Many people don’t know how to extend their CCTV cable. Here’s a quick and easy guide on how to do it.
Extending a CCTV cable is not as simple as connecting two cables together. Depending on the type of cable you have, there are certain steps that must be taken in order to ensure optimal performance of your CCTV system and prevent signal loss. This guide will provide detailed instructions on how to properly extend a CCTV cable in order to maintain its performance and ensure your security system runs seamlessly.
It is important to first identify the type of cable you will be extending. Common types of cables include Siamese cabling, Ethernet cabling and twisted pair cabling. Depending on the type of wiring you have, there may be some extra steps that need to be taken, such as crimping or soldering components before you can connect your cables. Additionally, it is important to consider the length of the extension – long extensions may need an amplifier in order to maintain signal strength.
Follow these instructions carefully and use best practices when extending your CCTV cable for a successful installation!
Gather the Necessary Materials
Extending a CCTV cable requires that you gather the necessary materials needed for the job. This includes the CCTV cable, connectors, cutting tool, and a screwdriver. Depending on the type of cable, you may also need a crimping tool. Make sure you have all the materials and tools needed before you begin.
Extending a CCTV cable can be a cost-effective, simple alternative to costly camera installations. To get started on your project, it’s important to gather all of the materials you need.
First, select the type of CCTV cable that you require for the job. The three main types are Siamese cables, RG59s and Cat5s. Siamese cables come with a power connection as well as video connections and can handle multiple cameras if needed, while RG59 and Cat5 cables are solely used for video signals. All three will require BNC connectors once they have been cut and joined later on during installation.
Next, purchase enough cabling to cover your needs – which you can measure out prior to purchasing by using chalk lines or colored tape – along with some additional cabling in case of mistakes or additional adjustments during installation. Peripheral components such as CCTV camera power adaptors may also be needed depending on your set-up.
Before purchasing any items, make sure to read over any special requirements related to the product manufacturer in order to ensure compatibility of your equipment for optimal performance. Once you have all of the necessary materials gathered and have a clear idea of how your system will be arranged, it’s time for installation!
In order to extend your CCTV cable and get the most out of your system, you will need to make use of connectors. Connectors are specially-designed metal pieces used to join two lengths together.
The type of metal connectors you will need depends on the type and size of the cable being connected. For most CCTV systems, that means an RJ45 plug or an F-type plug (sometimes referred to as an F-connector). RJ45 plugs are generally preferred for large installations while F-type plugs are appropriate for single or small runs. Both types of plug allow easy connection without soldering.
Along with connectors, tools such as a crimping tool, a coax cutter and wire strippers/cutters may be useful for making sure the job is done correctly with clean connections and minimal disruption. Ensure safety when using such tools by wearing safety goggles and gloves if necessary.
In order to make use of crimp connectors and securely extend your CCTV cable, you need to gather the necessary materials. The most important item is a crimping tool. This special tool allows you to properly compress the connector onto the CCTV cable so that it will remain secure for years. It is important to invest in a good quality, heavy-duty tool that can handle heavier gauge cables, as thinner cables are not as reliable or secure. Be sure to choose a crimping tool with multiple interchangeable tips so that you can customize it for different sizes and gauges of cable. Additionally, it should feature an adjustable tension spring that can be used to control the pressure applied while compressing the connector onto the cable. All these features will come together to ensure your extended cable remains secure and interference-free when put into service.
Before you begin the task of extending your CCTV cable, it’s important to gather the necessary tools and materials. A wire stripper is one of these tools and is essential for completing this job. You can purchase a wire stripper from most hardware stores, or you’ll find them in many electrical departments.
It’s important to choose a model that’s suitable for your particular job as there are many different types of wire strippers available. For most CCTV installations, a basic adjust-and-lock strip tool with small and large opening jaws should be adequate. This type of tool will allow you to strip both twisted pair and coaxial cables by locking it at the required cutting depth before securely gripping the cable.
To ensure the best results when changing or extending your CCTV cable, choose a good quality wire stripper that fits comfortably in your hand and has adjustable jaws that make firm contact with the cable when locking down the cutting blade. Additionally, look for features such as an ergonomic design, razor-sharp cutting blades and spring-loaded handles, which can make stripping cables easier (and safer!).
Prepare the Cable
Before you begin extending your CCTV cable, there are a few things you should take into account. First, make sure that you are working with the correct cable for your CCTV system. You should also measure the length of your existing cable to determine how much extra cable you will need. Finally, you should be sure to always use a grounding block for your own safety. With these points in mind, let’s get started.
Cut the Cable
Before you begin, it is important to ensure that the power to your CCTV surveillance system is turned off. Cutting the cable incorrectly may cause electrocution. For safety reasons and to prevent negative effects on your security system, it’s best to use an electrical tester to ensure that the cable is not live.
Once you have inhibited the power, you will need to cut the coaxial cable already running through your property in order to extend it and make room for a new connection point. When cutting your coaxial cable (RG-59), be sure to use a multi-tool or a pair of sharp scissors – never use nails or other hard implements that can nick and weaken the copper wire inside. To achieve a clean cut, check measurements before actually snipping away at the cable. Remove approximately one inch from each end of the cable that you want to join together, using careful precision and slice through in one quick motion; this will help avoid fraying or damaging any internal wires.
