Product Spotlight: Thinkware U1000 Plus Dash Camera

If you are shopping for a premium dash camera with a high-resolution image sensor, the Thinkware U1000 Plus should be on your shortlist. This solution can record video in 4K resolution and is available with a secondary camera to capture what happens behind your vehicle. Let’s take a close look.

Design of the Thinkware U1000 Plus Dash Camera

The U1000 Plus is a low-profile camera that mounts at the top of your windshield. Rather than a square or round body, the bulk of the camera sits flat against the glass. This design leaves a lot of clearance for the sun visor and rearview mirror.

The main camera can be tilted up or down to ensure the system works with windshields with varying rakes. The camera body is 4.33 inches tall, 2.55 inches wide and 1.18 inches thick. On the left side of the chassis are power connections, a port for an external radar sensor and the optional rear camera. The rear camera uses a USB connection, so you shouldn’t have issues with RF interference. Thinkware includes a hardwire installation kit with the camera. You can upgrade to the OBD-II power cable if you don’t want any of the wiring in your vehicle modified. This is a wise investment for leased vehicles.

Thinkware U1000 Plus — The right side of the chassis has the Micro SD memory card slot, the reset button and the microphone.

Once installed, the camera body has the manual recording button in the center and the Power, Wi-Fi and voice recording buttons in the upper left corner. LEDs across the top indicate when the unit is on, when Wi-Fi is enabled, and when the GPS receiver has locked on enough satellites to pinpoint your location.

Thinkware Dash Camera Specifications

This camera features a Sony IMX515 STARVIS-Series image sensor that can record at up to 3840 x 2160 pixels at 30 frames per second. It can also be configured to record in 2K mode at 2560 x 1440 pixels at 60 frames per second. The viewing angle is rated at 135.6 degrees, offering a good balance of detail and field of vision.

The rear camera features a Full HD-quality image sensor that records 1920×1080 pixels at 30 frames per second. Both the front and rear cameras have a High Dynamic Range (HDR) mode that compresses the light and dark parts of the image to make objects in shadows, or that might be washed out by a bright light source more visible. Low-light performance is further enhanced with Thinkware’s Super Night Vision 3.0. This processing reduces noise when light levels are low to keep videos clear and sharp.

Video files are stored using the HEVC format H.265 to maximize file storage. With the 64GB card included, the system can store up to 151 minutes of video in a dual-camera solution. You can increase the size of the memory card to 512 GB for an incredible 1229 minutes of storage.

You can upgrade the U1000 Plus to a five-camera system using Thinkware’s optional multiplexer and three additional cameras. This is an ideal solution for taxi, limousine and rideshare applications.

Parking Mode Protection

The Thinkware U1000 Plus includes several parking mode options. In energy-saving mode, the camera only stores video when the onboard accelerometer detects impacts. Motion and Impact mode allows the camera to watch for vehicles or people entering the field of vision along with impact sensing. The camera stores a 20-second video that starts 10 seconds before the event trigger. Time Lapse mode records constantly at two frames per second.

The U1000 Plus can be upgraded with Thinkware’s optional radar module. Rather than monitoring the area in front of the vehicle using the image sensor, the radar sensor detects someone or something approaching. This dramatically reduces current consumption, so there is less draw on the vehicle battery.

Wi-Fi Connectivity

You can use the Thinkware Dashcam Link app on your Android smartphone, iPhone, or tablet to view video files stored on the system. Once connected, your installer can adjust the system settings and fine-tune the viewing angle to ensure maximum coverage.

The Thinkware Connected app gives the U1000 Plus Cloud-based connectivity. If you have a mobile hotspot, or the dashcam can connect to Wi-Fi at your home, you can view what the camera sees on your phone. You’ll also get impact notifications when parked. The vehicle operator can send an emergency message to the registered contact by pressing the REC button on the chassis for three seconds. Parents or business owners can review the vehicle’s operational history to review use and driving behavior.

Advanced Driver Assistance Systems

Modern video processing technology allows the U1000 Plus to warn the operating. These Advanced Driver Assistance Systems (ADAS) include Front Vehicle Departure Warnings (FVDW), Forward Collision Warnings (FCWS) and Lane Departure Warnings (LDWS). Notifications about approaching a vehicle too quickly or crossing the lines on the side of the road can help prevent serious accidents.

