1. Timeline is 1 week after all materials bought. I buy all materials of course for you. Send them to you.
3. Want a trigger that is right next to DSLR camera. Not a trigger that is wirelessly tethered to camera that is some distance away. I'd like trigger and camera very close to each other.
4. Trigger just for presence of car. Not distance or speed.
2. Not sure if mechanical vs electronic trigger...how is a DSLR Nikon camera triggered?