Strip the Wires
Once the appropriate-length camera cable has been chosen, it must be prepared for connection to the enclosure junction box. Carefully cut the cable to length and pull back 1″ of the outer jacket with a wire stripping tool. For most cables, this will reveal four internal cable wires coated in soft plastic insulation. If a ground wire is included in your run, there should be five wires in total. The primary function of these* colored correspondence wires is to connect the cameras power and video signals for viewing on a monitor or more recently stored digitally on an NVR recorder (Network Video Recorder).
Before any of this work is completed however, it’s essential you understand exactly which colored functions correspond with your CCTV system and its purpose before continuing with any wiring. The following secondary information details the four standard color codes common across all CCTV cabling types and systems:
-Red – This cable carries power from a camera’s AC adapter to the camera itself.
-Black – A second AC power wire occasionally found in long runs but not typically necessary.
-Yellow – This ‘video return’ wire serves as a connection between camera video signal and/or monitor or recording device input end as well as powering up cameras via direct current (DC voltage).
-White – An additional ‘video’ signal outlet throughout some plug & play BNC receivers can also be connected here through red/black/white wires instead of yellow/black complementing white pair used above due to different video standards output by their respective manufactures (e.g., RG59u vs RG6).
*Please be aware that other colored combinations may differ upon purchase depending on manufacturer choice at time of purchase.
Crimp the Connectors
For extending a CCTV cable, one of the tools that you may need is a crimper. This tool is able to make consistent connections with coaxial cable spark plugs that are used on both ends of the cable. To begin the extension, start by measuring out enough cable to reach the length needed for your application. Make sure to add in a few extra feet of cable in case you need more than what was initially measured out. Once you have the right length, begin using your crimper to attach spark plugs on either end of the coaxial cable.
Make sure to hold the connector with one hand and use your other hand to pull hard on each side of the wire so that it’s firmly inside its connector cavity before crimping them down. The crimper should also be held perpendicular to the base of its connector at roughly 45 degrees; this ensures that adequate pressure is applied evenly on both sides when making your connection. Once these steps are taken, it’s time for testing before completing the extension process. Using an ohmmeter, check for continuity between each connected contact point and headers; any loose or incorrect connections should be corrected immediately before further use. With these simple tips and an understanding of how a coaxial cable connection works, it’s simple enough to extend any CCTV cables with ease!
Connect the Cable
Extending your CCTV cable is a straightforward process that requires basic technical knowledge and tools. To begin, Attach the connector of the cable to the camera and the recording device. Depending on the type of cable you’re using, you’ll need either an ethernet cable or a coaxial cable. Make sure to secure the connection tightly so that it won’t be disrupted. In this section, we’ll take a closer look at the different steps involved in attaching the connector.
Connect the Connectors
Once you have your cable pulled through the conduit and have identified its ends, you need to prepare the connectors. It is easier if you strip the outer sheath of the cable first before connecting it to the connectors. Start by measuring out a sufficient amount of sheath – usually around 8 mm – then cut it off. You should then peel or scrape away any insulation and til you reach 4 pairs of wires.
Using crimp terminals or screw terminals attach them to either end of your cable (if one end already has a connector fixed). Then, cut the ends off any excess strands. For crimp terminals, twist each pair with a pair of pliers where possible and place in terminal cavities from left to right (top row: blue/white, brown/white; bottom row: blue-brown). Once complete use pliers to compress by squeezing handle firmly at both sides until only 3mm is exposed on either side.
For screw terminals, make sure the stripped wires are reaching their respective connection points on either side, (top row: white/negatives – blue/positives). Once connected use an appropriate screwdriver to tighten until secure. If using an electrical box for extension make sure two screws are provided for cloth-insulation for each wire and that it is cleanly folded away before insertion into box wall.
Needless to say that all connections should be checked twice before connecting any powered device/apparatus!
Test the Connection
Before connecting the cables, it is important to test the connection first to ensure that everything is working properly. To do this, simply unplug the power on both ends of the cables and then connect one end of the cable onto a receiver unit and plug in the power. Move one metre away from your receiver and plug in another cable into a tester unit. This tester should show that there is power being sent through the cables. If it does, then you are ready to begin extending your CCTV video cables.
Secure the Cable
When it comes to extending CCTV cables, it’s important to secure the cables properly and make sure they are secure from damp, weather, vibrations and rodents. Begin by inserting the exposed end of the cable into the compression tool which you will use to attach the connection caps. Push down on the handle of your compression tool until it clicks; this compresses the hexagon-shaped cap onto the cable creating a watertight seal. Make sure that you secure all exposed cables with Cable Ties or Grommets to protect them from rodents, vibrations and dampness. After all cables are secured, use Flexible Conduit or PVC pipe over long runs of cable; this will ensure further protection against moisture and other external elements that could damage your cable.
When it comes to extending your CCTV cable, there are a few different options you can choose. If you’re looking for a more permanent solution, consider running a new cable from your DVR to the camera for connection, or installing CAT5/CAT6 wiring throughout your home. This can be time consuming and expensive, but it’s usually the most reliable method.
If you don’t want to run or install new cabling, you can extend your existing cables using a coaxial coupler sleeve or with an RJ45 Ethernet extension kit. Both of these options require careful mapping and configuration in order for them to work properly, so consider hiring professionals for this job. Finally, when extending cables and cords outdoors remember that surge protectors may also be necessary in order to protect against power surges that could damage sensitive equipment.
No matter what option you choose when extending cables and cords for CCTV surveillance systems, proper installation is key. With careful planning and the right tools, anyone should be able to easily extend their CCTV cable with minimal effort and expense.
