Automotive Dashcam Features Explained

Dashcam Features

A dashcam is a compact camera system designed with automotive-specific features to capture video of everything that happens in front of your car or truck. The video files from a dashcam can protect you from fraud or false accusations in the event of an accident. Let’s take a look at some of the most popular options available to enhance the information captured by these amazing safety systems.

Dual Camera Systems

Dashcam FeaturesMany dashcam solutions are available with a secondary camera that can be positioned to monitor the interior of the vehicle or the traffic behind your car or truck. These systems record from both cameras simultaneously to give you a complete record of everything happening. Uber, Lyft and taxi drivers are particularly fond of these dual camera systems to record the behavior of their customers.

Built-In LCD Screen

Dashcam FeaturesTwo types of dashcams are commonly available: Those with and without an LCD screen. In most products, the addition of a feature like a screen is perceived as an upgrade, but with dashcams, this isn’t always the case.

Dashcam systems without displays are often physically smaller, allowing your installer to mount the camera under your rearview mirror for a nearly invisible installation. These dashcams typically include a series of LEDs to indicate when they are powered up and are recording. The drawback to these designs is that you need a smartphone or computer to view videos stored by the system. You will also need to make system configuration adjustments using a phone or computer, so the installation time is longer.

Cameras with integrated displays are often physically larger than those without a screen. Depending on the design of the camera, color displays measure from 1.5 to 3.5 inches diagonally. In addition to letting you look at videos directly on the system, cameras with displays typically have easy-to-understand setup menus right on the unit. Many higher-end cameras include a touchscreen to make adjusting the system even easier.

Integrated GPS Antenna

Another popular dashcam feature is a built-in GPS antenna. The software in the camera will use the information transmitted by the GPS receiver to store vehicle speed and location along with the video information. Most quality dashcam manufacturers offer PC and Apple playback software that will show your location and speed along with the video recording.

Dashcam Features

Integrated Accelerometer

Another great feature to look for is a camera with an integrated accelerometer. These cameras store information about G-forces in all three axes along with the video. Your installer can typically configure the camera to automatically store video files if the camera detects a sudden jolt that might have been caused by an accident.

Parking Mode

Dashcam FeaturesMany solutions offer what is called parking mode. In most cases, when your installer has wired the camera to a constant power source (one that is active even when the ignition is turned off), the camera will stop saving video to the memory card. If the camera detects changes in the video image (from someone or something entering the field of vision) or motion from the built-in accelerometer, the system will wake up and automatically store a video file. In most cases, the recording starts 5 to 10 seconds before the trigger so you can see what led up to the event.

An important note about parking mode: Please make 100% sure that your camera has a low-voltage shutdown feature to prevent the battery in your car or truck from being killed and leaving you stranded. If your camera doesn’t have this feature, several manufacturers make external battery packs and control modules that will reduce or eliminate the load on your vehicle battery. If you don’t drive your car or truck every day, an external battery pack or at least a power management controller is a very wise investment.

High-Resolution Cameras and HDR Mode

Most quality dash cameras have high-definition image sensors capable of storing 1920-by-1080-pixel video files. Compared with VGA or 720p recording, these high-res files allow you to see license plate information, phone numbers or other identifying marks on moving vehicles. Some of the newest cameras record at 4K (4096 by 2160) resolution for an increase in detail of 4.3 times over HD resolution. Yes, this higher resolution with fill up a memory card much more quickly, but the added detail is quite worthwhile. We suggest buying a camera with as much image resolution as possible for your budget.

High Dynamic Range

Another popular feature is called high dynamic range. This is a video contrast compression technology that helps to make dark areas of the image brighter and bright areas darker to make everything in the video easier to see and understand during playback. Turning on HDR processing can help reveal more detail at night or in bright sunlight situations.

Wi-Fi-Enabled Dashcam Feature

Dashcam FeaturesThe last feature we will talk about is Wi-Fi. Many premium cameras include an integrated Wi-Fi hotspot that allows you to connect your phone to see videos or make adjustments to the system. This is a particularly convenient feature on cameras that don’t have a touchscreen as it makes adjusting menu options quick and easy. Apps for iOS and Android-based smartphones are typically available for dashcams with Wi-Fi built in.

