How to Cable CCTV for Your Home or Business-Learn the basics of running security camera wiring. Find out what tools you need and the steps involved.


Before you can install a CCTV system, it’s important to plan and map out the entire project. First, you need to identify the areas that need monitoring and the types of CCTV Camera Attachs that will be used. Then, you’ll need to calculate the number of cameras required, the type of cabling that will be needed, and the distances between each CCTV Camera Attach and the recording device. After you’ve planned the entire project, you can now begin the installation process.

Determine the number of cameras needed

Before you can plan a CCTV system, you need to determine the number of cameras that are necessary for coverage. Consider what your primary goals are for the system; security from theft, observation of people and processes, or only recording evidence if a crime is committed. Knowing how many cameras will be needed will help you plan your budget and ensure that all areas are covered adequately.

Firstly, determine what type of CCTV platform you need: Analog or IP Cameras. Analogue cameras use traditional coaxial cables to record to a dedicated Digital Video Recorder (DVR). Digital IP cameras use an internet-based platform to connect each camera and stream redundant video data back to your Network Video Recorder (NVR).

Once you have decided on which type of camera you require, measure the area where it needs to be installed. Establish viewing distances the camera has to cover and then mount it in the appropriate position. Then count up how many total cameras will be necessary for complete coverage based on this initial assessment. Ensure that all vulnerable access points have adequate coverage and make sure no blind spots exist within your premises; increasing the coverage can mean adding more cameras or moving existing ones if necessary. Once these basic parameters are established, move onto planning camera placements in detail as well as considering any other surveillance equipment required such as hard drive space or extra memory modules for recording video footage on site.

Choose the camera locations

To effectively plan your security camera installation, you need to first decide where you’ll be placing the cameras. The number of cameras you use will depend largely on the size of your property or coverage area, and where key areas are located. You may have already identified these areas when doing your risk assessment.

For example, a single 4-camera system might cover a corner entry/exit point, a parking area and adjacent alleys; while an 8-camera system would work well in a parking lot or extended perimeter. Place all of the cameras so they have the widest possible field of vision, allowing for overlaps and eliminating any potential blind spots. This will also enable you to determine the necessary cabling run length with greater accuracy.

In order to optimize coverage area and even out each camera’s viewing angle across multiple elevations, adjust each camera for pitch and/or yaw wherever possible – this way only pan-tilt-zoom (PTZ) cameras will be needed for larger coverage jobs. After selecting the optimal locations for your security cameras, make sure that each one is firmly in place with appropriate mountings (e.g., wall mount versus corner mount).

Choose the type of camera

When it comes to selecting the type of camera for use in your CCTV system, there are a few considerations to take into account. The type of camera you choose will determine how much wiring and power is needed, as well as the lenses used for focusing and zooming.

IP cameras are digital cameras that use high-quality video streams over an IP network. They require less wiring than traditional CCTV cameras but can be more expensive due to their higher resolution capabilities. These cameras are most commonly used in highly secure locations where people or events must be monitored closely.

Analog cameras use video signals transmitted over coaxial cables. While using less modern technology, they cost significantly less than IP cameras while typically offering similar image quality if a good analog-based system is bought and installed correctly.

Finally, dome/PTZ cameras provide full range panning and zooming functionality as well as often being configurable remotely via software controls. Dome/PTZ cameras tend to be the most expensive option but they offer the widest range of options when it comes to covering large areas or altering focus throughout a shift at a place like an airport or soccer stadium.


Installing CCTV is a great way to keep your home or business secure from intruders. But before you can get started, you will need to set up the cables and configure the system. In this section, we will go over the steps for properly installing CCTV for your home or business. This includes running the Cable Measure, connecting them to the system, and ensuring that the CCTV is properly powered. With these steps, you can ensure that your CCTV system is properly installed and ready to provide you with the security you need.

Mount the cameras

Once you have your CCTV cameras, it’s time to install them. All of the cables that run between the cameras and the recorder must be laid out and secured before mounting any cameras. Begin by running power, audio and video cables from each camera to the recorder using the appropriate supplies for each. These can include security boxes, ducts or conduits, which are available in various sizes depending on whether you are running through walls or fences. Depending on the type of camera you have chosen, make sure you are running either RG59 coaxial cable (for most analog cameras) or CAT5e/6 twisted pair cable (for most IP cameras) from each camera to the recorder’s ports.

