text: speeding vehicles, remote sensors and cleaning up the neighborhood in memory of a run down pet.? i want to calculate the speed of vehicles passing my house on the street. i will need to activate a camcorder as the vehicles pass with a remote sensor device.  the camera will need to shut off in a few seconds and be able to record the next vehicle.  what remote device is the most practical?  the distance the vehicle will need to  travel and the distance from camera and remote sensor is also relative.  any ideas? crackerboy is just mean isnt he... you would need to set up the camera with something to gauge the distance on the other side of the road. for setups like this, i recomend watching the mythbusters here and there, they show how to do it on many episodes. i think they make that kind of camera, with the remote cencor,(i know my spelling sucks)for stuff like hunting. they use them for watching game and stuff, they even tell you what time they are recording. i have some sites with the information below. for more sites just search game trail cameras, or camcorders. good luck, and i am sorry to hear of your poor pet.
