Concrete case

== At my office == i have 3 cameras and 1 NVR : * DS-2CD2746G2-IZS verry good IA, never false positive * DS-2DE4225IW-DE poor IA, lot of false positive * DS-7608NXI-I2 / S midle IA, some false positive * DS-2CD2086G2-I verry good IA, never false positive

The NVR manage only DS-2DE4225IW-DE to reduce false positive.

A Glinet router with Openvpn client and a computer runing Linux mageia 8. On the computer i have crontabs for the folowing : HikNetExtractor evry 1 minute, because the python script manage already running. It extract recorded video from devices to a USB Disk. A bash script run every minutes, with handle of already running to Rsync USB Disk to home.

== At home == My Net Box provide a Openvpn server. A Rapberry PI400 with a USB Disk and running a Rsynk server.

Every mornings, i use QtVsPlayer to watch videos, in the future, i hope, i will manage a view mode with only motion/VCA frames and gain more time. The Classicnotify.sh script, watch my network share for new videos, display Gnome notification, clic on it open video with QtVsPlayer or add it to the playlist.
