There are many types of monitors out there, so I will try to help with choosing the best one for security and CCTV camera setups. This guide goes over everything from the size of the monitor to refresh rates and everything in-between.

I've included my recommended monitors and TVs below for viewing security and CCTV camera feeds to make a more knowledgeable and straightforward purchase.

The best monitor size for viewing your security cameras depends on how far you'll be sitting from your monitor, which resolution you want, and how many camera feeds you'll be viewing on one display.

If you want to sit farther away from the monitor, you'll probably want to get a larger one so that you can see all of the camera feeds clearly.

Smaller monitors have the advantage of fitting more camera feeds into your field of view without having to move your eyes as much.

Larger monitors can allow you to have more camera feeds and other apps on the screen overall if you get a monitor with a higher resolution.

In the chart below, you can see the optimal resolution for each size of monitor.

Any resolution higher than the optimal resolution listed below might look a little crisper or allow you to display more camera feeds at once. Slightly crisper images alone would likely not be worth the extra added cost.

For example, you'll have the best experience if you get a 27-inch monitor with a 1440p or 4K resolution. Verify that your CCTV DVR or security device is capable of handling the higher resolution.

Monitor Sizing
Monitor Size Optimal Resolution
24 inch 1080p / 1440p
27 inch 1440p / 4K
32 inch 1440p / 4K
42+ inch 4K

Using a TV Instead of Monitor

TVs are also another great option for a security system setup. TVs are the best option for a larger display since larger monitors are not as common and are more expensive.

Power Usage

Section Link

LEDs are the primary backlight type in monitors nowadays, so most monitors use a similar amount of power. Most monitors consume an average of 45 to 65 watts during use.

Some Energy Star certified monitors can use as little as 16 to 35 watts, but the monitor won't be as brightly lit in energy-saving mode. A larger LED monitor or TV (over 30 inches) can use around 80 to 100 watts.

LED-backlit displays typically have a 100,000-hour lifespan. LCD backlit displays have around a 50,000 to 100,000-hour lifespan. That's equivalent to 5 to 11 years of constant use.

These estimates mainly depend on the quality of components (particularly capacitors in the display) and the temperature the display is being used in (the higher temperature, the worse). Quality-engineered LED displays, which are more expensive on average, usually last up to the estimated lifespan.


LED LCD monitors are less susceptible to screen burn-in compared to OLED. LED LCD and QLED displays are your best options for camera feeds with static images. If you use an OLED TV for viewing your camera feed, though, you may have some minor burn-in over time. However, newer models typically have settings and features to mitigate screen burn-in.

The best monitor for your setup can also depend on how much detail you want to be displayed and the clarity of what's on your screen, like user interface elements and text quality, along with your camera feed.

The clarity is based on the resolution, but a bigger screen allows you to see it at a more comfortable size. A 27-inch monitor with a 1440p resolution will look a lot more crisp compared to 1080p.

Security cameras usually have a 1080p, 2K, or 4K resolution. The resolution of the camera feed doesn't mean that you have to have the exact resolution for your monitor, though. For example, a 4K camera can still look clearer than a 1080p or 2K camera when viewing them on a lower resolution display (1080p or 1440p). With that said, if you want to get the full benefit of your 4K camera feed, then you'll be best off with a 4K display, especially if you have many camera feeds you want to view on one display.


You may plan to also use your monitor for computer apps, such as browsing websites or multitasking (having multiple windows open side-by-side).

The advantage to using a higher-resolution monitor (1440p or 4K) for your security setup is that you can fit more apps and windows onto the screen at once. Higher resolutions can help with multitasking and allow you to view multiple camera feeds and any other apps you want to view simultaneously.

If you don't scale the UI on your operating system, text and buttons will be smaller at high resolutions. However, newer operating systems let you scale the UI, which means that everything can be the same size as on a low-resolution monitor but have greater detail.

Panel Types

Section Link

The display panels inside monitors can use a variety of different technologies. Common LCD panel types include TN, VA, and IPS. Non-LCD panel types include OLED.

Note that LED and QLED are types of backlight technologies and are used in combination with TN, VA, and IPS panels.

Below is a comparison of the different monitor panel types. Overall, IPS panels are my favorite because they provide the best features for the price.

Refresh Rates

Section Link

Refresh rates determine how well a monitor can handle motion — the higher the refresh rate, the better. If you're using your monitor only for security cameras, refresh rates won't matter that much. If you're using your monitor for other uses also, then it can improve the overall experience. Scrolling through your web pages will look a lot more smooth. With that said, you won't notice a difference in refresh rates while there's no motion on the screen.

Monitors can have a refresh rate ranging from 60 to 360 Hz.

Refresh rate is the number of times a display can redraw the screen. Refresh rate is measured in hertz (Hz), which is defined as one cycle per second. For example, a refresh rate of 60 Hz means that the screen will redraw 60 times each second.

A good refresh rate is around 120 Hz to 165 Hz or above for all use cases, but 60 Hz will be good enough when using only for your security camera feed. Refresh rates of 75 Hz and higher will reduce motion blur and make animations smoother in other cases.

Response Times

Section Link

Response time also determines how well a monitor can handle motion — the lower the response time, the better. A lower response time can improve the smoothness and clarity of text while scrolling through web pages or documents.

Response time is the time it takes a display to change from one color to another. The timing of this is usually determined by going back and forth between white and black. The timing is measured in milliseconds, with lower being better.

If your monitor has a higher response time, you'll notice more ghosting. When ghosting occurs, it looks like the colors or text are blurring together whenever there's quick movement on the screen.

Try to get a monitor with a 1 ms response time for best results. Monitors with a slightly higher response time (e.g., 5 ms) can still make for a great monitor for your security camera feed if you don't mind some minor ghosting.

Some monitors are not capable of both being set to their highest refresh rate and achieving their fastest response time. Check the monitor specs to determine what it supports.

If you're viewing your monitor in a dark lit room, its reflectivity won't matter as much unless you have lights shining from behind you. In a brighter room, or if you have lights behind you while viewing, you'll want to get a monitor with an anti-glare panel for best results. If your monitor is glossy and reflective, it can be hard to see parts of the display.


Section Link

Most monitors currently sold are bright enough for most situations, like for viewing a security camera feed. If you're considering a monitor for viewing in a brightly lit room, you should turn off any energy-saving settings to maximize the supported brightness level of the monitor. You can then raise the brightness settings accordingly.

250 to 350 cd/m² is the standard range of most monitors and is best for general use. Brighter monitors of around 500 cd/m² are better for brighter rooms or if you want a brighter screen.

Monitor brightness is measured with cd/m², which means candela (luminous intensity) per square meter. A "nit" is another way to describe 1 cd/m² brightness.

BNC Analog Connection

Section Link

Some security cameras use a BNC (Bayonet Neill Concelman connector) coax cable. If you want to connect BNC analog cameras directly to a monitor, then you will have to get a monitor with BNC inputs. These monitors are usually smaller and don't handle higher resolutions, response times, and refresh rates. Below, you can find a monitor I recommend if you need BNC inputs.

If you want to bypass using analog cameras directly connected to a monitor with BNC inputs, you can use a receiver instead. You can connect your analog cameras directly to a receiver, then connect a monitor to the receiver via HDMI. Having the option of using HDMI will give you a wider selection of monitors to choose from instead of getting one specifically with BNC inputs.
