I have worked in the security industry for 37 years and have used different types of BNC connectors. These work for my purpose of connecting "dummy" cameras, but this type can be problematic when trying to establish and maintain a good connection. I prefer the type where the center pin is also crimped onto the conductor. I bought them because they were the cheapest.
