Unable to detect cars

Hi,

I'm trying out frigate and got person detection working fine. I'd like to also detect car objects but I haven't got it to work so far. I have frigate installed as an app on my truenas server running on a intel i5-3320M.

Here is my config file, am I missing something? :

mqtt:

enabled: false

#-------------entrance camera--------------------

cameras:

entrance: #

enabled: true

ffmpeg:

inputs:

- path: rtsp://user:password@192.168.0.189/stream1 # <----- The stream you want to use for detection

roles:

- detect

- path: rtsp://user:password@192.168.0.189/stream1 # <----- The stream you want to use for recording

roles:

- record

hwaccel_args: preset-vaapi # <----- Intel hardware acceleration

detect:

enabled: true

Thanks!
