The times when outdoor home security cameras are most important are often at night. Whether it’s keeping an eye on unwanted nocturnal visitors like raccoons and coyotes, or looking out for the more worrying problem of burglars, there’s a lot of activity that happens at night that home security cameras can keep an eye on while you sleep. The problem is that, when the time most demands it, home security cameras often fall short. There are many home security cameras that claim to have great night vision, but the actual results don’t always stack up. The affordable fix is to invest in an IR illuminator.
IR illuminators emit light on the infrared spectrum, which makes it easier for security cameras to “see” in the dark. They can help illuminate those areas where normal nighttime lights don’t reach. A major benefit of IR illuminators is that they emit light that is invisible to the human eye. That makes them a good alternative to traditional floodlights, which can potentially cause some angry visits from red-eyed neighbors. The most important thing to check before buying is the wavelength. If your home security camera’s night vision uses a different wavelength, it won’t be of much use. The products below include the wavelength on their listings, so you can cross-reference with your own setup.
If you’re looking for an affordable way to enhance your outdoor home security system, IR illuminators are a great place to start.
