In this blog post, we’ll show you how to wire CCTV cameras for your home or business.


Before you start wiring your CCTV cameras, it’s important to plan the network carefully. Gather Necessary Equipment such as the type of cameras, the area to be monitored, the size of the wires, the location of the power source, as well as additional features such as recording and storage capability. All of these elements need to be taken into account to ensure that your CCTV system is set up correctly. Let’s look at the planning process in more detail.

Determine the type of CCTV system you need

When deciding on a CCTV system for your home or business, it is important to determine the type of system you need in order to ensure its success. To make the decision-making process easier and more efficient, it is important to check the power of the different options available and know what your specific needs are.

Types of CCTV Systems:
-IP-based Video Surveillance (IP Cameras): This type of surveillance requires an IP network connection and can be accessed remotely through the internet. Check the power of this system which offers the highest quality resolution and allows for remote access from anywhere in the world, making it ideal for businesses who need to monitor their premises from afar.
-Analog Video Surveillance (Analog Cameras): This type of system consists of traditional cameras that are connected directly to either a digital video recorder (DVR) or a multiplexer. They store analog data on videotapes or hard drives, providing enhanced storage capacity as well as picture resolution.
-Network Video Surveillance (Network Cameras): This digital video surveillance uses a standard network to transmit audio/video signals over short distances between multiple screens that are located far away from each other. It also permits remote monitoring with powerful encryption capabilities, allowing users to view live footage remotely in real time through an IP network connection.

These different types offer different levels of protection depending on your needs and budget. When deciding on which type is right for you, check the power of factors such as scalability, night vision, camera placement locations, adjustable resolutions and image enhancement; all these aspects add up when selecting a proper CCTV system for your home or business security needs.

Calculate the number of cameras and cables you need

When calculating the number of cameras and cables you will need for a CCTV installation project, several important factors must be taken into consideration. The most important factor to consider is the area size and layout of your property, as this will inform the coverage area and number of cameras that are required. You will also need to consider factors such as lighting conditions, level of detail needed from the footage and any additional equipment that might be necessary, such as motion sensors or infrared illuminators. In addition to calculating the number of cameras and cables you need, you should also create a written plan which outlines where each camera should be placed on your property for optimal coverage. It is also beneficial to make a list of all components needed before starting your installation. This list can include items such as power supply units, junction boxes, adapters, mounting hardware and video monitors or recorders.


Pre-installation is an essential step when it comes to wiring your CCTV system. The areas where you are going to mount your cameras and DVRs need to be determined in advance. The clearance you need for the wiring needs to be taken into account as well. It is also important to make sure the power outlets are easily accessible and that the cameras and DVRs are secure. Once all these considerations have been made, you can move on to the actual installation process.

Test the cameras and cables

Testing the cameras and cables is a crucial step in the installation of CCTV for your home or business. Before beginning installation, make sure that all cameras and cables are tested for performance. If a defect is found, it must be replaced before the system can be properly set up.

When testing cameras and cables, take the following steps:
1. Visually inspect each camera and cable before installation to ensure they are not damaged or defective in any way.
2. Connect each camera to the power adapter and into your recording device using an authorized BNC cable.
3. Ensure that all connections are secured tightly and that no signal is being blocked by anything in your field of view such as furniture or window curtains/blinds/panels to ensure maximum effectiveness of your surveillance system.
4. Using a test monitor, test video functions across each camera to verify they are operating properly with no fuzzy images or other anomalies present on screen during video playback or live view mode testing.
5. Check audio connection by confirming audio is present when talking into the mic attached to each camera (if applicable).
6. Verify that all connections between your DVR/NVR and cameras have power running through them by using a voltage tester pen on each end of the cable connection point(s).
7 .Check for any interference from external sources such as power lines or other electronic devices located nearby – if any interlacing signals are detected, move these items further away from your field of vision and check again for satisfactory results prior to completing final installation stages within software/hardware setup process for CCTV system set-up on site at customer’s home or business premises location(s).

Choose a suitable location for the cameras

When you are installing CCTV for your home or business, one of the most important factors is to determine the proper location for each of your cameras. The exact placement for each will depend on your needs and the equipment you are using, but there are a few general criteria that can help guide your decision:

– Choose an area with clear visibility and relatively low foot traffic. You want to make sure that your camera’s visibility is not obstructed by pedestrians or other surface obstructions.
– Consider any potential outdoor elements such as wind, rain and extreme temperatures when determining a location. Your camera should be protected from these conditions as much as possible to ensure reliable operation at all times.
– Think about access points to areas; it may require installation in a ceiling or other high point if surveillance of entry points is needed. If this is the case then special equipment may be required to access these hard-to-reach places safely and securely, so plan accordingly when budgeting out installation costs.
– Make sure that wires have suitable access routes and can be hidden away properly to deter intruders or vandalism. It’s important that all cables remain secure throughout their entire length in order to ensure uninterrupted footage at all times.

Choose the right type of cable for your system

When wiring CCTV cameras, it is important to select the right type of cable to ensure that your video quality is not compromised. In order to truly maximize image quality, you must use shielded coaxial cables that are properly terminated with a compression connector. While these cables can be expensive and difficult to install, they are a crucial component of achieving quality images.

The type of cable most commonly used for CCTV systems is RG59 coaxial cable. This cable features an additional shielding layer that helps protect the camera’s video signal from interference and “ghosting” (when multiple signals appear at once). Furthermore, if you need to run the cable long distances (usually over 500 feet) or if you need the highest quality resolution possible, then using solid-copper core RG6 (quad-shielded) type cable is recommended.

