One of the key specifications you should look at when buying a dashcam is its resolution specification. Resolution refers to the number of pixels that the video camera records. This specification directly translates to how much usable detail the system offers. If you witness dangerous driving or an accident, being able to provide accurate information about the parties involved is crucial. In this article, we’ll compare images from dashcams from AccFly and Mio and the flagship product from BlackVue.

What Is Field of Vision?

In talking to consumers, it appears that some people get confused by the difference between the camera’s field of vision and its image resolution. Field of vision describes what the camera sees and is specified as an angle from the center of the lens. With a higher field of vision specification (also called viewing angle), the camera can see farther to the sides of the vehicle. Here are a few examples.

 

What Is Dashcam Resolution?

Resolution refers to the number of pixels contained in an image. More pixels mean that more detail and information can be captured. You can never have too much resolution.

In our comparison, we’ll look at our three cameras and compare cropped images of the back of the school bus to the left of the master image.

 

 

Dashcams Are a Great Safety Investment

The motivation for this article came from a friend who was in a sideswipe accident. The car that hit him kept on driving. Although his dashcam recorded that it was a blue Honda sedan, he couldn’t read the license plate, and the police were never able to find the owner.

If you are shopping for a dashcam, choose one with great optics and a high-resolution image sensor. You only get one chance to record details like a license plate. Drop by your local specialist mobile enhancement retailer to find out what is available for your vehicle.

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.

Technology Reduces Distractions

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.

There are several ways to add Bluetooth to your vehicle if it didn’t come from the factory with hands-free communication features. A Bluetooth kit from companies like Parrot, Cruz, iSimple and Axxess can operate as a standalone solution or one that integrates with the speakers or radio already in your vehicle.

The second option is to upgrade your factory radio with an aftermarket unit that has Bluetooth hands-free calling and audio streaming capabilities built in. The majority of these solutions also add Siri Eyes Free and may even allow you to pair two phones at once.

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.

CarPlay and Android Auto also help reduce distraction by making it much easier for your son or daughter to choose the music they want. They can pick a song, artist, album or even genre of music from the media stored on their smartphones. They also have access to streaming music services like Pandora, iHeartRadio, Slacker and Tidal – all by just talking to the radio in the vehicle.

Backup Camera and Parking Sensor Systems

We all know that backing into a parking spot is the ideal parking solution, since it makes pulling away much safer. Backing up can be tricky, especially when it’s hard to see objects or people behind the vehicle. An aftermarket backup camera system or parking sensor system is like having our own personal ground crew, guiding you to safety.

Parking sensor systems use an array of ultrasonic transceivers to detect objects behind your vehicle. From an abject as narrow as a signpost to a tricycle or trash can, objects of almost any size are detected very reliably. Most systems produce a warning beep when the objects are first detected at a distance of about 3–4 feet. The beeps increase in speed as you get closer and closer to the object. Finally, at about 12 inches, the beeps turn into a solid tone to let you know it’s time to stop. Parking sensor systems are also available with sensors for the front of the vehicle. These are a great option for parking in a garage or underground structure.

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.

Blind-spot Monitoring Systems

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 most-popular blind-spot warning system uses a pair of radar or ultrasonic transceivers that your installer mounts behind the rear bumper cover. These units monitor the area in the lanes beside yours for the presence of other vehicles or pedestrians. When someone or something is in your blind spot, a warning light will illuminate inside the vehicle to let you know what side the obstruction is on. In most installations, the warning lights are installed at the base of the A-pillar. In some systems, an audible warning will be produced when someone is in your blind spot and you turn on the correlating turn signal.

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.

Collision Avoidance Systems

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.

Video Recording Systems

Another great option for a younger driver is to install a dash cam. A dash cam is a small video recording system that mounts to the windshield of the vehicle. The camera not only records everything in front of the vehicle, but most include an onboard GPS receiver and an accelerometer to store vehicle speed and driving behavior. If your son or daughter knows that you are recording everything they do, they are less likely to drive dangerously.

GPS Locating Systems

The last option to consider is a GPS locating system. These devices combine a dedicated cellular data module with a compact GPS receiver to allow you to look at the vehicle location and speed any time you want. More-advanced systems include the ability to configure over-speed warnings, aggressive driving warnings and geofencing options that will alert you if the vehicle enters or exits a preset area. Just as with the dashcams, if the driver knows you are monitoring their location and speed, their behavior will change for the better.

Protect Teenage Drivers in Your Home

While no technology can replace experience and intuition, driving assistance devices are a great way to give teenage drivers a better chance of avoiding an accident. If you are interested in any of the products mentioned in this article, visit your local specialist mobile enhancement retailer and ask about compatibility with your vehicle.
