How to Connect Cameras to Multiple Monitors

February 21, 2024

Mammoth Takeaways:

  • Setting up multiple monitors for your security footage is worth it if you have too many camera feeds to fit into a single screen.
  • A multi-monitor setup contributes to comprehensive CCTV camera surveillance in large spaces by providing adequate screen space to recognize valuable footage details.

Does your camera system produce more footage than can be effectively monitored on a single screen? If so, a multi-monitor setup may be exactly what you and your security team need.

Multi-monitor setups are especially useful for monitoring large spaces like warehouses, shopping centers, and corporate campuses (where placing every nook and cranny on a single screen is impractical).

Connecting your cameras to multiple monitors isn’t rocket science, but it does require a bit of know-how. That’s why we’re sharing the secrets of multi-screen setups with you today.

First, we’ll break down the benefits of multi-monitor setups, and then we’ll share expert tips that will help you connect cameras to multiple monitors yourself.

There are more than six million property crimes in the U.S. every year, according to the latest data from the FBI. That’s just one more reason to invest in a comprehensive security system.

Benefits of Multi-Monitor Setups

Guard watching surveillance from multiple cameras on multiple screens.

Situational Awareness

Multi-monitor setups allow security personnel to keep an eye on different areas at the same time, significantly enhancing situational awareness.


Multi-monitor setups allow for more efficient monitoring.

For example, one screen can display live feeds, another can review recorded footage, and a third might focus on live streams from high-risk areas. This division of labor means nothing slips through the cracks.

Screen Space

Using multiple monitors boosts security processes by providing ample screen space for CCTV footage details.

Using multiple monitors also enhances focus and removes the need to constantly switch between applications or video feeds when watching surveillance footage.

Improved Response Times

Multiple monitors enable security staff to spot and react to security breaches and other concerns quickly.

Understanding the Basics: What You Need for a Multi-Monitor Setup

Before we jump into the nitty-gritty, let’s get a handle on what you’ll need for a multi-monitor setup. First off, you’re going to need commercial security cameras and monitors, obviously.

But it’s not just about plugging one into the other. You’ll need a few more pieces when setting up a multi-monitor system for your security footage:

Network Video Recorders (NVR), Video Management Systems (VMS), or the Cloud 

Video recording and management tools like an NVR or VMS receive video data from cameras and transmit it to monitors.

Video Splitter

A video splitter is a device that takes a single video input and duplicates it to multiple outputs. For instance, if you have one camera and you want its footage to be shown on four different screens, a video splitter can be used. The splitter doesn’t change or process the video signal in any complex way. It simply replicates the incoming video signal to several outputs.


A multiplexer takes multiple video input streams and combines them into one signal to be recorded or displayed on a single monitor. The primary function of a multiplexer in a surveillance system is to allow multiple camera feeds to be viewed on a single screen simultaneously, reducing the need to switch back and forth between individual camera streams and applications.

Cables and Connectors

Depending on your setup, you might need HDMI, VGA, or other types of cables and connectors.

Step-by-Step Guide to Connecting IP CCTV Cameras to Monitors

Alright, let’s get down to business. If you’d like to hook up two or more security cameras to one TV or multiple monitors to view all of your security camera footage on the same screen, here’s how:

  1. Connect Cameras to Video Storage/Management Devices: Start by connecting your cameras to a video storage and management device, such as an NVR. This is usually done using a coaxial or Ethernet cable.
  2. Hook Up the Video Storage/Management Device to the Video Splitter: Using the appropriate cable (often HDMI or VGA), connect your video storage/management device to a multiplexer. (Multiplexers allow multiple video feeds to be simultaneously displayed on a single monitor.)
  3. Connect the Multiplexer to Your Monitors: Now, take your multiplexer and connect it to your monitors. Again, you’ll be using HDMI, VGA, or another type of cable.
  4. Power Everything Up and Test: Once everything’s hooked up, power on your system. You should see your camera feeds on your monitors. If not, double-check your connections.

Best Practices for a Seamless Multi-Monitor System

Now that you’ve got everything connected, here are some tips to make sure you’re getting the most out of your setup:

Opt for High-Quality Cables

Don’t skimp on the cables. High-quality cables mean a clearer picture and a more reliable connection.

Consider Monitor Placement

Think about where your monitors are placed. You want them in a spot where they’re easily viewable and accessible to security personnel.

Regular Maintenance is Key

Keep an eye on your system and stay up to date with firmware and other software updates. Regular checks will help you catch issues before they become problems.

Troubleshooting Common Issues

Even with the best setup, you might run into a hiccup or two. Here’s how to tackle some common issues:

No Signal on the Monitor: Check all your connections. Make sure everything’s plugged in properly and powered on.

Poor Video Quality: This could be due to low-quality cables or a weak signal from the camera. Check your cable connections and consider upgrading your cables.

Connecting cameras to multiple monitors enhances situational awareness by allowing security personnel to monitor different areas simultaneously, ensuring comprehensive surveillance and quick identification of security issues.

Multi-monitor setups in security systems increase efficiency by enabling different screens to display specific types of monitoring data, such as real-time video feeds and recorded footage, enabling thorough monitoring without missing critical details.

Using multiple monitors improves security processes by providing ample screen space for detailed CCTV footage, enhancing focus, and eliminating the need to switch between different video feeds or applications.

For a multi-monitor security system setup, essential equipment includes security cameras, monitors, a Network Video Recorder or Video Management System, a video splitter or multiplexer, and appropriate cables like HDMI or VGA.

To connect cameras to multiple monitors, connect the cameras to a video storage/management device (like an NVR), hook up the device to a video splitter, connect the splitter to the monitors using cables like HDMI or VGA, and then power up and test the system.

Multiple monitors improve response times in security monitoring by enabling staff to quickly spot and react to security breaches or concerns, as they can view different areas and incidents simultaneously.

For a multi-monitor security setup, it's recommended to use high-quality cables, such as HDMI or VGA, as they provide clearer pictures and more reliable connections.

Monitor placement is crucial in a multi-monitor security system because strategically placed monitors ensure they are easily viewable and accessible to security personnel, enhancing the effectiveness of surveillance.

Regular maintenance of a multi-monitor security system, including firmware and software updates, is key to catching and addressing issues before they escalate.

If there's no signal on the monitor in a multi-monitor setup, check all connections to ensure everything is properly plugged in and powered on, as loose or disconnected cables are often the cause.

To address poor video quality in a multi-monitor security system, check the cable connections for any issues and consider upgrading to higher-quality cables to ensure a stronger signal and clearer image.

A video splitter or multiplexer in a multi-monitor setup splits the video signal from the cameras, allowing the same feed to be displayed on multiple monitors simultaneously.

Yes, Ethernet cables can be used to connect cameras to video storage devices like NVRs in a multi-monitor setup, especially for IP-based camera systems.

Video storage and management devices, such as NVRs or VMSes, are important in a multi-monitor security system as they receive video data from cameras and transmit it to the monitors for viewing.
