Based on a couple of week-days of traffic, I estimate that our average daily traffic is between 100 and 150 per day. That includes traffic traveling in both directions.
There is some guess-work involved because the camera is much more capable at seeing vehicles going away than it is coming toward it. I suspect that the trigger is in the IR portion of the spectrum and tail-pipes are a very crisp signal.
Maybe you need two cameras, one facing up the road and one facing down the road?
ReplyDeleteIt might also be doppler effect, with the approaching vehicles compressing the wavelength.
ReplyDeleteLOL.
DeleteThey would have to be traveling at significant fraction of the speed-of-light. Infrared-to-visible red is about a halving of the wavelength so the vehicle would have to be going roughly 330 million miles-per-hour.
The shock wave would have obliterated my house.