Some advanced dashcams include the option to automatically connect to an internet hotspot to upload video files to the cloud to make information access easy and efficient.

Protect Yourself with a Car Dashcam

If you are concerned about fraud from other drivers or pedestrians, or you want undeniable proof of who’s at fault in the event of an accident, then you owe it to yourself to invest in a quality dashcam. Drop by your local specialist mobile enhancement retailer today to find out more about the systems that are available and arrange for expert installation in your vehicle.

Product Spotlight: Alpine i407-WRA-JL

Alpine i407-WRA-JL

If you’ve been paying attention over the last few years, you’ll know that the folks at Alpine have been offering many different audio system upgrade solutions for Jeep Wrangler and Gladiator vehicles. These offerings range from head unit replacement solutions to complete audio systems with amplifiers and subwoofers. In this Product Spotlight, we will look at the i407-WRA-JL radio upgrade kit. Let’s check it out!

What is the Alpine i407-WRA-JL Kit?

The i407-WRA-JL is a radio upgrade kit for 2018 and newer JL chassis Jeep Wranglers and 2020 and newer JT chassis Jeep Gladiators. The kit includes an Alpine iLX-407 source unit along with mounting brackets, a radio trim kit, a new auxiliary input jack, all the wiring harnesses, a camera interface module, and an iDatalink Maestro RR integration module. The concept was to provide retailers with a package with everything needed to upgrade the entertainment system and prevent surprises in the installation bay.

The mounting brackets and radio trim are designed to make the iLX-407 radio look right at home in your Jeep.

In terms of integration, the factory-installed backup camera on these Wranglers and Gladiators uses a communication protocol called Low-Voltage Differential Signaling (LVDS). This signal isn’t directly compatible with aftermarket radios. As such, the i407-WRA-JL kit includes an interface module that converts the LVDS signal into a composite signal so the camera will work with the included iLX-407.

The kit also includes an iDatalink Maestro RR interface. This data interface and harness allows the new radio to plug into the wiring connectors from the original radio and provides access to the Jeep’s data network. Information like vehicle speed, engine RPM and much more can be displayed on the radio. The climate control settings are also adjustable from the face of the new radio.

One item worth noting is that if your Jeep is equipped with the factory amplifier, an optional interface module called the KCX-F200INT is available to let the new radio connect properly.

Alpine iLX-407 Features

The double-DIN iLX-407 is the radio at the heart of the i407-WRA-JL kit. This radio features a 7-inch anti-glare touch screen with a resolution of 800×480 pixels. The hard controls are along the bottom edge of the front panel. Apple CarPlay and Android Auto are included, as is Bluetooth for hands-free streaming or phone calls. The tuner in the unit offers support for HD Radio, which dramatically improves the quality of FM radio. There’s an HDMI input on the rear of the chassis, so you can theoretically connect a gaming system or a laptop, if you want. There are two camera inputs and support for the SiriusXM SXV300 tuner module.

The I407-WRA-JL kit includes an interface that allows the LVDS factory-installed camera to work with the new radio.

If you want the best sound quality from your music, playing digital audio files from a USB drive is the way to go. The iLX-407 supports MP3, WMA, AAC, FLAC, and WAV audio formats with a maximum sampling rate of 48 kHz. The unit will also play AVI, MP4, MPG, MOV and WMV video files with H.264 or MPEG-4 video encoding. The maximum video file size is 4 gigabytes.

Audio Processing Features

The deck includes a four-channel amplifier rated at 16 watts per channel and in compliance with the ANSI/CTA-2006 standards for car audio amplifier power specifications. The triple preamp outputs are rated for up to four volts.

The iLX-407 is impressive in its audio processing features. It has a simple five-band graphic equalizer to let you fine-tune the system to your listening preferences. The more advanced crossovers offer adjustable slopes from six to 24 dB/Octave and filter frequencies from 20 to 200 Hz with high-pass filtering on the front and rear channels and a low-pass filter for the subwoofer output. There’s also a level control for each output, which many source units overlook. Oh, and the subwoofer level control can be adjusted from 0 to 15 with a polarity inversion option to potentially help the subwoofer’s output blend with the woofers in the dash and overhead sound bar.

