Applies to: All the cameras which support SD card.
If you want to save SD card storage, there are three aspects you can or consider.
1. Reduce the resolution and Bitrate of the camera under the Record Encode page.
2. Set the motion schedule to reduce the motion recording.
For example, you may exclude the period when you are at home or the period that you think it's unnecessary to detect.
3. Set the motion areas. ( only used for the non-PIR motion cameras.)
You can exclude some areas which you think it's unnecessary to detect.
