If you are having lose BNC connections you may have a poorly terminated connector (attachment to cable). Or you must be careful to purchase 75 Ohm BNC connectors. About 70% of the connectors sold in the USA are 50 Ohm type BNC connectors for radio use. Sold as BNC connectors but what impedance. The 50 Ohm type connectors look just like the 75 Ohm type but they have a center pin that is larger in diameter and when mated with a 75 Ohm connector on a camera or DVR they bend the connector and permanently damage the 75 Ohm connector and makes it intermittent in a short amount of time.
