’t a license to break the law. Stay in control of your vehicle at all times and drive according to the road and weather conditions. We want you as a reader for life.

Google’s Waze offers the Best in Navigation

It’s not often that a piece of software creates a significant impact on our daily lives. Milestone social media apps like Facebook and Twitter most certainly remain in the limelight, but when it comes to actually being productive, Waze is a major step forward in navigation apps for our smartphones. In the summer of 2017, Waze announced that it would include compatibility with Android Auto to make it, quite possibly, the best navigation solution for Android phone users to date.

What is Waze?

When Waze launched in 2006 it was called FreeMap Israel. It was a turn-by-turn navigation application for smartphone users. Fast forward to 2013: Waze won the prestigious Best Overall App award at the Mobile World Congress conference. In the same year, Waze was purchased by Google for an impressive $1 billion. Google knows the value of information better than almost any other company in the world, so its choice to invest in Waze makes sense.

Waze Map Updates

Waze differs from other navigation solutions in two very important ways. Users of Waze have the ability to update map information. If there is new construction in your neighborhood or a reconfiguration of a freeway onramp, you can update the map information in real time on your smartphone. That information will be integrated into the map database, and all other Waze users can continue to enjoy the latest mapping and navigation information without the need to wait for updates or downloads.

Historically, changes to map information could take anywhere from months to years to become available. While map companies like TomTom (formerly TeleAtlas) and HERE (formerly Navteq) do update their databases quite frequently, that new information takes time to trickle through the update process for portable and vehicle navigation systems. Waze is up-to-date within hours.

Real-time Traffic Information

The second key feature of Waze is its ability to share traffic flow information with fellow users. Waze is often referred to as a crowdsourced navigation solution, as users can report traffic jams, accidents, road closures and the presence of police. Within seconds of reporting an accident or a traffic jam, all your fellow Waze users receive that information.

Waze will consider traffic jams as it creates new routing plans. If you live in a major urban area that is prone to congestion, this information can prevent significant delays and help get you to your destination much faster.

Using Waze with Android Auto

As voice control is the key benefit of Android Auto, using Waze to plan your drive is easy. Initiate the voice recognition command, then simply ask for the destination or address you want, and include the word Waze at the end of the address. Android Auto will launch Waze and calculate your route.

The Waze interface on Android Auto is very similar to what you would see while using it on your smartphone. The fonts on the screen are nice and large, and accessing route-planning options like avoiding toll roads or picking a different route are easy to get to. Many users report that Waze is, in fact, easier to configure than Google Maps.

Reporting Information

As we mentioned, a key feature of Waze is the ability to report information to other users. Tapping the Listen button will let you report traffic jams, accidents, bad weather, road closures, and more by talking to the system. You can say, “Report a traffic jam,” and Waze will ask you how bad it is. You can share the location of hidden or visible police or let your fellow Wazers know there is a pothole or ice on the road.

As users approach the location where you have provided information, they will see an alert on their screen. In the case of obstacles and police, your fellow users can also report that the obstacle has been cleared. It’s all simple, quick and easy – just like Android Auto itself.

The Navigation Experience

Of course, Waze includes full turn-by-turn navigation prompting and will read out street and freeway names. You get lots of warning to let you know what maneuver is coming up next to reduce the need for sudden lane changes that can endanger you and your fellow drivers.

When you plan a route with Waze, you have the option of choosing from three different routes. Waze displays obstacle icons along a bar and the associated travel time and distance for each route. Choosing the best path is quick, easy and efficient.

If Waze is alerted to a traffic jam along your route, it will provide you with a prompt that suggests a new route and the new travel time and estimated time of arrival. You can, of course, choose to ignore that advice, but we recommend you don’t.

Another cool feature of Waze is that it will notify you of obstacles, even without a route planned. If you are driving along and someone has reported a pothole or hidden police officer, the notification appears just the same.

Is There a Downside to Waze?

Do silver linings always have a dark cloud? Maybe, maybe not. There is one limitation to Waze that is a bit of an annoyance. You can only plan routes that are less than 1,000 miles. If you are in San Francisco and want to go to Niagara Falls, you can’t plan a single route. You need to choose a destination within 1,000 miles, then plan another 1,000 miles from that point. What’s more frustrating, Google Maps CAN plot that route. Waze provides a message that they are “working to increase that distance,” but that’s been a limitation for a long time.