Upgrade Your Vehicle with a Thinkware Dash Camera

We all know that having a dash camera is the best way to protect yourself from fraud and false accusations. It’s also an ideal solution for capturing those “I can’t believe that just happened” moments. When upgrading your vehicle, drop by a local authorized Thinkware retailer and ask about the U1000 Plus system. They can provide you with a quote that includes expert installation.

You can learn more about Thinkware products like the U1000 Plus by visiting their website. Their dealer locator makes it easy to find a retailer near you to help design and install a premium dash camera system.

Product Spotlight: Rockford Fosgate PP4-NT

Not long ago, we took a look at the impressive PPS4-10 10-inch Punch Pro midrange drivers from Rockford Fosgate. While they are great for keeping up with a trunk full of subwoofers, what works in terms of reproducing those high frequencies? This spotlight focuses on the Rockford Fosgate PP4-NT Punch Pro tweeter. Let’s check it out!

Rockford Fosgate PP4-NT Specifications

The PP4-NT is a one-inch diameter aluminum dome horn tweeter designed for SPL systems. The tweeter is rated to handle 50 watts of power continuously and 100 watts maximum. The driver has a nominal impedance of four ohms and has an incredible efficiency rating of 105 dB SPL when powered with one watt and measured at a distance of one meter.

The Rockford Fosgate PP4-NT tweeters are sold individually. So, if you need a pair, then you have to buy two of them.

Punch Pro Tweeter Features

As mentioned, the PP4-NT is based around an aluminum diaphragm and is powered by a compact neodymium magnet. The voice coil is formed from high-temperature Nomex to help ensure reliability. This is all housed in an aluminum chassis that improves heat extraction from the voice coil assembly. To increase efficiency, the tweeter uses a horn design with a pointed phase plug.

Electrical connections are handled by a pair of spring-loaded chrome terminals on the bottom of the housing. The terminals are designed to allow wires to be inserted from underneath the tweeter, preventing wires from protruding and increasing the overall size.

SPL Tweeter Mounting Options

Rockford Fosgate includes two mounting solutions for the PP4-NT. If space is at a premium, then the compact outer trim ring will screw down into the body and clamp over materials up to 0.35 inches thick. Your installation technician will need access to the back of the mounting location to complete this installation.

Alternatively, the tweeter can be flush mounted through a 2.52-inch hole using the provided removable mounting flange.

With the compact mounting ring, the tweeter body is 2.52 inches in diameter and the ring is 2.09 inches across. The surface mounting ring measures 3.64 inches across.

Crossover Options

The PP4-NT includes a built-in 6dB/octave 4kHz crossover. This is equivalent to using a four-microfarad capacitor wired in series with the voice coil. You can also use the tweeter with the PP4-X Punch Pro passive crossovers. The crossovers are designed to apply a 3 kHz low-pass filter to whatever four-ohm Punch Pro midrange you choose. They also add 0, -3 and -6 dB output attenuation options for the tweeters. If you don’t have a DSP and amplifier channels dedicated to the tweeters, then the PPS-X crossovers are a wise investment.

Louder Than Loud for Music Fanatics

If you are working on building a car audio system designed to play music at rock concert levels, visit a local authorized Rockford Fosgate retailer and ask about the PP4-NT tweeters and the rest of the Punch Pro line.

You can find a local authorized Rockford Fosgate retailer at their Dealer Locator. Be sure to follow Rockford Fosgate on Facebook, Instagram and YouTube to learn about their new products and the amazing events they attend each year.

Definitions: Speaker Parameters

The adage that someone could write a book about a subject certainly holds true when it comes to a discussion of loudspeakers and their parameters. In fact, there are dozens of great books already available about the subject. This article provides an overview of some of the most commonly discussed speaker parameters.

What are Speaker Parameters?

Speaker parameters, often called Thiele/Small parameters, are a set of electromechanical measurements that can be used to define the low-frequency performance of a transducer. Using these parameters and a series of calculations, your installer can predict the performance of that speaker in an enclosure.

What Can We Determine from these Parameters?

Perhaps the most important set of calculations we can create is the output of the system. When we discuss the “system,” we are referring to the speaker itself and the enclosure in which we intend to install the speaker. Every speaker enclosure acts as a high-pass filter and reduces the low-frequency output of the driver. We gain physical power handling in return for this diminished output. Using a set of calculations, we can predict how much low-frequency information the system will produce.

Another important calculation is power handling. As mentioned, we need to control the movement of the speaker cone to prevent distortion and damage. We can predict how much the cone will move for a given amount of power in our test enclosure.

