Why Dashcam Resolution Matters

Dashcam Resolution

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.

Dashcam Resolution
This inexpensive camera has a field of vision specified as 120 degrees. You can see the first third of the car door on the left side of the screen and half of the sign on the right. Note the presence of the lens flare in the lower left corner of the image and the poor contrast of the text on the main shopping plaza on the right.

 

Dashcam Resolution
The DR900S-2Ch has a field of vision of 136 degrees. You can see most of the car door on the left and all of the sign on the right. Almost the entire dash of the car is in the image. Impressive! High-quality optics prevent light reflections within the camera and prevent lens flare. Advanced exposure compensation makes the sign information much clearer.

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.

Dashcam 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.

Dashcam Resolution
The writing on the back of the bus is illegible. You can only just make out the last two numbers of the bus number and the license plate is completely blurred.

 

Dashcam Resolution
Stepping up to the 1296p resolution of the Mio makes the bus number legible. You can almost make out the license plate number.

 

Dashcam Resolution
The 2160p resolution of the BlackVue DR900S-2CH makes reading the writing on the back of the bus very easy. Not only can you read the bus number and license plate, but the writing on the door is also legible.

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.

Will Start-Stop Technology Affect Aftermarket Electronic Upgrades?

Stop-Start Technology

Many new cars and trucks come with a feature called stop-start technology. This system senses when the car is stopped at a red light or stop sign and shuts down the engine to save fuel. As soon as you release the brake pedal, the engine starts up again, and you’re on your way. The question for those of us who are interested in upgrading our vehicles is, does this technology work with our new electronics? Read on to find out if your new high-power amplifier, dash camera or radar detector will get upset when your car stops and starts.

How Does Stop-Start Technology Work?

Almost all new cars are controlled by computers. As such, the act of turning off your engine at a stop light is as simple as cutting spark to the ignition system and fuel injectors. To restart the car again, the vehicle initiates the start-up sequence as though you pressed the start button on the dash. The radio keeps playing, the climate control system keeps running and all the lights stay on while the engine is off. Other than an eerie silence and a split-second hesitation when it’s time to drive off, you don’t really notice anything.

Stop-Start Technology

In the background, the computer in your car is monitoring several systems to determine when it should stop the engine and when it needs to start it again. If it’s summer and you’re running the air conditioning, the computer will monitor the temperature in the vehicle. If it starts to warm up, it starts the engine so the compressor can run. If it’s winter and you have the heated seats and rear window defroster running, the system pays close attention to the current draw on the battery and its voltage. Brake pedal pressure, the position of the clutch (if you have one), engine coolant temperature, a buckled seat belt and many other conditions determine whether the engine will stop at a light and when it will restart.

What’s the Problem with Stop-Start Systems?

While saving fuel seems like a great idea, there is a drawback to this system in terms of aftermarket electronics in your car. When the engine starts, there is a large draw from the vehicle battery. In some cases, the battery voltage can drop well below 9 volts. For many years, electronic devices designed for use in cars had a low-voltage cutoff around 10.8 volts. In cases where the voltage drops into the 9V or less region, your amplifier, signal processors, source unit, dash camera or radar detector may shut down, then restart once the voltage increases. If the voltage drop is extreme, problems with the microcontrollers in your devices may occur.

Dealing with Stop-Start Vehicles

If you own a vehicle equipped with one of these fuel-saving technologies and are interested in adding aftermarket electronics, search for a specialist mobile enhancement retailer who is familiar with how they operate.

For low-power devices like signal processors, radar detectors, laser jammer and dashcams, voltage stabilization modules are available to help keep everything happy. Companies like ARC Audio design their new amplifiers and processors to handle these low-voltage conditions. Audison offers a product called the ES3 that will help maintain voltage to certain low-power devices. Work with your salesperson to choose products that list stop-start compatibility in their feature list.

Stop-Start Technology
The ARC Audio PS8-50 amplifier is designed to remain fully functional down to an impressive 6 volts, and the CPU can handle voltages as low as 4.5 volts.

You will also want to make sure that the battery or batteries in your vehicle are in good condition. Even after a few years of regular use or in even harsher conditions involving multiple short trips, batteries can build up a layer of sulfate on their lead plates that can dramatically reduce their current delivery efficiency. A high-quality battery charger with maintenance capabilities can be a great investment in maintaining the life of your batteries and, of course, will ensure that your vehicle is ready to go whenever you are. Some companies offer maintenance chargers specifically for start-stop batteries.

