Wanna know the detailed information about IP camera bandwidth calculation, like: What are the 720p,1080p or 4MP IP camera bandwidth requirements? How much data do security cameras use? Here you’ll learn the bandwidth calculation for IP cameras as well as the insider tips to reduce bandwidth consumption.
CCTV Bandwidth Calculator: Formula & Example
Besides using the various IP camera bitrate calculators online, you can also calculate the Internet speed needed for security cameras on your own.
Below we’ll introduce an easy IP camera bandwidth calculation formula and the 4 variables affecting your IP camera bandwidth usage (calculated in ideal environments).
Top 4 Elements that Affect IP Security Camera Bandwidth/Internet Speed
- Resolution. Higher resolution will require more IP camera Internet bandwidth.
- FPS (Frame Rate per Second). The higher the FPS is, the more IP camera bandwidth usage is required.
- Video compression codec. It determines how the video is packaged and compressed before being sent over the Internet. There are 2 popular video compression format types: H.264 and MJPEG. H.264 HD IP cameras, with better compression, lower the security camera Internet speed requirements for transmitting video streaming.
- The quantity of your IP security cameras. The more IP cameras you are using, the higher Internet speed is needed for your security cameras.
The above 4 variables, determining the IP camera bitrate, interact and affect each other.

Follow the below IP camera bandwidth calculation formula, and you can get the answer for IP camera bandwidth problems like “How much bandwidth do I need for security cameras? How much data does a security camera use?”
IP Camera Bandwidth Calculation Formula:
Follow the below IP camera bandwidth calculation formula, and you can get the answer for IP camera bandwidth problems like “How much bandwidth do I need for security cameras? How much data does a WiFi security camera use?”
Bandwidth (Mbps) = Bitrate (Main) * N + Bitrate (sub) *M
*N & M represents the number of IP cameras for main stream and sub-stream.
In terms of the bitrate in this formula, you can check them in the specifications of your IP cameras or ask the security camera company staff directly.
Example: If you have one IP camera with the main stream of 6144 kbps and another with the sub stream of 1024 kbps, the required IP camera bandwidth would be
Required Bandwidth = 1 * 6144 kbps + 1 * 1024 kbps =7168 kbps = 7.168 Mbps
Since the bandwidth calculation of IP cameras would be too overwhelming, you can view the below IP camera bandwidth chart, including 2MP camera data consumption and 4K security camera bandwidth requirements, to see the overall Internet speed needed by your security IP cameras.
How much data does CCTV streaming use? Does an IP camera use bandwidth all the time? Hopefully you can get the answers you want in the information provided above.
Besides the internal factors that affect the IP camera bandwidth, the external factors, such as different installation places, can also affect the IP camera data usage calculation.

Security Camera Bandwidth Calculator for More Accurate Result of CCTV IP Camera Data Usage
The above bandwidth calculation formula for IP cameras is suitable for ideal environments.
However, the IP camera bandwidth usage varies in different scenarios. Thus it is impossible for the IP camera bandwidth calculators online to show you the most accurate calculation result.
Other external factors, such as the bright or dark environments, can also affect HD IP camera bandwidth consumption or Internet usage.
Special applications, like facial recognition or license plate recognition, will eat up more camera bitrate, since these applications require higher resolution and frame rate recording.
If you want more accurate IP camera bandwidth calculation result, you need to do some tests by yourself:
Test your security cameras and record the IP camera bandwidth requirements in different scenes/places.
You can place your IP cameras in different places to see how much your IP cameras will eat up the Internet data with the CCTV bandwidth calculator software online.
Below are the scenes ranging from simple to complex:
- Simplest: A wall
- Simple: Empty room
- Medium: A well-lit room
- Complex: Parking lot/garage
- More complex: busy entry way
By testing in different situations, you will get more accurate results on your IP camera bandwidth usage.
According to our multiple tests, the result is that the busier places the IP cameras are installed, the higher bandwidth is needed.
If you are searching for IP camera bandwidth and storage calculators for Axis, Bosch, Dahua, Sony, Vivotek, Samsung, Pelco, Panosonic, Cisco, Honeywell, Generic, Geovision or Hikvision CCTV cameras, remember to bear the above information in mind.
With the full knowledge on IP camera bandwidth calculation above, you can certainly find the most suitable IP camera that won’t use much data.
Tips to Reduce the IP Camera Bandwidth Usage
You may also wonder the following questions: Does an IP camera use bandwidth all the time? Do WiFi cameras slow down Internet? Probably not!
The fact is that, the CCTV security cameras use data only when you access the cameras for live viewing or they send you instant alerts when motion events are detected.
Better yet, here are some effective tips you can try to reduce your IP camera bandwidth consumption.
- Choose H.264 video compression codec instead of MJPEG.
- Use the right resolution based on your needs. you can select the sub-stream type when accessing your IP cameras or recording videos.
- Lower the frames per second (FPS) to reduce the IP camera bandwidth usage.
- Set up motion detection recording.
- Reduce the number of cameras by utilizing wide-angle PTZ security cameras.
- Choose dual band WiFi security cameras and connect them to the less crowded frequency band .

FAQs
How much bandwidth does a 1080p CCTV camera use?
On average, a 1080p CCTV camera using H.264 compression at 30 frames per second (fps) can consume around 2-4 Mbps (megabits per second) for a single camera stream. The security camera data usage may increase due to higher frame rates, less compression, or more complex scenes.
How much data does a security camera use per month?
For a 1080p camera recording at 15 frames per second (fps) with moderate compression (H.264), it might use around 60-100 GB of data per month for continuous recording. If the camera is set to record only when motion is detected, for example, battery-powered security camera, the data usage will be significantly lower.
Higher resolution cameras will consume more data. For example, a 4K camera recording continuously might use 300-500 GB or more per month.
Is 30 Mbps enough for CCTV camera?
Yes, a 30 Mbps internet connection can typically support multiple CCTV cameras, but the number of supported cameras depends on factors such as camera resolution, compression, and specific features. With 1080p cameras using around 2-4 Mbps each, the network may support between 7 to 15 cameras on a 30 Mbps connection, while higher-resolution cameras like 4K might require more bandwidth and support fewer cameras.
Conclusion
Knowing the bandwidth requirements of your CCTV cameras is crucial for ensuring smooth and efficient operation of your surveillance system. By using a camera bandwidth calculator, you can accurately estimate the amount of data your cameras will consume.
