2	Select the best frame for recognition	Set the checkbox	Enables/disables function of selection the best frame for recognition on the Face recognition server	Boolean type	Yes	Set — the Face recognition server selects the best image for one face from the received images and performs recognition using it Clear — the Face recognition server doesn't select the best frame for one face from the received images
The Settings group
3	Similarity level	Enter the value into the field	Sets the similarity level of a captured face and a reference image above which the face is considered recognized	%	50	From 0 to 100
4	Search for similar faces	Enter the value into the field	Sets the maximum number of matching reference images the identifiers and similarity level for which will be stored in the database for one frame with a captured face	units	5	From 1 to 20
5	Minimum quality for face recognition (0-100)	Enter the value into the field	Sets minimum quality for face recognition in percent	%	60	From 0 to 100
6	Minimum quality for adding face to DB (0-100)	Enter the value into the field	Sets minimum quality for face to be added to the database in percent	%	80	From 0 to 100
7	Create FIR in detection unit	Set the checkbox	Enables/disables function of generation biometric face parameters in the Face detection at which the corresponding Face recognition server is selected as external capture	Boolean type	Yes	Set — a vector is created in the Face detection and it is sent to the Face recognition server Clear — a vector is created on the Face recognition server
8	Select the best frame in detection unit	Set the checkbox	Enables/disables function of selection the best frame for recognition on the Face detection site	Boolean type	Yes	Set — the Face detection selects the best frame for one captured face among the received images and sends it to the Face recognition server Clear — the Face detection sends all frames for one captured face to the Face recognition server
9	Skip repeated recognitions, s	Enter the value into the field	Sets time period in seconds during which repeated recognition will be ignored by the system	seconds	2	>2
10	Use GPU	Set the checkbox	Activates the recognition on a discrete graphics card when the Tevian VA face recognition module is used	Boolean type	No	Set — the recognition will be performed on a discrete GPU Clear — the recognition will be performed on a CPU
