Investigation module configuration
SmatFace Station v5_1.12 introduced a new investigation module, where user can upload video files for investigation. This functionality requires configuration changes for proper connection between the Min.IO and the SmartFace Station.
It is necessary to set these parameters in the configuration file in SmartFace Station:
S3_ENDPOINT - machine host name or IP where MIN.IO/S3 is installed (default - pseudo IP address of the local computer)
S3_ACCESS_KEY - login
S3_SECRET_KEY - password
S3_BUCKET - a container for objects stored in S3.
Default values after SmartFace Station installation are:
This will not work, when you run SmartFace Station on a client computer. The SmartFace Station will search for MIN.IO database on the client machine, not on the server.
Example with host name:
If the client computer is in the network, where
sfit-sface-3w server is reachable, the user will be able to upload video files.
SmartFace Station configuration file location
The default location for
.env file is:
C:\Program Files (x86)\SmartFace Station\
For LINUX deployment:
The default location for
.env.sfstation files is:
