What You Need

When it comes to installing a CCTV camera with an NVR, there are quite a few things that you need to have in order to do the job correctly. You’ll need an NVR, IP cameras, network cables, power supplies, mounting brackets, and necessary tools. Depending on the installation, you may also need a router and a switch. In this section, we will discuss all the components and tools you need for the installation.

CCTV Camera

When installing a CCTV camera with a Network Video Recorder (NVR), you need to have the right equipment to ensure success. This guide will provide you with an overview of the essential components of a CCTV system, as well as the key considerations when choosing and installing a CCTV camera with an NVR.

CCTV camera: The primary component of any CCTV system is the video surveillance cameras. They need to be strong and durable, as they will be exposed to outdoor elements and may alternatively be situated in enclosed indoor areas. When selecting your cameras, consider factors such as maximum resolution, weatherproofing capabilities, day/night mode, PTZ control features and motion-detection settings. It’s also important to choose a camera that has the necessary LED lighting for nighttime visibility.

Network Video Recorder (NVR): A Network Video Recorder (NVR) is typically used in conjunction with an existing CCTV system to store and manage captured footage. It is possible for both digital and analog systems to be connected to a single NVR, which allows users to monitor multiple locations from one central location or remotely from another device if required. The NVR stores all captured footage under its own internal memory or dedicated hard drive – whichever option is best suited for your needs should be considered when investing in an NVR system.

Cables: One of the key components of any CCTV system installation is the cabling infrastructure connecting it all together. Different types of cables are used depending on installation requirements – RG59 coaxial cable is typically used between cameras and NVRs; twisted pairs are ideal for interconnecting multiple locations; LAN cables are required where there are network connections; plus power options including 16/2 gauge thermostat wire or AC power adapters depending on where you plan on using your cameras!

Connectors: Connectors are also critical components that ensure reliable connections between every part of your security system setup – quality connectors are designed specifically for use in harsh environments where high-vibration levels may occur over time, while other connectors such as barrel connectors allow easy wiring connections between devices around the installation area. You’ll need different connector types depending on what kind of cabling option you decide upon during your installation process – some good examples include butt splice connectors or RJ45 crimp-on connectors.

Network Video Recorder (NVR)

A Network Video Recorder (NVR) is an essential component of a CCTV system. It is responsible for processing and transmitting video signals, recording video, and allowing the user to control, configure and monitor the camera system in real-time. An NVR is usually connected to an Ethernet network or a PoE switch, making it easy to view footage from remote locations.

In order to install a CCTV camera with an NVR, the first step is to choose your camera type. Different cameras are designed for different environments and applications – some are designed for outdoor use while others can be used indoors. Choose your cameras based on the image quality you want, resolution requirements and budget.

The next step is to locate the area where the cameras need to be installed. Make sure that there is enough light available at all times in order for clear images day and night. Choose a dry location in which there will be no interference from any objects or other electronics nearby.

After that, you will need to connect the camera directly into your existing network by using an Ethernet cable or by setting up a Power over Ethernet (PoE) injector/splitter if you’re using IP cameras with PoE support. Once that’s done, plug in your NVR and then connect it directly into power supply unit as well as into router via provided Ethernet cable. You should then set up your cameras via given web interface or software depending on the type of NVR you have chosen and follow instructions carefully for complete setup process completion including adding users with required permissions levels etc., applying any desired motion recording settings before finally making necessary connections between NVR’s RCA / HDMI output ports into audio/visual input(s) on any desired monitor/TV.. After these steps are taken care of your CCTV system can start live streaming video footage across its entire installed perimeter!

Power Supply

Setting up a CCTV camera system with an NVR requires a power supply in order to operate the cameras and NVR. Most commercial security cameras come with an individual power adapter, while some may come with a standard PoE (Power Over Ethernet) cable connector. Both types of power connectors will require access to an electrical outlet in close proximity to the camera’s installation point.

For the most part, each camera’s power source will be set at a specific voltage. This is typically 12VDC, 24VAC, or 48VAC and it should match the required input of the power injector or PoE switch. For example, if you are using a PoE switch for your CCTV setup then it must offer an output voltage that is compatible with your security cameras. The same applies for any additional accessories such as lighting fixtures or network connections.

