Calculate Your Security Camera Bandwidth Needs

Use the calculator below to estimate how much network bandwidth your NVR and cameras may require for recording and remote viewing.

What Does Bandwidth Determine in a Security Camera System?

Bandwidth determines how much video data your network can handle at one time. Every IP security camera sends a video stream to the recorder, and the more cameras you install, the more total bandwidth your system requires.

Bandwidth affects how many cameras your NVR can support, how smoothly your system performs in live view, and how well your cameras stream for remote viewing on phones and computers.

How Camera Bandwidth Is Calculated

Camera bandwidth is typically measured in megabits per second, or Mbps. The amount used depends on resolution, frame rate, compression type, and scene activity.

In general, 1080p cameras use less bandwidth than 4MP or 4K cameras, and H.265 compression is typically more efficient than H.264.

Bandwidth and Remote Viewing

Remote viewing also uses bandwidth. If you view multiple cameras at once or stream full-quality video, your bandwidth needs increase.

Many systems use a lower-bandwidth substream for mobile viewing, which can reduce demand while still providing smooth access to live video.

Bandwidth Calculator FAQs

What does bandwidth determine in a security camera system?

Bandwidth determines how much video data your network and recorder can handle at one time. It affects camera capacity, recorder performance, live view, and remote viewing quality.

Why does a 4K camera use more bandwidth?

A 4K camera sends more image data than a lower-resolution camera, so it usually requires more bandwidth and more storage space.

Does H.265 reduce bandwidth usage?

In most cases, yes. H.265 is generally more efficient than H.264 and can reduce bandwidth demands while maintaining strong image quality.
