20 Inch LCD Video MonitorCCTV LCD video monitors are simply one of the most important components of your security surveillance system. To make sure that you are getting your money’s worth, be sure to consider the factors listed below the next time you go shopping.

Response Time AKA Speed or Refresh Rate
This can be one of the most commonly mentioned aspects of CCTV LCD monitors but at the same time it’s also one of the least understood. Basically, response time or refresh rates of monitors talk about the speed of transition from one image to another. The usual speed rates are four, eight, and sixteen milliseconds.

If you are going to use a small CCTV LCD monitor – anything between fifteen and nineteen inches – you should consider something between 4 to 8 MS in terms of response time. Something slower, however, is adequate for larger sized monitors. Also, if you expect to view high-speed action footage then a higher response time is definitely called for.
Size Matters

The bigger the CCTV LCD monitor is, the pricier it will get. But of course, a bigger screen means easier or more convenient viewing, not to mention better and greater detail. The question is, however, if you can afford it. More to the point, do you really need a big CCTV LCD monitor? Last but not the least, do you have the space for it? Then again, if there is no desk space for your monitor, you could always mount it on the wall.

Resolution and Quality
Now what about image resolution? First and foremost, you need an CCTV LCD monitor that allows you complete control over all visual aspects, whether it has to do with color, brightness, contrast, or something else. This is non-negotiable. There will be times when changing the levels for these aspects can make you discern important elements in a captured shot, elements that you would have overlooked in normal resolution.
But still, it must also offer a one-touch function to resume the original or previous visual setup for your convenience.

Dead Pixels
You should be very wary of dead pixels! Even brand new CCTV LCD monitors may have them if they’ve been mishandled. Switch to an all-white screen and you’ll be able to see if there are pixels that are permanently black. If there are too many of them, they could render an image inaccurate.

Dot Pitch
Last but not the least, consider the dot pitch. The smaller a monitor’s dot pitch is, the crisper the image. It’s as simple as that!

CCTV LCD Video Monitor How to Find the Best One

A CCTV camera always comes hand in hand with an LCD monitor the same way a pen will never work without the appropriate paper surface to write on. TV sets may be compatible with them, but they certainly can’t work 24/7 the way LCD monitors do and has to, considering the purpose of CCTV. CRTs, the bulky monitors used for computers, may also work but they emit more radiation and consume more electricity. Thus, you’re left with the best choice of all for CCTV cameras, and that’s an LCD video monitor.

CCTV LCD Video monitorSelecting the Right CCTV LCD Video Monitor
In purchasing CCTV LCD video monitors, be sure to consider the factors listed below.

Size Matters
It is important to consider this size, especially if you have limited space to work with. A large LCD monitor, however, is preferable if you expect a frequent need to review real-time or previous footage.

Brand Consciousness
Heed this advice – If you can afford it, try not to buy LCD video monitors manufactured by little-known brands. You may find its very affordable price helpful, but such low prices usually come with poor product quality and customer support. If, however, you insist on purchasing a not-so-known name then be sure at least to check for what kind of after-sales support and warranty you’ll be given.

Resolution and Quality
A very basic term for resolution is the overall quality of photos and video footage captured by the CCTV camera. If your CCTV camera is connected to a CPU as well, you’ll have to make sure that your video card specifications are compatible and at par with that of your LCD video monitor. If not, the image would have to be resized and the result won’t be favourable.

Other features you may want to take note of and which may affect the overall visual quality of your monitor are brightness, response time, pixel pitch, and contrast ratio.

Audio Feature
Not all LCD video monitors come with built-in speakers and even those that do cannot always guarantee high sound quality. The only way to find out which has the best audio capabilities is to test them yourself. Search online for previews of other users to avoid making the same mistakes they did.

How about a Secondhand CCTV LCD Video Monitor?
It’s possible to find a used CCTV LCD video monitor that’s still in good working order, but it won’t be easy. Be especially careful when shopping online for used electronic equipment as there is no way for you to test the product prior to having it delivered to your doorstep.
