You may want to watch a CCTV (closed-circuit television) system installed in your house or business without buying a separate monitor. 

You might not have been aware that you can use your laptop’s screen as a monitor for your CCTV system. This helps you save money and makes it simple to monitor your property from the comfort of your laptop. 

How to Use Laptop Your Screen as a Monitor for a CCTV System

Equipment needed

  1. Laptop: A laptop is an essential piece of equipment for setting up a CCTV monitor. The laptop should feature an integrated display and the required input ports for attaching the CCTV system.
  2. CCTV Software: For your laptop to display the CCTV camera feed, CCTV software must first be installed on it. Usually, the maker of the CCTV camera provides this software. To know about CCTV cameras, please read my other article about how a CCTV camera works.
  3. Display Cable: VGA or HDMI cables are the most typical cables to link a laptop to a CCTV system. Video and audio signals are sent using HDMI, DisplayPort, and USB-C cables, whereas VGA can only deliver analog video signals without audio.
  4. USB Cable: A USB cable connection to a laptop is also possible with some CCTV systems. Typically, only video signals are transmitted through this type of connection.
  5. Power Supply: Power supply is necessary for CCTV cameras and DVRs (digital video recorders) to function. To prevent interruptions in the CCTV stream, ensure the cameras and DVR have a reliable power source.
  6. CCTV Cameras: You must have at least one CCTV camera to set up a CCTV system. Both single CCTV cameras and kits with numerous cameras and a DVR are available for purchase.
  7. DVR (Digital Video Recorder): A hard drive is where the DVR stores the CCTV footage that is captured by the cameras. You can also use a laptop or monitor to see the video.
  8. Audio Speakers: External speakers may need to be connected to the laptop if you also wish to enable audio monitoring. However, audio monitoring is not a feature found on all CCTV systems. And in many cases, laptop speakers usually do the job.
  9. Adapters or Converters: You might need to buy adapters or converters to make the connection depending on the input ports on your laptop and the CCTV system. For instance, if your laptop only has an HDMI connector, but your CCTV system only has a VGA port, you may require a VGA to HDMI converter.

Setting up the CCTV software

  1. Go to the “Support” or “Downloads” area of the CCTV camera manufacturer’s website.
  2. Look for CCTV software that works with your laptop’s Windows, Mac, Linux, etc., operating system. The software can also be found on the CD with the CCTV system.
  3. Save the software to the hard drive of your laptop after downloading it.
  4. Find the downloaded file and double-click it to launch the installation procedure after the download.
  5. Installing the CCTV software on your laptop is as simple as following the on-screen directions. You could be prompted to pick a language, accept the terms and conditions, and decide where to install the software.
  6. Launch the CCTV software on your laptop after the installation is finished.
  7. Before you can start watching the CCTV camera feed on your laptop, the software may ask you to configure a few options. The CCTV system’s IP address, the user name and password, and the camera settings are only a few examples of these settings.
  8. Enter the necessary information and save the adjustments.
  9. Thanks to the CCTV software, your laptop’s screen should now be able to see the camera stream.

Note: The manufacturer and software of the CCTV camera will impact all of the exact steps. Consult the user guide or support materials provided by the manufacturer if you run into any problems when installing the product, or get help from their customer support.

Connecting the CCTV system to the laptop

Your chosen technique will depend on the ports accessible on the CCTV system and your laptop. There are various ways to link a CCTV system to a laptop. The following are the most typical methods for attaching a CCTV system to a laptop:

Important! Do NOT connect the output from the DVR to the output of your laptop. This will result in permanent damage of either device.

  1. VGA: VGA was once the most popular method of connecting a CCTV system to a laptop. Most laptops and CCTV systems are compatible with VGA cables, which transfer analog video signals. Connect the VGA cable’s end to the CCTV system’s VGA output connector and the other end to your laptop’s VGA input port if it has one.
  2. HDMI: Another well-liked method of attaching a CCTV system to a laptop is using HDMI – HDMI connections. HDMI cables are typically used with more recent CCTV systems and laptops that enable HDMI connectivity. They transfer both high-definition video and audio signals. Attach one end of the HDMI cable to the HDMI output port on the CCTV system and the other end to the HDMI input port on your laptop to connect your laptop to your CCTV system via HDMI if your laptop has an HDMI input port.
  3. USB: Some CCTV systems let you use a USB cable to link to a laptop. It is less frequent than VGA or HDMI connections and typically sends video signals. Attach one end of the USB cable to the USB output port on the CCTV system and the other to the USB input port on your laptop to connect your laptop to your CCTV system using a USB connection.
  4. Wired Network Connection: You can connect to some CCTV systems with a laptop using a network connection, including Wi-Fi or Ethernet. The CCTV system and the laptop must be linked to the same network for this connection type to view CCTV footage remotely.
  5. Wireless Network: Some recent CCTV systems provide wireless connections to laptops via Bluetooth or Wi-Fi. The lack of cords makes this connection easy, but it may not be as dependable as wired connections and may involve more setup.

Note: Depending on the CCTV system and the technology in your laptop, the precise connectivity possibilities may change. Check the CCTV system’s compatibility with your laptop before buying it, and make sure the required ports and adapters are available.

Testing the setup

Following these procedures, you can check to see if your laptop is correctly displaying the CCTV system feed after connecting it to the system and configuring the settings:

Some Precautions:

There are several safety measures you should take while using your laptop as a CCTV monitor to maintain your privacy and prevent laptop damage:

  1. Privacy concerns: Ensure you are not breaching anyone’s privacy rights if you are using your laptop to watch over a location where others may be present. Ensure you are only keeping an eye on places where it is acceptable and lawful to do so, and refrain from keeping an eye on places where people could reasonably anticipate their privacy, including bathrooms or private living spaces.

This can happen if you continuously show the same image or video. Avoid leaving the CCTV software open when not in use for long periods, and think about using a screensaver or turning off the screen while the CCTV program is not in use.
  3. Cybersecurity: To lessen the danger of hacking or cyberattacks, use secure login credentials and keep your software and operating system updated. To further protect your network from illegal access and encrypt your internet connection, think about adopting a virtual private network (VPN).
  4. Electrical safety: Use the correct cables and connections to connect your laptop to the CCTV system to prevent electrical dangers. Before tweaking or modifying, follow the manufacturer’s instructions and unplug the cords from the laptop and the CCTV system.

Following these steps, you can protect your laptop from harm and ensure you’re using it sensibly and lawfully. Additionally, by using your laptop safely and securely, you may contribute to upholding the safety and privacy of the region being watched.
