Choosing the right size isn’t just about how much footage you can store—it’s about reliability, performance, and peace of mind.

Imagine this: you’re away on vacation, and your camera captures a break-in. But when you check the footage, the SD card was full, and the critical moment was never recorded. That’s why understanding what size SD card for Jennov Mini Bullet Camera is essential. It’s not just a technical detail—it’s your first line of defense in ensuring your security system works when you need it most.

In this guide, we’ll walk you through everything you need to know about selecting, installing, and maintaining the perfect SD card for your Jennov Mini Bullet Camera. From storage capacity and speed ratings to real-world recording times and top brand recommendations, we’ve got you covered. Whether you’re a first-time buyer or upgrading your current setup, this article will help you make an informed decision that keeps your property safe and your footage intact.

Understanding the Jennov Mini Bullet Camera’s Storage Requirements

The Jennov Mini Bullet Camera is designed for discreet, high-quality surveillance with support for local storage via a microSD card slot. Unlike cloud-dependent cameras, this model gives you full control over your footage—no monthly fees, no privacy concerns. But to take full advantage of that, you need to understand how the camera uses storage and what it expects from your SD card.

Supported SD Card Types and Capacities

The Jennov Mini Bullet Camera officially supports microSD cards up to 128GB in capacity. This includes microSDHC (up to 32GB) and microSDXC (64GB to 128GB) formats. While some users have reported success with larger cards (like 256GB), these are not officially supported and may lead to compatibility issues such as failure to format, corrupted files, or inconsistent recording.

For best results, stick to the 128GB limit. The camera’s firmware is optimized for this range, ensuring smooth operation and reliable loop recording. Using a card within this specification also reduces the risk of performance hiccups, especially during high-bitrate video capture.

Why Capacity Isn’t the Only Factor

While size matters, it’s not the only thing to consider. The Jennov Mini Bullet Camera records in high definition—typically 1080p or even 2K resolution—depending on the model. Higher resolution means larger file sizes, which fill up your SD card faster. Additionally, features like motion detection, night vision, and audio recording can increase data usage.

For example, a 32GB card might store 24–48 hours of continuous 1080p footage, while a 128GB card could hold up to a week or more. But if you’re using motion-activated recording, your storage could last significantly longer since the camera only records when activity is detected. Understanding your usage pattern is key to choosing the right size.

Loop Recording: How It Works

One of the standout features of the Jennov Mini Bullet Camera is its loop recording capability. When the SD card reaches full capacity, the camera automatically deletes the oldest files and continues recording new footage. This ensures uninterrupted surveillance without requiring you to manually delete videos or swap cards.

However, loop recording only works efficiently if your SD card is fast enough to handle continuous write operations. A slow or low-endurance card might struggle, leading to dropped frames or failed recordings. That’s why pairing the right size with the right speed class is critical.

Choosing the Right SD Card Size: A Practical Guide

Now that you know the basics, let’s dive into the practical side: how to choose the ideal SD card size for your specific needs. The “best” size depends on several factors, including how often you check footage, whether you use motion detection, and how long you want to retain recordings.

32GB: The Budget-Friendly Option

A 32GB microSD card is a solid starting point for casual users or those with limited surveillance needs. It’s affordable, widely available, and sufficient for basic monitoring. For example, if you’re using the camera to watch over a front door or small room with motion detection enabled, a 32GB card could last 3–5 days before looping.

However, if you’re recording continuously in high resolution, 32GB might only give you 1–2 days of footage. This could be problematic if you’re away for a weekend and miss a critical event. Still, for short-term monitoring or as a temporary solution, 32GB is a viable choice—especially if you plan to review footage daily.

64GB: The Sweet Spot for Most Users

For most homeowners and small business owners, a 64GB SD card strikes the perfect balance between cost and capacity. It offers enough storage for 3–7 days of continuous 1080p recording, or even longer with motion detection. This gives you a reasonable window to review footage without constant card swaps.

Let’s say you’re monitoring your backyard at night. With motion detection, the camera only records when someone walks by. A 64GB card could store several weeks of clips, depending on activity levels. Plus, 64GB cards are now very affordable, often costing less than $15–$20 for a reliable model.

128GB: Maximum Storage for Peace of Mind

If you want maximum storage and minimal maintenance, go for a 128GB card. This is the largest size officially supported by the Jennov Mini Bullet Camera, and it’s ideal for 24/7 recording, high-resolution video, or extended absences.

