Iracing comes with a std camera pack so you can watch replays or races live.
If like me you want better camera’s or real live camera’s then Track Cams for Gourmets is for you.
– Accuracy and detail – cameras on ‘realistic’ positions (behind fence, on poles, etc), real life camera positions. Trying to create variing camera angles with placement and carefully planned and updated camera transitions. Pursue realism just what iRacing is aiming for.
– Static TV, DynamicTV –
– Cinematic angles with depth of field enabled – Aiming for best visuals possible. Utilizing depth of field effects to enhance feeling of distance.
– Continous updates – until i’m here you can expect updates because i’m never satisfied 
In general I use 5-6 camera groups (there can be some exceptions):
Group1 (TV1) is TV style or uses real life camera angle replica
Group2 (TV2) probably the most cinematic, getting the most out of depth of field and focusing to deliver good images of the car (to give some feeling of speed, to better show paints, duels close, etc)
Group 3 (TV3) set is wider zoom showing longer sections of track (useful at starts or to follow multi car actions)
Group 4 (StaticTV) – uses static aim type cameras
Group 5 (DynamicTV) – simulates low altitude chopper (check the second video)
Group 6 (Random TV) – contains best of group1-5 angles plus a few more and including onboards to give you full TV style experience
PitLane – updated pitlane cameras starting from 03/16 release
Scenic – updated scenics with more cinematics from 03/16 release