Resonant Frequency of the Speaker – Fs

In terms of analyzing the moving parts of the speaker, we need to know the frequency at which the compliance (springiness) of the spider and the surround combine with the mass of the cone and dust cap to store the most energy. At this frequency, the system alternately stores and subsequently releases the most energy for a given voltage input. If you were to swing a weight on a string suspended from the ceiling, the natural frequency at which it oscillates back and force would be equal to the resonant frequency of a loudspeaker.

Equivalent Compliance Volume – Vas

To understand how stiff the spider and the surround are, we compare them to an amount of air that would exert the same resistance to motion. Because air is easily compressed, a high Vas specification would represent a very softly suspended cone. Conversely, a speaker with a low Vas would have a very stiff suspension.

Electrical Q of the Driver at Fs – Qes

Understanding the Q (Quality Factor) can be somewhat difficult because it is a dimension-less value. In essence, the Q factor describes the damping characteristic of a resonant system. A higher Q represents less energy loss relative to the total energy stored in a system. A pendulum suspended from a low-friction bearing will have a high Q. That same pendulum, submerged in water, will have a much lower Q. An important consideration is that high-Q systems have less damping and, therefore, vibrate longer. The Electrical Q specification describes how much damping the voice coil and magnet assembly invoke on the moving cone.

As the voice coil moves past the magnet, it produces an electrical current. This current reaches its peak value at the resonant frequency of the driver and counteracts the current being provided by the amplifier. The net result is a significant rise in impedance at the resonant frequency.

Mechanical Q of the Driver at Fs – Qms

Just as the electrical characteristics of a speaker cause an opposition to cone motion, we have a similar effect from the mechanical properties of the speaker. Qms describes the mechanical losses resulting from the spider and the surround. A high Qms value describes lower mechanical losses, while a low Qms value describes higher losses.

Total System Q at Fs – Qts

This unit-less measurement is a mathematical combination of the mechanical and electrical characteristics of the speaker. In simple terms, we calculate Qts by dividing the total stored energy of the speaker by the dissipated energy in the speaker at resonance.

Compliance of the Driver Suspension – Cms

The Cms specification describes the stiffness of the driver suspension in meters per newton. A stiffer suspension will move less distance for a given amount of force applied to it.

Effective Cone Area of the Driver – Sd

This parameter describes the effective “size” of our speaker. We all realize that the cone will move air for us, but we also have to take into account the addition of the surround. It is commonly accepted that we can use a value of half the surround as contributing to the output of the driver.

Mass of the Cone and Moving Parts – Mms

The Mms specification describes the mass of the speaker cone and part of the spider and surround. Unlike the Mmd specification, Mms includes the acoustic load caused by the air in contact with the cone. In most cases, the values are similar, but as the surface area of the cone increases, so too does the value of Mms, relative to Mmd.

Maximum Excursion Level – Xmax

This parameter is frequently misinterpreted as being the defining factor in the distance a speaker cone can move. Early calculations used a formula that subtracted the height of the voice coil winding from the height of the magnetic gap, then divided by 2. This calculation describes how far the speaker can move before the winding comes out of the gap.

Subsequent investigation shows that non-linear behavior elsewhere in the driver design could have a larger influence on the motion limits of the cone. This suggests that Xmax should be the one-way excursion distance that represents a distortion level of 10%. This performance-oriented specification is far more indicative of the useful operating range of a driver, but is much harder to ascertain.

Additional Parameters

In this article, we only describe the basic parameters that are commonly used in predicting the low-frequency performance of a loudspeaker. Other parameters, such as inductance, become more relevant at higher frequencies. Addition parameters such as Nominal Impedance (Znom), efficiency, sensitivity and the Efficiency Bandwidth Product (EBF) are derived through equations that use the specifications above.

Proper Design Requires Simulation

A woofer in an over-sized enclosure may bottom out and be damaged easily. A midrange driver crammed into a small speaker pod may have a significant frequency response spike and an associated distortion peak. The result is quite unfavorable.

Before you assume a subwoofer or speaker is suitable for the enclosure or mounting location you have chosen, it is worth asking your mobile electronics retailer to perform a simulation to ensure everything will function the way you want. They can work with you to ensure everything will perform optimally, and your system will sound great!

Product Spotlight: Rockford Fosgate PPS4-10

What do you do when you need midrange speakers capable of keeping up with a pair of 15-inch Power Series subwoofers in the back of your SUV? The answer is the Rockford Fosgate PPS4-10 Punch Pro 10-inch speaker. These beasts boast a subwoofer-sized voice coil and handle 350 watts of power to ensure every word remains clear and audible over all that bass. Let’s dive into the details!

