thanks all guy's
I have read with great interest your recommendations all though I have not replied individually.
It is mainly to get hit and run drivers, wife has been done twice, and 2ndly for theft or burglary etc.
I think I'm going to go with a 8mp system, I may look at some DIY systems, I'm in IT myself
feel free to add anything here I will always read your inputs and I may come back if I have any questions
THANK YOU ALL !!!!
