What kind of cable do security cameras use?

When the installation team at A1 Security Cameras prepares to implement a security camera system into a home or business in DFW, we consider many parts and features before implementing any device. Not the least of which are the cables that run both power and data throughout a security apparatus. Security cameras, and many other parts of a given system, can use different types of cables depending on the nature of the device, with examples being:

  • Coaxial
  • BNC
  • Ethernet
  • RCA
  • Powers
  • Siamese

Each of these lines is distinctly unique in design. While some may function similarly to others, all serve a distinct function in a security camera system. Therefore, when you reach out to our team and request design help, we consider these cables an essential detail. Below for your consideration and convenience, we have provided a detailed overview of each of the above cables and what they may do in a security apparatus.

How expensive is running cable for a security system?

The acquisition and running of cable is generally the most expensive part of installing a security camera system. However, for simple and straightforward installations, the cost is typically reduced. Such can be seen in the case of wireless cameras, which only require power cables. Distinctly, features that define the price include:

  • Infrastructure
  • Length of wire
  • Protection
  • Walls
  • Visible vs. hidden

Each of these provides detail into how wires are set up throughout a structure, supporting each device by either delivering power, transferring video footage, or issuing commands after configuration on a central recording device. Those functions play into the value of the wires, while the list above considers the value of how they are set up. Walls, for example, must be drilled through. The infrastructure also plays a role; whether someone has a small one-story house versus a warehouse, for example, will produce a price difference. Furthermore, outdoors vs. indoors installations have their own parameters like protecting the exterior wiring placed. For exact pricing on a specific installation or how much it will take to get your precise security camera system implemented, A1 Security Cameras offers design help. Through this process, an experienced professional can answer each of your questions, and you can have a complete understanding of what will be undertaken before any work starts.

What are coaxial cables?

What are coaxial cables?

Also commonly referred to coax, these cables are designed to carry analog data, video footage, internet, and more. Made up of copper wiring, copper mesh, sometimes foil, dielectric, connectors, and insolation, these wires are generally used with analog cameras and recorders like digital video recorders. RG59 and RG6 are the current industry standard as of the time of writing.

What are BNC cables?

Standing for Bayonet Neill-Concelman, BNC cables were used similarly to coaxial cables to connect analog security cameras to recorders. However, these wires are similar to coaxial cables in design but are smaller, which in turn reduces the effectiveness for larger and current security devices. While still used somewhat today, they have been phased out for modern coaxial cables and ethernet.

What are ethernet cables?

Ethernet cables are used to carry broadband signals and electricity between devices. Internally, ethernet cables are twisted copper wire pairs surrounded by insulation with color designations and then a jacket. More advanced designs typically mean more copper wire and installation or them being situated more affectively than the predecessor. Cat5e cables, for example, feature four pairs of copper wires to transfer data. The industry standard at the time of writing is Cat5e and Cat6. The cables are typically used to transfer data between internet protocol cameras and network video recorders.

What is the best of the three cables for security cameras?

If one of our installers were to reach a location and learn that BNC was used, they would suggest upgrading to coaxial or ethernet. The reason behind such a suggestion is that BNC is weaker than the more modern alternatives. The decision between coaxial and ethernet depends on what type of system you want. Previous and long-lasting systems use analog while newer and more advanced systems use ethernet. Systems that use coaxial are typically more inexpensive, while ethernet systems offer more features but are more expensive. A1 Security Cameras has provided a guide detailing the features in base to fully upgraded systems for a more detailed analysis on the subject.

What are RCA cables?

What are RCA cables?

Standing for Radio Cables of Americans, these cables are used to carry audio and video signals. Defined by the colored opposing ends around the ports or jacks, these wires feature copper and insulation. They are commonly used in various electronics, including audio surveillance and other devices of the same function.

What are HDMI cables?

Also standing for high-definition multimedia interface cables, HDMI cords are becoming the standard for both digital and audio in electronics. In addition, many network video recorders use them as a means to connect to monitors, as do computers, gaming consoles, and more likewise do. Internally, HDMI cables are far more complex than coaxial and ethernet cables, having sophisticated jacks and inputs to carry high-definition data.

What are siamese cables?

In the security camera industry, siamese cables feature both a power cable with a coaxial cable twisted or stuck together. Typically, the siamese cable matches the industry standard of the coaxial and is near the exact same internally. These wires are commonly used with analog security cameras and digital video recorders.

How are security cameras and recorders powered?

Typically, security cameras and recorders use devices called transformers that plug into wall sockets to power them. Such devices feature electrical wiring and a bulky shape designed for the electrical outlet. This shape filters the incoming electrical current and makes it more manageable for the designated device.

How are security cameras and recorders powered?

Do cables need to be protected?

Yes, especially when installed outdoors. Cables inside may survive the test of time but can be tripped over or accidentally damaged from daily activities like vacuuming. However, outdoor wiring is subject to the elements, all manner of animals, plants, and can be viewed as a target by malicious parties. Therefore, our professional installers typically put a hard casing around wirings that cannot be run through walls.

What is Power over Coaxial?

Power over coaxial or PoC for short is a simple concept that allows both power and video data to be streamed through the same coaxial cable. The process works by using the already in place over-current protection function found in industry-standard RG59 coaxial cables. While some devices are not capable of using such a function, PoC analog cameras are designed to do so. As a result, such cameras require less wiring and are more efficient in power consumption. Such cables can also be extended with PoC extenders.

What is Power over Ethernet?

Power over Ethernet or PoE cables transport an electrical charge, video footage, and audio data all in the same cable. This means that security cameras no longer need power cables but can be charged directly from the NVR, PoE switch, or computer. Furthermore, such a connection can be lengthened through the use of PoE extenders.

Are all security camera cables the same?

As shown, no, each security camera cable is different in internal design. Coaxial cables, for example, transport analog data while ethernet cables transmit digital data. Furthermore, unlike their predecessors, industry-standard coax and ethernet can also transport electricity, making installation far more efficient than ever before.