It’s important to keep in mind that any device that is connected to an NVR system needs to be on its own circuit so as not to interfere with other electronic devices in the home or business setting. If multiple cameras are installed on one circuit then it can cause electrical overloads and resultant damages due to excessive heat or fire hazards from overloaded circuits.
For maximum safety and ease of use it is advised to work with a certified electrician who can provide guidance on proper wiring techniques when installing your CCTV system’s network cabling layout and power supply connection points.

Ethernet Cable

The next step if installing a CCTV camera with an NVR is to get an Ethernet cable. Ethernet cables are essential for connecting your NVR to your network and allowing it to have access to the Internet. You may also need one or more Ethernet cables for routing data from the cameras to the NVR. The specifications of the cable depend on the distance between your router and NVR, so be sure to buy the right type and length for your system.

When choosing an Ethernet cable for your CCTV system, make sure it meets with IEEE 802.3 standards, which guarantee reliable speed and performance over long runs of wire. Cables with Cat5 or Cat6 ratings provide faster speeds than earlier versions, making them ideal for transferring large amounts of data quickly while reducing interference. For short runs (up to 100 ft.), Cat5e will be sufficient but longer runs may require a more robust Cat6 cable. Choose a shielded twisted pair (STP) cable if you want extra protection from electromagnetic signals that could interfere with the data transfer rates in more industrial applications.


Once you have selected the correct NVR and CCTV camera, it’s time to gather the supplies you need for installation. A monitor is necessary to view the live footage from your system. Choose a monitor that is suitable for the NVR being used. Most systems require an HDMI or VGA input and can be connected via USB. Inputs will vary depending on the type of NVR used, so be sure to check compatibility before purchase. The monitor must be able to connect with the NVR in order to stream live video footage or access saved recordings. When security cameras are connected directly to a computer, they are usually viewed using software which must be installed on the computer in question. If you intend on doing this, ensure that your surveillance system has compatible software available before buying a monitor for this purpose.

Installation Steps

Installing a CCTV camera with an NVR can be a relatively straightforward process. First, you will need to decide on the placement of the camera, followed by connecting the camera to the NVR. Next, you need to power the NVR and camera and connect it to the internet. Finally, configure the NVR and the camera settings . In this section, we’ll go through all of these steps in order to help you successfully install a CCTV camera with an NVR.

Connect NVR to Monitor

Once you have powered on your NVR, it is time to connect it to a monitor or TV for viewing. This is an important task as having a visual display for playback, live view and setting the system up is essential.

Connecting the NVR to the monitor can be done with either an HDMI cable or an RCA video display cable. Make sure you are plugging into the video output port of the NVR and if you are using more than one camera for recording, make sure that multi-splicing of wires does not occur during installation.

Once connected, power on the monitor and select HDMI or AV mode via its remote control so that it displays signal from the NVR correctly. To select between channels, use fast-forward or rewind keys located at control panel of your NVR or remote by pressing CH+/- keys until desired channel appears on the monitor’s screen. Now you can check whether recordings are functioning properly by playback functions and make necessary changes in either settings with help of simple on-screen navigations provided by respective device companies.

Connect Power Supply to NVR

Connecting the power supply to the NVR is an important step when installing a CCTV camera system with an NVR. First, plug the supplied DC power adaptor directly into one of the power ports located at the back of the NVR. Make sure that it is firmly seated and locked in place.

Once connected, plug the other end of power cable into a power outlet. Ensure that you use a socket rated for 12V DC current and with enough capacity to support your camera system. Make sure all wiring is securely fastened and will not become disconnected.

Next, connect your included PoE switch to your NVR using an Ethernet cable. If you do not have a PoE switch, please refer to our guide on configuring advanced settings for more information on using Wi-Fi connection instead of Ethernet wiring to establish connection between devices within your surveillance network.

Connect Camera to NVR

When installing a CCTV system, it is important to connect the camera to the network video recorder (NVR). To do this, start by powering off the NVR and camera. Next, you need to connect an Ethernet cable between the camera and NVR ports. The exact ports might be different for different cameras and NVRs, but a standard Ethernet (CAT5 or CAT6) will always work well.

It is also important that you ensure the correct power supply is used for both components. Choose a compatible power adapter for your camera; usually it will be hardwired or need a DC power plug to provide power for video signals and movement detection. For most NVRs, an AC input is required but some might also support DC input from a separate adapter or battery.

