The current standard provides for an impedance of 75 ohms for all components of video surveillance systems; today unfortunately most of the connectors used (usually oriental imported and of low cost and quality) are designed for an impedance of 50 ohms (old standard of professional video systems). This difference creates a disturbance in the passage of the signal through the same connector, with a sure degradation of the signal itself. The visible difference between a 50 ohm and a 75 ohm BNC lies in the white dielectric that can be seen inside the head of the BNC: the 50 ohm connectors have the dielectric that comes flush with the front opening, while the connectors at 75 ohms have the dielectric recessed (see the picture aside) All our BNC models are designed with an impedance of 75 ohms (dielectric recessed) and made with the utmost attention to every detail. It is important to choose a good quality connector so as not to make the investment made on the
