What size memory card do household cameras usually use?

This depends on how long the user wants to keep the video backup and the compatibility of the device. Generally, it is at least 64G, which can save videos for about a week. If you want to save more, you can buy a bigger one.

However, some surveillance cameras provide cloud storage. If you don't buy cloud storage, try to choose a large-capacity memory card so that users don't have to worry about when the data in the memory card will be full every day. If you think the data stored in the surveillance camera or wireless network camera is very important, you can back it up once every six days. If you are too lazy to back it up, you can let it automatically overwrite it.