The Time Correction setting screen allows your installer to dial in delays to each of the six outputs (which include the four built-in amplifier outputs) in 1 millisecond steps or set distances to the speakers in 3.4 centimeter steps. There are three presets available to store different Time Correction configurations. This is ideal if you want one alone in the vehicle or have a passenger, which requires different settings.

Understanding Specifications: Operating Voltage Tolerances and Protection Circuits

Operating Voltage

To close out our series of educational articles on amplifier specifications, we are going to talk about operating voltage limits and, by association, the protection circuits built into a car audio amplifier. In the good old days of electrical systems that were composed of an alternator, battery, switches and a couple of relays, delivering a relatively constant voltage to a car audio amplifier was easy. New technologies and limits on battery, alternator and wire size have made it much more difficult to keep our amplifiers happy.

Automotive Start-Stop Systems Cause Low Operating Voltage

Operating VoltageWith the never-ending battle to eke out every ounce of fuel efficiency from the vehicles we drive, automakers have resorted to systems that will shut down the engine to save fuel while idling. Transitioning from standard idle mode to the shut-down state doesn’t pose a problem for most amplifiers as the battery voltage only drops to the 12.2 to 11.5-volt range. If the voltage starts to drop because the car has been idling too long, the engine will restart automatically.

Operating VoltageWhat poses a problem for modern car audio amplifiers are the voltage dips associated with the engine starting. In conventional vehicles, the stereo is off while you are starting the vehicle. These start-stop systems keep everything running and playing as the engine restarts. Electrical system voltage can drop below seven volts while the engine cranks. Many amplifiers shut themselves down below nine or ten volts, and as such, your music would stop playing. While a pause in your music isn’t truly problematic, it can be annoying if you are stuck in stop-and-go traffic.

New amplifier designs include circuitry that will keep the amplifier active during brief low operating voltage conditions. Some companies specify their amps as being able to handle as little as 6 volts for as long as 5 seconds to ensure that your music plays without interruption. This same start-stop compliance design is required for digital signal processors to prevent them from shutting down during engine restarts.

Car Audio Amplifier Protection Circuitry

Operating VoltageThree decades ago, if you shorted the outputs of an amplifier, it would blow up, occasionally with spectacular results. Modern amplifiers include protection circuits that monitor different functions and automatically shut the amp down when an unwanted condition occurs. Most amplifiers include protection against overheating or short circuits on the speaker wires. Better amplifiers may provide a warning if a power connection over-voltage condition occurs that could damage the components inside the amp.

A select few manufacturers provide computerized monitoring of different parts of their amplifiers and flash error codes to let users know why the amp is in protection. Short circuits, over-voltage, under-voltage, over-temperature on the power supply and output stage and a notification about repeated short circuits are provided. This information makes it much easier and more efficient for a technician to troubleshoot an installation or speaker issue.

How Car Audio Amplifiers Handle Over-Temperature Conditions

Operating VoltageThere are two ways for an amplifier to protect itself if it gets too hot. The most common mode is for the amp to stop playing music so that the power supply and output switching devices can cool off. The second option is for the amp to reduce the output signal so that less heat is created. While it’s nice that your music won’t stop playing, most consumers tend to try and turn the volume up higher when the music gets quieter. Eventually, amplifiers that roll back power will go into a state of full protection and shut themselves down to protect components.

If you live in an area that gets hot during the summer, choosing an amplifier with adequate cooling from a large heatsink or a fan is a good idea. Cramming a tiny little amp into the corner of your trunk or cargo area may not be the best choice in this situation.

Product Spotlight: KICKER LX1200.5

ICKER LX1200.5

If you’ve been paying attention, then you’ll know that DSP-equipped car audio amplifiers are pretty common these days. KICKER introduced a new series of amplifiers called LX. These beasts are not only packed with serious power production capabilities, but they include digital signal processing and a unique configuration solution that separates them from everything else on the market. We’ll focus on the five-channel LX1200.5 in this Product Spotlight.

What is the KICKER LX1200.5 Amplifier?

