If you are considering an infrared security camera system then be aware you'll come across what are known as night vision cameras. There is a subtle difference.

Many people confuse the two but the truth is, night vision or day/night cameras don't have infrared capability. The former has the ability to produce images in total darkness while the latter doesn't. There is no suggestion here that one is better than the other and your circumstances will play a big part in which way you decide to go.

In this article, explain the difference between the two and their respective abilities as security components of your property.

Infrared Security Cameras

In a nutshell, it's the LED(light emitting diode) which gives it the ability to take images in darkness. With a little light to work with, these images can increase in clarity to resemble daytime conditions.

The use of infrared cameras are popular in businesses and residential properties which have what is known as "blind spots." Basically, a blind spot is an area that is not prone or devoid of any lighting and it's usually the first choice entry point for intruders.

Without effective security, going from these "blind spots" and entering the property is usually an easy assignment but with infrared coverage, capturing any intrusion on tape is a "soft snap."

Color Pictures

The ability to take color pictures during the day time and then revert to black and white at night is one of the main features of this camera. In fact, when the sun sets the camera will actually switch to infrared.

It's rare that any business or home property is in absolute total darkness simply for the reason that there is some light either being emitted from the street lighting or in the shape of the night time stars.

Weather plays a part in where you position your camera. Given that it's most likely going to be out in the elements then consider weatherproof style casing such as a bullet-shaped camera.

Should You Purchase Infrared?

There has always been an argument for and against an infrared security camera vs. a night vision camera. If you live in a suburban area with well lit streets then day/night cameras should be enough.

Consider whether you are ever going to be in a situation where your property will be immersed in total darkness. This is usually rare in any area. Another comparison that needs to be made is the expense of running infrared cameras opposed to night vision models. The former do require more power but it's questionable whether this will blow out your power bill.
