What Internet Speed Do I Need for Security Cameras? Onsite vs Offsite Storage Explained

Have you ever set up a security camera only to find the footage looks more like a slideshow than a video? Or perhaps you've tried accessing your cameras remotely and spent more time watching that loading icon spin than actual surveillance footage? If so, you might be dealing with an internet speed issue.

In this guide, I'll walk you through exactly what internet speeds you need for your security camera system, whether you're storing footage onsite or in the cloud. Let's get your security system running smoothly!

Understanding the Basics: How Internet Speed Affects Your Security Cameras

Before diving into specific numbers, it's important to understand that security cameras require two types of internet speed:

• Download speed: How quickly data travels from the internet to your devices

• Upload speed: How quickly data travels from your devices to the internet

When it comes to security cameras, upload speed is typically the more important factor, especially if you're storing footage in the cloud or accessing cameras remotely.

Recommended Internet Speeds for Security Cameras

The internet speed you'll need depends on several factors:

Camera Resolution

• Standard Definition (SD): 1-2 Mbps per camera

• High Definition (1080p): 2-4 Mbps per camera

• 4K Ultra HD: 5-10+ Mbps per camera

Number of Cameras

Simply multiply the required speed per camera by the number of cameras in your system. For example, if you have four 1080p cameras, you might need 8-16 Mbps of upload bandwidth.

Frame Rate and Compression

Higher frame rates (more frames per second) require more bandwidth. Similarly, the compression technology used by your cameras affects bandwidth needs. Modern H.265 compression requires significantly less bandwidth than older H.264 compression.

Onsite vs Offsite Storage: How Your Storage Choice Affects Internet Speed Requirements

Onsite Storage (Local Recording)

If you're storing footage on local devices like a Network Video Recorder (NVR) or DVR, your internet speed requirements are much lower. Here's why:

• Your cameras record directly to the local storage device over your home or business network

• Internet speed mainly matters for remote viewing of footage

• You'll only need moderate download speeds (10+ Mbps) for watching footage remotely

• Upload speeds become relevant only when accessing cameras while away from home or business

Bottom line for onsite storage: Your local network speed is more important than your internet connection. A decent home or business Wi-Fi network or wired connection will handle multiple cameras without issue.

Offsite Storage (Cloud Recording)

Cloud storage is where internet speed becomes crucial. When your footage is stored in the cloud:

• Video must be continuously uploaded from your cameras

• Upload speed directly affects video quality and reliability

• Insufficient upload speed can cause choppy video, gaps in recording, or connection failures

Recommended speeds for cloud storage:

• Minimum: 5 Mbps upload for a small system (1-2 cameras)

• Recommended: 10+ Mbps for multiple cameras or 4K resolution

• Ideal: 20+ Mbps for larger systems with 4+ high-resolution cameras

Real-World Considerations and Tips

Test Your Actual Internet Speed

Don't just rely on what your internet provider advertises. Use a service like Speedtest.net to check your actual upload and download speeds.

Consider a Hybrid Approach

Many security experts recommend a hybrid approach:

• Store footage locally for continuous, reliable recording

• Use cloud storage as a backup for important clips or when motion is detected

• This balances bandwidth usage while maintaining the benefits of both storage methods

Adjust Camera Settings to Optimize Bandwidth

If your internet speed is limited, consider:

• Reducing resolution (e.g., from 4K to 1080p)

• Lowering frame rate (from 30fps to 15fps)

• Enabling more aggressive compression

• Using motion detection to only record/upload when necessary

Consider Dedicated Business Internet for Large Systems

For systems with many cameras, especially in business settings, consider:

• Business-grade internet connections with guaranteed upload speeds

• Symmetric connections where upload speed equals download speed

• Service level agreements (SLAs) that guarantee uptime

Final Thoughts: Making the Right Choice for Your Needs

When deciding between onsite and offsite storage, consider these factors:

Onsite Storage Pros:

• Lower internet speed requirements

• No monthly cloud storage fees

• Complete control over your data

Onsite Storage Cons:

• Vulnerable to theft or damage

• Requires hardware maintenance

• Limited remote access features

Offsite/Cloud Storage Pros:

• Accessible from anywhere

• Protected from physical damage or theft

• Often includes advanced features like AI detection

Offsite/Cloud Storage Cons:

• Requires robust internet connection

• Ongoing subscription costs

• Potential privacy concerns

Whatever option you choose, ensuring you have adequate internet speed will keep your security system running smoothly and your property properly protected. When in doubt, it's always better to have more bandwidth than you think you'll need security is one area where you don't want to cut corners!