The KICKER LX1200.5 is a five-channel amp with an integrated digital signal processor. The amp is based on a cast aluminum chassis that measures 12.625 inches in length, 8.875 inches in width and stands 2.375 inches tall. All the connections are hidden under a removable panel along the long edge of the amp. The panel is held in place with magnets for a clean and tidy appearance. Wire connections are made via terminal blocks with heavy-duty set screws. Interestingly, there are only three controls on the amp, which are gains for the subwoofer, AMP1 and AMP2 channels.

Power-wise, KICKER rates the output of AMP1 and AMP2 at 125 watts per channel into four-ohm loads and 175 watts per channel when driving two-ohm loads. The channel pairs can be bridged to provide 350 watts into a single four-ohm load. The subwoofer channel produces 300 watts into a four-ohm load, 550 watts into two ohms and an impressive 700 watts when driving a one-ohm load. All specifications include the 14.4-volt, less than 1% THD+N qualifications, so you know they are comparable to other quality brands. The amplifier’s signal-to-noise ratio is greater than 75 dB, referencing one watt of output into a four-ohm load.

ICKER LX1200.5
To keep the installation tidy, signal, speaker and power connections are all made along one side of the amp.

OEM Audio Integration

The KICKER team knows that many amplifier installations in modern vehicles use factory-installed source units. This means the amplifiers need to accept speaker-level signals. The LX1200.5, like other models in the LX Series includes fully differential speaker inputs that can take up to 40 volts of signal without needing an external interface. In low-level mode, the preamp inputs accept up to 5 volts.

The amplifier also has two turn-on modes. The amp can be activated with the typical 12-volt signal from an aftermarket source unit or switched to DC offset detection to monitor the speaker wires for a voltage from a factory radio. KICKER calls this their FIT+ technology.

Speaking of integration, the LX amplifiers have input gain matching LEDs that illuminate when you have reached the maximum output capabilities of the amplifier.

Integrated Digital Signal Processing

Unlike most DSP-equipped amplifiers on the market that require a laptop or tablet to set up, KICKER includes a controller with the amp called the LX Control Center. This compact controller features a two-line LCD screen, four rotary encoders and buttons to access different amp channels and functions.

ICKER LX1200.5
Each amplifier includes an LX Control Center (LXCC) to let your installer configure the amp quickly and easily.

In terms of signal processing, your installer can apply high-pass, low-pass or band-pass crossover to each of the three channels on the amp. The high-pass filters are adjustable from 20 Hz to 5 kHz and the low-pass from 40 Hz to 5 kHz. Slopes can be set to 12 or 24 dB Linkwitz-Riley alignments or 12, 18 or 24 dB/octave Butterworth. You’ll want to use the Linkwitz alignment so you can set the crossover points at the same frequencies. The subwoofer channel low-pass filter is adjustable from 20 to 160 hertz and there is an infrasonic filter that can be set from 10 to 80 Hz to control subwoofer cone excursion.

KICKER includes a signal delay for the left channels on both AMP1 and AMP2. Your installer can delay the output of the left channels, which correlate to the speakers closest to the listening position in 0.1 millisecond steps, up to a maximum of 10 milliseconds. When set properly, adding delays to the closer speakers can help improve imaging and staging.

The subwoofer channel has a parametric equalizer that can be set between 20 and 80 hertz with a Q factor between 1 and 5 and a maximum gain of 6 dB. If you want to add a little Kick, no pun intended, this is the perfect solution. The LX amps also include SHOCwave 2.0. This feature analyzes audio information and creates a harmonic one octave below the fundamental to restore audio information lost by many factory-installed amplifiers. If you want to rumble, SHOCwave 2.0 can do it!

Once your installer is done setting up the amp, the LXCC (LX Control Center) can be disconnected from the RJ45 port, and the included LX Remote Control (LXRC) can be plugged in. This multifunction remote controls the subwoofer level and SHOCwave 2.0 functionality and even shows battery voltage using the LEDs around the perimeter.

ICKER LX1200.5
The included LX Remote Control (LXRC) is much more than just subwoofer level control.

