How much Data does a Security Camera use Per Day?

The amount of data a security camera uses per day can vary widely depending on several factors, including the camera’s resolution, frame rate, compression settings, and whether it’s continuously recording or triggered by motion events. Let’s delve into these factors to better understand how much data a security camera might use on a daily basis.

Resolution and Quality:

Resolution refers to the number of pixels in an image. Security cameras come in various resolutions, such as 720p (HD), 1080p (Full HD), 2K, and 4K. Higher resolutions produce more detailed images but also require more data to transmit and store. Cameras with higher resolutions consume more data per frame, leading to larger data usage overall.

Frame Rate:

Frame rate is the number of individual frames (images) captured by the camera per second. Common frame rates include 24, 30, and 60 frames per second (fps). Higher frame rates provide smoother video footage but also increase data consumption. If a camera is set to record at 30 fps, it will generate more data than if it were set to 15 fps.

Compression Settings:

Modern security cameras use video compression algorithms to reduce the size of video files without significantly compromising image quality. Common compression methods include H.264, H.265 (HEVC), and more. These methods remove redundant data and compress the video stream, resulting in smaller file sizes. Cameras with more advanced compression technologies will use less data per unit of time compared to older compression methods.

Recording Mode:

Security cameras can be set to record continuously or only when motion is detected. Continuous recording uses more data since it’s capturing footage non-stop. On the other hand, motion-activated recording saves data by only recording when there’s activity, potentially reducing the overall data usage.


Bitrate is a critical factor in determining data usage. It’s the amount of data transmitted per second, usually measured in kilobits per second (kbps) or megabits per second (Mbps). A higher bitrate results in better image quality but consumes more data. Cameras with adjustable bitrate settings allow users to balance image quality and data usage based on their preferences.

Calculation Example:

To provide a rough estimate, let’s consider a security camera with the following parameters:

  • Resolution: 1080p (1920×1080 pixels)
  • Frame rate: 15 fps
  • Compression: H.264
  • Bitrate: 2000 kbps

Using these settings, we can calculate the average data usage per day:

Bitrate per second = 2000 kbps = 2000 / 8 KBps ≈ 250 KBps

Data usage per minute = 250 KBps × 60 seconds ≈ 15,000 KB ≈ 14.65 MB

Data usage per hour = 14.65 MB × 60 minutes ≈ 879 MB

Data usage per day = 879 MB × 24 hours ≈ 21.1 GB

Keep in mind that this is just an example calculation. Actual data usage can vary based on real-world conditions, camera settings, and environmental factors. Additionally, different camera models might employ different compression methods, leading to variations in data consumption.

It’s important to note that many modern security cameras offer cloud storage options, where the captured footage is uploaded to remote servers. These services often come with subscription plans that offer varying amounts of storage space and data retention periods. Users should carefully consider their data needs and choose a plan that aligns with their usage patterns and requirements.

In conclusion, the amount of data a security camera uses per day depends on factors such as resolution, frame rate, compression settings, recording mode, and bitrate. Users have the flexibility to adjust these settings to balance data usage and image quality according to their preferences. When choosing a security camera or setting it up, it’s crucial to consider these factors to ensure efficient data usage and proper storage management.
