What size SD card is recommended for a security camera?

If you’re looking to buy a security camera, one of the first questions you’ll ask is “What size SD card is recommended?” The answer, unfortunately, is not as straightforward as you might hope. It depends on a number of factors, including the resolution of your camera, the frame rate, and the bitrate.

In general, the higher the resolution and frame rate of your camera, the larger the SD card you’ll need. The bitrate is also a factor; if your camera records at a high bitrate, you’ll need a larger SD card to store the same amount of footage.

To give you an idea of what size SD card you might need for your security camera, we’ve put together a quick guide. Keep in mind that these are only estimates; your actual needs may vary depending on your specific setup.

Conclusion

When it comes to picking the right size SD card for your security camera, there is no one-size-fits-all answer. The best way to figure out what size SD card is right for your needs is to consider how much footage you plan on storing and how often you’ll be downloading or backing up that footage. If you only need to store a small amount of footage and you don’t mind downloading or backing up that footage regularly, then a smaller SD card will suffice. However, if you plan on storing a large amount of footage or you won’t be able to download or back up that footage as often as you’d like, then a larger SD card is recommended.
