Dash Cam & Security Camera Memory Cards

Learn more +

Shop reliable memory cards for dash cams, home security cameras, body cams, fleet vehicles, and 24/7 monitoring systems in Canada. This collection focuses on endurance-rated microSD cards built for continuous recording, frequent overwriting, and dependable footage capture when reliability matters most.

For loop recording and surveillance use, endurance matters more than choosing the cheapest card. High Endurance and MAX Endurance models are built for repeated video writing, while the right speed class and capacity help reduce dropped footage, early wear, and unnecessary card swaps. If you need help choosing, start with 128GB for many everyday setups and move to 256GB+ for longer retention windows, heavier use, or 4K-capable systems.

Top Select Canada offers authentic SanDisk storage, fast Canadian shipping, and bulk quote support for installers, security teams, institutional buyers, and repeat deployments.

Frequently Asked Questions

What is the best type of memory card for a dash cam?

An endurance-rated microSD card is usually the best choice for a dash cam because dash cams record in loops and continuously overwrite older footage. That creates much more write wear than normal photo or file storage.

Do security cameras need endurance microSD cards?

In many cases, yes. Security cameras often record continuously or very frequently, so endurance-focused cards are better suited to long-term reliability than general-purpose cards.

Is U3 or V30 necessary for a dash cam or security camera?

Not always, but for many 4K-capable systems U3 / V30 is the safer option. The right speed depends on your camera’s recording bitrate and resolution. If you need help decoding symbols, read: SD card symbols explained.

Is 128GB enough for a dash cam?

For many drivers, yes. A 128GB card is a strong starting point because it balances cost, compatibility, and footage retention. If you drive long hours or use 4K recording, 256GB may be a better fit.

What is the difference between High Endurance and MAX Endurance?

High Endurance is a strong fit for many everyday dash cam and home monitoring setups. MAX Endurance is the better choice for heavier-duty, longer-running, or more demanding continuous-recording environments.

Can I buy dash cam memory cards in bulk for my business?

Yes. If you are buying for fleets, installers, security teams, or repeat deployments, use the bulk quote page for business pricing and project support.

How can I avoid counterfeit memory cards in Canada?

Buy from authorized Canadian sellers, avoid listings that look unusually cheap, and verify the card after purchase. Buying locally also helps with warranty support, returns, and avoiding surprise import costs. Read more here: why buying in Canada matters.

What should I do if my memory card becomes corrupted?

Stop using it immediately and avoid writing new files to it. In many cases, files can still be recovered if you act quickly and follow safe recovery steps. Use this guide: recover files from a corrupted memory card.
