Using Snapshots
If for any reason standard portrait photos cannot be taken, you can increase the recognition
performance by using snapshots taken from the surveillance site. Possible scenarios may
include:
Nighttime Recognition:
where the installation site may not be subjected to IR LED
enrollment conveniently.
Special Entities:
who are unwelcomed or who refuse to comply with the standard
enrollment process.
Frequently Misrecognized Entities:
whose personal photos were not taken properly,
which leads to deficient recognition results.
