What Type of BNC Connector is the Best? Leave a comment


BNC connectors are used in conjunction with RG59 and RG6 coaxial cables. They are the CCTV industry standard for video surveillance systems. Note: almost all CCTV devices, cameras, surveillance systems, DVRs and monitors have BNC female connection. Therefore, you will most likely need BNC male connectors on both side of the cable. There’s no universal answer here, if there were, only one type of BNC connector would exist. One factor to consider is your prior experience, if you have gotten comfortable installing a specific kind, you may want to stick with it. So let’s take a look at the different kinds and their possible pros and cons.

Type 1- BNC Crimp-on Connector

BNC crimp-on connectors come in either a two or three piece configuration. The two piece is more common and requires two tools for proper connection. A coax cable stripper to prep your cable, and a coax crimper to attach the connector securely. This process is a little more time consuming but will create a secure connection that lasts. After you properly strip your coax cable for prep, these attach directly to the cable. They are then crimped into place for a snug and secure hold.

Type 2- BNC Twist-on Connector

Twist on BNC connectors are a simpler and do not require any special tools to install. You will still need a coax cable stripper to prep the wire, but the rest is done by hand. Some users have reported that these are not as secure as a crimp-on connection; however, when cut properly, BNC twist-on connectors can be very secure. It is important to trim the coax cable to the proper length according to the size twist-on connector you are using. After stripping the wire for prep, the user simply twists on the connector over it until a snug fit is reached.

Type 3- F Compression Connector to BNC

Compression connectors are probably the most secure when attached to a coax cable. Unfortunately, the required compression tools are not cheap. These connectors also add extra length that will need to be factored in and may not be viable in tight locations. This is because you attach the compression F connector to the coax cable and then screw on a BNC connector to the F connector. This allows the installer to trim the coax core to the correct length after it is installed.   

Type 4- F Crimp Connector to BNC

F crimp connectors to BNC works similarly to type 3. An F connector is attached to a coax cable first, then a screw- on BNC connector is attached to the F connector. Again, this presents a total longer package and may be an issue in locations with limited space. This method provides similar security without the need for costly compression tools. Though, it should be noted you will still need a coax cable stripper to prep the wire.
