The amount of storage you need on your mobile device to use a hidden camera with a mobile app depends on the resolution and frame rate of the video footage. Higher resolution and frame rates result in larger video files and therefore require more storage space. For example, recording at 1080p resolution at 30 frames per second can use up to 350 MB of storage per minute of video. Take a look at our Data Storage Calculator to find out how much storage your camera might need.
It is recommended to have at least 2-3 GB of free storage space on your mobile device to use a hidden camera with a mobile app, but this can vary depending on your usage habits and the frequency of recordings. It’s important to regularly transfer or delete footage to free up storage space and prevent your mobile device from running out of space, or use loop recording to automate this task for you. Some hidden camera mobile apps also offer cloud storage options as an alternative to local storage on your mobile device. Many hidden spy cameras will also record footage on a local SD card, but also give you the option to view it remotely through a mobile app.
