I currently have 4 cameras mounted on 4 different sides of my car. I have a linux box running fc4 and zoneminder for recording. It keeps a close check on my car when i'm not in it (like when it is parked) and the setup helps out with views while i'm driving. However, there is one thing I want to be able to accomplish with a setup like this. If there happens to be a car in my blind spot on my left or right side the cameras can see it, but if i'm not looking at my split monitor I don't see the car. Is there a way, not neccisarily with zoneminder and/or the cameras, for my car to alert me if an object or car is too close? Laugh if you'd like, but I really need a solution because i'm a severly overcautious new driver that wants his expirience to be as fool proof as possible while driving. Making some kind of sensors work for this with entirely different software would be cool also. Thanks for any help.

Whatever happened to turning your head slightly and checking manually .

I personally think relying on a machine to do this for you is a bad idea as a software crash could lead you to a car crash. Just check your blindspots for yourself.

I get where your coming from. But you see, occasionally everyone forgets to look. This would only be reassurance.
