What cables to use for security cameras installation?

Updated: Nov 16


Installing security cameras at your home or business is the best deterrent against a potential break-in or vandalism. There are different types of systems out there on the market.

What system should you purchase and what cables are better suited for security cameras installation?


While installing wireless security cameras is more affordable and easier, consumers face some drawbacks such as a lack of direct power source, remote hacking, signal interference, and low resolution. The only drawback linked to wired solutions is fixed locations, making cabling a fundamental aspect in today’s surveillance systems.


You need to make sure to choose the right type of cable for your video surveillance security cameras system. However, it’s important to understand the properties of different cables and connectors how they work with surveillance systems to maintain efficiency and effectiveness. This article will help you buy and install the right camera cables for your surveillance system.





Coaxial cables (Siamese Cables)


With Siamese cable you will have two different cables connected together into one cable, allowing you to power your video surveillance cameras receive video signals using one cable run. RG-59 Siamese cables are often used for analog or digital (TVI) security cameras systems that use a BNC connector on both ends to connect cameras to the receiver (Digital Video Recorder - DVR). To connect this security camera wire type to Digital Video Recorder, you’ll need to separate the cables for their intended use at the end of the cable run.


The Siamese RG59 cable contains 2 cables in one: an actual video cable (RG59) and a power cable that has black and red cables inside. This cable is called 18-2 power cable and it is a part of the Siamese cable that is used to power your CCTV security cameras.

These wires should be connected to a 12 voltage power source. The coaxial RG 59 cable is the larger cable, and its purpose is to connect your analog video camera to a DVR system (Digital Video Recorder), which allows the reception of video signals from security cameras.

This type of cable can be installed in residential homes and businesses of any size. It is not recommended to use Siamese cables for large industrial installations where the distance between CCTV security video surveillance camera and Digital Video Recorder exceeds 500 feet as it may the video signal quality and there may be interference on video signal of your security cameras.


Ethernet (CAT5 or CAT6) cables


If you’re installing an IP video surveillance system or IP security camera you’ll need an Ethernet cable. 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 using Network Video Recorder (NVR). 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. Before purchasing an Ethernet cable, you need to do research as there are few different types of Ethernet cables on the market: CAT5, CAT5e, CAT6 cables.



Ethernet cable is used to transmit video signal and power up your POE enabled IP video surveillance cameras. The IP video surveillance systems can be used at homes, businesses, and large scale industrial installations. Quality IP video surveillance systems are generally more expensive than Digital HD CCTV security cameras systems.
