How to Find the Best CCTV LCD Video Monitor
Your CCTV camera always comes hand in hand with an LCD monitor the same way a pen can’t work without the right 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.
How to Choose the Right CCTV LCD Video Monitor
When shopping for CCTV LCD video monitors, be sure to consider the factors listed below.
Size
This is very important 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
Avoid purchasing 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
A very basic term for resolution is simply 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 elements you should consider and which may affect the overall visual quality of your monitor are brightness, response time, pixel pitch, and contrast ratio.
Audio Capabilities
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.
Are You Interested in Buying 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.

How to Choose the Best Cable For Your System
Use of HDMI cables has exceeded the use of it’s predecessor as people look for the best reception and performance. But as you consider the options it’s not always that clear of a decision about the cable to use for all improvements in pictures for your television and computers.
DVI cable, (Digital Visual Interface), provides high visual quality on such devices as flat-screen computer monitors and other output devices. It is also used for video graphic cards and can be used to carry an analog signal. By using these cable versus VGA cable, there is no digital conversion that happens with a VGA cable. As the signal goes from digital to analog and back to digital with VGA cable, these transport the digital signal without converting to analog and back again. In recent years, most television sets and other devices have come standard with thisconnection, making analog more obsolete and video quality better.
The DVI cables are made for three different applications and so there are three different cables you can get depending on your need. DVI-A is analog only, carrying a DVI signal to a analog device, DVI-D is for digital only, taking a DVI signal to digital components, and DVI-I takes DVI signal to analog or digital. DVI can carry audio feed so it doesn’t have as wide a range as the HDMI cable.
But it is losing the tech battle to HDMI cable (High Definition Multimedia Interface) in several areas. HDMI cable can travel a longer distance and is slimmer than DVI. The video signal is the same but being able to travel the extra length without any degradation of signal is significant. Also the HDMI cable does carry audio signals which the DVI doesn’t. The two variations of HDMI cable are, Type A for mostly residential use having 19 pins, and Type B with 29 pins which provide higher resolution in commercial settings.
Video cables like these will both produce great results for video quality and each has its own unique specifications. Though both can be interchangeable, there are some things to consider before deciding on which one to use. Regardless of whether one chooses, both will provide great video quality for today’s digital devices.
