When installing a high quality surveillance system you will want to be sure that you use a type of cctv cable that’s most conducive to your needs. So lets quickly go over a few applications and benefits of 2 different types of cable.
Coaxial Cable
Coaxial cable is the most common and the original type of cctv cable that was used for decades with analog surveillance systems. It was for a while thought that coaxial cable would be phased out in the digital age as the rise of IP camera systems became more wide spread. However in recent years HD-SDI, HD-TVI, and HD-CVI have all become viable options for digital HD surveillance, which has kept coaxial cable alive and strong. These type of systems have one major advantage in that it allows someone to upgrade their older analog surveillance system while using the same cabling that was already installed.

RJ45 Network Cable
Network cable has long been used for networks, computers, and most IT systems in general. It was however the rise of digital cctv and IP cameras that made it a very useful type of cabling for surveillance systems. By using RJ45, surveillance systems were now able to eliminate their need for a second cable run for power input. This is due to the fact that RJ45 cable has multiple cable pairs twisted together. One of these pairs can be used for the video transmission while another pair can be used for power transmission. So by having a smaller diameter cable that only requires a single run it allows for easier surveillance installation. In the end this makes it so that new surveillance installations tend to prefer using network cable as it can also be ran at the same time as IT networks are being installed.
RJ45 cable can be found in large pull boxes such as these: http://www.cu1.com/catcables.html