Once the cable and powered are connected correctly, switch on both devices again. The NVR should detect new cameras and prompt users with relevant displays once all components are set up properly. Depending on your device settings and setup parameters, it may take several minutes before all recordings become visible in the live feed displayed on your connected display monitor/TV screen. If successful, adjust with various camera angles using the joystick normally supplied with most CCTV packages until satisfied with results.

Connect Camera to Power Supply

In order to connect the camera to a power supply, an AC adaptor needs to be connected to the camera. First, locate the power port located on the rear of the camera and plug in the provided power cord. Then plug one end of the power cord into an available wall socket or power outlet. Use caution when handling electricity and make sure that any wall sockets being utilized have output ratings similar to that of the AC adaptor’s parameters.

Once its plugged in properly, a light indicator on both ends will turn on indicating a successful connection between them. Finally, if running on a battery backup system instead of using mains power, it is necessary that batteries be installed in both the camera and NVR in order for them to function correctly during any power outages.

Connect NVR to Network

After the NVR and cameras have been physically connected, the network connection must be established. The first step is to make sure that the NVR is connected to the same local network as the router. This can be done either with a wired connection or wirelessly, depending on your setup. Once it is connected, launch an internet browser and then enter either or in the address bar to open the router’s settings page.

Look for a section labeled “Network” or “Local Network” and under this you should see two settings labeled Wireless Network Name (SSID) and Wireless Password (Security Key). Take note of both of these settings as they will be used later to link up your NVR system to your router’s WI-FI network.

Once you have noted down this information, go back to your NVR system’s menu and look for a setting labeled “Network” or “Wi-Fi” – and click on this option. A list of available WI-FI networks will appear in the menu – choose your home network from this list and enter in both the SSID and Security Key into their respective fields when prompted by entering them earlier from your router’s settings page Visit UTP Surveillance Store Now – https://utpsurveillancestore .com/. Click “OK” to confirm your selection and complete the setup process – you’ll now be able to access live video streams from all of your cameras remotely via any device connected to that same Wi-Fi network!

Configuring the Settings

After setting up your CCTV camera and NVR, the next step is to configure the settings. This involves setting up the video recording quality, video resolution and frame rate, as well as the alert and alarm settings. It’s important to properly configure the camera and NVR settings for maximum performance and protection. We will take a look at how to configure the settings for a CCTV camera and NVR.

Access the NVR’s Web Interface

To access the NVR’s web interface, plug a monitor into the NVR, then connect a mouse and keyboard to the NVR. Use the mouse and keyboard to navigate through menus in the NVR’s interface. The web interface offers several options for modifying or setting up the CCTV system.

For example, once you have accessed the NVR’s web interface, you can configure several settings or perform camera setup operations. Some of these tasks can be completed using just your internet browser, such as configuring day/night mode settings or enabling motion detection recording.

Other tasks will require downloading additional applications from your network provider’s website and installing special software on your computer before they can be completed (e.g., setting up PTZ cameras). Additionally, be sure to review all of your camera’s features so you know which functions and settings are available to you with your particular CCTV system model. Once these configurations are complete and verified, you should have successfully installed your CCTV system with an NVR!

Add Camera to NVR

To add a camera to an NVR (Network Video Recorder) system, you need to follow the steps outlined below. These instructions are based on a generic NVR and cameras. If you have a specific make and model, please refer to the product manual for detailed instructions.

1. Connect the camera to the power outlet and adjust the angle of view as per your requirements. Check that all settings of the camera match those in the settings menu.
2. Plug in one end of an Ethernet cable into the port at the back of your camera, and plug the other end into an available port on your NVR (Network Video Recorder).
3. Navigate through your NVR’s menu until you reach “dev_manage” option that should help you add IP cameras compatible with it ,by default this option is generally available under “Setting”Menu of NVRs setup page via PC or mobile phone apps/ browser console .
4. Enter either a static or a dynamic IP address for each cameras at their appropriate fields within device management section.. As per best practices, it is recommended that static IP addresses be used to configure network devices such as surveillance cameras where possible thereby alleviating any potential conflicts caused by DHCP assignment of dynamic IP addresses which are often temporary in nature while making them easier to remember and access via Alexa/ Siri etc.. This allows end user greater control over network topology .
5.Once necessary connection details have been entered for each device/camera at their respective fields/details in Dev_manage section , select “Ok” button present near bottom right side corner for confirmation which will probe for any configured devices connected to its vicinity(within same segment) over local area networks and confirm results by displaying their assigned hardware state within same window pane .
6 Once confirmed ,configure other necessary settings like motion detection recording type password resetting etc… using compatible browser console /mobile apps then click apply it shall start configuring rest of unified devices further saving this entire setup & its related configuration parameters along with corresponding security keys & passwords if any were set during process upfront thus wrapping up entire process successfully ..

