Dash Cameras – Buyer’s Guide
If you are seeking the best dash cam for your personal or business needs, you need to first flush out what those specific needs include. These are your considerations for buying your dash cam. Below are several features, options and functions you need to consider before shopping for a dash cam, so you can find the best possible fit.
Your Dash Camera’s Point of View
If you only want to record what you see in front of your vehicle, most dash cams will suit your needs. Most of today’s dash cameras actually mount on your windshield, focusing on the road ahead of your vehicle to a specific field of view. These are known as single-lens dash cams.
If you want to record video of behind your vehicle, as well as through the front windshield, you need a dual-lens dash cam. A dual-lens dash cam simply includes two camera lenses, also known as “channels.” These cameras record footage through both lenses at the same time.
Dual-lens dash cams are available for recording through the front windshield and rear of the car at the same time, as mentioned before. But they are also available for recording video through the windshield and inside your vehicle. This means you can see what is happening outside the car and inside among passengers, at the same time.
These types of dual-lens dash cams are perfect for drivers shuttling passengers as part of ride-share or taxi services. They also work well for fleet managers, delivery companies or parents wanting to monitor people inside the vehicle, as well as the road ahead. But anyone can benefit from a dual-lens dash cam, particularly when it comes to proving your actions as part of an accident case.
Some dual-lens dash cams have fixed lenses on one camera body. Other dual-channel dash cams feature secondary cameras that can be positioned to whatever viewpoint you choose. You can record out the side of the vehicle or within the passenger compartment, according to your own needs. It can also be used for security, angled specifically toward valuable equipment or cargo in the vehicle.
Camera Visibility in Your Vehicle
Dash cams are available to suit most needs. These needs may include an inconspicuously sized dash cam mounted in the windshield, one less visible to passers-by. These cameras are less prone to raising risk for vehicle break-in or vandalism.
If you want a discrete dash cam, some models are so small and hidden from view that people outside of the vehicle either cannot see the camera or are unaware that it is a camera device. Many of these position on the windshield behind the rear view mirror.
If you simply prefer an unobtrusive, small and non-distracting dash cam, many miniature models are available on the market to suit this need. These dash cams do not necessarily sacrifice features or functionality, either. Many small dash cams still have built-in screens and other capabilities, albeit at smaller size.
Of course, if you prefer a large LED screen for video playback in your vehicle, many dash cams feature three-inch screens or larger. If you have a substantially-sized, expensive or highly visible dash cam, most insurance companies and security experts recommend taking the cam out of your vehicle as you would your cell phone or wallet.
Quality of the Dash Cam’s Video Footage
Do you want to see every detail in high definition video, or do you simply want a “bigger picture” view of what happens on the road? Most cameras today provide great quality. But dash cam video quality still varies enough from camera to camera that you must consider what quality you need.
Some models of dash cams feature standard video quality at 480p to a higher quality at 720p. For high definition review of footage, such as on an HD video screen or television, you will want HD 1080p or the highest possible quality on today’s market, at Super HD 1296p.
Remember that the higher the quality, the better your video detail. If you want to read vehicle makes, models and license plate digits, you need high definition of at least 1080p. Night video quality is better at high definition, too. But of course, higher definition equals higher cost.
GPS Location Tracking
Many new dash cams provide GPS vehicle position logging. Many of these models also feature speed tracking through the built-in global positioning system, too. This capability means your video playback provides Google mapping of your vehicle adjacent to the video display.
Benefits of GPS logging include fleet vehicle tracking, court defense against inaccurate speeding tickets, proving your whereabouts at particular times and accident detail. These GPS systems either include a built-in antenna as part of the camera body or GPS signal receipt through external antenna and cabling. External cabling and antennas work much like a satellite radio system does.
Optional Turn-By-Turn Navigation
Dash cams today provide many optional features, such as navigation. This means you can let your smartphone or GPS rest and rely only on one device for recording video and providing turn-by-turn instructions. This navigation works like your smartphone app or other vehicle GPS system. You simply enter an address as the destination and let the device do the rest, providing both audible and mapped visual directions.
This type of dash cam enables you to remove the windshield or dash-mounted navigation system. It reduces the number of devices obstructing your view or cluttering the car.
Business or Fleet Vehicle Use
If you are using your dash cam for business, you want a model adequate for meeting your specific needs. A business dash cam is usually dual-channel, meaning two camera views. One camera records video through the front windshield, showing the vehicle’s path and maneuvers. The other camera usually records into the passenger cabin, showing the driver and vehicle occupants.
Some dual channel dash cams feature tamper-proof casings and mounts. This means the camera cannot be disabled or disconnected. On these professional dash cams, memory cards cannot be removed or erased. Some of these dash cams also provide remote tracking, so the vehicle owner can keep up with the vehicle’s location at all times.
Memory Card Capacity
How long your dash cam records video relies on the capacity of storage on the memory card. After the memory card is full, most dash cams loop the video and overwrite older footage.