The other thing about Waze is advertisements. We all know that Google loves to sell advertising. Companies like McDonald’s, Whole Foods and Taco Bell all pay for pop-up ads that are displayed when you are using Waze on your smartphone. Good news, though: These advertisements aren’t currently displayed when you are using Waze with Android Auto. That would be contradictory to the philosophy of reducing driver distractions.

Check out Android Auto and Waze Today

If your car, truck or SUV came with Android Auto, then check out Waze next time you are in the car. If you don’t have an Android Auto-equipped radio, drop into your local mobile enhancement retailer and ask if there is a solution for your vehicle. Android Auto and CarPlay are amazing products, and can not only make your time behind the wheel much safer but also more productive.

Will Upgrading My Speakers Make My Stereo Sound Better?

When it comes to reproducing an audio signal, your speakers are the most important component in the food chain. You could have the best source unit and amplifiers known to man, but if your speakers are mediocre, then the listening experience will suffer. That said, the world of car audio has changed over the years. With all of the changes in new cars lately, a question that often comes up is “Will upgrading my speakers make my stereo sound better?”.

Factory Audio Complexities

Spurred by the efforts of companies like Harman and Bose, factory audio systems sound better than ever. Does that mean they sound great? Not necessarily. OEM audio systems have amazing technologies and elaborate tuning, but they are often missing a crucial component – excellent speakers. Why go to all that trouble and not use the best speakers possible? In most cases, the answer is cost. Building an inexpensive speaker may cost $20 or $30. Building one that is “really good” can cost more than 10 times as much, and it goes up from there. These prices don’t include packaging, shipping, marketing, training or warranty costs. When you consider that most cars with premium sound systems have somewhere between 12 and 20 speakers, with a few having more than 30, implementing truly excellent speakers would have a dramatic effect on the final cost of the vehicle.

How About Just Upgrading My Speakers?

If you had a high-end, two-channel home audio system, upgrading your speakers would be one of the easiest ways to improve the clarity, detail and accuracy of your audio system. If you have a simple stereo system in your car, the same philosophy holds true.

There is a problem, though. More and more factory audio systems, even systems without elaborate amplifiers, include signal processing to make the inexpensive speakers they use sound better. Let’s look at an example.

Chrysler is well known for its use of a woofer in the front door of its vehicles and a small midrange driver on the dash. In most applications, this midrange driver has no tweeter. The amplifier in the car or truck is tuned to increase the high-frequency information sent to that speaker. The result is that you hear high-frequency content in a relatively good balance with the midrange information.

Let’s say we upgrade those dash speakers with a good quality midrange speaker with a coaxial tweeter. The high-frequency signal boost from the amplifier or source unit now results in far too much treble information in the system. Yes, we upgraded the speakers, but now the system sounds worse. In fact, it may be unlistenable.

The same issue exists with any speaker we want to upgrade. Adding a subwoofer, better door speakers or new speakers in the back of the car can all result in a system that doesn’t sound as good as the factory system. Every speaker has different efficiencies, frequency response characteristics and frequency limits. Assuming you can swap one for another will lead to problems.

How Do We Upgrade Our Sound Systems?

Without getting into the complexities of sound systems with upmixers and other elaborate processing, the simplest method of upgrading is to include a digital signal processor and amplifier into the system. Here’s how this works.

Your mobile electronics retailer will install a digital signal processor, a new amplifier and your new speakers. He or she can then measure the output of each new speaker using a real-time analyzer and adjust the processor it so that it produces smooth and natural frequency response. The process should take just an hour or two, but it results in a significant improvement how the system sounds. Proper tuning is as important as the choice of speakers and their installation.

With most DSP units on the market, the tuning process can improve the frequency response of the system – and where the sound comes from. Ensuring that both left and right speakers sound the same at the listening position is crucial to creating the feeling that your music is coming from a soundstage right in front of you.

It’s Not Just Your Stereo

Your speakers are not the only part of your vehicle that has become more complicated to upgrade. Decades ago, a set of headers and a large diameter, free-flowing exhaust could unleash a noticeable increase in performance. Your mechanic could fine-tune a carburetor to increase engine performance based on the efficiency improvements you chose.

With modern computer-controlled engine management systems, you can’t change anything. If you decide to modify the intake or exhaust, the computer may not like the changes and turn on a Check Engine light. The solution? A programmer can be purchased to recalibrate the engine management system for the modifications you have made. Do you see the parallels?

