10-15 fps is probably OK outdoors on a camera facing the street. You don’t have to run all cameras at the same framerate, BTW.
It actually depends more on how far the camera is from the road. Go further, you can get away with a lower framerate since a moving object is in the image for a longer time.[/quote]
Absolutely, there are a lot of variables and many ways to go.
The solution you propose will work for many people, especially those who aren’t interested in tracking something that moves faster than 10 MPH.
But if you want to get a good shot at someone who is running or a car that is fleeing quickly, you had better give consideration to higher quality cameras that can do faster frame rates.
As I said before, if you just wanna see a blob move through a room or down a sidewalk, go get a Costco solution. If you want more, you should either evaluate a demo system first or plan on buying a lil more than you think you need – just so you don’t end up with a system that won’t do what you want it to do (which may change over time).
And next time you grab a snap from one of those systems you install…have someone run across the field of view and see how good a frame snap you can get of that person. I think you’ll see my point.
