## CPU initial AI,this will display the live camera windows on the computer screen, can be useful with a laptop
## source ../y8ovv/bin/activate
#python3 AI2.py -nsz -d -y8ovv  2>/dev/null >> ../detect/`/bin/date +%F`_AI.log &

## this will not display anything, minor speedup, best if AI host is "headless"
#python3 AI2.py -nsz -y8ovv  2>/dev/null >> ../detect/`/bin/date +%F`_AI.log &

## TPU initial AI, openvion yolo8 detection, use -y8v for CUDA yolo8, -nsz doesn't save zoomed detections
#python3 AI2.py -tpu -nsz -y8ovv  2>/dev/null >> ../detect/`/bin/date +%F`_AI.log &

## example to tile 4 cameras on a 1920x1080 screen
## algorithym I use:
# define grid, say 2 rows by 3 columns
# fudgeFactor = 8 
# -iw = int(-dw / columns) - fudge factor
# -ih = int(-iw * 9 / 16)
#python3 AI2.py -nsz -d -y8ovv  -dw 1920 -dh 1080 -iw 944 -ih 531 2>/dev/null >> ../detect/`/bin/date +%F`_AI.log &
