Cables for Security Cameras Available in Houston: The Importance of Selecting the Proper Cable for All Systems

A camera system cannot perform better than its cable. An outstanding 4K camera with an inferior cable would produce flicker effects, ghost images, unexpected interruptions, or even no image at all. Nevertheless, the cable is usually the last thing people consider when dealing with their security camera system. When trying to find security camera cables for sale, this article will explain everything about the types of cables available, which one to use with which camera, and which cables work in Houston conditions.

Importance of Correct Cable Selection

The cable carries both video and sometimes power from the camera to your recorder. The wrong cable will either attenuate the signal due to distance, pick up signals of the interference of the electrical wires near it, or deteriorate under the effect of sunlight and moisture in the insulation of the cable. This problem will be extremely difficult to resolve once the cable is buried in the wall or soffit.

Correct cable selection largely depends on the type of camera used. Analog and HD-over-coax require coaxial cables with BNC connectors, whereas IP requires Ethernet cables. One of the most common mistakes made during cable selection is to confuse the two types.

CCTV Camera Cables: Combination Cables (Power/Video Siamese Cables)

The cables for CCTV cameras that provide transmission via analog and HCOx technology may appear in combination cables. One end provides video transmission via the coaxial cable, while the other one supplies power via the same cable. As a result, you will have one cable from the recorder to your camera rather than two. The ends of the cable include a BNC connector for video and a DC connector for power supply.

The combination cable by Camrelo corresponds to the description above. According to the product specification, it includes BNC and DC power connectors, operates at the DC12V voltage, and supports AHD, TVI, CVI, and analog CCTV system at HD, 1080p, 2K, or 4K resolution. The cable has the following lengths: 30 ft, 60 ft, and 100 ft. Also, you can order it in a custom length. More information about security camera cables you can find on our website.

BNC Cable for CCTV Cameras

The BNC cable used for CCTV cameras consists of a bayonet coupling that twists and connects firmly to maintain connectivity and minimize signal loss. It is the preferred form of analog and HD coaxial connections and it fits a DVR system that has coaxial connections.

Consider the type of cable and the shielding when selecting the BNC cable. The RG59 cable works well with short runs whereas the RG6 cable is ideal with long runs. Double-shielded cables minimize interference by power wiring, motorized equipment, and lights. It is also important to consider the quality of the connectors because loose crimping causes flickering images.

Ethernet Cable for Security Cameras

IP cameras require the use of an Ethernet cable, most commonly Cat5e and Cat6, that connects to the network switch. The Ethernet cable provides the digital transfer of data, and in addition, some cables support the transmission of power using PoE technology. While Cat6 provides additional room for further use with higher resolution cameras and upgrading the system in the future, Cat5e is currently the most popular choice for installation.

The limitation for the Ethernet cable for security cameras lies in the maximum length of the connection between the camera and the network switch. It cannot exceed 100 meters (or approximately 328 feet). In case you are going to install IP cameras, do not use the coaxial combo cable presented above as it is not compatible with IP cameras.

PoE Security Camera Cables

PoE security camera cables are Ethernet cables, providing electricity and data transmission over the same wire. Thus, there is no need for a power outlet for each individual camera, thus making installation easier and giving you the freedom to place cameras wherever you want to. For efficient PoE functioning, select those cables which consist of copper core conductors. As far as copper-clad aluminum cables go, their high resistance may lead to voltage drop and unstable connection.

Make sure that the cable is capable of supporting the PoE standard that is being used by the cameras and switch, and keep the cable length within the recommended limits. In case of outdoor PoE cables, you should consider using the UV-resistant jacket for the outdoors.

Key Specifications of Wired Surveillance Camera Cables

Among many features of the cable, there are a few which are really important when choosing the wired surveillance camera cable. Conductors' material is an important factor, since copper gives higher conductivity compared to copper-clad aluminum. Shielding protects from electromagnetic interference, which is critical when running close to power lines. The material of jacket must be solid and the cable itself should be flexible enough not to tangle when installing. For instance, the Camrelo's cable has such parameters as double shielding, flexible PVC jacket and the range of operating temperature from -20 to 60°C.

One more feature to take into account is voltage drop in combo cables. Since DC12V power can drop in the long run, cameras might be constantly resetting or losing their night vision capability.

Cables Used in Outdoor Security Cameras

Cables used in outdoor security cameras need to withstand sun exposure, rain, humidity, temperatures, and at times, pests. Ensure that you have selected cables that are UV-protected and weatherproof with regard to their jackets. Our specification of cable shows a PVC jacket with a weatherproof jacket and is UV- and moisture-resistant. The cable can be used indoors and outdoors.

The installation of the cable may determine its longevity. Protect cables using conduits and channels when there is any exposure, seal any entry point using weatherproof junction boxes and avoid leaving your connectors in any open place, especially on the ground.

Cable Extensions for Security Cameras

Sometimes a cable might be slightly shorter than necessary. Cables for security cameras allow you to add extra length between the camera and recorder or the power supply. In the case of BNC systems, there are two options for adding extra length using either compatible cables or cable couplers to connect two cables.

Each connection is another potential point of failure; therefore, it is wise to keep the number of connections to a minimum and only use high-quality connectors. When you require multiple extensions, it may be preferable to order a custom-length cable. This is why Camrelo supplies custom lengths.

Professional CCTV Installation Cables

Professional CCTV installation cables are selected on the basis of the camera, distance, conditions and any future plans. A professional will calculate the run, select the correct cable and connectors, install the cable with care, and label all cables so that maintenance is easy in the future. They also avoid some common pitfalls, including running video cables next to high voltage wires and using incorrect connectors.