Dash cam memory card quality is measured primarily by write speed and capacity. Write speed determines the memory card class, with that class being rated as 1, 2, 4, 6 or 10. A higher class card writes data at faster speed and provides better quality of video playback, among other benefits. So you should aim for a class 6 card or a class 10.
How many hours of video your memory card can hold is determined by its gigabytes, known simply as “GBs.” An 8GB memory card will hold two to three hours of video before looping the recording and overwriting older footage. A 16GB card provides four to six hours of consecutive recording. For six to 12 hours of recording you need a 32GB card. A 64GB card provides 10 to 20 hours of recorded footage before looping and a 128GB card provides between 20 and 40 hours. All of these times are for HD recording. For standard definition video of up to 720p, these recording times double.
A commercial truck driver or fleet vehicle owner benefits from longer spans. A typical personal vehicle driver may not need to store more than mere minutes’ worth of footage, particularly if the camera just serves accident recording purposes. How long you need your memory card to record depends on the purpose of your recordings. Remember that many dash cams only work with memory cards up to a particular capacity. This means that it does you no good to buy a 128GB memory card, if your camera only accepts cards up to 32GB.
Temporary or Permanent Dash Cam Installation
Some people are okay with temporary dash cam setups, using power cables leading to a cigarette lighter or other power outlet. Other people prefer no power cables show and want a sleek, clean appearance to their vehicle’s devices. If you want permanent installation without power cords left dangling, you can install your dash cam using vehicle power system access. Of course, running off your vehicle’s switched power system means your dash cam only operates when your car is running. But this method of permanent installation frees your cigarette lighter power outlet for other purposes.
WiFi Connectivity for Your Dash Cam
WiFi is an important feature for many devices today. Your dash cam is no different. Having WiFi connectivity means your dash cam syncs to your phone, tablet or other devices. This provides important functionality, such as using your phone, laptop or tablet as a video screen accessing and controlling the dash cam.
Having WiFi connectivity also typically enables you to watch and download your dash cam videos. You can change the camera’s settings using smartphone or tablet apps. When you want to share videos from your dash cam on social media or as shared video, being WiFi enabled allows this.
WiFi connection is particularly important after an auto accident or other insurance claim incident. You can easily share dash cam footage with your insurance company, law enforcement officers or others, whether through email, video sharing services or on social media.
Using the dash cam’s WiFi app usually does not require connection to a cellular data plan or provider. Many dash cams have cloud capabilities enabling you to link your camera to an internet service provider or hotspot for full features. These connections enable some dash cams to provide live streaming, location tracking and important alerts, such as if someone hits your parked vehicle. Under these circumstances, WiFi connection is like having your eyes on your vehicle and its immediate surroundings at all times.
Important Dash Cam Specifications and Features to Consider
Regardless of your dash cam purpose, there are certain important features to consider when buying your camera and accessories. The most critical features for dash cam shoppers include:
Video resolution, with most purposes requiring at least 720p and best detail seen at 1080p or above
Storage capacity, with best use at 64GB or higher
Night vision, since many accidents occur at night
Secondary to these critical features are the below needs many people buying dash cams consider important:
Automatic on and off, starting with your car and turning off when your car is at rest
Camera size, not blocking your field of vision or causing distraction
Loop recording, to continue recording by overwriting older, unneeded footage
Below are useful attributes for your dash cam that you may or may not need:
Impact sensor or G-sensor, detecting accidents or other impact with your vehicle to automatically record when these incidents occur and even when parked
GPS to accurately provide vehicle location, speed and other defensive information
Dual cameras, for recording of the front field of view and either inside the vehicle or behind it
Built-in mounting, to ensure your dash cam is stable on the windshield or dash instead of being loosely positioned in the vehicle
WiFi enabled, to unlock all of the smartphone and other device connectivity and applications available for your dash cam
Frequently Asked Questions about Dash Cams
What is the dash camera’s recording resolution?
For best replay and detailed data capture, look for a minimum of 1080p resolution.
How many frames per second does the dash cam record?
A good dash cam records video at 30 frames per second, but also may provide other options at a slower speed to take up less recording space.
Are there varying recording modes, such as motion-detection or automatic monitoring?
A great option for dash cams is G-sensor or parking monitor mode, to activate recording if your parked vehicle is hit.
Does the dash cam manufacturing company gain positive customer service reviews?
Some companies provide excellent service, while others receive lots of complaints.
Does the camera work in varying lighting?
Night recording capability is important if you drive after dark or in inclement weather.
Does the camera mount on the windshield or the dash?
Most dash cams actually mount on your windshield today, behind or adjacent to your rear view mirror.
Is the camera suited to intense heat or cold weather operation?
Both cold weather and hot weather affect everything from the camera’s adhesive grip on your windshield, to melting parts from direct sun. You need a dash cam showing it works at extreme temperatures, like the KDLINKS DX2 Full-HD 1080P Front + 720P Rear Dash Cam.
How is the camera mounted and does that mounting damage the car’s interior surface?
Most dash cams today use an adhesive mount on the windshield. This method usually causes no harm to the vehicle’s interior.
For capturing clearer perspective around the vehicle, what is the field of view in degrees?
