What good is your security camera if the MicroSD card based storage isn’t reliable? In 2025, with 1080p, 2K, and now even 4K footage becoming standard across home and business security systems, you will need the best microSD cards for security cameras. Choosing the wrong card can lead to corrupted video, lost recordings, and premature wear — a problem no homeowner or business wants to face.
For brands like Blink, Reolink, Eufy, Wyze, and Arlo, which offer flexible options for local storage, the right MicroSD card ensures continuous recording, smooth video playback, and long-term durability. Security cameras record all day long. So, the microSD cards running in them should handle the load.
At BulkMemoryCards.com, we provide high-endurance MicroSD cards that can withstand the constant demands of security applications. And for organizations that need to purchase at scale, our wholesale pricing and fast shipping help ensure you’re always stocked with the best storage at the best value.
Best MicroSD Cards for Security Cameras
The SanDisk High Endurance 128GB MicroSDXC remains one of the most reliable options for continuous security camera recording. The SanDisk High Endurance microSD card’s sole purpose is to go in security cameras and devices that write constantly. So it can handle thousands of hours of 1080p video writing without failure. With compatibility across Wyze and Ring, this card offers dependable performance for budget-conscious users without compromising quality.
If you need more capacity and plan to install cards in outdoor or high-use environments, the Samsung PRO Ultimate 256GB MicroSDXC is a standout. This card is a great fit for Arlo cameras using SmartHubs or any Wyze outdoor system. The Samsung PRO Endurance series has become a go-to among installers thanks to its extended lifespan and fast write performance.
For users seeking high-speed write access with full V30 certification, the SanDisk Max Endurance 256GB MicroSDXC delivers excellent value. This card is rated for high-resolution video applications and is well-suited for Arlo and Ring systems that benefit from rapid access to recorded clips.
Lastly, the SanDisk Extreme 128GB MicroSDXC provides solid performance for indoor security cameras using motion-event storage. While it may not match the endurance of the top-tier models, its affordability makes it a smart choice for low-traffic locations or temporary installations. It’s also available in higher capacities for longer retention periods.

Why Security Cameras Demand High-Endurance MicroSD Cards
Security cameras aren’t like action cams or smartphones. They don’t record once, save the file, and move on. They often record 24/7, constantly overwriting old footage in a loop. This non-stop write activity wears out traditional MicroSD cards quickly. That’s why endurance-rated cards, built specifically for surveillance workloads, are essential.
High-endurance MicroSD cards are designed to handle tens of thousands of write cycles without failing. They also operate reliably in extreme temperatures. When choosing a card, it’s not just about capacity — write speed, durability, and brand reliability all factor into how well the card performs in a security setting.
If you’re installing multiple cameras across a building, parking lot, or property, investing in dependable MicroSD cards is just as important as selecting the right camera model.
MicroSD Card Specifications for Blink Cameras
Blink, an Amazon-owned brand, is a go-to choice for affordable, battery-powered smart cameras. One of the leading features of Blink is the up to 2 year battery life! While most Blink cameras rely heavily on cloud storage by default, models like the Blink Outdoor 4 and Blink Mini 2 offer the option of local video storage through the Blink Sync Module XR, which includes a microSD card slot. None of the new Blink cameras have a microSD card slot directly in the camera. However, many users still refer to storage as “microSD-compatible” when discussing local options.
Here’s what to consider when choosing MicroSD storage for a Blink setup:
- Format: exFAT
- Max Capacity: 256GB for Blink Sync Module XR
- Speed Class: Class 10 or UHS-I
- Recording Mode: Motion-based event storage only
- Environment: Indoor and outdoor
Since Blink does not support continuous recording, the data write volume is lower compared to other brands. Still, you will need a quality, high-endurance MicroSD card so that event clips are stored without error. You will view these through the Blink app. Using a card that’s too slow or not endurance-rated can lead to missed events or corrupted files.
If you manage properties or multiple camera setups using Blink devices and Sync Modules, purchasing microSD cards in bulk from our website will save you money!
MicroSD Card Specifications for Reolink Cameras
Reolink has gained strong traction among homeowners and small business owners thanks to its high-resolution IP cameras and local storage capabilities. Many of its wired and wireless models support continuous 24/7 recording directly to MicroSD cards, making them a flexible and cost-effective choice for users who want to avoid cloud fees. Popular Reolink models like the Reolink Argus 3 Pro include a microSD slot.
