Wireless outdoor night security cameras are a great way to keep your property safe at all hours of the day. They are a necessity if you want your security system to be more effective than just a deterrent. When you’re shopping for night security cameras, the best ones will almost always have infrared technology, which will let you capture images of what is happening on your property even in complete darkness, giving them a lighting rating of 0 lux.
These cameras work by picking up on a wavelength of light that is given off by objects that are heated up, like human bodies. Most of these cameras are dual function and come with two sensors in the camera itself. One sensor is for the daytime images that every outdoor security camera will catch during the day hours. But, infrared cameras have a second sensor in them that captures the infrared light and is activated automatically when ambient lighting in an area drops below a certain level.

An outdoor wireless security camera that comes with night vision enabled will usually advertise that it comes with ten, twelve, or more infrared LEDs. What these lights do is flood the area around the camera in infrared lights, which are then reflected back to the camera, intensifying the weak infrared light that is given off by heated objects already. It’s the equivalent to shining an invisible flashlight over the area that the camera is watching. The image comes out in shades of green because the naked eye can perceive more tones of green than any other color, making it easier to pick up the outlines of objects in an otherwise colorless night image.
The major downside with most wireless outdoor night vision security cameras today is that they have a limited range. There are cameras that can see up to over three hundred feet in the night that are available, but these are generally too expensive for home or small business use. Instead, most home security cameras will see around thirty feet at night. Another limitation, if you are trying to hide your cameras, is that the infrared sensors can give off a red glow if someone looks right at the camera, giving away the camera’s position.
Despite these two drawbacks, it is essential for any outdoor security camera that you buy to be equipped with night vision. Otherwise, you are limiting yourself to only seeing what goes on during the day. At night the cameras will still serve as a deterrent, but only if the criminals saw where they were located at during the day, otherwise you will be effectively running blind.
