iBkickinit 0 Posted March 25, 2007 I am in the process of installing a 10 camera system at my house, using a geovision 16-channel card. My house is situated on the corner of a t-intersection, but the front of the house is set back 30-50 feet from the street, so the wide angle cams can't make out much detail on vehicles going by. I would like to find 1 or 2 dedicated cameras to position just to get closeups of cars going by. Is it best just to get a high quality camera with a good tight lens to focus on the street? I was curious if there was a suitable way to integrate a Megapixel caera, and set a motion zone in geovision that would trigger an output and tell the camera when to snap a photo... Any suggestions are welcome... Share this post Link to post Share on other sites
phred 0 Posted March 26, 2007 A 5-50mm varifocal lens will get you number plates at that distance and allow plenty of room for maneuver. The problem comes when the light goes low and car headlights come on. Most cameras will tend to close down and everything but the headlights will then appear black. Better quality cameras with Wide Dynamic Range will give better results but best results are obtained with specialist LPR cameras built for the job. I suggest you google 'License Plate Recognition Camera' to get a better understanding of what is involved. Rory is better equiped than I to answer your Geo question.