Full Amplifier Family

The new LX series from KICKER includes the LX1200.5 five-channel we’ve discussed, a seven-channel LX1300.7 and the monster LX3000.1 3000-watt monoblock in the same chassis size. The LX series includes a four-channel LX500.4 and LX850.1, LX1250.1 and LX1300.7 in a smaller 9.625-inch long chassis. The width and height of all the amps are the same, so mixing and matching models is easy.

Speaking of design flexibility, the little illuminated badge in the center of the amp can be rotated 180 degrees to align with however your installer configures the amps in your vehicle.

Car Audio Amplifier Remote Control Options

Amp Remote

If you are thinking about having your local mobile enhancement retailer add a subwoofer amplifier to your car or truck, you may want to ask them about the remote level or bass boost control options that are available. Being able to adjust the amount of bass your system produces from the driver’s seat allows you to fine-tune the system for the music you are listening to or your mood. Let’s look at five of the most popular options available to adjust the output of a new subwoofer system.

Dedicated Remote Level Control

Amp RemoteMany subwoofer amplifiers have a built-in jack that your installer can connect to an included (or optional) remote level control. In most cases, these are RJ11 jacks, similar to what home phones use. The remote includes a long cable that can be run to a location on the dash or center console where the knob or control panel can be installed.

How the remote works is important to the overall reliability of your sound system. To prevent distortion from clipping, the remote should ideally only serve as an attenuator. Your installer will configure the system to produce maximum power from the amp with the level control turned up all the way, then you can turn it down to suit your listening preferences.

Digital Signal Processor Remote Controls

Amp RemoteAlmost all DSP manufacturers offer some sort of remote control that is compatible with their processors. These remotes can serve as master volume controls or subwoofer level controls and can usually select different presets if the processor supports that function. Whether the processor is a stand-alone system or integrated into an amp, adding a remote is a great choice.

Some processors have provisions to add a remote control that can be assigned to specific channels and operate over a specific range. This remote can be configured to act as a level control for a subwoofer, a center-channel speaker or rear speakers, depending on how the system is configured. This style of remote can also serve as a master volume control for the amplifier in instances where you are not using a radio with a volume knob as a source. This single knob is often easier to use and much less expensive than a full controller.

Remote Bass Boost Controls

Amp RemoteSome inexpensive amplifiers come with a remote bass boost control. These controls work in the same way as the adjustment potentiometer on the side of an amp to apply a narrow EQ band of signal boost to the audio signal.

There are two problems with bass boost controls. First, they increase the output of the amp, so your system needs to be tuned with the control at its maximum setting. This configuration makes it difficult to blend the sound of the subwoofer with the mid-bass speakers. Secondly, using large amounts of boost often sounds unnatural. Boosting the region around 45 or 50 Hz is a lot of fun, but the audio information down at 25 and 30 Hz and up at 70 to 80 Hz is just as important. Ideally, a remote level control is a much better choice than a bass boost control.

Source Unit Subwoofer Level Controls

Amp RemoteIf you have upgraded your sound system with a new radio or multimedia receiver, most include a subwoofer output level adjustment in the audio configuration menu. It’s worth noting that these radios typically don’t produce their maximum output signal on the subwoofer preamp connections unless the subwoofer level control is at its highest setting.

Many years ago, a radio manufacturer placed a rocker switch on the front panel of one of their radios that provided direct access to the subwoofer output level. This was a truly genius idea! These days, you have to press a few buttons or navigate a menu option or two to access the adjustment menu.

Integration Processor Level Controls

Many audio integration processors and converters (often called Line Output Converters or Line Level Converters) have an option for an external remote level control. Depending on the design of these processors, the output controlled by the knob could be paralleled off of a single stereo input, or be from a second dedicated input. If your audio system needs a processor to take the signal from the factory radio or amplifier and turn it into something the amp can use, look for something with a remote level control.

Upgrade Your Car Audio System Today!

Upgrading an existing subwoofer or adding one to your factory car stereo is the most dramatic improvement you can make to your mobile audio system. Alleviating the need for the small speakers in your doors, dash or rear parcel shelf to try to produce bass makes them sound better, play louder and last longer. Drop by your local specialist mobile enhancement retailer today to find out how you can add a subwoofer enclosure and amplifier with remote level control to your car stereo system.