With 128GB, you could store up to 7–10 days of continuous 1080p footage, or even longer with smart recording settings. This is especially useful if you travel frequently or want to keep a longer archive of events. For example, a 128GB card might capture an entire week of driveway activity, giving you a full timeline to review if something goes missing.

Just remember: larger cards cost more, and you’ll need to ensure your camera’s firmware is up to date to support 128GB formatting. Always format the card in the camera itself—not on a computer—to avoid compatibility issues.

Real-World Example: Choosing Based on Use Case

Let’s look at a few scenarios to help you decide:

• Home Entryway Monitoring: You want to see who comes and goes. Use motion detection with a 64GB card. This gives you 5–7 days of clips, enough to catch package thieves or unexpected visitors.
• Backyard Security: You’re concerned about intruders or wildlife. A 128GB card with continuous recording ensures you don’t miss anything, even if you’re away for a week.
• Pet Monitoring: You’re checking on your dog while at work. A 32GB card with motion detection is plenty—recording only when your pet moves around.
• Business Surveillance: You need reliable, long-term footage for liability or security. Go with 128GB and regular backups to ensure nothing is lost.

SD Card Speed and Performance: Why It Matters

You might think any SD card will do, but speed and performance are just as important as size—especially for a camera that records high-definition video 24/7. A slow card can cause dropped frames, corrupted files, or even complete recording failure.

Understanding Speed Classes

SD cards come with speed ratings that indicate how fast they can write data. For the Jennov Mini Bullet Camera, you’ll want at least a Class 10 card, but ideally one with UHS Speed Class 3 (U3) or Video Speed Class 30 (V30). These ratings ensure the card can handle high-bitrate video without lag.

Here’s a quick breakdown:

• Class 10: Minimum 10 MB/s write speed. Suitable for basic 1080p recording.
• U3 (UHS Speed Class 3): Minimum 30 MB/s write speed. Ideal for 1080p and 2K video.
• V30 (Video Speed Class 30): Designed specifically for video recording, guarantees 30 MB/s sustained write speed.

Using a U3 or V30 card reduces the risk of frame drops during motion-heavy scenes, like someone running past the camera. It also helps with smooth playback and faster file transfers when you remove the card to review footage on a computer.

Endurance and Reliability for Surveillance

Surveillance cameras write data constantly, which can wear out standard SD cards quickly. That’s why you should look for cards labeled as “high endurance” or “surveillance-grade.” These are built to handle continuous write cycles and last longer under 24/7 use.

Brands like SanDisk (High Endurance), Samsung (PRO Endurance), and Kingston (Industrial) offer cards specifically designed for security cameras. While they cost a bit more, they’re worth the investment for reliability. A standard card might fail after a few months of constant use, but an endurance card can last years.

Real-World Tip: Avoid Counterfeit Cards

Be cautious when buying SD cards online. Fake or counterfeit cards are common, especially on marketplaces like Amazon or eBay. They may appear to have high capacity but actually store far less—leading to sudden failures or lost footage.

Stick to reputable retailers and well-known brands. Check reviews, look for official packaging, and verify the card’s authenticity using tools like H2testw (for Windows) or F3 (for Mac). A genuine 128GB card should pass these tests without errors.

Installing and Formatting Your SD Card

Once you’ve chosen the right SD card, the next step is installing and formatting it properly. This ensures compatibility and optimal performance with your Jennov Mini Bullet Camera.

Step-by-Step Installation

Installing the SD card is simple:

1. Power off the camera to avoid data corruption.
2. Locate the microSD card slot—usually on the side or bottom of the camera.
3. Gently insert the card with the gold contacts facing down and the label facing up.
4. Push until it clicks into place.
5. Power the camera back on.

The camera should detect the card automatically. If not, check that the card is fully inserted and compatible.

Formatting for Best Results

Always format the SD card in the camera—not on a computer. This ensures the file system (usually FAT32 or exFAT) is optimized for the camera’s firmware. To format:

1. Access the camera’s settings menu via the app or web interface.
2. Navigate to “Storage” or “SD Card Settings.”
3. Select “Format SD Card” and confirm.

Formatting erases all data, so back up any important footage first. It also helps prevent errors and improves performance over time.

Maintenance Tips

To keep your SD card in top shape:

• Format the card monthly to clear fragmented data.
• Avoid removing the card while the camera is recording.
• Store backups of critical footage on a computer or cloud service.
• Replace the card every 1–2 years, even if it seems fine—wear and tear is inevitable.
