When it comes to selecting a cable for your video security camera system, the process may not be as easy as you might expect. There are several types of cable that can be used with surveillance equipment. However, the specific type of equipment you have will generally determine which cables to consider. In this article, we discuss the 6 best security camera cables and which applications are best used. After reading this article, you will feel confident that you are selecting the correct cables for your application.

Prefabricated Siamese cables, also known as prefabricated CCTV cables, are by far the most popular choice for analog CCTV cameras and HD security cameras over coaxial cameras . The reason for this is because these cables come fully assembled with BNC connectors and cut to a specific length for immediate use by customers. At one end, there is a male BNC video connector and a 2.1mm female power input (DVR / monitor side). On the other hand, there is a male BNC video connector and a 2.1mm male power outlet (camera side).
Many of our clients are not experienced camera installers and do not know how to cut and terminate the ends of the cables or fear that they cannot do it correctly. These cables give those customers the confidence to install their new camera system themselves, potentially saving hundreds, if not thousands, of dollars on a professional installation.
The pre-made Siamese cables supplied by CCTV Camera Pros are of high quality and compatible with standard analog / CVBS cameras, in addition to AHD, HD-TVI and HDCVI HD analog cameras. We have them available in lengths of 25, 50, 75, 100 and 150 feet. If you are using an analog camera with BNC connectors and do not want to cut and terminate your own cables, prefabricated Siamese cables are the ideal choice for you.
Like pre-made Siamese cables, pre-made audio, video, and power are cut to length and terminated with video and BNC power connectors on both ends. However, there is an additional RCA cable to stream audio to the DVR or monitor.
These cables allow users to add an external microphone or support a built-in microphone from one of their surveillance cameras. When using external microphones with AVP cables, we recommend using in-line surveillance microphones as they share the power with the camera and do not require additional power supplies or cabling.
The pre-made audio, video and power cables carried by CCTV Camera Pros are tested and approved to work with analog / CVBS cameras, as well as AHD, HD-TVI and HDCVI HD security cameras. We recommend AVP cables to users who use analog cameras and want to add a microphone to their system to record audio in addition to video. If you already have a microphone with a 3.5mm jack, you can use a RCA to 3.5mm converter to make it compatible with these cables.
RG59 Siamese Coaxial Cable Reels
RG59 Siamese Coaxial Cable comes in 500 and 1000 foot coils and allows installers to cut and terminate their own cable. This is the best and most recommended wiring for BNC security cameras due to the superior gauge and materials used to manufacture them.
Unlike prefabricated Siamese cables, the RG59 uses a much thicker 20-gauge cable core for video and 18-gauge cables for power. Since the meter is thicker, it can run further (up to 700 feet of video when powered locally) than pre-made cables (up to 200 feet) without interference. Also, the shielding on RG59 is thicker than on pre-made cables, making it more durable and long-lasting. The biggest benefit of cutting and terminating coaxial cable is that users can choose to install twisted, crimp, or compression type BNC, RCA, or F-type connectors rather than trying to find a prefabricated cable with its desired connectors.To learn how to cut and terminate the ends of the RG59 coaxial cable, check out our how-to videos . We also have this RG59 Siamese Cable Wiring Guide available.
The RG59 Siamese coaxial cable supplied by CCTV Camera Pros is available in black or white and has a solid copper core, 95% copper braided shield, and an impedance of 75 ohms. RG59 cables with steel / copper clad cores made specifically for CATV (Cable TV) are NOT to be used for video surveillance applications and are known to distort camera image quality if even displayed.
RG6 is very similar to RG59 coaxial cable except that the copper core is 18 gauge instead of 20 gauge and the insulation and shielding are much thicker. However, this does not mean that it is the best cable for HD CCTV security camera system applications. In fact, we always recommend RG59 over RG6, as it is more suitable for transmitting surveillance video. Since the RG59 core cable is thinner than RG6, it can transfer lower frequencies and bandwidths with less resistance. On the other hand, because RG6’s copper core is thicker, it is more suitable for transferring bandwidths and higher frequencies, such as the Internet and cable TV.When trying to use RG6 for CCTV cameras, users will find that their video may be distorted, if it appears, especially at longer distances. This is because the thicker core of the RG6 cable creates more resistance where the lower frequencies cannot beat. Therefore, it is always recommended to use RG59 over RG6 when it comes to surveillance systems.
Cable de red Cat-5e
Even if you are not a CCTV installer, you are probably familiar with Cat-5E Ethernet cable. This is the cable with the RJ45 connector that connects your internet modem to your wireless router or your PC to your wired router / network switch. The Cat-5E Ethernet cable consists of 8 individual 24-gauge or 4-pair cables. Each pair of cable is designated for a specific purpose, such as data transmission or power.
Like the Siamese cable, the Cat-5e can transmit video and power over a single cable. CAT5 is primarily used with network IP cameras in the surveillance industry. However, with the use of Video Baluns, users can use Cat-5E cable to wire analog CCTV cameras (CVBS) and HD BNC cameras (AHD, HD-TVI or HD-CVI). CCTV video baluns work by taking the signal typically transmitted over coax / siamese cabling and dividing it into multiple pairs, 1 pair for data, 1 pair for power, and 1 pair for audio, if applicable, so that it can be transmitted through Cat – Cable 5E.
This type of setup allows users to increase their transmission range from 700 ft. With Coaxial to 1,300 ft. With Cat-5E. The image above shows a CAT5 video balun used to connect a camera and DVR. You can see on the left side of the cable how the balun connects to the DVR and the security camera’s power supply.
The Cat-5E cables supplied by CCTV Camera Pros are of the highest quality with a 24 AWG pure copper base cable and 50u gold plated short body contacts making them compliant with fire and safety standards of the National Electrical Code TIA-568-C. In addition, they also comply with UL Code 444. We have them available in pre-made lengths and in 1000 foot coils.
In recent years, Cat-6 has become a very popular alternative to Cat-5E cable. While both are 4 pairs of 24 gauge cables wrapped in a shield, the Cat-6 cables are more tightly coiled and allow for faster data transmission. For example, Cat-5E can transmit up to 1,000Mbps, or 1 Gigabit, of data, while Cat-6 can transmit up to 10,000Mbps, or 10 Gigabytes, of data. However, there is a limitation. Cat-6 can only transmit 10,000Mbps up to 165 feet. After 165 feet, Cat-6 will transmit at the same 1,000Mbps as Cat-5E for the rest of the cable run.
For security cameras, we recommend using Cat-5E cabling, as no more than 1,000Mbps needs to be transmitted, even in full 4K resolution. Cat-6 is primarily intended to be used as the backbone for large network infrastructures that transmit several Gigabytes of data per second.
