Protect your home use Security Cameras

I want to protect my home and use Security Cameras

So I want to protect my home.   I need a video surveillance system for night or in areas with low light. So looks like the best option would be infrared security cameras that capture images even in the dark.

So what is an infrared camera exactly?

An infrared camera works by calculating the brightness of a room or particular area. They feature special LED lighting which can be seen on the outside lens. These LEDs are able to capture light from the regions of electromagnetic spectrum that allow an image to be created even if there is little visible light. For this reason we refer to IR cameras as having night vision.

An infrared security camera will switch its mode to infrared only when the light drops below a certain level. It captures black and white images at that point.

Interesting side note, IR Illuminators allow many objects to be penetrated, such as the haze, fog and smoke. Infrared Illuminators are used typically for a low light environment. Sometimes, when the IR array is focused narrowly or the hold is not strong enough the external IR Illuminator will give an extra sharp image. It can provide an additional infrared light source that is invisible to the naked eye normally.

If you are going to use infrared security cameras outdoors, the best option would be to choose those that can stand up to the natural elements as well as tampering from criminals.   I found several options that allow for the greatest flexibility including direct bright light, vandal resistant, weather proof and cost effective.
