CCTV cable is most commonly just a simple piece of RG59 coaxial cable that is ran between your security camera and DVR or any other video viewing devices. The RG59 coaxial cable type is the best choice coaxial cable type for video transmission in a CCTV application. CCTV cable is really the common term that encompasses the cable and its use. In order to make a CCTV cable you will need to terminate the RG59 cable with male BNC connectors on each end. Both your DVR (Digital Video Recorder) and security camera both come equipped with built in female BNC connectors for the connection. The two most common types of BNC connectors used when building a CCTV cable are compression type and crimp type. Although both styles will create the connection you are trying to make there are positives and negatives to each solution.
• Crimp Type BNC Connectors for CCTV Cable:
A crimp style BNC connector is the most cost effective solution for attaching a BNC connector to your coaxial cable. The crimp mechanism of this BNC type uses a crimp tool to crush the metal sleeve of the connector in a way that it is attached to the coaxial cable. Although the crimp style solution gives you and inexpensive option it is not known as the most durable, secure, or long lasting way to terminate CCTV cables. Since a crimp is essentially crushing a connector around a cable it leaves room for moisture to get in and over time you may have connectivity issues. Also, over time the crimp begins to loosen and eventually the cable may disconnect from the connector. The end result of any poor connection will be poor video quality and eventual signal loss. The majority of all CCTV cable and CCTV system issues are crimp connector related.

Are you looking for a way to install cables for your CCTV cameras without buying tools, bulk cable, and connectors to do all the work? If so buying premade CCTV cables might be the best solution for you! Premade CCTV cables are basically your Siamese CCTV cable that is pre-terminated with connectors already on it so all you have to do is just plug your cameras in and you are ready to go! Premade CCTV cables are perfect for the person that is installing a system at their home or business and they just don’t want to invest in all the tools and supplies to make the cables on their own! All you have to do is measure the CCTV cable runs you need and choose the premade CCTV cables that support those cable run distances. Most premade CCTV cables are offered in black or white and in numerous lengths to support most camera cable distances.
Quality premade CCTV cables feature both the RG59 coax cable and the 18/2 power cable together in one easy to pull Siamese cable solution. The power cable of a premade CCTV cable has molded power connectors pre-installed that allow you to easily plug in a transformer to power your cameras. If you are using a central multi-channel power supply you can simply cut the connector off the power side and screw the power cable directly down on the terminal blocks located on the power supply. On the opposite side of the power supply there is also a power connector that allows you to simply install it right to the camera. On the coaxial cable of a premade CCTV cable you will have molded compression BNC connectors terminated on both sides. So one end of the RG59 coaxial cable will connect to your DVR via the BNC connector and the same will happen on the opposite side to attach to the security camera. So premade CCTV cables create a plug and play installation for you and save you time and money because you are not out there spending your time putting connectors on the ends of all your cables!
