What are SD Cards and What Video Storage Do I Need?

Let's start with the basics to get you informed

Which SD card is right for me?

When buying a dash cam system for your vehicle, many people tend to forget one hugely important item: the microSD card. MicroSD card usage in a dash cam is so vital because some cards fail very quickly and you may lose crucial footage in case of an accident. In our experience, the best micro SD card for dash cams are high capacity cards that are Class 10 with MLC technology, which basically translate to fast download and upload cards with added durability.

Speed Rating

When we talk about Class 10 and MLC rating, we’re referring to the speed rating of the SD card.

Class 10 is a class of rank on the write speed of the SD card; the number 10 stands for 10 megabytes per second. Generally, what we see with the more “affordable” cards are slower read (download) and write (upload) speeds. This leads to recording issues or literal skips in the recording.

On average, 2-channel dash cams write 16GB/hour and 1-channel dash cams write 8GB/hour.

Having a reliable, fast, and durable SD card can help ensure that you’re always protected. That being said, “faster SD cards” won’t necessarily improve video quality nor durability. Remember that dash cams don’t require the highest speed rating - rather, they require durability.

The best MicroSD cards to use for your dash cam should be at least a class 10 rank for speed and durability

Memory Size

The amount of space is important for your everyday dash cam use. However, the size of SD cards may vary depending on your use of the dash cam.

Best for Driving Recording

A 32GB card is great for value for those who use their dash cams for driving recording. Typically this translates to about 3-4 hours of 1080P recording, which is more than enough for most drivers. Any less and you pay more money per gigabyte and save only a few dollars.

Best for Parking Mode Recording

If you’re using a parking mode dash cam, a 64GB size and higher improves durability and gives you extended parking recording.

Best for Rideshare Recording

Rideshare drivers may want to use the larger 128GB card so as to keep the most amount of video storage in case of any issues with previous customers. These cards are significantly more expensive per gigabyte but most find them to be of value.

Our most popular cards are the 128GB option, since most customers prefer the peace of mind that footage won’t be overwritten so quickly. In addition, memory partition feature separates video files based on the recording to offer you additional forms of protection.

Recording Capacity of SD Cards

How much video can an SD card hold?

This is a question we get all the time and the answer depends on two factors: the SD card size and the dash cam's bit rate.

Backup SD Card

In addition, we recommend all of our customers to purchase a smaller 16GB or 32GB card to be kept in your vehicle at all times. The reason is because they can be used in case your SD card in the unit fails or you’re away on a trip and won’t be able to save or review the footage in time before it gets overwritten.

You’ll be able to swap your cards out instantly and keep recording without worrying that important footage will be deleted.

Which SD Card Should I Buy?

BlackboxMyCar is proud to say that all the microSD cards we offer have been rigorously tested to ensure compatibility and to offer the longest lifespan as well. We carry cards by the dash cam manufacturer, such as BlackVue and Thinkware, as well as our own branded micro SD cards, which perform flawlessly as well.

Our third-party microSD cards go through the same quality testing and are a more affordable option for SD card options. No matter what card you buy from us, all of these are covered under an in-house warranty so you can be rest assured that we’ll resolve any issues that you may come across.

Awesome Rideshare Setup!

First of all! Very nice and knowledgeable people at blackboxmycar! Second very nice setup with power magic pro wiring kit! Also very discrete design! Love the video quality! Especially at night with the Sony Starvis! Overall good setup! Can barely see the cams. Thanks again Blackboxmycar.com/BlackVue!!! 👍👍👍

Very Good - not yet great. But getting there.

I purchased the BlackVue DR900S 2 channel with interior facing IR after an attempted theft of my 2019 F-150 Lariat. It was already a purchase I had been considering in order to add a layer of security during both active and passive vehicle usage and I didn't hesitate to go with BMC given the number of positive reviews.

After a fast and painless exchange via email, BMC matched a lower price point offer for the kit that I had found on the internet. BMC even included a slightly larger storage card. Shipping and receipt went smoothly.

If I can fault BMC it is in the install and "commissioning" of the dash cam. Though I had done a fair bit of research and certainly am not one to shy away from peeling off some trim or crimping some wires, there was no step-by-step guide to installation that would have given an illustrated and comprehensive explanation of the process; now, this information exists and I was able to access it, but it was still a bit of a patchwork construction and an installation that I thought might take one hour took 2 days.

