Are you wondering how much data do security cameras use? Yes, as a homeowner, It’s an important thing to consider, especially if you’re on a limited internet data plan.
When we installed cameras at our home, we went way over our monthly data cap which caused all sorts of connectivity issues.
It was a frustrating experience until I learned more about optimizing security camera data usage. After adjusting some settings, we were able to cut our usage in half.
In this post, I’ll explain what factors impact security camera bandwidth so you can avoid data overages.
With the right setup, you can enjoy security camera monitoring without devouring your home’s internet data.
Let’s dive in!
Key Factors To Determine How Much Data Do Security Cameras Use
There are a few key factors that determine how much data a security camera system will use, including:
- Video resolution and quality – Higher resolution and quality levels will use more data. 720p and 1080p resolution will use more data than lower 480p or 360p resolutions.
- Frames per second (FPS) – More FPS means more frequent video updates, which uses more data. 15-20 FPS is common.
- Motion detection – Constant video feeds use more data than motion activated recording.
- Onboard storage vs cloud storage – Cloud systems require constant data uploads, using more bandwidth. Local storage records directly to an NVR or SD card.
Generally, higher quality video settings will result in more data usage. But you can tweak these settings to help manage your camera bandwidth needs.
Wired vs Wireless Security Camera Data Usage
One of the big factors in security camera data usage is whether the cameras are wired or wireless.
Let’s look at some of the key differences:
Wired PoE Security Cameras
Wired cameras like PoE IP cameras connect directly to your home or business ethernet network via cable.
This provides a high-bandwidth dedicated connection for transferring security video.
Some advantages of wired cameras:
- Don’t use your regular wireless network bandwidth
- Can support higher resolution video
- Often have direct local storage to an NVR
The main downside is that wired cameras can be trickier to install since you need to run cabling.
Overall though, wired PoE cameras tend to use less data since they have their own network pipeline.
Wireless WiFi Security Cameras
Wireless cameras connect to your home WiFi network for transmitting security footage. This allows for easier flexible installation without running cables.
However, there are some downsides:
- Share wireless network bandwidth with other devices
- Limited by your internet plan data cap
- Video quality may be lower to conserve bandwidth
In general, wireless cameras have higher bandwidth usage since they compete for your overall WiFi data capacity.
You may need to adjust video settings to accommodate limited wireless data transfer.
Other Options like LTE Cameras
A third option is using cellular LTE security cameras that have their own data plan. This removes them from your home WiFi network and wired connections.
Advantages of LTE cameras:
- Don’t count against home internet data allowance
- Flexible installation anywhere with cellular signal
- Real-time monitoring and notifications
Downsides tend to be higher costs for cellular data plans and potential signal issues.
But LTE cameras are a good alternative to reduce wireless home network data usage.
Cloud Storage vs Local Storage for Security Footage
Another factor in security camera data usage is how and where video recordings are stored:
Cloud Storage
Many newer security camera systems upload all footage to the cloud for storage and remote viewing.
This provides convenience but uses a lot of bandwidth for constant big video uploads.
Local Storage with an NVR
Network video recorders (NVRs) allow local storage of security footage via wired connections to cameras.
This approach uses very little internet data. But you lose remote access and have to manage physical storage.
Hybrid Cloud + Local Storage
Some systems take a hybrid approach, storing continuous 24/7 recording locally while sending motion event clips to the cloud.
This gives you remote access to key events without maxing out your internet data.
Choosing the right storage setup can help minimize high video upload bandwidth usage.
For maximum data efficiency, local NVR storage is best but limits remote access and convenience.
Estimating Data Usage Based on Camera Settings
So how much data will your security cameras actually use? It really depends on the resolution, frame rate, compression and other settings.
Here are some guidelines on data usage:
By Video Resolution
- 360p cameras: ~0.5GB per camera per day
- 720p cameras: ~1.5GB per camera per day
- 1080p cameras: ~2.5GB per camera per day
Higher 4K resolution cameras can use 5GB or more per day depending on settings and motion amounts.
By Frames Per Second (FPS)
- 5FPS: ~0.9GB per camera per day
- 10FPS: ~1.5GB per camera per day
- 15FPS: ~2GB per camera per day
- 30FPS: ~3.5GB per camera per day
Higher frame rates capture more motion but use significantly more data.
By Features Like Motion Detection
- Continuous recording: ~3GB per camera per day
- Motion-activated: ~1GB per camera per day
Monitoring data usage for a week with normal activity can give you a good idea of average needs.
Here’s an overview of estimated data usage based on video settings:
| Resolution | Frames Per Second | Data Used Per Camera |
|---|---|---|
| 480p | 10FPS | ~0.6GB/day |
| 720p | 15FPS | ~1.5GB/day |
| 1080p | 20FPS | ~2.5GB/day |
| 4K | 30FPS | ~4-6GB/day |
Of course, actual usage will depend on specific camera models and features. But this table gives you a general idea for different configurations.
Tips to Reduce Security Camera Data Usage
If you want to cut down on your security camera system’s data usage, here are some tips:
- Lower video resolution – 720p or 480p uses less data than full 1080p or 4K.
- Reduce frames per second – Cutting FPS from 30 to 15 can significantly lower data usage.
- Use motion detection – Record only when motion events occur instead of 24/7.
- Enable H.265 compression – H.265 compression reduces video file sizes by ~50% over H.264.
- Use local storage – Store footage on an NVR or SD card rather than uploading to the cloud.
- Limit video length – Don’t record 24/7, set a max timeframe to conserve data.
- Set data limits – Configure camera system data allowances or restrictions.
- Add LTE cameras – Cellular cameras use their own data plan to reduce home WiFi usage.
Getting the right balance of video quality, features, and settings can help keep your security camera data usage reasonable.
