How to Choose a Security Camera Monitor

A monitor is very similar to a standard TV set, in the sense that it grabs video data from an analog source and displays it on a screen. As opposed to a TV, a security camera monitor doesn't have a tuner device, so they can only be used to grab data from specialized devices like video cameras, DVD players or VCRs. Also, most monitors can't output sound.

Why do you need a monitor, what's wrong with the TV?

As most monitors are specialized on displaying video signal, they are much simpler and are very robust. Their simpler design makes them reliable. The output quality is usually better. If you want a professional surveillance setup you will need security camera monitors, as they are easier to configure and maintain, and are created exactly for this purpose.

When you shouldn't buy a security camera monitor

If you have digital security cameras, the monitoring software will probably run on a computer system and a computer monitor would probably be a better idea.

If your setup is based on IP Cameras, there is no use in buying custom monitors, since you can view the camera output from a standard computer in the network. It might be a good idea to get a large, high-resolution computer screens for the surveillance personnel.

Types of security camera monitors

Monochrome CRT Monitors - they are the simplest and cheapest models, and can only display black and white video. Since many security cameras are black and white as well, it is a good idea to use monochrome monitors when your cameras don't output color video anyway. Prices range from $100 for a 12" monitor, to $300 for a large 20” monitor.

Color CRT Monitors - you should get a color monitor if your setup has color cameras. Prices range from $200 for a 10" display, to $400 for a multiple-input 20" display.

Color LCD Monitors - LCD Monitors are great because they take less space and are easier to setup. There is a wide range of LCD Monitors available, you can choose from small hand-held monitors to huge multiple-input screens. Make sure the LCD Monitor you choose can be connected to your security cameras, as many LCD monitors only allow computer input. Prices range from 220$ for a 7" monitor to over $1500 for high-resolution professional monitors

Big screen monitors - if you need to simultaneously view the output from multiple video cameras, big screen monitors are a very good alternative to a multi-monitor setup. They are pretty expensive; you will have to pay up to $2500 for a 32" monitor.

What features should you look for?

l First of all make sure the video monitor you choose can be easily connected to your security cameras. Make sure they both use the same video standard (PAL or NTSC).
