Setting CCTV cameras up, however, can be a little complex. You need to know the rights and wrongs of CCTV camera connection before you can enjoy full security benefits. To make learning easier for you, we’re going to walk you through everything you need to know in the following sections.

CCTV Security Camera Connection Types

Before we start, let us first walk you through the basic CCTV security camera connection types and basis. It’s important that you’re fully acquainted with this before moving on to the step-by-step guide. Doing so will help you avoid being confused throughout the tutorial.

To start, here is a reference:

  • Coaxial Cables – Coaxial cables are the easiest ones to install because it fits both small and large CCTVs. It’s also commonly used because of shielding and protective copper-based qualities. Using this isn’t limited to a specific place so that it can be for both indoor and outdoor CCTVs.
  • Video Power Cables – Video power cables, also known as Plug and Play, are a viable option if you’re looking for cables that are affordable, user-friendly, and easy to install. This is best for CCTVs that don’t require a very lengthy cable connection.
  • Siamese Cables – If you plan on installing several CCTV cameras, then Siamese cables will be perfect. These consist of dual wires, which assure better signal and interference. Thus, even when monitoring several security videos, you can still expect clear screenplays.
  • Optic Fiber Cables – For offices and workplaces, connecting CCTVs through optic fiber cables is the best choice. These cable types provide high levels of sugar and transmission, which can cater to more cameras while still retaining playback quality.
  • RG-59 – Now, for residential CCTV cameras, using RG-59 cables is the answer. With super gas-injected insulation, this ensures a relatively good signal for apartments, flats, and even 2-story homes.

In choosing a cable and overall connection type, take the purpose of the CCTV into account and where you plan on placing it long-term. You can finish the IP camera configuration and connection job within just several minutes.
