From the DVR, PC/Mac or Android/iOS software you may search back through any recorded footage.
Playback is fully supported in the apps and PC/Mac software. You can search by date and time for any number of cameras footage, and play it back.
On some systems 'Smart Search' is also available, which allows you to mark an area, and the system will automatically fetch all footage where it detects motion in that area. This is incredibly useful when no narrow time frame can be determined.
Tutorials for playback will be added soon.