Upgrade for Better Sound

The answer to the question of whether upgrading your speakers will make your stereo sound better is a resounding yes. But the overall system design needs to be taken into consideration for the upgrade to be successful.

If you’re on the fence about upgrading your audio system, drop into your local mobile electronics retailer and listen to their demo vehicle or a set of high-end speakers on their display board. Ask if they can demonstrate how digital signal processing can improve the performance of a mobile sound system. Once you’ve heard how amazing a well-installed and properly tuned car stereo can sound, we think you’ll be hooked.

Product Spotlight: Momento M7 Dash Camera

Protecting yourself against fraud and false accusations while driving is easier when you have a dashcam system installed in your car or truck. Momento, the collision avoidance and safety technology brand from Firstech, has just introduced a new and revolutionary video recording solution – the M7, also known as the MD-7200. This new dash camera system increases the camera’s recording resolution, adds support for up to two additional cameras, and includes a unique radar-based motion sensor for parking mode.

Dashcam Video Features

The M7 is a super-compact dashcam system with a body measuring just over 2 inches wide, 1.5 inches tall and a mere 1.14 inches deep. The camera includes a windshield mounting bracket with the power, rear camera and interior camera connections built in for a tidy installation. The GPS receiver is also built into the base to have a clear view of the sky to provide as much accuracy as possible.

A compact color LCD touchscreen is on the rear of the body. Your installer can configure the camera settings quickly and easily through the menu, and you can view videos right in the vehicle without needing a computer or smartphone.

The integrated forward-facing camera features a QHD (Quad HD) 2560-by-1440-pixel image sensor. That’s an increase in detail of 1.78 times what’s offered by 1080p sensors. As we’ve mentioned numerous times, image sensor resolution is crucial for capturing vital information like license plates and other identifying marks. Low-light and high-contrast video performance are a key part of what separates good cameras from great ones. The 5-megapixel image sensor in the M7 benefits from class-leading light sensitivity, exceptional noise reduction in dark conditions and seamless dual-exposure HDR to ensure that every detail is captured with the utmost clarity. It’s designed around a native 16:9 aspect ratio.

A key feature of the M7 is that the system comes out of the box with a high-performance rear camera. Many competing solutions have secondary cameras as an optional upgrade. Momento felt it was just as important to capture what was happening behind the vehicle as in front. The rear camera has a 1080p sensor, and the mounting bracket can be adjusted for perfect coverage out the back window of a sedan, hatchback, SUV or pickup truck.

The optional IC6 (known formally as the MD-IC6) vehicle interior camera is also 1080p and includes infrared emitters so everyone and everything inside the vehicle will be visible in the recording, even when it’s dark.

Finally, the M7 system includes a 64 GB microSD memory card, so there’s nothing extra required before your installer gets to work. Of course, a power harness is also included, so your installer can wire the camera system into the power and ignition sources for seamless operation.

Eco Mode Parking

Most modern dashcams have a function called Parking Mode. When the camera system is stationary for a short time (usually a few minutes), it stops storing video on the memory card. Most cameras continue to monitor what’s happening around the vehicle, and then they store a video file when the image sensor detects that someone or something has moved. Parking mode operating requires roughly 240 to 250 milliamps of current draw from the vehicle battery. This amount of current can drain the battery significantly after just a day or two.

The new Momento M7’s Eco Mode doesn’t use the image sensor to monitor motion. Instead, the M7 has a built-in radar sensor, as you’d find in a commercial building security system. When the radar sensor detects motion, the M7 starts to store video again. The benefit of this design is that the radar sensor motion detector draws less than 30 milliamps of current. Unless someone is circling your car constantly, that’s a massive reduction in current consumption that translates into less draw from the vehicle battery.

Just as with Momento’s previous flagship dashcam, the M6 or MD-6200, during regular driving, the integrated accelerometer can trigger an alert recording that captures 15 seconds before the trigger and 15 seconds after. In addition, you can start a manual event recording by tapping on the REC button in the lower right corner of the touchscreen should you witness something abnormal during your driving adventures.

Easy-to-Use Desktop Software

You can download the M7 PC or Apple viewing software directly from the Momento website to easily navigate videos stored on the card with your desktop computer. The software will also allow you to view the front, rear or interior video feeds along with vehicle speed and location information. The location information is overlaid onto Google Maps data to see exactly where the vehicle was headed. Finally, data from the three-axis accelerometer is also shown on the screen, so braking, sudden steering inputs or an impact are also visible.