A 180-degree dash cam field of view provides a full scenic view in front of the vehicle or behind it, to its sides. But with the 180-degree view vehicles directly in front of the camera appear farther away than they really are. A 140-degree field of view is still broad, but alters vehicle distance perception less.
Is a memory card included, and if so what capacity is the memory card?
32GB is the optimum memory card length for a loop recording dash cam. Less GB means the recording must loop in shorter sequences or you need to record at lower quality. For someone who drives long distances or records for long periods, optimum size may be 64GB or even higher.
Is the dash cam compatible with other devices?
You need to decide whether you want to perform extended dash cam actions on your smart devices, in your car or on a device outside of the vehicle. Most people find greatest convenience in having a dash cam that is WiFi enabled to work on its own, as well as from an Internet enabled smartphone, tablet or computer.
Does the dash cam feature its own footage review screen or must footage be reviewed on a compatible device?
Having a 2-inch or larger screen on your dash cam makes reviewing footage in the vehicle much easier. Some dash cams feature 3-inch or larger screens.
If the camera features safety warnings, such as lane departure or forward collision alerts, can these be deactivated if desired?
Some people find the alerts annoying, while others feel safer with these alerts. You may change your mind when using your dash cam, so you need the ability to toggle them on or off.
What is the maximum GB size compatibility for memory cards?
Some dash cams only work with memory cards up to 16GB. Others allow 128GB or more. If you need to capture lengthy footage or high quality video for detailed data, having the ability to upgrade to 64GB or more is important.
Is there a product warranty and what is the company’s exchange and return policy?
As dash cams are electronic devices, they can malfunction. Having a warranty, exchange policy and return policy is important.
Can the monitor video screen be disabled to prevent distracted driving?
Some drivers are distracted by the video monitor screen. Being able to turn the screen off during camera operation helps prevent accidents, for these drivers.
Can you change the camera’s recording resolution to enable lengthier recording on the memory card?
Sometimes you need detailed data, like the ability to read license plates should an accident occur. At other times you only want to enjoy the views from your windshield. Having a camera enabling variable resolution means you use less of your memory card when you do not need sharp detail.
What size is the camera’s video playback screen?
Two-inch or three-inch dash cam video screens are best, if available. These are large enough for great video review, but small enough that they are not distracting.
Does the camera auto-lock or is there a manual locking function to prevent overwriting of recorded incident video?
When you suffer an accident or another incident is captured on video, you need that footage secured so the device does not accidentally overwrite it. This means you need either an auto-lock or manual locking function to prevent video looping.
Does the camera feature the ability to take and store still photographs of accident damage or scene evidence?
If you are in an accident, having a dash cam that takes scene and damage photos means you can securely document damage for your insurance company, police, and legal case.
Are there additional subscription features available on the camera, such as speed camera locator service?
Having the ability to subscribe to apps or features means your dash cam gains additional capabilities. Consider whether individual features are worthwhile when comparing cameras to find your best fit.
Does the camera record audio and video, or just silent video?
Sometimes you need sound on your video, to gain a full picture of events. If you are recording the interior of your vehicle, this is particularly important. Be sure you make this decision and buy the camera best suited to your preferences.
Are replacement parts available for the camera mount, or are third-party mounts usable?
Sometimes camera mounts melt in hot sun, break or malfunction. Some shoppers have found that third-party mounts work even better than those provided by the manufacturer.
Are wiring connections easy-to-use and functional for ongoing use?
The last thing you may need in your vehicle are more wires to cigarette lighters and ports. For a dash cam you only use on special occasions, having a wire is likely not bothersome. But a dash cam used for every outing should be out of your way and functional, with wires neatly tucked away or connected out of sight.
Are the camera and its parts guaranteed or supported by the reseller?
Resellers sometimes fix problems manufacturers will not. Such is the case if you buy a dash cam and receive a broken or damaged one. The reseller may take care of this problem, dealing with the manufacturer for you.
Does the camera feature a G-sensor as incident detection for automatic activation?
A G-sensor wakes the camera and starts recording when something collides with your car or bumps against it. Having footage of these incidents makes the difference between solving a hit and run and not solving it, or gaining insurance compensation or having to pay for damage yourself.
For dual or rear-facing cams, does the rear-facing camera feature adequate night vision for usability at night?
Many rear facing cams lose night capabilities because of headlights of oncoming vehicles or the sheer darkness of the unlit road behind your vehicle. Night vision or light adjusting dash cams fix this problem.
Can the G-sensor be deactivated if it is sensitive to car door or trunk closing?
You do not need your dash cam to record every time you shut a door or close your trunk. If it is too sensitive and wastes video memory, it is very helpful to have the ability to turn this sensor off.
Does the dash cam provide navigation or turn-by-turn directions, if desired?
Having one less windshield or dash-mounted device is helpful, if you need GPS mapping as well as dash cam recording. Some dash cams feature these options and solve the problem of too many devices and wires.
Does the dash cam provide tamper resistance for parental, fleet management or business use?
If you have other drivers using your vehicle, locking your camera may be important. A lock means the camera can only be disabled or footage overwritten by you.
