Buy The Right BNC Connectors For The Job!

July 10 2013

BNC connectors are the most common connector type used to terminate and attach RG59 coaxial cable to both a security camera and a CCTV DVR. Since most DVR's and security cameras have female BNC connectors on them, a male BNC connector is needed to create the required connections for the cable to connect to both devices. In a security camera installation the RG59 coaxial cable is used to deliver video from the security cameras to the DVR. When you buy RG59 coaxial cable it is usually in bulk form and comes on a spool or in a box. But since the cable is in raw form you will have to eventually put BNC connectors on the ends. Although the marketplace is flooded with different types of BNC connectors, there are really just two major types which are crimp and compression style BNC connectors. In this article I want to explain why compression BNC connectors are absolutely the best for ensuring your entire surveillance system performs to it maximum potential.

Many people do not realize this but 75% of all security camera and CCTV system issues are connector related. The connectors are the first components that start to give which eventually causes cameras and video signals to fail, so there is no doubt that choosing a BNC connector that is built to last is crucial. In the old days all there was were crimp style BNC connectors. A crimp BNC connector is essentially a metal connector that includes the BNC head connection and a sleeve that is crimped to the cable. When crimping a connector to a cable you are using a crimping tool which basically crushes and deforms the metal sleeve onto the cable. The problem with crushing metal is that it is not a perfect connection, plus when crushing metal it leaves numerous openings where moisture and dust can enter the termination. Overtime not only does the metal loosen from the cable, but the moisture and dust that enters the connections start to hinder the performance of the cable. 

A compression BNC connector is the opposite from the crimp BNC connector because you are now compressing a sleeve onto the jacket and creating a complete 360 degree clamp. The 360 degree clamp leaves no room for any dust or moisture to enter the connection. The compression BNC connector usually has twice the pull force and it is completely air and moisture tight. So now you are getting a termination that can withstand even the toughest environmental conditions, while being built to last. A compression BNC connector will provide maximum performance and protection for both indoor and outdoor surveillance applications. So for outdoor security camera installations you will always want to fully protect your system and its connections by using compression BNC connectors! 

There is no doubt the compression BNC connectors are the best for CCTV system installations. Although the compression connectors and the tools to install them are almost double the price of the crimp style, in the long run you are saving time and money. Plus you are ensuring your surveillance system is always performing and protecting your home and business. Which is why you made the investment in the first place? So when planning your surveillance system installation, make sure to use the right parts for a successful installation. You never want a small component like your BNC connectors to cause your system to under-perform or fail!
