Navigate to the Watchlist screen to upload images of individuals. Assign a name and specify whether they belong on the blacklist or whitelist.
Use the Test screen to verify recognition by uploading an image and checking detection accuracy against your configured list.
In Settings, configure Telegram by entering your bot token (available from @BotFather).
Specify the Telegram destination for alerts: either a public channel (e.g. @myChannelName) or a private chat ID (e.g. 11282822932).
The app functions without Telegram, but you won’t receive real-time alerts unless configured.
Note: Make sure your bot is in your channel otherwise alerts will not work.
Once your Watchlist and Telegram settings are configured, go to the Surveillance screen and press the record button to start monitoring.