To get the most out of Reolink’s recording capabilities, here are the MicroSD requirements:
- Format: exFAT
- Max Capacity: 128GB (on most models; newer units support up to 512GB)
- Speed Class: Class 10 or UHS-I
- Recording Mode: Continuous and motion-triggered
- Environment: Outdoor
Reolink recommends using high-endurance MicroSD cards, especially for models set to record 24/7. These cards need to survive extreme temperatures, constant writes, and exposure to the elements. Because many Reolink installations involve multiple cameras monitoring outdoor spaces, storage reliability becomes essential. Customers ordering a dozen or more cameras will benefit from buying cards in bulk, reducing cost and eliminating compatibility headaches.
For customers sourcing microSD cards for a property-wide security system or a commercial install, our website offers fast-shipping, high-capacity MicroSD cards compatible with all Reolink models.
MicroSD Card Specifications for Eufy Cameras
Eufy by Anker has built a strong following in recent years with its sleek, cloud-optional home security ecosystem. Unlike some competitors, Eufy has a couple of local storage-first solutions, including models like the Indoor Cam C120 and E220. They offer expandable storage via MicroSD or HomeBase storage hubs. Eufy’s microSD-enabled cameras are a strong choice for homeowners prioritizing privacy and offline control.
MicroSD cards for Eufy systems must meet the following requirements:
- Format: exFAT
- Max Capacity: 128GB (most current models)
- Speed Class: Class 10 or UHS-I
- Recording Mode: Motion-triggered event storage
- Environment: Indoor
Eufy typically records only short motion-detection clips instead of full-time footage, which reduces the total write load. Still, high-endurance cards are recommended, especially for busy entryways, driveways, or high-traffic areas. Eufy cameras are often installed in groups throughout a home — front door, backyard, garage — and each one requires its own MicroSD card. For families upgrading their entire security system or installers handling multiple homes, buying reliable MicroSD cards in quantity ensures everything works smoothly from day one.
At BulkMemoryCards.com, we carry Eufy-compatible MicroSD cards that balance speed, endurance, and affordability. Reach out today for a custom quote if you’re preparing for a multi-camera Eufy setup.
MicroSD Card Specifications for Wyze Cameras
Wyze continues to lead in affordable DIY security, with indoor and outdoor cameras offering 1080p and even 2K recording in their latest models. Many users choose Wyze cameras for their ability to record directly to MicroSD, which allows for continuous, local storage without monthly cloud fees.
For smooth performance and long-term reliability, Wyze recommends:
- Format: exFAT
- Max Capacity: up to 512GB
- Speed Class: Class 10 or U1 minimum
- Recording Mode: Continuous or Motion Event Recording
- Environment: Indoor and Outdoor (depending on model)
Because Wyze cameras are so cost-effective, many customers install them in bulk across homes, offices, and even farms. For these multi-camera setups, ordering endurance MicroSD cards in bulk through BulkMemoryCards.com keeps installation streamlined and affordable.
MicroSD Card Specifications for Arlo Cameras
Arlo offers some of the highest-quality footage among smart security systems, with models like the Arlo Ultra 2 recording in crisp 4K resolution. While much of Arlo’s storage system is cloud-based, their SmartHub allows users to back up recordings locally via MicroSD cards, offering an extra layer of redundancy and control.
To support Arlo’s 4K or 2K video recording, the following specs are required:
- Format: exFAT (FAT32 for some older hubs)
- Max Capacity: Up to 512GB supported
- Speed Class: U3 or V30 recommended
- Recording Mode: Continuous or Motion Event Backup
- Environment: Stored within the SmartHub (indoors)
Because the recording is done at high bitrates, a slow or generic card simply can’t keep up. Arlo recommends high speed cards to avoid dropped frames. If you’re outfitting an office park, church, or school campus with multiple Arlo SmartHubs, sourcing MicroSD cards from us gives you the capacity and performance you need at wholesale rates.
Final Thoughts
In 2025, modern security cameras from Wyze, Ring, and Arlo depend on fast, reliable, and high-endurance MicroSD cards to function properly. Without the right storage, even the most advanced camera will miss critical footage or suffer from performance issues. Lastly, by choosing cards built for surveillance you’ll extend the life of your system and capture the moments that matter.
Don’t trust your video footage to just any memory card. Equip your system with the best MicroSD cards for security cameras and enjoy long-lasting, trouble-free performance.
