Have you ever been driving along and witnessed something that you wish you could have captured on video? It could be a car accident, strange or reckless driving behavior or just something interesting you want to share on social media. We most certainly can’t drive around with our smartphones in our hand, and when something worth recording does happen, we’ve usually missed the opportunity to capture the moment. A dashcam system is the solution. Read on to learn everything you ever wanted to know about dash cameras and how they work.
What is a Dashcam?
A dashcam is a compact audio and video recording system that is designed to mount to your windshield. The camera faces forward and includes a wide-angle lens that will capture almost everything that happens in front of the vehicle. Most cameras on the market include a built-in microphone, so you get the entire play-by-play of the event as it occurs.
Basic Dash Camera Features
Dash camera systems are typically wired into the ignition circuit of your vehicle and begin recording as soon as you start your car or truck. There is no need to remember to press a button. Most camera systems include an integrated accelerometer that records forces in all three axes along with the video. This information can be used to show acceleration and braking and cornering forces, as well as to detect impacts in the event of an accident.
The better camera systems on the market use an SD or micro SD card to store video information. These digital storage formats are compact and reasonably reliable. The small cards can be removed and connected to a computer in your home or office to view videos.
How Dash Camera Video Recording Works
As mentioned, most cameras start recording as soon as the vehicle ignition is turned on. Options in the setup menu allow the installer to configure the length, frame rate and the resolution of the video. Typical video lengths are one, three and five minutes. These short lengths make it easy to pick out certain events while ignoring long periods of uneventful driving.
Normal videos are stored on the memory card in a specific folder called Videos or something similar. Once the folder fills up, the oldest video is deleted to make room for a new one. The number of videos stored on the card depends on the resolution and, subsequently, the size of the video files in relation to the total storage space available on the storage device.
Most systems have a secondary folder with a name like Event. The videos stored in this folder have been flagged for safekeeping. A threshold for the onboard accelerometer can be set to trigger an event recording. Sudden deceleration caused by slamming on the brakes or hitting an object are typical trigger events. Most systems also include a manual trigger button that will let you save a file to the Event folder.
Going Back in Time
We mentioned at the begging of this article that a dashcam is a great tool to record an event that has already taken place. While that sounds a bit like time-travel, it’s quite simple in operation. Allow us to explain.
Your dash camera is always recording and saving content to the memory card. In the event of an automatic or manual trigger, the dashcam saves five to 10 seconds’ worth of information from before the trigger and 30 to 60 seconds of video after to the file in the Event folder. You can witness a car accident, come to a full and safe stop, then press the trigger button to store the entire experience for later review.
Should My Dash Camera have a Screen?
There are two basic styles of dash cameras: with and without a display screen. The inclusion of a screen makes it much easier to install and aim the camera properly. Having a screen also allows you to play videos back right on the camera unit. The tradeoff is, of course, the size of the camera system. Including a screen will make the camera larger. Choosing a camera with or without a built-in screen depends on your application and personal preference.
Dash Camera Options and Accessories
Many dash camera systems include or have a provision for an optional GPS receiver. When equipped with GPS, the longitude, latitude and speed of the vehicle are stored along with the video files and accelerometer information. Many video playback software packages (available as a download from the camera manufacturer’s website) overlay the vehicle location on Google Maps during playback.
Another very popular option for dash camera systems is a second camera. This camera can be placed in the rear window to capture activity behind the vehicle, or placed inside the vehicle near the rearview mirror to record the interior of the vehicle. Taxi, Uber and Lyft drivers like the ability to record what’s going on inside the vehicle.
Another feature available in premium cameras is the inclusion of a Wi-Fi network hotspot. This network connection allows you to communicate with the camera system using your smartphone. Some interfaces allow you to download videos from the camera to your phone for sharing. Others include the ability to configure settings on the camera remotely. A few companies even include cloud-based image storage. When you arrive home, you can connect your dashcam to your home Wi-Fi to upload videos.
Parking Mode Recording
Another popular camera option is called Parking Mode. When activated, the camera will operate even after the ignition is turned off. Parking Mode works in different ways for different cameras. Some record at a much lower framerate. Some monitor the image for changes (when a person approaches the vehicle, for example) and only start recording when a change is detected. Parking Mode is a great feature for people worried about someone breaking into or vandalizing their vehicle.
