Advances in the field of home security have come a long way in the past few decades, and while criminals are getting smarter and smarter every day, home security systems continue to evolve to keep up with them. From cameras to motion detectors to even simple trip wires, today’s home security systems combine many different types of technology to create a practically bulletproof fortress to protect your home, family, and belongings.
One of the more important advances in home security, and a serious feature to consider when investing in one, is infrared sensors. The concept is similar to the technology behind “night goggles” used in the military to see clearly in the dark. You see, infrared light is invisible to the human eye, but infrared cameras are able to render it in a manner we can see on a screen. Thus, many modern home security systems utilize this technology to detect intruders at night.
While it may be easy to spot an unwanted trespasser on camera during the day, at night it may be more difficult and using a normal visible-light camera may lead to decreased efficiency or frequent false alarms. However, infrared based home security systems can see clearly both at night and during the day, and are efficient enough to distinguish a human from an animal based on size, shape, and mass.
So when shopping for the home security system that is going to protect you and your loved ones for years to come, make sure you are including this vital piece of modern technology in your considerations. Of course this is not to downplay the importance of other technologies such as door sensors and secured locks, but it is especially important not to be vulnerable at night when burglars are counting on the advantage of darkness to be in their favor.