Once you have all your cables laid out and secured in place, it’s time to mount each camera in its desired location. Securely mount your camera near any area of interest such as entrances at a business or an adjacent wall in an alleyway for additional security protection for your home or property. Make sure there is a direct line of sight between where you want to record video footage and the location of each camera. Make sure that your CCTV installation provides full coverage throughout your property including parking lots and alleyways by properly securing mounting brackets at strategic heights around possible entry points into properties and spaces where surveillance is needed most urgently.

Connect the cameras to the DVR

Connect the cameras to the DVR using cables appropriate for your CCTV system, such as coaxial or Cat-5/Ethernet cable. Make sure that the cables are long enough to reach from all of your cameras – including hidden cameras, if necessary – and back to the DVR. Most cameras will have a power source near them that allows you to power the camera through a standard AC adapter. Connect each camera’s video output cable, power cable (if applicable) and audio output cable, if applicable, to an input on the DVR. Note that some systems may require additional steps (such as programming security codes) before they will detect and display video output from all connected cameras. Refer to your system’s installation instructions for exact details on connecting your cameras.

Run the cables from the cameras to the DVR

Once the cameras are installed, you must run the cables from each camera to the Digital Video Recorder (DVR). This is an important step and needs to be done carefully. Start at each camera and run a coax cable from one or more cameras and thread it through the walls, up into the attic, or down into the basement if necessary. You will want to avoid any places that may have excessive moisture or dampness. Once it reaches a point near the DVR, you can run surge protectors as needed.

You may also need to use drilling tools and other supplies to mount conduit boxes along structural elements such as walls and ceilings so that your wires have protection from damages like breaking or tearing while in transit. When possible, use holes already present in walls so that you can retain the structural integrity of your property without having to take risks by adding new ones. The mounting of conduit boxes must be done with precision using techniques like power drills with slow speeds and flat bits, hand drills which are able to reach difficult corners of your room’s architecture, ordinary wood screws with anchor points for neat attachments of cables for optimum protection against environmental hazards such as rain or snow among other weather dangers.

Having completed running your cables from each camera up until its connection point at your DVR unit, make sure you label them correctly according to their placements within your home or business premises for quick identification repeat usage when need arises for repair purposes incase of damaged cable lines

Configuring the DVR

Before you can begin using your CCTV system, you must first configure the DVR (Digital Video Recorder) to receive images from the security cameras. Depending on your system, this can be a fairly straightforward process, or a bit more complex. Before getting started, it’s important to understand the basic steps of configuring a DVR for a CCTV system. Let’s dive into the details.

Connect the DVR to a monitor

Once you have the cables set up and verified, the next step is to connect your DVR to a monitor or TV. Connect one end of the HDMI, VGA or Composite cable to the corresponding port on your DVR and connect the other end to the display device.

You will then need to use either a USB mouse or an external remote control that is included with many DVRs. This allows you to navigate through the menus on your monitor and configure settings for your system. When you are finished, be sure to save all changes before powering off your system.

You may also need to adjust your display settings for optimal performance. On most DVRs this can be done using the auto-adjustment feature located in its on-screen menu options. It is important that you adjust these settings prior to viewing footage on any monitors connected directly to a Digital Video Recorder (DVR).

Connect the DVR to the internet

There are several ways to connect a Digital Video Recorder (DVR) system to the internet. The most popular method is to connect the DVR directly with an Ethernet cable. This allows for a secure, uninterrupted connection and superior performance. This method requires an active network connection, as well as valid TCP/IP settings and ports opened on the router or modem that is connected to the network.

A second option is connecting through a Wi-Fi connection if one is available in your area. This provides peace of mind, as no physical wires are needed to link the device to your internet source. Depending on your location and distance from the router or access point, however, you may experience spotty service or slowdowns during peak times when multiple devices are connected on your local network.