Battery management is an important consideration for dash camera systems that will continue to function after the ignition is turned off. The last thing you want is to have your camera run all night and drain your battery, making it impossible to start your vehicle the next morning. Some cameras have a built-in shutdown circuit that turns the camera off when the battery reaches a selectable voltage. A better solution is to add a dedicated battery for the camera system. A secondary unit reduces wear and tear on the main battery while providing excellent protection.
Let’s Talk About Image Quality
Beyond features, buying a dashcam is similar to buying any other video or still picture camera. The amount of information stored depends on the resolution of the camera system, the quality of the image sensor and the optics (lens quality) of the system. If you want a yes or no answer to who caused an accident, any recording system will work. If you are hoping to read a license plate or phone number from the side of a vehicle, you can never have too much resolution. It’s up to you to decide how much is right for your application.
In addition to resolution, consider image quality. Dash camera systems are hampered because the brightness and contrast required is always changing. The camera needs to function reliably when you are driving toward the sun or at night with only headlights lighting your way. The speed and accuracy with which the camera can adjust to these changes is an important factor in ensuring optimal image quality.
Finally, construction materials and quality are also a consideration. Does the lens assembly use inexpensive plastics that may distort when they get hot or turn yellow after prolonged exposure to the sun, or are the lenses made of glass? It can be very difficult to determine the quality of the internal components of a camera, so be sure to do your research.
Why You Need a Dash Camera
Finally, we should discuss just why it is a great idea to have a dash camera installed in your vehicle. There’s no doubt that a good public shaming on Facebook for someone who cut you off is great entertainment, but the need to protect yourself against fraud and false accusations is very real. You may have seen a news report of video of someone jumping on the hood of a vehicle stopped at red light and claiming the driver hit them. Believe it or not, this does happen. Another popular scam is for a driver to back their vehicle into a stopped car or truck while at a red light. The driver of the offending vehicle will claim that you drove into them. One of the latest scams involves drivers being flagged down by a person on the side of the road. The person will claim they are out of gas and offer supposedly expensive jewelry as collateral in exchange for some money to get gas. If you decide to stop, be sure to let the person know you have a dashcam recording everything, including their license plate.
Protect Yourself with a Dash Cam
Before you buy an inexpensive dashcam system online, drop by your local mobile enhancement retailer and ask about the features of the products they offer. More often than not, you will find much better performance and reliability from a premium product. You only get one chance to record an important event, so make sure you capture all the information you want or need.

Did you know that teenage drivers are three times more likely to be involved in a motor vehicle accident than those who are 20 or older? With their relative lack of experience and the constant bombardment of distractions, it’s no wonder that young people are at risk. The aftermarket mobile electronics industry offers a wide variety of systems and solutions that can protect teenage drivers.
While it’s certainly best practice to focus exclusively on the task of driving when behind the wheel, now and then, we need to take an important phone call. Bluetooth hands-free communication became a life-saver in the late 2000s, allowing a driver to talk with someone without having to hold the phone.
For the ultimate in smartphone integration, an aftermarket multimedia receiver with Apple CarPlay or Android Auto adds a wide variety of communication, information and entertainment options that can be accessed using voice commands. By simply pressing and holding a button on your steering wheel, you can ask these systems to place a phone call, send a text message, or search for an address and provide navigation instructions. The voice recognition technology built into a smartphone allows the driver to keep their eyes on the road and mirrors to ensure he or she is safe.
A backup camera system uses a compact camera to let you see an image of anything behind the vehicle. The image from the camera can be displayed on many factory-installed infotainment systems, a new rearview mirror with a built-in screen or an aftermarket multimedia receiver. The image appears automatically as soon as you put the transmission into reverse, so you don’t have to remember to press any buttons. Many video systems will support a secondary camera that faces forward on the vehicle. These second cameras are a great option for trucks, vans and SUVs whose large dimensions make them difficult to park.
One of the biggest challenges for a new driver is traveling on the freeway. Keeping track of the position of cars and trucks around one’s vehicle can be very difficult. An aftermarket blind-spot monitoring system lets you know when someone is driving beside you and can dramatically reduce the chance of changing lanes when someone is in your way.
The second option for blind-spot monitoring is a camera system. In these systems, cameras mounted underneath your rear vision mirrors display an image of the area beside your vehicle when you activate the turn signal. Just like the backup camera systems, there are many options available to display the image from the cameras.
If you are looking for the absolute state-of-the-art in protection, look into the Mobileye series of products. The Mobileye 660 uses a precisely calibrated camera to monitor the area in front of the vehicle and alert the driver when you are leaving your lane, approaching another vehicle too quickly, or at risk of colliding with a vehicle or pedestrian approaching from the side. This is the same technology that Tesla uses in its AutoPilot system.