Rockford Fosgate Punch Pro PPS4-10 Features

The PPS4-10 is a high-efficiency midrange speaker with a massive 10-inch size. Sold individually, these speakers achieve an impressive efficiency of 96 dB SPL with just one watt of power measured at one meter. Each speaker includes a sturdy mesh grille for added protection in indoor installations.

Built on a stamped steel chassis, the PPS4-10 features a large 8.25 by 1-inch ceramic magnet. The basket uses the StampCast design, which provides the structural rigidity and provides the sleek look of a cast-aluminum design. Additionally, the mounting flange includes four slotted holes, allowing precise alignment during installation. Despite its large diameter, the speaker requires only 4.06 inches of mounting depth.

Rockford Fosgate PPS4-10 — The PPS4-10 features a massive 8.25 by 1-inch magnet to maximize efficiency.

Punch Pro Midrange Soft Parts

The speaker’s cone is made from fiber-reinforced pressed paper, keeping the cone mass low to help the speaker’s efficiency. A treated textile W-shaped surround connects the cone to the basket, while a high-temperature 2.58-inch aluminum voice coil sits at the core, topped by a machined aluminum phase plug. Beneath the cone, a poly-cotton spider delivers excellent control and durability.

For electrical connections, the PPS4-10 uses spring-loaded terminals mounted on the basket. Fatigue-resistant tinsel leads, sewn to the spider, prevent noise at high power levels.

Rockford Fosgate PPS3-10 — The lightweight cone is made from pressed paper to deliver excellent efficiency.

PPS4-10 Specifications and Application

The PPS4-10 has a resonant frequency (Fs) of 53.5 Hz, an equivalent compliance (Vas) of 1.24 cubic feet, and a total Q (Qts) of 0.26. With a maximum one-way excursion (Xmax) of 4.6 mm, it offers impressive performance for a midrange speaker.

To explore potential applications, we conducted simulations based on an estimated effective cone area for the PPS4-10. In infinite baffle setups, the mids perform with a -3 dB frequency of around 200 Hz.

Each speaker requires a minimum of 0.2 cubic feet of airspace for sealed enclosures. This setup delivers a -3 dB frequency just above 160 Hz. To bridge the frequency gap between these mids and a subwoofer, consider a woofer like the Prime R2 or Punch P1, which can comfortably play up to 150 Hz.

If you need the mids to handle lower frequencies, your installer can build a vented enclosure with a net volume of 0.25 cubic feet with a vent tuning frequency of 80 Hz. This configuration extends the output to just under 100 Hz. Unless you run massive, heavy subwoofers, you should be able to use a high-pass crossover at 100 Hz and still have the system sound dynamic and punchy.

Rock Out with the Rockford Fosgate Punch Pro Mids!

If you need midrange speakers to keep up with a wall of subwoofers, the Punch Pro series, including the PPS4-10, is an excellent choice. The Punch Pro lineup also features 6.5-inch and 8-inch mids to accommodate different installation spaces. All three sizes are available in four-ohm configurations.

The Benefits of Custom-installed Radar Detectors

If you are looking for the best defense against police laser and radar guns, speed cameras, and radar-based work zone speed detection systems, then a custom-installed radar detector and laser countermeasure system is the only choice. This article compares the features and performance benefits of a portable radar detection system to one that we integrate into your vehicle.

What is a Radar Detector?

Simply put, a radar detector is a device that includes one or more radio frequency receivers and a computer. The receiver is designed to focus on specific frequencies and report the presence of those signals to the vehicle operator. The goal of the system is to detect radar measurement signals used on vehicles in front of you and provide enough warning so you can slow down to a legal speed and avoid getting a ticket.

Law enforcement agencies in North America use three radar frequencies. X-band operates between 10.5 and 10.55 GHz, K-band operates between 24.05 and 24.25 GHz, and Ka-band operates between 33.4 and 36 GHz.

Why Custom-installed Radar Systems Offer Better Protection

When comparing portable radar detectors to custom-installed systems, the biggest performance benefit comes from the ability to make the radar receiver larger. As with any antenna, more size means more sensitivity. The radar receiver included with a custom-installed detector is typically bigger than an entire portable radar detection device. In AM/FM antennae, a half-wave antenna offers more than twice the sensitivity of a quarter-wave antenna. The benefit to you is that a custom-installed radar detection system can detect weaker signals and provide an earlier warning so you can slow down sooner.