All said, though, the system is now up and running, so far flawlessly, in my vehicle. There has been a lot of trial and error, but the dash cam community is helpful and all of the information is available. You just need to look for it.

I will post a video review of my installation shortly - including hardwired battery installation.

Hi Alexander, thank you for leaving a review! We're glad to hear that we were able to help you with your order. You brought up some great points, and we will definitely take your feedback to heart for the future. We hope that the dash cam works out for you. Please let us know if you have any questions in the future.

BlackboxMyCar Add-A-Fuse Kit

Hi Brian, thanks for leaving a review!
VIOFO A119 12V Auto Hardwire Kit

Quality hardwire kit with reasonable length to the A119 and to the 12V battery source. Voltage reducer is small enough to fit in small spaces with rounded corners for ease of fishing into place. Fuse holder streamlined but difficult to open at first, 2nd time ok.

Hi Chester, thanks for leaving a review! Glad to hear that you were able to figure it out and install your VIOFO. Let us know if you have any questions. Thanks!
the ONLY place I can find this replacement part online

Blackboxmycar is the only place I could find that sells the cigarette socket power output cable for the Cellink Neo.
Fast shipping. Item as described.

Hi J. Kim, we're glad to hear you were able to find what you were looking for at our store. Thanks for shopping at BlackboxMyCar!
Great Kit- Everything you need

Hi Jennifer, thanks for leaving a review. We're glad to hear that you have found everything you need in our Essential Installation Kits. Thanks!
Suction Cup add-on

I bought this suction cup mount to move and use quickly my A119 V3 from vehicle to vehicle.
After receiving I must say its smaller and lighter than expected compared to the picture but still functional and we will see how long the suction cup lasts over time.
I also saw a video of using this suction cup to turn the A119 around and take video of driver with commentary about area or something else which I plan to edit into my video at a later time.
So its a nice feature for the video I plan to make while on vacation.
Cool!

Hi John, thanks for your feedback. Let us know if the suction cup mount doesn't work well for you over time and we'll try our best to help. Thanks!
Blackbox My Car is the Best!

Sorry BB team for taking so long before writing a review, but the 2 Viofo a129 duo dashs were xmas gifts and I wanted to wait for your professional installations to be done first.
I have purchased dascams from BB before and have had nothing but a great experience for both service and products.

Both Viofo cams are working great and the installation service was the best. The team was awesome and answered all my questions without hesitation. Your waiting area and amenities are first class. Most car dealerships could learned a thing or 2 from how you operate!

Thank you again!

Hi Ken, appreciate your compliments and thank you for leaving a review! We're glad to hear that you enjoyed our facilities and that the installation and the dash cams worked out for you. If you have any questions, please don't hesitate to reach out at any time in the future!
Very pleased with the A119V3 and with customer service

After researching a number affordable dash cams I settled on the Viofo A119V3 and Blackboxmycar as the vendor. I chose Blackboxmycar because of its customer service. This is my first Dashcam and I had a number of questions all of which were answered promptly and to my satisfaction by Katrina. Other vendors offered a slightly less expensive final cost but Katrina's service swayed my decision.

As to the camera itself I am very happy. In the last few days I have used it in temperatures of about -28ºC and it has performed flawlessly. The video quality is excellent with the CPL: clear, sharp and with good colours and contrast. Files are around 1.15 GB for 5 mins using 2560x1440 @30 fps H.264 or around 950 MB using H.265. The audio quality is quite acceptable.

Once you get the hang of using the Menu system it is quite easy to choose or change settings.

Also impressed with Viofo in that they seem to have thought of everything. The item included everything I could possibly need to mount and operate the camera even down to string to help remove the mounts in future if necessary.

Presently I am powering the camera via the cigarette lighter but am seriously considering hardwiring or using a portable power bank. I will then try the parking modes.

We have two cars and I had thought of moving the camera from one to the other so I purchased an additional GPS mount, that I have not yet tested. However I am now leaning towards buying 2nd A119V3 to avoid the hassle and to have a permanent neat installation in both cars.

Hi David, thanks for leaving a review! We're glad to hear that Katrina was able to help you out, and that the VIOFO A119 V3 was exactly what you were looking for. If you need anything else, please don't hesitate to let us know!

