IP Camera Cable Color Codes

IP Camera Cable Color Codes Overview

An Ethernet cable serves two roles in an IP camera system: it transmits video data across networks and also supplies power directly to cameras; there are 2 spare twisted pairs on an Ethernet cable which may be used as power carriers.

Analog systems typically utilize shielded RG59 siamese BNC cables that combine coaxial signal transmission with power for one connector; digital IP systems use CAT5e/CAT6 ethernet cables that transmit video/audio data and power their camera simultaneously.


Security camera cables contain electrical power lines to provide power for running the camera and network, often known as security cam cables or power wires. Analog CCTV systems employ power wires from these cables for use, but IP camera wiring with signal converters as part of an Ethernet over Coax system also uses these wires. In analog systems, siamese cables combine coaxial video signal and power into one casing, commonly known as an RG59 siamese cable, and often shielded to reduce signal interference.

IP cameras use ethernet cables (sometimes called network cables) to connect them to an NVR or PoE switch. The cables allow both data transmission and power delivery over one cable – known as Power Over Ethernet or PoE – thereby simplifying wiring without the need for separate power and video cables. Most IP cameras can be powered using PoE switches, but some require external sources of 12V DC power adaptors for power.

Ethernet cable colors are usually indicated on the outside jacket of the cable with a code to identify its type; alternatively, these codes may also be written on its RJ45 plug (also called keystone jack).

There are various kinds of Ethernet cables; among the most widely used are Cat 5 and Cat5e cables. These contain four pairs of copper wires twisted together, creating a twisted pair that minimizes noise and provides high-speed digital signaling connectivity. They’re color coded so you can quickly distinguish each wire and its corresponding connectors.

Crimping RJ45 connectors on network cables must adhere to standard 568B in order to guarantee correct connections of twisted pairs and allow them to carry high-speed digital data signals required by IP cameras or other network devices. Failing to follow this standard may result in the cable not functioning, leading to connectivity issues between network devices.


Ethernet cables are among the most frequently utilized wires when it comes to IP cameras, serving two major purposes – connecting and powering them. They do this using similar methods as your home internet – sending packetized video over wires while also acting like your home wiring system powering devices.

Instead of using separate wires for audio and video transmission, this hardware encodes them into a data stream that travels over an ethernet cable to your network where higher-level protocols such as IP can access it.

An ethernet cable contains eight wires/pins numbered 1 through 8. Hold an RJ45 connector with its copper side facing upward to identify where each wire belongs and start counting from the left. Each pin on the outside of the connector has been labeled with its number; these correspond with specific color wires within the cable.

Note that when running a twisted pair wire cable, at least 6 inches should separate it from other electrical wiring, in order to reduce signal interference and ensure optimal video and audio streaming quality. Any closer could cause signal jamming, which prevents camera functions from working correctly.

Another option for powering security cameras is using a Siamese cable (also referred to as coaxial cable). This combines video transmission and power supply into one cable; one popular option is RG59’s siamese cable which has sufficient thickness to carry video over reasonable distances while remaining thin enough for easy installation.

Ethernet cables can also provide power to security cameras if equipped with a special adapter called a power over ethernet (PoE) adapter, available from most major online security camera suppliers and designed to connect directly to an ethernet cable’s endpoint.


Some security camera systems use a separate audio wire to transmit sound, while others can simultaneously record both video and audio. To determine whether your camera supports audio capabilities, check its product description on its manufacturer’s website; alternatively, consult with a security professional to find one that suits your requirements.

Analog systems tend to use RG59 siamese cable for video signal transmission and power supply, featuring both BNC connectors for transmitting video signals and male power terminals. Although pre-made cables may be convenient, they may not fit perfectly into your installation site or meet camera specifications precisely; additionally, these types of cables don’t come shielded and may be susceptible to electromagnetic interference.

Digital IP systems typically rely on CAT5e or CAT6 ethernet cables to connect each camera to an NVR (Network Video Recorder). These shielded cables carry more data than un-shielded versions and are thinner and easier to work with than coaxial siamese cables, making them more cost-effective options than coaxial siamese versions.

These ethernet cables not only connect your NVR and camera together but can also power each camera using Power over Ethernet (PoE) technology. To activate this function on your network, a PoE switch must first be installed; once activated it can distribute power directly over each ethernet wire to power each camera connected by them.

For your security camera to utilize ethernet cable, a special RJ45 connector with eight pins and conductors designed to accommodate this form of wiring will be needed. This RJ45 plug features color-coded strips on the plug that correspond to each pair of twisted copper wires found within these cable types; see this Dahua pinout and wiring diagram to identify which color wire goes to which pin on an RJ45 plug; it uses brown for pin 1, purple for 2, orange for 3, yellow for 4, and blue pin 7/8.

Data or Control

IP camera cables serve two roles; connecting to your network to send video data back to the recorder and powering the camera itself. These types of cable, known as Ethernet wires, have been specifically engineered for networking use to transmit packetized data such as audio/video content encapsulated within packetized Ethernet signals – however, this content is encoded directly within this packetized data stream rather than being sent separately over wires.

Cat5 cable and Cat5e cables are among the most widely used ethernet wires, offering eight wires in four pairs twisted together in four twisted pairs for use over short or long distances. Both varieties can come with shielded and unshielded options depending on how the cables will be utilized; unshielded versions can run up to 330 feet (100 meters). Cat5e cables feature improved structure to reduce crosstalk and system noise for long-distance use.

An Ethernet cable usually contains eight wires connected by RJ45 connectors on either end, each featuring an 8-pin, 8-conductor connector containing copper on one side and plastic clips with plastic clips on both ends to secure and make ready for use. Crimped ends secure the wires further.

Assembling an Ethernet cable begins by making sure that the copper sides of each pair face upward. Next, following our color-coded guide above, connect one end of your cable to an RJ45 port on your network router or switch and another end to either an RJ45 jack on a security camera or PoE injector.

Plug-and-play cameras have pre-made cables with these connectors already attached, making installation fast and straightforward for users of any skill level. However, due to not being shielded, they may increase electromagnetic interference risks.

To ensure the RJ45 connections are correctly made, consider investing in a cable tester. You can purchase this tool online or from home improvement stores to verify that twisted pairs are connected correctly before crimping and testing it to install your IP cameras confidently.
