Understanding the Different Security Camera Wire Types

Choosing the right security camera wire types or cabling is critical to ensure your security camera system functions properly. However, it’s important to understand the properties of different cables and connections and how they work with surveillance systems to maintain efficiency and effectiveness. This guide will help you buy and install the right camera cables for your surveillance system. Learn more about the different security camera cable types here.

Siamese Coaxial Cables 

These are two different cables connected together, allowing you to power security cameras and receive video signals using one cable run. RG-59 Siamese cables are often used for analog or HD-over-coax security cameras that use a BNC connector. To connect this security camera wire type to a surveillance system, you’ll need to separate the cables for their intended use at the end of the cable run. After separating the cables, you’ll notice that one cable contains two copper wires, which are intended to power the security cameras. 

These wires should be connected to a 12 voltage power source. The coaxial cable is the larger cable, and its purpose is to connect your analog video camera to a DVR system, which allows the reception of video signals from security cameras. It’s worth noting that there are two types of siamese coax cables: pre-made or prefabricated cables that come with end connectors and varying lengths, and spool siamese coax cables, which come without pre-made connectors so users need to put a connector at the end and cut at any length based on their needs.

Ethernet Cables

If you’re installing IP security cameras, you’ll need an ethernet cable. However, you may still want to invest in these security camera wire types even if you’re setting up an analog system. Ethernet cables contain up to four pairs of insulated copper wires twisted around each other to reduce signal interference. The intended use of ethernet cables, also referred to as network cables, is connecting devices to a network of things. 

The network connectivity provided by ethernet cables enables you to easily access and manage security cameras via a network video recorder. You can also use an ethernet cable to power your security cameras. Although these security camera cable types serve the same purpose, they’re not the same. When buying ethernet cables for your security camera installation, you must consider some aspects, including the speed of the internet and type of router to ensure you choose the right cables between Cat5, Cat5e, Cat6, or newer versions.

Choosing the right security camera wire type plays a significant role in determining the correct installation for your surveillance system. IP cameras need ethernet cables while HD-over-coax and analog CCTV cameras need coaxial cables.
