Which Monitor is best for CCTV(closed-circuit television)?

If you’re running an ongoing CCTV system or it’s being monitored for regular daily checks, there are a lot of factors to take into account, including resolution and refresh rate. We take a look at what these terms really mean and pick out the monitor that offers the best image quality for you. The Question Which Monitor is best for CCTV(closed-circuit television)?  is quite common.

As a general rule, higher refresh rates will mean smoother movement across the screen, allowing for fewer delays between commands, and fewer dropped frames when moving around the CCTV frame. But what’s really important is how effective a monitor is at showing detail. So, not only must your video feed be up to scratch, but your monitor has to be too.

That means there’s a wide range of available screens for you to choose from, depending on the type of work you’re doing with your CCTV. But, in order to find the best monitor for your job, we’ve put every model through its paces.

In this in-depth review, we’ve looked at the differences between IPS, TN, and VA panel types, and how they vary in terms of what they can and can’t do for your image quality.

For a full explanation of our testing process, read on.

What are IPS, TN, VA, and VA resolutions?

Screen resolution can be broken down into two major categories.

IPS – often called Patterned or Transparent IPS

Transparent IPS: a traditional white-on-black-pixel arrangement

In the world of LCD monitors, IPS are the most popular screen technology, offering the highest level of contrast and colour accuracy.

One of the many benefits of IPS is that it can ‘see’ through (or image through) reflections better than other screen technologies, so viewing angles are better. This allows a more effective application of upscaling to show logos and text on a black background.

Transparent IPS also has the benefit of a viewing angle which is unaffected by surrounding light sources, so shadows, reflections and glare are less of a problem.

The main problem with IPS is that it can be pretty expensive. While some TN monitors can cost the same as a budget-priced IPS model, you’ll rarely see TN monitors at more than £150.

Traditional TN panel screens are better at displaying black than IPS panels. In addition, they can have a contrast ratio that’s close to that of an IPS monitor, if not actually slightly better.

Another disadvantage of TN is that they can have very narrow viewing angles (typically less than 40°), so people sitting towards the edges of the screen will see images slightly distorted.

VA (Vertical Alignment) panels are designed to be perfectly balanced and show both colour and black levels simultaneously. They’re also said to have a much better viewing angle than TN monitors and IPS panels.

They offer slightly better contrast than IPS panels, but there’s no drastic contrast boost. However, they do improve colour accuracy.

In terms of appearance, VA panels are as glossy as IPS panels but have slightly thicker borders. They do offer a wider viewing angle than TN panels and IPS displays, but not as wide as the 28° advantage of IPS. I try to explain to you Which Monitor is best for CCTV(closed-circuit television)?

Other LCD screen technologies

Although IPS and TN have the lion’s share of the market, there are several other display technologies that have come onto the market in recent years.

The most notable is VA (Vertical Alignment). The benefit of this technology is that it allows you to show two completely different images simultaneously.

There are also a lot of different versions of VA available. A few are mainly aimed at digital signage, but the majority are designed for desktop monitors.

We’ve gathered together reviews for some of the most common VA panels available.

IPS/TN versus VA

When comparing monitors, it’s important to remember that resolution isn’t the only thing that matters.

Many people buy a monitor because of its resolution, ignoring any aspect of its image quality. However, the quality of your monitor’s screen Technology is likely to be a much bigger factor in how effectively you’ll be able to edit footage or check up on an ongoing situation.

On the one hand, an IPS monitor will deliver an improved black level, and offer more detail and punch in colour reproduction. On the other, an IPS monitor will deliver slightly better viewing angles than an IPS display, but this will depend on the viewing angle the screen is placed in, as it will often be in front of a bright backlight.

As a rule, you won’t see a huge difference in image quality from a £100 IPS monitor with a TN (Transparent Alignment) panel or a £200 IPS model. However, if you spend over £300 on a high-end IPS monitor, the difference in image quality from a VA (Vertical Alignment) model will start to become apparent.

As a rule of thumb, the better the contrast ratio, the better the image quality will be. This is because the brighter the display, the more blue light it reflects back. This creates a light haze in your image that detracts from detail, but an IPS monitor’s contrast ratio should not be affected as much as those from TN (Transparent Alignment) displays.