Another great option for a younger driver is to install a dash cam. A

With the cold winter behind us and school finished for the year, it’s time to start thinking about getting our cars, trucks and SUVs ready for our summer road trip or vacation. Whether you have toddlers or teens, keeping everyone in the vehicle entertained during the drive will make the entire adventure much more enjoyable. Let’s take a look at some of the options available to keep your passengers happy as you rack up the miles this summer.
The classic road trip upgrade would be to have an 
There is no specific benefit or drawback to choosing an overhead monitor versus headrest monitors. Of course, with the overhead, everyone will have to watch the same programming. If the ages or interests of your passengers vary, though, this might not be the best choice. A large overhead monitor also can block the view from the rearview mirror when it’s folded down. Finally, in most applications, installing an overhead monitor requires permanent modification to the roof liner of the vehicle. If you leased your car or truck, you probably want to return the vehicle with the video system in place.
There are many ways to provide Internet access while on the road. We all seem to have cellphones with gigabytes of data access each month. Many smartphones will accept Wi-Fi connections from other devices, but if you happen to step away from the vehicle, the show stops. One solution is to have a mobile hotspot installed in your vehicle. Verizon, AT&T and Boost Mobile in the U.S. and Telus, Rogers and Bell in Canada offer portable solutions that work just like a wireless router in your home. Your kids can pair their tablets or computers to stream content to a video screen or play games with their friends over a high-speed 4G LTE connection.
If you are using your phone for navigation, your better half is posting on Facebook and the kids are building landscapes in Minecraft, you will need a way to keep all of those devices charged up while on the road. There are numerous options for adding USB charging ports anywhere in the vehicle. Having a few high-current USB ports for your rear seat passengers negates the need to keep battery packs charged up and can tidy up a lot of wiring clutter. Your installer can wire the USB power ports to the vehicle ignition switch so there is no chance of the devices draining your car battery when the vehicle engine isn’t running.
If you don’t have a navigation system built into your vehicle, you may want to consider one. Unlike the days of old, when maps from the auto club where the only way to help you get to your destination, modern navigation system provide detailed turn-by-turn directions. If you happen to veer off-course for a little sightseeing or make a wrong turn, the navigation system will update the route almost instantly to get you back on track.
If you are shopping for a new multimedia receiver, you will want to look at a solution that includes Android Auto and Apple CarPlay. These smartphone integration technologies work with the Google or Apple voice recognition system built into your smartphone to allow you to perform commands by talking to the radio. You can make phone calls, listen to incoming text messages, and dictate a response or check your voicemail. Both systems also include navigation systems that monitor traffic flow in real time to ensure you have the most-efficient route. Google and Apple are constantly updating their map data, so you’ll never need to buy a map update again.

Most mobile electronic retailers can help you out with automotive lighting upgrades to make driving at night safer. A quality LED or HID bulb upgrade in the factory lighting system can make a world of difference. If you are looking for fog or 
In a nutshell, a DSP uses a microcontroller that is designed specifically to manipulate audio signals in the digital domain. Pretty much all of the DSP devices on the market include crossovers, equalizers and signal delay features that we can use to optimize the performance of your sound system.
At the simplest level, a DSP can be considered a glorified yet extremely precise tone control. When you combine the features of a processor with measurements from a real-time analyzer, a properly trained technician can dramatically improve the tonal balance and accuracy of your audio system. Vocals and instruments will sound more as though you are in the presence of a live performance as opposed to listening to a recording. Expert technicians can use stereo equalization to improve the staging and imaging characteristics of your sound system, helping to increase the realism of the listening experience further.
Let’s continue with our three-way system example. In many systems, the tweeters are mounted at the top of the door, in the sail panel, in the dash or on the A-pillar. Midrange drivers in a system like that are typically 6.5 inches in diameter and are installed in the factory door location. Finally, woofers typically require an enclosure and are mounted in the trunk, cargo area or under the rear seat of a pickup truck. The distance between the listener and each speaker is different, as is the difference between the left and right speakers. These pathlength differences result in us hearing the closest speaker first, which makes our minds think that that is the source of the majority of what we are hearing.
Well, yes and no. Good quality processors start around $400 plus installation and require at least an hour to configure in most vehicles. If you have a complex multi-channel system, you may need a DSP with more input and output channels and additional time to configure the system in your vehicle.
