BNC twist-on connectors are widely used in security camera systems to establish reliable connections between coaxial cables and cameras, DVRs/NVRs, and monitors.
Their simple twist-on design allows easy installation without specialized tools, ensuring a secure link for video signal transmission over coaxial cables, commonly RG59 or RG6 types, which are prevalent in security setups.
In this short guide, we will demonstrate how to easily, quickly, and correctly use these connectors.
Instructions for BNC Twist-On Connectors
When working with BNC twist-on connectors in security camera systems, several common mistakes should be avoided to ensure a reliable and effective connection:
Step 1: Begin by trimming back the outer shielding of the coaxial cable, leaving approximately one inch exposed.
Step 2: Gently separate and spread apart the copper braid, ensuring it does not overlap.
Step 3: Trim the copper braid, shortening it by half of its original length.
Step 4: Carefully cut the white insulation to a quarter-inch length, exposing the inner components.
Step 5: Trim the center copper conductor to approximately two-fifths of an inch, providing a proper contact surface.
Step 6: Take the shortened copper braid and skillfully wrap it around the exposed white insulation. It’s crucial to maintain separation between the copper braid and the center copper to prevent signal interference.
Step 7: Conclude the process by securely attaching the BNC Twist connector onto the cable’s end. Rotate the connector until it is firmly fastened in place.
By following these steps, you can confidently establish a stable and interference-free connection using BNC twist-on connectors in your security camera system.
Here are some common mistakes that you should avoid:
Overlapping Copper Braid: Allowing the copper braid to overlap or come into contact with the center copper conductor can cause signal interference and degrade video quality.
Insufficient Cable Insertion: Not fully inserting the cable’s components into the BNC connector before twisting it on can lead to an unreliable connection and potential signal loss.
Overtightening the Connector: Applying excessive force while twisting on the BNC connector can damage the connector threads or the cable, affecting the integrity of the connection.
Dirty Connectors: Connecting BNC connectors with dirt, dust, or debris on the contact surfaces can hinder signal transmission and result in intermittent or poor connections.
