When I first set up my Wyze Cam v4, I knew I wanted to take advantage of the local storage options. After all, having footage stored right on the camera just feels more secure than relying solely on cloud services. But I had a lot of questions about how the SD card works with the Wyze Cam v4. If you’re in the same boat, wondering “How do I use an SD card with my Wyze Cam v4?”, you’re in the right place. In this guide, I’ll walk you through everything you need to know, from compatibility to recording options and troubleshooting.
Key Points to Know:
- Wyze Cam v4 supports microSD cards up to 256GB.
- You can use continuous or event-based recording with the SD card.
- Proper formatting and maintenance are key for reliable local storage.

Why Use an SD Card with Wyze Cam v4?
One of the great things about the Wyze Cam v4 is that it gives you the flexibility to store footage locally on an SD card. This is a game-changer, especially if you live in an area with spotty internet or want to avoid the recurring costs of cloud storage subscriptions.
With an SD card, you can set your Wyze Cam v4 to record 24/7 without worrying about bandwidth or losing footage if your Wi-Fi goes down. It’s like having a built-in DVR system that’s always there, ready to capture important moments. And if you need to review something specific, you can just pop out the card and plug it into your computer.
SD Card Compatibility for Wyze Cam v4
Okay, let’s talk about the technical stuff. The Wyze Cam v4 supports microSD cards up to 256GB in capacity. I’d recommend sticking to high-quality, Class 10 or UHS-1 cards for the best performance. Brands like SanDisk, Samsung, and Kingston are all great options.
The camera can work with cards formatted in either FAT32 or exFAT file systems. If you’re not sure which one to use, the Wyze app will guide you through the formatting process, so don’t worry too much about that part.
How to Install and Format an SD Card
Installing the SD card is straightforward. Just locate the slot on the side of the Wyze Cam v4, gently insert the card, and you’re good to go. The hard part is making sure it’s properly formatted, so let me walk you through that:
- Open the Wyze App: Find your Wyze Cam v4 in the app and tap on the settings gear.
- Go to Advanced Settings: Scroll down until you see the “SD Card” option.
- Format the Card: Tap “Format SD Card” and follow the on-screen instructions.
Formatting ensures the card is compatible with the camera and prepares it for optimal performance. Trust me, taking the time to do this right will save you a lot of headaches down the line.
Recording Options with an SD Card
Once you’ve got the SD card all set up, you’ve got two main recording options to choose from:
Continuous Recording
This mode records footage 24/7, overwriting the oldest clips when the card is full. It’s great if you want comprehensive coverage and don’t want to miss a thing. The downside is that it can eat up storage space quickly, so you’ll need to keep an eye on the card’s capacity.
Event-Based Recording
With this mode, the camera only records when it detects motion or sound. That means you’ll have a more streamlined timeline of important events, making it easier to find what you’re looking for. It’s also more storage-efficient, as the camera isn’t constantly recording.
Recording Mode | Description | Best For |
---|---|---|
Continuous Recording | Records all the time, overwriting old footage | Maximum coverage |
Event-Based Recording | Records only during motion or sound events | Storage efficiency and quick reviews |

Accessing and Playback Footage
Viewing the footage stored on your SD card is a breeze. Just open the Wyze app and head to the “Playback” tab. You’ll see a timeline of all your recordings, which you can scrub through to find the exact moment you’re looking for.
If you need to access the files on your computer, simply remove the SD card and use a card reader. The camera saves the footage as standard video files, so you can play them back on any media player.
Maintaining Your SD Card
To keep your SD card running smoothly, there are a few maintenance tips to keep in mind:
- Format Regularly: Every few months, use the Wyze app to format the card. This helps prevent errors and corruption.
- Use High-Quality Cards: Stick to reputable brands and avoid cheap, off-brand SD cards.
- Keep It Clean: Gently wipe the card contacts with a clean, dry cloth before inserting it.
If you ever notice issues like missing recordings or playback problems, those could be signs of a failing card. In that case, it’s best to replace the SD card to avoid data loss.

Troubleshooting Common SD Card Issues
Even with the best care, sometimes things don’t go as planned. Here are a few common SD card problems and how to fix them:
Issue | Solution |
---|---|
SD Card Not Recognized | Reinsert the card or format it in the app. |
Corrupted Files | Format the card and use a high-quality brand. |
Full Storage | Use event-based recording or upgrade the card. |
The key is to stay calm and methodical. Nine times out of ten, a simple format or card replacement will do the trick.
SD Card vs. Wyze Cloud Storage
Now, you might be wondering, “Should I use an SD card or just go with Wyze’s cloud storage?” It’s a valid question, and the answer really depends on your needs and preferences.
The main advantage of an SD card is that it’s a one-time cost and gives you local, offline access to your footage. Cloud storage, on the other hand, requires a subscription but offers the convenience of accessing your videos from anywhere.
Feature | SD Card Storage | Cloud Storage |
---|---|---|
Cost | One-time purchase | Monthly or annual subscription |
Accessibility | Local only | Accessible from anywhere |
Storage Capacity | Limited by SD card (up to 256GB) | Unlimited (with subscription plan) |
Personally, I like having the SD card as a backup, but I also appreciate the flexibility of the cloud. You might find that a combination of the two works best for your home security needs.
