How Much Data Do Wireless Home Security Systems Use?


Wireless security cameras are becoming increasingly popular with homeowners and can usually provide audio and video recording of significantly higher quality than wired models. While wired security cameras tend to be more expensive and may require professional installation, the wireless devices are comparatively small and are easy to set up, even for people with limited technical knowledge or ability.

There are a few main factors to consider when planning the Internet connection speed / bandwidth requirements to implement a wireless camera security system. These include:

  • Video Recording Resolution
  • Video Compression / Codec Used
  • Number of Cameras
  • FPS (Frame Rate per Second)

Each of these factors will affect how much data the home security system will use, with higher resolution, higher frames per second and, of course, more cameras contributing to greater amounts of data transfer needs. While it’s possible to install 10 or more cameras in your home, too many video streams will bog down a wireless router and degrade the performance of the security cameras and any other service or device that’s connected to the Internet.


Another factor contributing to data use would be if your camera’s are always recording and uploading to the cloud or, as many find sufficient, will record when triggered by movement or sound. Wireless cameras that are always recording will take vast amounts of data, in many cases exceeding an ISP’s data upload limits.

For example, an always-on system that is always uploading can easily use over 60GB of data transfer (uploading) per month, so a popular and more reasonable method that can fit into most existing internet service plans is to set the camera to respond to motion, which generates an alert based on the sensitivity you set.

When you get alerts, they generate one or more still images or a link to a video clip that typically runs about 30 seconds long. There are several ways to view and/or store these images, and different devices offer different combinations of these features, but more and more, this data is going out over your internet connection for storage in the cloud.

Most digital internet service providers these days will have no trouble accommodating the data transfer from wireless security systems but it helps to know both your internet plan’s upload speed and if there is a cap, or maximum amount that you’re allowed to upload per month.


How much data does Cammy use to upload triggered events to the cloud? Cammy is designed to be easy to set-up, use and to be light on your internet connection. An event is typically recorded when motion detected is 10 seconds long. At 1.5 frames per second and uploading just under 700kb, this shouldn’t cause any noticeable degradation of your internet connection as this is roughly the same amount of data you might use when viewing a web page, a single medium to high-quality digital image, or downloading a few emails.

Few household connections will be ready to handle non-stop video recording to the cloud, but most allow more than enough data transfer to effectively support your motion-sensitive wireless home security camera system. If you’re not sure what your internet connection will handle, or how much you’re allowed to upload before being charged for extra use, contact your ISP to find out.
