Security camera cables are the unsung heroes of any home security camera or CCTV security camera system. Without them, the cameras would be nothing more than expensive paperweights. These cables transmit both video and power signals from the camera to the recording device, such as a DVR.
There are different types of security camera cables available in the market, including video power cables and play cables. Video power cables combine both video and power wires into a single cable, making installation easier and less cluttered. Play cables, on the other hand, only carry video signals and require separate power cords.
The length of the cable is an important consideration when setting up a security camera system since it determines how far away from the recording device you can place your cameras. It’s essential to measure distances accurately before purchasing your cables to ensure they’re long enough for your needs.
Cable clips can be used to secure the cables in place and prevent them from being accidentally unplugged or damaged. These clips come in various sizes and shapes to accommodate different cable thicknesses.
CVI (Composite Video Interface) is a type of security camera cable that allows for high-definition video transmission over long distances. This technology enables users to transmit high-quality videos without sacrificing signal quality or resolution.
Choosing the Right Security Camera Wiring Types
Understand the Different Types of Security Camera Wiring
There are mainly two types of wiring used for security cameras: coaxial cables and twisted pair cables. Coaxial cables are thicker and more durable, while twisted pair cables are thinner and more flexible. Both types of wiring have their own advantages and disadvantages, so it’s important to understand which type is best suited for your needs.
Coaxial Cables
Coaxial cables consist of a copper core surrounded by layers of insulation, shielding, and an outer jacket. They are commonly used for long-distance transmission of video signals because they have better signal strength than twisted pair cables. Coaxial cables can transmit data over longer distances without losing quality or experiencing interference.
Twisted Pair Cables
Twisted pair cables consist of two insulated wires that are twisted together in a helix pattern. They are commonly used for short-distance transmission of video signals because they are thinner and more flexible than coaxial cables. Twisted pair cables also cost less than coaxial cables, making them a popular choice for small-scale installations.
Consider the Distance Between the Camera and the Recorder
The distance between the camera and the recorder will determine the type of wiring needed. For longer distances, coaxial cables are recommended as they have better signal strength and can transmit data over longer distances without losing quality or experiencing interference. Twisted pair cables may be suitable for shorter distances but may not provide optimal performance over longer distances.
Think About the Environment Where the Wiring Will Be Installed
The environment where the wiring will be installed is also an important factor to consider. For outdoor installations, weather-resistant wiring such as shielded twisted pair (STP) or outdoor-rated coaxial cables should be used. These types of wiring can withstand harsh weather conditions such as rain, snow, extreme temperatures, and UV exposure.
Determine the Power Requirements of Your Security Cameras
Some security cameras require power to be transmitted along with data, while others have separate power sources. If your cameras require power to be transmitted along with data, you will need to use Siamese cables which have both power and data wires. Siamese cables are commonly used for CCTV installations because they simplify the installation process and reduce the amount of wiring needed.
Choose a Reputable Brand for Your Security Camera Wiring
It’s important to choose a reputable brand for your security camera wiring to ensure that you get high-quality products that are reliable and durable. Look for brands that have good reviews and ratings from other customers. Some popular brands include Belden, Honeywell, Leviton, and Panduit.

Coaxial Siamese Cable Connectors and Advantages
Reduced Installation Time and Improved Signal Quality with Coaxial Siamese Cable Connectors
Siamese cable connectors are a popular choice for security camera systems due to their ability to transmit both video and power signals over a single cable. This design makes installation easier and more efficient, as it eliminates the need for separate cables for power and video transmission. In this section, we will discuss the advantages of using siamese cable connectors in security camera systems, focusing on RG59 siamese cable as an example.
RG59 Siamese Cable: High-Quality Shielding for Clear Video Signals
RG59 is a type of coaxial cable that is commonly used in security camera systems due to its high-quality shielding and ability to transmit clear video signals over long distances. The RG in RG59 stands for “radio guide,” indicating that this type of cable was originally designed for use in radio frequency (RF) applications. However, it has since become widely used in CCTV (closed-circuit television) systems due to its excellent performance characteristics.
One advantage of RG59 siamese cable is its high-quality shielding. The outer layer of the cable is made from braided copper wire or aluminum foil, which provides excellent protection against electromagnetic interference (EMI) and radio frequency interference (RFI). This shielding helps to ensure that the video signal remains clear and free from distortion, even when transmitted over long distances.
Another advantage of RG59 siamese cable is its ability to transmit clear video signals over long distances. This is due in part to the quality of the coaxial construction, which consists of a center conductor surrounded by insulation, a metallic shield, and an outer jacket. The combination of these layers helps to minimize signal loss and maintain signal integrity over longer distances.
Advantages of Using Siamese Cable Connectors
There are several advantages to using siamese cable connectors in security camera systems. One of the main advantages is reduced installation time. Because siamese cables transmit both power and video signals over a single cable, there is no need to run separate cables for each signal. This can help to save time during installation, especially for larger systems with multiple cameras.
Another advantage of using siamese cable connectors is improved signal quality. By transmitting both power and video signals over a single cable, there is less chance for interference or signal loss compared to using separate cables for each signal. This can result in clearer video signals and more reliable performance from your security camera system.
Finally, using siamese cable connectors provides increased flexibility in system design. Because both power and video signals are transmitted over a single cable, it’s easier to install cameras in locations that may be difficult or impossible to access with separate cables for each signal.
Attaching BNC Male Twiston Connectors to RG Cable
BNC connectors are widely used in security camera systems to transmit video signals over RG59 cable. These connectors provide a secure and reliable connection between the camera and the recording device. Attaching BNC male twist-on connectors to RG59 cable is a simple process that can be done without any special tools.
To attach the connector, strip the RG59 cable’s outer jacket and shielding to expose the inner conductor. The first step is to measure about 1/4 inch of the RG59 cable’s outer jacket from its end using a wire stripper. Make sure not to cut too deep into the insulation as it may damage the inner wires.
Once you’ve stripped off enough of the outer jacket, you’ll need to remove about 1/4 inch of shielding from around the inner conductor. This can be done by twisting and pulling away from the center conductor until it comes free.
After stripping off both layers, you should see a copper-colored wire in the middle with white insulation around it. Twist this wire tightly together so that it forms a single strand.
Insert this single strand into your BNC male connector while holding onto its body firmly. You should feel resistance as you push it in, but continue pushing until it clicks into place.
Now twist on your BNC male connector until it is secure. You will feel some resistance as you turn it clockwise, but keep going until you cannot turn anymore.
If using RCA adapters or PNP cables, make sure they are compatible with BNC video signal and RG59 cable. RCA adapters are commonly used for audio connections, but they can also be used for video if they have enough bandwidth capacity (75 ohm impedance). PNP cables are another option for connecting cameras to recorders without using separate power supplies or cables.
It’s important to note that there are different types of BNC connectors available in terms of their impedance, size, and gender. BNC male connectors are used for output signals while female connectors are used for input signals. Make sure you have the correct type of connector before starting your work.
In addition to BNC connectors, there are also other types of connectors available that can be used with RG59 cable such as F-type or RCA connectors. However, these connectors may not provide the same level of reliability and security as BNC connectors do.
RG59 cable is a popular choice due to its affordability and compatibility with most systems. This cable has a 75 ohm impedance which makes it ideal for transmitting video signals over long distances without losing quality.
RG59 cables come in different sizes ranging from 20 AWG (American Wire Gauge) to 18 AWG depending on the length and application requirements. The thicker the cable, the less resistance it will have which means better signal quality.