Some systems include separate receivers and amplifiers for the low-frequency X-band and the higher K- and Ka-bands. This configuration allows each antenna to be more sensitive within its specified operating range and requires less signal filtering and amplification.

Many radar systems that integrate with your vehicle include a second high-sensitivity detector for the rear of the car or truck. Many police forces use dash-mounted radar systems that function while the police vehicle is in motion. If an officer is following you, you will want to know if he or she is measuring your vehicle’s speed.

Police Laser and Lidar Systems

Many law enforcement agencies now use laser-based measurement systems. These devices send out a very narrow beam of invisible “light” that pulses in a particular pattern. The laser gun measures how that beam is reflected to calculate the speed of the vehicle it is measuring. The laser works with incredible accuracy. High-quality laser speed detection systems have a beam width of only 30 inches at a range of 1,000 feet and can operate up to 6,000 feet away. They are accurate to within 1 mph and can acquire a reading in as little as 0.33 seconds.

Laser detection systems look for energy between 830 and 945 nanometers and report it to the driver. The problem with laser speed detection is that once the officer has pulled the trigger, he has an accurate reading of your speed. There isn’t any point in slowing down.

Laser Detection versus Laser Defense Systems

A premium portable radar and laser detector that mounts to your windshield can alert you to the use of laser speed measurement. As we mentioned, though, once the officer has a reading, it is too late. Your only hope of avoiding a ticket is to detect beam scatter from another vehicle, then slow down before the police measure your speed.

The number one benefit of a remote mounted detection system is its ability to combat laser or lidar systems. In a laser countermeasure system, there are several compact transceivers mounted near your license plate and headlights – the most frequent target for police radar. When these sensors detect a laser measurement signal, they instantly start to transmit a signal to confuse the radar gun.

The second issue with portable radar and laser detection systems is location. As we mentioned, police target your license plate and headlights because these are reflective, in hopes of getting an accurate reading at long distances. Your portable detector, mounted up high on your windshield, may offer excellent radar detection range, but can miss laser signals altogether due to that height.

Some custom installed radar detectors include laser functionality, and some provide it as an option. Talk to your retailer to ensure you are getting the protection you want.

How to Use a Laser Defense System

If a police officer targets your vehicle with his laser gun and pulls the trigger, he will be expecting a result almost instantly. If your laser defense system prevents him from getting a reading, the officer will quickly realize you are using a countermeasure system. To prevent him from following you for the next 10 miles or until you do something wrong, there is a suggested etiquette to using laser defense.

As soon as your laser detection system alerts you to the use of a radar gun, slow down quickly. Obviously, slamming on the brakes will attract attention. Smooth and steady deceleration is the ideal. As soon as you are at a legal speed, cancel the laser countermeasure system and let the officer take a reading. If that is executed smoothly, the officer will leave you alone and move on to measuring the vehicle behind you.

The only defense against police laser/lidar is a custom-installed laser countermeasure system.

Reduce the Clutter

If you are like us, then you hate clutter in your vehicle. There are some nice mounting brackets for portable radar detections, but they still detract from the appearance of your vehicle. Depending on the brand of custom-installed radar detection systems, there may be a small control panel that we can mold into your dash or center console, or no visible control panel at all. In these “invisible” systems, all of the alerts are handled with audible warnings and a pair of small LEDs. Eliminating connections to your cigarette lighter plug and suction cup marks on your windshield keeps your vehicle looking organized and tidy.

From a safety perspective, having a radar detector on your windshield will block some of your vision. The percentage of windshield area that a portable radar detector takes up is small, but every square inch counts when it comes to safe driving.

Protection against Theft

Dash and windshield mounted radar detectors are prime targets for thieves. The complexity and distributed design of custom-installed radar detectors make them too much hassle to steal. Even if thieves were to break into your vehicle, they would only be able to get a few parts of the system. The result is that there is no resale value, so they leave these systems alone.

Complete Vehicle Integration

Depending on the features and complexity of a remote-mount radar detector system, there could be as few as three components, or more than a dozen modules and sensors. We mount each component in a location that ensures reliable operation and protection against damage. We route the system wiring with factory harnesses and protect it with split loom or cloth tape – whichever best matches the OEM style of your vehicle. We make the electrical connections mechanically and electrically secure so they will function flawlessly for years.

When we install a radar detector and laser defense system in your vehicle, it becomes an integral part of your car or truck. You will never forget to bring it with you. You will never forget to turn it on. It is always ready to protect you.