In terms of runs shorter than 500 feet, Siamese type cables (also known as premade ) are another viable option. These are made up of two individual cables piggybacking each other-one for power and one for video transmission-and can be found in various types, including RG59 and RG6 versions. The choice really depends on budget and feature requirements.


Installing a CCTV system is not a difficult job but it is important to make sure that everything is installed correctly. This article will talk about the basics of how to wire CCTV cameras for your home or business. We’ll discuss where to put cameras, how to run the wiring, and how to connect them to the system. We’ll also discuss the types of cable used and give some tips on how to test the system once it’s installed.

Connect the cameras to the DVR

Once you have the necessary components, the next step is to lay out the wiring in its intended formation. Make sure to plan for where you will transition from open-air wiring to cable within a wall or ceiling. This means that it is important to have both power and video (coax) run directly from each camera location to the DVR location without splices; video signals suffer degradation over distance, so it is essential that high-grade cabling and connectors be used for EACH camera connection.

Begin by running the pre-measured wire from each camera position directly back to the DVR. Installers will then place a BNC (bayonet Neill-Concelman) compression connector on each end of the cables connected to the cameras. The BNC connector is an industry standard used to make connections between coaxial cables and CCTV equipment such as cameras, monitors and digital video recorders (DVRs). When correctly installed, BNC connectors provide an enhanced level of protection against damage or interference caused by stress on signals created by intermittent contact problems.

Connect the DVR to the monitor

Connecting the DVR to the monitor is important for being able to view and navigate through footage. The DVR will come with a VGA port and up to three BNC ports. Use the provided cables to connect one side of the BNC port to the Camera Attach Assessing Your Home security system is an important step to ensure it’s properly set up. To do this, you’ll need to connect one end of a BNC cable to the DVR and the other side to the monitor or LCD panel with built-in speakers. It’s recommended to use Siamese cables for direct connection or two separate cables. Once connected, you can use a VGA cable for optimum viewing. If you want sound enabled on your security system, you may connect an RCA splitter directly or use a power amplifier instead. Alternatively, you can also use an HDMI connection – make sure it’s compatible with your hardware setup before purchasing HDMI cabling for this purpose. Assess Your Home security system thoroughly to ensure it’s working properly.

Connect the DVR to the internet

Connecting a DVR to the internet is an essential step in the installation of home or business CCTV systems. Having an internet connection will provide remote access, enabling you to view your CCTV footage from anywhere, as long as you’ve connected via WiFi or a wired connection.

To connect the DVR to the internet, you need to have a dynamic DNS service set up. This ensures that your device is always reachable with a static IP address that can be configured into your router’s DHCP settings. The rest of the setup will be specific to your particular router and and peripheral device being used in conjunction with the router. Depending on the type of router, such as 2G, 4G or 5G, you will have different setup options available.

Once the required parameters are determined, assemble whatever exterior antennae may be necessary for installation onto external ports on the router and attach any cables between components as per instructions included in either user guides or accompanying brochures available from DVR manufacturers and distributors. Many security equipment suppliers also offer detailed instructions for DIYers looking for additional guidance beyond what is provided by their initial purchase documentation. With some patience and precise attention to detail in completing these steps, consumers are often able to get their system up and running without needing outside professional help.


Now that the CCTV system has been installed and the wiring configuration has been completed, the next step is post-installation. This is the process of configuring the CCTV system, testing the cameras and the software, and making sure all components are working properly. This article will discuss some of the best practices for post-installation of a CCTV system.

Test the system to make sure it works properly

Once you have installed the CCTV system, you will need to test its functionality to make sure everything is working properly. Test each camera individually by allowing the camera to record a few seconds of footage. Then, play back the footage to verify that it was recorded properly and that there is no interference (noise or grainy qualities). Note: You should also test if the cameras are able to track movement from left to right and up and down effectively.

Next, test the video footage on multiple monitors/devices if applicable. Make sure that the video is being streamed properly, with no stops and starts or visual artifacts onscreen. Lastly, check for problems regarding compatibility: does your camera’s recording format match the compatible file formats that your storage device accepts? If not, this could create problems in future playback scenarios so you should ensure all video formats are compatible before proceeding.

Set up the recording and motion detection settings

The recording and motion detection settings on your CCTV system enable you to capture and store footage from your surveillance cameras. Recording settings vary by type of camera, but typically include time-lapse recordings or motion-activated recordings, which only activate when movement is detected within the camera’s field of view.

It is important to ensure that all recording settings are properly configured in order to get the most out of your system. For example, many cameras offer adjustable sensitivity levels for motion detection which allow for the elimination of false alarms caused by animals or other external sources. Additionally, many CCTV systems also feature digital video recorders (DVRs) with advanced control over recording settings such as event based triggers, looping playback options, time scheduling qualities and more. To take full advantage of these features, it is important to familiarize yourself with them and use them to accurately measure activity at home or in a business setting with a Cable Measure.

Set up the remote access features

Setting up the remote access features on your CCTV system will give you the freedom to view footage in real-time no matter where you are. To get the most out of your system, these steps should be taken:

1. Connect your DVR recorder to a router and port forwarding devices for remote access capabilities.
2. Determine a unique URL or IP address that will allow you to access your devices from anywhere in the world via mobile app, web browser, etc.
3. Configure camera settings such as resolution and frame rate. The higher settings will obviously provide more detail, but with greater expense in terms of memory storage and data transfer speeds on your network connection.
4. Install software that will enable remote viewing on all the necessary devices (cell phone, tablet or laptop) and enter the necessary credentials for logging in remotely to view recordings at any time without being physically present at base location with CCTV system installed.
5. Finally, do some test runs by connecting to all cameras remotely using camera-specific mobile apps, web browsers, etc.,to ensure all appropriate settings and hardware connections have been properly established before use of CCTV surveillance system begins.