The CTEK MXS 5.0 includes charging cycles for conventional flooded lead-acid and AGM batteries. The Recondition mode can restore performance to an older, neglected battery.

Choose Your Technology Upgrades Wisely

If you’re thinking about upgrading the technology in your new car or truck that has stop-start technology, visit your local specialist mobile enhancement retailer and ask them about the solutions they have available.

How Does DragonEye ECCM Lidar Work?

DragonEye ECCM

Over the past few months, we’ve talked about how radar detectors and laser defense systems work. Now it’s time to talk about the dreaded and often controversial DragonEye ECCM-equipped lidar guns and why they’re so difficult to jam.

What Is DragonEye ECCM?

DragonEye ECCMLet’s break this down a bit. Based in Norcross, Georgia, DragonEye Technology is a company that develops electro-optical systems for the law enforcement industry. What does this mean? They make police lidar guns. They have two basic product categories: lidar speed measurement guns with and without a built-in camera.

Aside from the quality, accuracy and reliability of their products, DragonEye’s claim to fame is their anti-jamming technology called the Electronic Counter-Counter Measure (ECCM) system. ECCM was designed to prevent a conventional laser defense system from being able to disable DragonEye’s measurement system.

What Is ECCM?

In a conventional lidar gun, the emitting laser produces pulses of light and measures the time it takes for those pulses to be reflected back to the gun. Knowing the speed of light, the gun can calculate the speed of an object by analyzing the changes in reflection time for each pulse. For our discussion, let’s say that the gun sends out 150 pulses per second and expects to see that same frequency of pulses returned.

DragonEye ECCM
Conventional lidar guns emit a series of evenly spaced light pulses.

Laser defense systems on our cars and trucks are designed to detect these pulses of light and transmit additional pulses and varying timing patterns to prevent a lidar gun from being able to make a calculation.

When ECCM is in use, the spacing between the light pulses is somewhat random. We specify that is it only “somewhat” random because the gun needs to know when it emitted a pulse and be able to measure its reflection time. As such, there is a pattern, even though it’s complicated.

Again, purely as an example, a DragonEye Gun may start transmitting at 150 Hz (pulses per second), then ramp up to 1,500 Hz and back down.

DragonEye ECCM
DragonEye lidar guns with ECCM enable emit a pseudo-random pattern of light pulses. If your laser defense system can’t generate a similar but scrambled pattern, the gun will still take a reading and if you are speeding, you’ll likely get a ticket.

Defending Against Variable Pulse Rate Lidar

A simpler name for lidar guns like the DragonEye Compact and DragonEye Speed LIDAR with ECCM enabled is Variable Pulse Rate (VPR) radar. Other guns like the Stalker X-Series, the Laser Ally lidar and the LTI TruSpeed also offer VPR anti-jamming modes.

DragonEye ECCM
A representation of a laser defense system that has detected the variable pulse rate signal from a lidar gun with VPR technology.

It’s worth clarifying: It’s the frequency of the pulses that is changed, not the frequency or wavelength of the beam being transmitted. For most lidar guns, that beam remains in the 905 nanometer/331.26 terahertz range.

In order for your laser defense system to prevent a reading, the system needs to detect the algorithm used to modulate the laser pulse frequency and transmit a compatible yet scrambled pattern. The transmitted pulses can’t simply be random.

DragonEye ECCM
Different laser defense systems use different proprietary algorithms to confuse laser guns. In short, the transmitted signal prevents the gun from taking reliable measurements because there is no pattern to the received information.

The Cat-and-Mouse Game

DragonEye ECCMManufacturers of laser defense systems such as Escort, AL Priority, Stinger and K40 are constantly working on updating their firmware to maintain compatibility with new firmware from the lidar gun manufacturers. Statements about which defense systems defend against which guns should be qualified with confirmation of the firmware on the gun. A four-year-old DragonEye gun that has never had an update is going to be easier to jam than one that just came off the assembly line or has just returned from recertification and updates.

If you are shopping for a laser defense system, visit your local specialist mobile enhancement retailer and talk with them about where and how you drive. If they are truly experienced in the laser defense market, they will be able to tell you what radar and lidar guns are in use in your area and help you select a solution that will meet your needs. As always, we want to remind our readers that the performance of a laser defense system depends significantly on the installation. A reliable and accurate installation isn’t cheap but it can be the difference between getting a speeding ticket and arriving at your destination without delays.