Best Site for the Best Dashcams Around

My 2nd purchase from Alex and 2nd Blackvue camera purchased. Blackvue is my favourite dashcam because of its sleek and unobtrusive design and extremely high quality recordings. Easy to download recordings with the app now, will continue to recommend Blackvue's to everyone.

As for blackboxmycar.ca, great selection of the best Dashcams out on the market. Extremely informative website with an abundance of information and comparisons to make the right choice. Fast shipping and great customer service, this is the way to go to buy a dashcam over the cheaper but inferior choices on Amazon or anywhere else.

Hi Wesley, thanks for your review. We're glad to hear that you're loving your BlackVue dash cam as much as we do! Hope the DR590W-1CH treats you well :) If you have any questions, please don't hesitate to reach out to our team.

1st time buyer from BlackBoxMyCar.com

Review Title
I have done a lot of research on finding my second dash cam and decided on a VIOFO A119 V3.
I have seen some video of reviews of the camera and compared to my 1st Dash Cam A119S V2 and figured that VIOFO was a good choice again. I have seen Alex the CEO of BlackBoxMyCar do a review video on the A119 V3 in 2019 and went to his website and decided it was very professionally designed and easy to use. Not only did I buy the camera I found some accessories.
I ordered then noticed they offered first responders and military a discount and sent an email if I could get this discount. Quick email reply from Paul who I sent documentation on proof and he who forwarded my request to get a refund on my purchase. Thank you.
Now I did order my camera knowing it was back ordered as well as this was Christmas and New Years week so I wasn’t expecting to see the camera until Jan 2020.
It did arrive in a box and was properly packed. I had numerous email from FedEx where my package was and when it would arrive and someone must be home to signature for it.
Between the initial purchase and receiving my dash cam BBMC has been above and beyond what I expected and under the leadership of Alex I see why this company is so successful.
Thank you everyone for a great purchase and plan on additional future purchase from me.

Hi John, thank you for the kind words and the detailed review. We're glad to hear that we were able to help you find what you're looking for. We will pass on your compliments to Alex who will absolutely be delighted to read this. Thanks again, and do let us know if you have any questions.
Delivery Needs To Be Improved

I ordered it on Dec 28 with Rocket shipping and it arrived Jan 6 but I had to constantly contact them about the status of the order as it was stuck for many days with no updates. I give this service 1 star. The product itself is excellent, well made (except the App), easy to install, etc which deserves 5 stars. Overall 3 stars.

Hi Bill, thank you for leaving a review. We do want to apologize for that, and thank you for your patience. This holiday season was quite a busy one for our team, and we had some inventory delays with the unexpected surge in demand for our battery packs. We are working on smoothing that out moving forward so that we don't have this happen again. From a communication standpoint, we will absolutely work on fixing that moving forward to make sure our customers are aware of any delays. We apologize for the inconvenience. Thank you for purchasing from BlackboxMyCar, and if you have any questions, Bill, please don't hesitate to reach out to our support team.
Great for extended parking mode!

Before purchased and installed the Cellink Neo I was using my Thinkware Q800Pro hardwired to my car. However, my vehicle stays parked for days on end without me having to drive anywhere. I get about 40 hours with a dual camera setup, and I couldn’t be happier to have an extra piece of mind. The installation was very easy, as I did it myself (hardwired) and mounted it under the driver seat. This would be a worth while purchase.

Hi Brandon, we're glad to hear that your new battery pack worked out for you! If you have any questions, please don't hesitate to contact us in the future.

Although my dash cam was on a backorder after Christmas, it delivered right the way I wanted it. I like the dash cam is tiny. The video is very clear.

Hi John, thank you for leaving a review. We had some inventory delays during the holiday season with the unexpected surge in demand for our dash cams, but we're glad that we were able to deliver your dash cam in time. Thank you for purchasing from BlackboxMyCar!
Great product to reduce glare!

Does what it says to reduce windshield glare, it’s easy to install

Hi Brandon, thank you for leaving a review! If you have any questions, please don't hesitate to contact us in the future.
Amazing Product - Worth Buying

This product helped hardwiring my dash cam so much easier as there were no wires that needed to be spliced. The trim tool made it convenient to tuck the wires inside the car and only show minimal wires. All in all, this all-in-one kit, made hardwiring my dash cam so much easier.

Hi Sai, thank you for leaving a review and for shopping at BlackboxMyCar. Glad to hear that this worked out for you. Please don't hesitate to reach out to us in the future if you have any more questions.