The third option is connecting via a 4G/5G cellular modem or dongle that can be plugged into either the DVR itself or directly into a compatible router or modem. This solution offers stability and reliability even in rural areas with little-to-no Wi-Fi coverage, but it involves paying an additional provider bill each month for cellular service.

No matter which option you choose, keep in mind that you should always use high-quality cables and connectors, as well as configure security settings according to current industry standards (such as WPA2). Do not forget also to periodically change passwords for additional security measures.


Testing is an important part of any CCTV installation. It is important to make sure that the system is working properly and that all the cables have been connected correctly. In this section, we will cover the process of testing your CCTV installation. This includes testing the cables, the video and audio signals, as well as the power supply.

Test the cameras for video quality

Once the cameras are installed, it is important to test for video quality. To do this, connect the cameras to a monitor or DVR and adjust the settings such as brightness, contrast, and focus. Though most security systems come with auto-focus capability, manual adjusting may be necessary for optimal performance. Additionally, check for any sign of interference from other nearby devices that may impact video quality. Take this time to determine which cameras should receive night vision capabilities and ensure that these can also be manually adjusted for optimal results.
If you require optional features such as motion detection or facial recognition software, these should also be tested at this stage in your installation process.It is extremely important to make sure your system is compatible and properly configured with any add-ons before continuing onto the next stage of installation. The data collected by your security camera will only benefit you if you have taken steps to ensure complete accuracy throughout its setup process. Once finished with calibration and configuration testing, your cable CCTV system should be ready to protect your home or business!

Test the recording capability

Before putting your CCTV surveillance system into use, you should test to make sure it is properly recording. This can be done two ways: by setting up the DVR to record footage and playing it back, or by using a CCTV test monitor.

To use the DVR recording method, enable recording in the settings menu of your surveillance system software. Select the date and time that you’d like to start recording from (you can pause and resume the recording if needed). Once compilation is complete, review the footage for any skips or other disruptions in quality. If everything looks good from this playback, you have passed this portion of testing.

A separate CCTV test monitor can be used for testing in order to ensure that each camera is properly connected and transmitting pictures with clarity. The CCTV tester should display a four-way picture split (with four cameras displayed on one screen) when connected successfully. Check each frame for detail and lighting accuracy before confirming that your CCTV surveillance system is working correctly.


CCTV systems require regular maintenance in order to keep functioning properly. This includes regular cleaning of the lenses and the camera body, as well as checking the cable connections and signal strength. Routine maintenance of CCTV systems is essential to ensure that they are always working correctly and providing a high-quality image. In this section, we will discuss how to best maintain your CCTV system.

Regularly monitor the system

It is important to regularly monitor the system to make sure it is operating optimally. This can be done by checking for gaps or blind spots in coverage. Check the image quality of all monitored areas to ensure the cameras are generating sufficient detail that can be used for possible identification purposes. Furthermore, review your installation plan and adjust as necessary if there are any elements that need to be changed or added over time. Ongoing maintenance can help you identify discrepancies and ensure your CCTV system is delivering maximum security coverage at all times.

Lastly, check regularly for any network or other software issues that may impede your surveillance footage from being captured and stored correctly on local storage devices or on the cloud. Make sure your recording devices have ample space for footage retention, as older recordings should be removed to avoid overwhelming storage capabilities. Regular maintenance keeps you up-to-date with the performance of your CCTV setup, allowing you to make adjustments if necessary while still providing reliable security coverage

Check the cables for any signs of damage

It is important to check the cables regularly to make sure they are not broken, worn or loose. Make sure all the connections, cables and wires are firmly connected and free from damage. If there are any signs of damage, such as frayed or broken wires, replace them with quality ones. Check for bent plugs and corrosion on any copper coated wires. Identify and label any unused cables so that they can be easily identified in case of future repairs or upgrades. Replace all removable plates that cover connections with new ones, as the old ones may become brittle due to weather exposure over time. Also check for any signs of liquid or water damage near connections. If necessary, use a contact cleaner spray on exposed metal parts which will help remove dirt and dust particles that may cause faulty connections, ensuring reliable transmission in your CCTV systems.
