Hi guys! So I have an accountant office, and the windows has been destroyed 2 times in a month, someone is angry after me for I don't know why, and the thing is my current system is currently trash and my technician keeps charging me for fixes that never works, so im resorting to you guys' help because I am gonna go bankrupt if that continues, so I need a security camera system that works over wifi or bluethoot, so I can see what happens from anywhere, I need it to be as cheap as possible and also as simple as possible! Thanks