Upgrade Your Protection with the Momento M7 Dashcam

If you’re looking for a premium dash camera system with a high-resolution image sensor, support for multiple cameras and the latest in power-saving parking mode monitoring, visit a local authorized Momento retailer and ask about the new M7 dual-camera dashcam with radar. You can find a retailer near to you using the online dealer locator on their website. Also, be sure to follow Momento on Facebook, Instagram and to keep up with their latest news and product releases.

10 Things You Didn’t Know You Could Do with a Remote Car Starter

With summer coming to an end and frost in the forecast, there’s no better time to add a remote starter to your car, truck or SUV. Most of us know that our remote starter systems can also control the power locks in our vehicles, but many systems are full of additional advanced features that add convenience and improved comfort to our vehicles. Let’s look at 10 things you may not know your remote starter can do.

Before we dive in, we should let you know that the functions we are going to describe are dependent on the model of remote starter you choose, the remote you choose and the vehicle you own. Talk to your local mobile enhancement retailer about these options and any associated costs.

1. Rear Window Defroster Activation

You may know about this one, since it is probably the number-one option people add to their remote starter systems. If the interior of your vehicle is below a certain predetermined temperature when the car is remote started, the remote starter system can automatically activate the rear window defroster to help you see clearly when it is time to go. Even a few minutes of warm-up time can make clearing the rear window quick and easy before you get in the car. Likewise, some cars have sideview mirror defrosters tied to the rear window heating system for added convenience.

2. Trunk/Hatch Release

Trunk or hatch release from a multi-button remote isn’t all that exciting, but it sure is convenient. If your vehicle doesn’t happen to have a trunk release button, ask your retailer about adding a solenoid. Yep, they can add the power trunk function to most vehicles.

3. Remote Start Your Car from Your Phone or Apple Watch

Several different options for telematics systems use an application on your iPhone or Android phone to lock, unlock and remote start your vehicle. Several of these apps are compatible with the Apple Watch, so you can press a button on your wrist to warm up your vehicle.

4. Start Automatically When the Weather is Cold or Hot

Many remote starter systems can be programmed to start automatically when the internal vehicle temperature drops below or rises above a predetermined temperature. Temperature start will ensure the temperature does not get too extreme.

5. Start Every Few Hours or Daily

Some systems offer the ability to start every few hours. When the temperature outside is frigidly cold, keeping some warmth in the engine, fuel system and coolant is useful. You can toggle this function from most remote controls.

6. Protect Your Vehicle

A remote starter system can often be upgraded with security system functions. Starter kill, a siren and a multi-stage shock sensor help to ensure that would-be thieves are sent packing if they start messing with your vehicle. If you have a two-way remote control or a smartphone telematics system, you will be alerted as soon as the alarm goes off.

7. Control Power Sliding Doors

If you drive a van with motorized sliding side doors, your mobile enhancement retailed can often add control for those into your remote started. Most system includes one or two auxiliary outputs that can be used to open or close doors or power tailgates.

8. Control Power Windows and Sunroof

Remote starters are just as useful when the weather is hot as they are when it’s cold. In many applications, we can add a module that allows you to roll your windows up or down, and open or close your sunroof. Imagine arriving at your destination with your windows down and sunroof open. You get out of the vehicle and start walking away. When you press the lock button on your remote, all the windows roll up, and the sunroof closes automatically. It’s not only a convenient feature, but it’s kinda cool, too!

9. Control Multiple Vehicles

If there are two vehicles in your family with similar remote starter systems, you can often control both from a single remote control. Depending on your remote, you can toggle between vehicles, or control the second vehicle using an extra button press before the function you want to activate.

10. Extend the Life of Your Engine

Perhaps this should be the first item, because it’s one of the most important features a remote starter offers. Most people think they are buying a remote starter to make the vehicle more comfortable for them. While this is true, letting your engine warm up before you start driving can extend its life dramatically.

The oil in your engine is responsible for preventing metal-on-metal contact. When the engine is cold, the oil is thicker and has a harder time flowing. If you start your car and start driving right away, the oil may not be able to protect the engine. Even 2 minutes of warm-up time when it’s 40 degrees out can help warm up the oil and get it flowing. (Always be gentle on the gas until the engine has warmed up fully – remote started or not.)

Remote Car Starters Add Convenience

Even if you just want a head start on warming up your vehicle, a remote car starter is an excellent way to save time and improve your comfort. Talk to your local mobile enhancement retailer about the options that are available for your vehicle.