Configure Camera Settings

The camera settings must be adjusted in order to ensure optimal performance when installing an NVR CCTV system. This includes things such as setting the correct resolution, frame rate, bitrate as well as other important parameters such as exposure compensation, white balance and backlight compensation. All of these settings are usually set on a menu accessed by double clicking the selected camera in the NVR’s interface. It is important to note that all cameras must be individually adjusted so it’s often a good idea to first label each camera with a small sticker before connecting it to the NVR.

Resolution: Selecting the appropriate resolution is paramount for good image quality and efficient storage space allocation. This is especially true when selecting different resolutions across multiple cameras or when increasing total system storage by recording at a higher resolution than initially planned.

Frame Rate: Frame rate determines how many frames per second (fps) will be sent from each camera. Generally speaking, higher frame rates result in smoother playback but also require greater resources and thus have an unfavorable impact on storage capacity. It’s generally best to keep this parameter at no greater than 30fps unless absolutely necessary

Bitrate: Bitrate defines how much data each second of video requires for compression/transmission from each camera – measured in kilobits per second (Kb). Typically speaking bitrates of 500Kb/second up are considered suitable for standard image quality depending on factors such as scene complexity and motion levels, however; this parameter should always be tested to ensure optimum performance when adjusting settings for all cameras connected to the NVR system before activation.

Configure Recording Settings

Recording settings allow you to specify when video should be recorded and for how long. Many different recording settings may be available depending on the capabilities of your CCTV system, however the most common ones are motion detection, manually triggered, and scheduled recording.

Motion detection: This setting tells your camera to start recording when motion is detected in the field of view. It’s useful for areas with a lot of traffic or movement at certain times of day as it will save hard drive space by only recording pertinent footage.
Manually triggered: If a manual trigger is active, you can set it up so that if someone presses the button in your NVR’s user interface, it will cause all cameras in that system to go into record mode, regardless of what detection setting they were previously configured with.
Scheduled recording: You can also configure cameras to go into record mode at specific times or intervals during the day/night using a timer setting. This is very useful when you need to ensure that footage will always be available during periods of activity like business operations.
When configuring motion detection settings ,there are a few basic options like sensitivity level (to determine how much movement needs to occur before triggering recording), area masking (to block out certain parts of the camera’s view from triggering detection), and object tracking (so only moving objects will activate the camera). Once these settings have been put into place, you can be confident that any important footage won’t be missed due to incorrect configuration on your camera’s part.

Test the System

Once you have completed the installation of your NVR system, it is essential to test the system for proper functioning. Start by connecting the NVR to a monitor and power it on. You can check all camera settings, including contrast, brightness, saturation, etc. to make sure they are set according to your preference. Additionally, you can change the display layout of each camera to optimize your security setup for a more holistic view of the monitored area. After making any changes and checking these settings, be sure to save them before moving on.

Next, check all functions within the NVR itself, such as recording settings, playback functions and notification setup which will alert you when there is an event detected by one or more cameras. You should also take this time to configure any third-party device or software integration as required with your system setup before testing live video streams from each connected camera within your network. Once all adjustments are made and tested properly then you will be ready to monitor and secure your property using your newly installed NVR systems.


Now that you know how to install a CCTV camera with an NVR, you will be able to customize the surveillance system for your needs. Be sure to carefully read any instructions that come with your camera or DVR before attempting any of the steps outlined above. If you need help, be sure to contact the manufacturer or other support services.

Once your CCTV security system is installed and operational, it is important to regularly maintain it. Regular maintenance will keep your cameras running well and help ensure their long-term reliability. Some common maintenance tasks include:
-Inspecting hardware for signs of damage
-Cleaning out dust or dirt particles from exposed circuits
-Verifying proper operation on a regular basis
-Updating firmware and drivers when available
-Replacing cameras that have reached their end of life span
-Conducting backups of recordings
Note: Depending on what equipment you have chosen for your Security System, additional maintenance steps may apply; please review the individual product documentation from the manufacturer for further information.
