How Far Can Security Cameras See?
There are security camera cable types available in the market, each with its own features and benefits. Here are some of the most common CCTV cable types and factors to consider when choosing the right one for your camera:
Coaxial Cable
Coaxial cables are commonly utilised in CCTV systems to transmit video data. They consist of a copper core, surrounded by insulation, a braided shield, and an outer jacket. The coaxial cable is designed to transmit analog video signals with minimal signal loss and is available in different grades depending on the required transmission distance. The most common grades of coaxial cables used in CCTV systems are RG59, RG6, and RG11. RG59 is the most widely used grade, offering a transmission distance of up to 200 meters, while RG6 offers a longer transmission distance of up to 300 meters.
Ethernet Cable
Ethernet cables are those security camera wiring types that are commonly seen in IP camera systems, where digital signals are transmitted over a network. Ethernet cables are available in different categories such as CAT5, CAT6, and CAT7, each with different data transmission rates and distance capabilities. CAT5 is the most common grade, offering a data transmission rate of up to 100Mbps and a maximum transmission distance of up to 100 meters. CAT6 offers a higher data transmission rate of up to 1Gbps and a maximum distance of up to 100 meters. CAT7 offers a data transmission rate of up to 10Gbps and a maximum distance of up to 100 meters.
Fiber Optic Cable
Fiber optic cables are designed for transmitting video signals over very long distances. These security camera connector types consist of a glass or plastic core, surrounded by cladding and an outer jacket. Fiber optic cables transport signals using light, which is impervious to electromagnetic interference, making them very secure. However, they are expensive compared to other types of CCTV cables and require specialized installation and maintenance. Fiber optic cables are available in different types, including single-mode fiber and multi-mode fiber, depending on the required transmission distance.
Power Cable
Power cables are used for providing power to the camera and other components of the CCTV system. These types of security camera connections consist of copper wire, surrounded by insulation and an outer jacket. Power cables are available in different gauges, with larger gauges required for longer distances. The most common gauge used in CCTV systems is 18AWG, which is suitable for distances of up to 100 meters. However, larger gauges may be required for longer distances, and for powering multiple cameras.
How Do I Know What Security Camera Wire Types I Need?
To determine the type of cable you need for your CCTV system, there are a few factors you should consider:
- Camera Type: Different CCTV cable types are required for different types of cameras. Analog cameras typically use coaxial cables to transmit video signals, while IP cameras use Ethernet cables to transmit digital signals.
- Transmission Distance: The distance between the camera and the recording device is an important consideration when selecting a cable. Coaxial cables can send analogue signals up to 300 meters, whereas Ethernet connections can provide digital data up to 100 meters. For longer distances, fiber optic cables may be required.
- Signal Type: The type of signal that needs to be transmitted is also an important factor. Analog signals require coaxial cables, while digital signals require Ethernet cables. Fiber optic cables can be used for both analog and digital signals.
- Budget: The cost of the cable is also an important consideration. Coaxial cables are typically the least expensive alternative, while Ethernet and fiber optic cables are more expensive.
- Environment: The environment in which the cable will be installed can also impact the choice of cable. For example, if the cable will be exposed to extreme temperatures, moisture, or other environmental factors, you may need a cable with additional insulation or shielding.
In addition to these factors, it's important to choose security camera connection types that are compatible with your camera and recording device, and that have the necessary connectors and wiring. You may also want to consider the quality of the cable, including factors such as shielding, insulation, and connector quality, to ensure reliable transmission and minimize interference.
Ultimately, the choice of CCTV cable types will depend on the specific needs of your CCTV system, and it's important to carefully consider all of the factors involved to make the best choice for your particular situation.

Note that the maximum resolution and bandwidth values in this table are approximate, and may vary depending on the specific CCTV connectors types and the quality of the installation. Additionally, the actual resolution and bandwidth requirements of your CCTV system will depend on a variety of factors, including the number of cameras, the recording quality, and the distance between the cameras and the recording device. It's important to carefully consider your specific requirements when selecting a cable for your CCTV system.
