How Long Do Security Cameras Store Footage?

The length of time that security cameras retain footage largely depends on a variety of factors, including the type of storage system, the settings on the camera, and the overall storage capacity.

1. Typical Retention Time:

For most modern security cameras, video footage is stored for a period of anywhere from a few days to a few months. However, the retention time can be altered based on the camera system’s settings and the storage options available. Generally, the more expensive systems offer longer storage durations, and users can adjust settings to keep footage for extended periods if needed.

2. Cloud vs. Local Storage:

Cloud Storage: Many newer security systems use cloud storage, where footage is uploaded to an online server. Cloud storage typically retains footage for 7–30 days, although this can vary depending on the provider. Cloud systems often offer flexibility in that you can extend storage time by purchasing additional space. Cloud systems also allow for remote access to footage, which is useful if you’re on the go.
Local Storage: Traditional security systems often store footage locally on devices like DVRs or NVRs (Network Video Recorders). Local storage systems can provide longer retention periods, sometimes extending for several months, depending on the system’s storage capacity. However, the downside is that local storage is more prone to theft or damage in case of a burglary, so it may not always be the most secure option.

Storage Duration Control:

Some advanced systems allow users to manually configure the retention duration. For example, you might want footage from the past 30 days to be kept, after which it is automatically overwritten. This flexibility makes it easier for businesses and homeowners to manage their storage needs effectively.
