Tired of not being able to see things that go “bump” in the dark? If that’s the case, you need a night vision wireless security camera. These cameras take advantage of the latest technology in digital camera security systems, are easy to install, and are reasonably priced as well.
Can a night vision wireless security camera actually “see” in the dark? Well, indirectly the answer is yes. Although the camera doesn’t actually “see” in the dark, it uses infrared illumination to light the target area of the camera. This infrared illumination is actually invisible to the human eye, so we can’t see it, but the camera can. Before we get ahead of ourselves let’s back up and start at the beginning.

A wireless night vision outdoor security camera is a digital video camera with highly specialized features. Modern technological advancements have made these specialized features available at a very affordable price while offering high quality video images.
Outdoor security cameras differ from their counterparts the indoor security cameras, in that they are enclosed in a case that protects them from weather and environmental elements. Wireless night vision outdoor security cameras are often rated according to the protection that they offer. This protection is often described using an International Electrical Code standard called an Ingress Protection rating, International Protection Rating, or IP code. Most wireless night vision outdoor security cameras have an IP code of IP66 or IP67. IP66 means that the camera is dust tight and that water from powerful jets in any direction will have no harmful effects on the camera. IP67 means that the camera is dust tight and can withstand being submerged in water up to 1 meter in depth.

Security cameras usually have a LUX rating. This LUX rating is the actual available light intensity at which the camera can produce a picture.
A LUX, abbreviated lx, is the International System of Units (SI) measure of the intensity of light. It can be thought of as the strength of light as determined by the human eye. A LUX is based on another unit of light measurement called a lumen, which is based on yet another unit called a candela. In the United States, the non-SI unit to measure light intensity is the footcandle. One foot candle is approximately equal to 10.8 LUX.
